ECRL: Role in National Transformation

The highlight of our underground works is undoubtedly the Genting Tunnel, a 16.39km twin-bore tunnel that cuts through the granite spine of the Titiwangsa Range. This is the longest rail tunnel in South-East Asia...

In this cover story, Engineering the Future: The ECRL’s Role in National Transformation, we speak with Dato’ Sri Darwis Abdul Razak , Chief Executive Officer of Malaysia Rail Link (MRL), to explore how the East Coast Rail Link is redefining the nation’s economic, engineering, and environmental landscape. Far beyond a transportation project, the ECRL emerges as a catalyst for connectivity, innovation, and inclusive growth, bridging long-standing regional divides while advancing Malaysia’s capabilities in underground engineering, digital construction, and sustainable infrastructure. From recordbreaking tunnelling works and cross-border collaboration to talent development and environmental stewardship, this interview offers a compelling insight into how the ECRL is shaping a future-ready rail network and positioning Malaysia as a competitive, resilient player in the regional transport corridor.

Strategic Importance of ECRL

The ECRL is often described as a game-changer in Malaysia’s transportation landscape. What are the strategic priorities that MRL is focusing on to ensure the project delivers long-term economic and social benefits?

The ECRL is not merely a railway project but it is also a national economic catalyst that reshapes Malaysia’s logistics, mobility, and regional development landscape. From the management perspective, our strategic priorities centre on a trifecta of goals: Connectivity, inclusivity, and competitiveness.

Bridging the connectivity gap. Our primary operational goal is to close the long-standing connectivity gap between the East Coast and the Klang Valley. Historically, the economic disparity between the West Coast and the East Coast had been exacerbated by logistical friction. The Titiwangsa Range has always been a formidable barrier, making road travel long and unpredictable. The ECRL changes this equation fundamentally.

Fostering economic clustering. We emphasise economic clustering by integrating industrial parks, ports, and population centres along the alignment. This is what we call the Landbridge Concept — linking Kuantan Port (South China Sea) directly to Port Klang (Straits of Malacca). This allows cargo to bypass the longer maritime route around Singapore. To realise this, we have launched the Economic Accelerator Projects (EAP). For instance, we recently signed a Memorandum of Understanding (MoU) with the Terengganu state government to develop

Transit-Oriented Developments (TODs) around ECRL stations in Terengganu. These hubs will generate vibrant micro-economies, ensuring the rail line has a high utilisation rate from day one.

Driving socio-economic impact. We prioritise long-term socio-economic impact by creating jobs, supporting local supply chains, and stimulating investments in lessdeveloped regions. To date, more

than RM19 billion in contracts have been awarded to approximately 3,400 local companies for ECRL Project. Ultimately, the ECRL strengthens Malaysia’s position within the regional transport corridor, ensuring that the benefits of development are shared widely rather than concentrated solely in the Klang Valley.

Vision for Underground Connectivity

The ECRL project involves extensive tunnelling across diverse terrains. From your perspective, how does this project redefine Malaysia’s approach to underground connectivity and regional integration?

The ECRL’s extensive tunnelling works, particularly through challenging geological formations, represent a milestone in Malaysia’s engineering capability.

Redefining Engineering Capability. This project redefines our national approach by demonstrating that underground connectivity can be delivered safely, efficiently,

We are designing a system which will reduce the travel time from Kota Baru to the Gombak Integrated Terminal to just 4 hours;

the journey typically takes 7-12 hours by road. With operations for Phase 1 (Kota Baru to Gombak) scheduled to commence in January 2027, and Phase 2 (to Port Klang) by January 2028, we are effectively compressing space and time.

and at scale. The highlight of our underground works is undoubtedly the Genting Tunnel, a 16.39km twin-bore tunnel that cuts through the granite spine of the Titiwangsa Range. This is the longest rail tunnel in South-East Asia, and we have managed to complete it within 42 months. To achieve this, we utilised high-technology Tunnel Boring Machines (TBMs), which are massive factories-on-wheels capable of excavating hard rock while simultaneously installing pre-cast concrete tunnel linings. This method reduces the risks associated with ground settlement and allows for rapid progress even in deep-cover conditions.

Environmental Preservation via Engineering. More importantly, the tunnels enhance environmental preservation by reducing surface disruptions while enabling more direct and efficient alignments. By going underground, we avoid fragmenting surface forests and disrupting water catchment areas. It allows us to maintain ecological continuity

which is critical for biodiversity. The engineering decision to tunnel is as much an environmental decision as it is a logistical one.

Foundation for the Future. Through this project, we are laying the foundation for future underground infrastructure, whether rail, utilities or integrated transport systems as Malaysia prepares for urban densification and transitoriented developments.

Cross-Border Collaboration

The theme of this edition emphasises Beyond Borders. How does MRL envision fostering cross-border engineering collaboration and knowledge exchange through projects like ECRL?

Beyond Borders reflects our belief that large infrastructure projects thrive through shared expertise. The ECRL Project is a product of a robus Government-to-Government framework between Malaysia and China, but the collaboration extends far deeper than diplomatic handshakes.

Knowledge Transfer and Innovation. MRL collaborates closely with international engineering teams, academia, and technology partners to foster knowledge exchange, design innovation, and skill transfer. Our partnership with China Communications Construction Company (CCCC) has brought world-class railway technology to our shores. Through structured programmes including joint design reviews, expert workshops, and local contractor upskilling, we ensure that our local professionals benefit from global best practices. For example, the use of the track-laying machine CCPG-500A has allowed us to lay track at a speed and precision previously unattainable here.

Reciprocal Contribution. At the same time, Malaysia contributes valuable regional experience in tropical engineering, environmental management, and community engagement. Engineering in a tropical climate presents unique challenges such as high rainfall and specific soil mechanics which require localised solutions. This mutual exchange strengthens not only the delivery of ECRL but also Malaysia’s broader engineering ecosystem.

Regional Integration. On a macro scale, the Government is actively discussing the potential extension of the ECRL to Rantau Panjang at the Malaysia-Thailand border. This connection would physically link our rail infrastructure with the State Railway of Thailand’s network, facilitating seamless crossborder trade and tourism.

Innovation & Technology Adoption

Large-scale infrastructure projects increasingly rely on innovation. How is MRL leveraging technology and modern practices to enhance efficiency, safety, and sustainability in delivering ECRL?

The ECRL is built on a foundation of modern engineering innovations. We are moving away from labourintensive traditional methods towards a technology-driven construction and operational model.

Digital Construction and BIM. MRL leverages technologies such as Building Information Modelling (BIM), advanced geotechnical monitoring systems, and automated construction techniques to enhance precision and safety. BIM has been instrumental in managing the complex interfaces of this 665km alignment. It allows us to simulate construction sequences and identify clashes before they occur on site. Other examples include:

• TBM tunnelling for the Genting Tunnel which exemplifies technology-led risk management, improving precision, safety, and efficiency.

• Elevated viaducts in flood-prone areas, selected despite higher costs, reflect smart, resilience-

focused design decisions informed by long-term risk modelling.

Data-Driven Operations. Digital solutions are central to our operations, whether in predictive maintenance planning, real-time environmental monitoring, or optimising construction productivity. As we transition to the operational phase, we are currently looking into AI-driven systems to monitor track geometry and rolling stock health. This “predictive maintenance” approach ensures high reliability and safety.

Future-Ready Systems. By adopting global standards and emerging technologies, we ensure that ECRL is not only delivered efficiently but is also future-ready as a next-generation rail system. We are

Sustainability & Environmental Stewardship

Tunnelling and rail development often intersect with environmental concerns. How does MRL balance engineering ambition with sustainability and environmental responsibility?

Environmental responsibility is one of our core commitments. We recognise that we are building through one of the world’s oldest rainforests, and we have taken extraordinary measures to minimise the ecological footprint.

Engineering for Conservation. MRL works closely with environmental agencies and conservation experts to ensure that every engineering decision balances progress with preservation. By collaborating with environmental consultants, we have

implementing electrification systems that support electric locomotives (e-Locos). These are essential for freight transport along the rail line and can operate at a maximum speed of 80 km/h. There are 12 e-Locos for the ECRL project with the units being installed at the Kuantan Port City depot as part of technology transfer initiative.

Sustainability. On the sustainability front, the e-Locos utilise regenerative braking, which improves energy efficiency and reduces our operational carbon footprint. We also embraced innovation-driven material selection: Recycled steel, prefabricated beams, and low-carbon concrete which reduce embodied emissions by up to 30%.

managed to optimise the alignment to achieve 90% less forest loss compared to original proposals –from over 2,000 hectares to just 270 hectares. On another note, the ECRL’s electrified system is projected to avoid nearly 929,000 tonnes of CO2 annually or the equivalent of removing almost 200,000 cars from the road.

Active Mitigation Measures.

We implement stringent measures such as controlled blasting, sedimentation management, and reforestation. The goal is clear: To deliver worldclass infrastructure while protecting Malaysia’s natural heritage for generations to come.

A standout initiative is the construction of 28 wildlife crossings at strategic locations identified

by the Department of Wildlife & National Parks (Perhilitan). These are not merely functional engineering structures but are also ecological bridges designed to ensure that the Malayan tiger, tapirs, and elephants can roam freely. Furthermore, we have installed elephant barrier fencing in areas like the Kemasul Forest Reserve to prevent humanwildlife conflict. This initiative has earned MRL national recognition by being listed in the Malaysia Book of Records for the Most Wildlife Box Culvert Crossings in a Single Railway Project. This reflects MRL’s strong commitment to environmental stewardship and our proactive approach in mitigating humanwildlife conflict through thoughtful engineering design.

Further, independent committees such as Environmental Performance Monitoring Committee (EPMC) and Environmental Regulatory Compliance Monitoring Committee (ERCMC) which conduct monthly and annual compliance checks respectively under the Environmental Quality Act Framework.

Talent Development & Industry Growth

Major projects such as ECRL create opportunities for local engineers and contractors. What initiatives have MRL undertaken to nurture talent and strengthen Malaysia’s engineering capabilities for future underground projects?

ECRL is a platform for building Malaysia’s next generation engineers and contractors. Through structured training programmes, technical apprenticeships, and joint-development initiatives with universities, we are cultivating local talent capable of leading future underground and large-scale infrastructure projects.

Structured

Training

Programmes. Our next generation engineers already have hands-on exposure to mega tunnelling, rail construction, systems integration, and environmental management through collaborations with local universities such as UTM, UMT, UMPSA, UTHM and others. Such collaborations strengthen knowledge transfer, research collaboration, and industrial placement opportunities for Malaysian students.

Through structured training programmes and joint-development initiatives with universities, we are cultivating local talent capable of leading future underground and large-scale infrastructure projects. Our flagship initiative is the ECRL Industrial Skills Training Programme (PLKI-ECRL). In May 2025, we sent a cohort of 210 Malaysian trainees to Liuzhou, China for an intensive oneyear training in railway technology to prepare a local workforce for the railway’s operations and maintenance phase. Sponsored by the CCCC, the

programme includes both technical and non-technical disciplines, and trainees are guaranteed employment upon completion of the training. Additionally, we recently celebrated 30 young Malaysians who switched careers to become assistant locomotive drivers. This proves that we are upskilling our local youth to handle high-value technical roles. They have since returned to Malaysia for practical, hands-on training.

Empowering Local Industry. We also work closely with local contractors to enhance their technical capabilities, safety culture, and project management skills. Over 3,400 Malaysian companies are involved in the supply chain, receiving more than RM19 billion in contracts, far surpassing initial targets. More than 16,000 workers are engaged across the project, supported by training and apprenticeship programmes developed with CCCC. This ensures that the benefits of ECRL extend beyond the project itself, strengthening Malaysia’s engineering industry and preparing our professionals for international opportunities.

Future Outlook for Rail Infrastructure

Looking ahead, what is your vision for Malaysia’s rail infrastructure beyond ECRL? How do you see underground and cross-border connectivity shaping the nation’s economic and social landscape in the next decade?

Looking ahead, rail will play a transformative role in Malaysia’s economic and social landscape. My vision is for a Malaysia where rail is the primary backbone of logistics and inter-city travel.

Seamless National Network. Beyond ECRL, we envision a seamlessly connected national rail network that integrates the East Coast, West Coast, and regional corridors. The completion of Phase 2 in January 2028 will be the tipping point. It will operationalise the Landbridge, making rail the preferred mode for moving goods across the peninsula.

Urban and Regional Transformation. Underground and cross-border connectivity will increasingly shape Malaysia’s urban development, logistics efficiency, and sustainability goals.

In the next decade, we expect rail to support greener mobility, reduce highway congestion, enhance regional trade routes, and unlock new economic zones. ECRL is the foundation; what comes next is a more connected, competitive, and resilient Malaysia.

Tunnel Lining Inspection System (TuLIS): Advancing Smart Tunnel Asset Management in Malaysia

by:

Ir. Assoc. Prof. Dr. Rini Asnida Abdullah

Ir. Ts. Azrul Md Din Deputy Chairman of TUSTD, IEM and Project Leader of TuLIS, from Universiti Teknologi Malaysia.

Head of Unit Structure, Maintenance & Asset Management PLUS Berhad, is industrial technical advisor for TuLIS.

The safety, reliability, and long-term performance of tunnels depend heavily on effective inspection and maintenance practices. Conventional inspection methods, while valuable, are often constrained by manual data collection, limited precision, and challenges in integrating multi-source information. In response to these limitations, the Tunnel Lining Inspection System (TuLIS) was developed as Malaysia’s first digital platform dedicated to tunnel lining inspection and structural health monitoring. It integrates conventional visual inspection with advanced sensing technologies including Close-Range Photogrammetry (CRP), Terrestrial Laser Scanning (TLS), thermography, and accelerometer-based monitoring to deliver precise, data-driven assessments.

This article presents the conceptual framework, field implementation, technological integration, and future potential of TuLIS as part of a broader movement toward smart infrastructure management. The system not only enhances inspection accuracy and efficiency but also lays the foundation for predictive maintenance and digital twin applications, positioning Malaysia as a regional leader in intelligent tunnel asset management.

Tunnels: Critical Infrastructure

Tunnels play a vital role in sustaining Malaysia’s transportation network, particularly in regions where hilly terrain or urban density makes above-ground routes impractical. As critical infrastructure, their safe and reliable operation is a matter of public safety and national economic stability. Tunnel inspection is, therefore, a cornerstone of asset management, providing the diagnostic insights needed to prevent failures and extend structural life. Table 1 summarises recent tunnels in operation for highway, railway and other infrastructure in Malaysia.

Traditional inspection approaches involve routine visual observation supported by selected non-destructive testing (NDT) techniques. These methods, though widely practised, often depend on manual data collection with extensive paperwork, subjective interpretation, and physical recordkeeping. Such approaches can be time-consuming, prone to inconsistencies, and limited in their ability to support strategic maintenance planning.

As we move toward more data-driven infrastructure management, there is a clear need to modernise tunnel inspection systems for improved precision, efficiency, and integration. TuLIS was conceived to address these challenges by combining the strengths of conventional engineering practices with modern digital technologies. It introduces a structured inspection workflow which integrates sensing technologies, advanced data processing, and cloudbased reporting, enabling more accurate, accessible, and actionable insights for tunnel operators.

The Concept

TuLIS is Malaysia’s first integrated digital platform developed to support tunnel lining inspection and structural health monitoring. This also highlighted the industry-academia-consortium of PLUS (M) Sdn. Bhd., Universiti Teknologi Malaysia (UTM), Universiti Kebangsaan Malaysia (UKM) and Universiti Teknologi MARA (UiTM), which worked together to solve industry problems through research and innovation.

The pilot implementation at the North-South Highway highlighted its potential to replace manual, paper-based inspection forms with a centralised digital system. By doing so, it overcomes common operational limitations as mentioned earlier.

The system is designed around a continuous workflow that connects field inspection directly to data management and analysis (Figure 1). Instead of treating inspection as a stand-alone activity, TuLIS embeds it within a larger asset management cycle where data acquisition, interpretation, decision-making, and maintenance planning can be interconnected. This is particularly critical for long linear infrastructure like tunnels, where localised defects can have broader structural implications over time.

Methodological Framework

The TuLIS methodology integrates engineering fundamentals with advanced digital technologies to ensure thorough and repeatable inspections. It begins with preparatory desk study, during which design records, historical inspection reports, geological data, and operational information are analysed to establish a baseline understanding of the condition of the tunnel. This is followed by structured field inspections using both conventional and advanced methods.

Conventional techniques include visual observation, rebound hammer testing, ultrasonic pulse velocity (UPV) measurements, temperature monitoring, and crack meter readings. These provide essential preliminary information. TuLIS enhances this with close-range remote sensing technologies such as CRP, infrared thermography, TLS, and accelerometerbased monitoring. These tools capture high-resolution spatial and temporal data, allowing the detection of both visible and subtle structural anomalies.

The data collected is stored on a web-based platform which standardises reporting and facilitates multi-user access. This integrated approach ensures that data flows seamlessly from the field to the decision-making level, supporting evidence-based asset management strategies.

Close-Range Photogrammetry (CRP)

CRP is a cornerstone of TuLIS technology. It involves capturing overlapping high-resolution photographs from close proximity to the tunnel lining and processing them into accurate threedimensional models and orthoimages. This allows for precise measurement of crack geometry, surface irregularities, and material degradation, providing a level of quantitative detail that conventional visual inspections cannot match. Two complementary approaches are applied within TuLIS. In the first, trained inspectors manually annotate defects on the 3D models to provide expert-verified references. In the second, a deep learning algorithm is used to automatically detect and map defects based on previously trained patterns. The combination of human expertise and semi-automated analysis enhances both accuracy and processing efficiency. Over time and as it is exposed to more inspection data, the machine learning component improves, making TuLIS progressively smarter.

Integration with TLS & Other Sensing Technologies

For a more complete picture of tunnel behaviour, CRP data is integrated with other sensing technologies. TLS provides millimeter-level accuracy over large tunnel sections, enabling engineers to detect structural deformation and displacement over time. This broader spatial context complements the fine detail provided by CRP.

3: Geometric features analysis on surface variation – 3D mapping of defection areas on lining (local neighbourhood radius value of 0.0035m)

Thermography offers the ability to detect moisture on the linings, based on the density of the point cloud, while accelerometerbased monitoring captures vibration signatures which may indicate the developing of anomalies. The water defect was successfully identified through point cloud analysis (Figure 3). However, the defect severity is minimal, and prompt rectification work is expected

to restore the structural integrity of the tunnel lining. By integrating these multiple data sources, TuLIS produces a multi-dimensional structural health profile. This combination enhances the reliability of assessments and supports more effective intervention planning.

Web-Based Inspection Platform

One of the key strengths of TuLIS is its web-based inspection and reporting platform. Inspectors can securely log in through mobile devices and input inspection data directly from the field (Figure 4). Photographs, defect assessment and NDTs data are uploaded in real time, eliminating transcription delays. The data is immediately accessible to asset owners, engineers, and regulators through a centralised dashboard.

The platform design focuses on usability. It simplifies navigation, supports structured data entry, and provides visualisation tools which allow stakeholders to interpret inspection findings intuitively. Past records can be retrieved, compared, and analysed over time, enabling the identification of progressive deterioration trends and supporting predictive maintenance planning (Figure 5).

Challenges & Lessons Learnt

The development of TuLIS involved overcoming several practical challenges. Managing large CRP and TLS datasets required robust cloud computing infrastructure and optimised data workflows. Training the deep learning model for automated defect detection demanded carefully curated image datasets and iterative refinement.

Environmental conditions inside tunnels such as low lighting, humidity, and limited space, posed additional difficulties for image acquisition. These were addressed through standardised protocols and specialised equipment. Transitioning inspection teams from manual to digital systems required capacity building, training, and operational adjustments. These experiences provided valuable lessons which now guide the ongoing refinement and scaling of the system.

Conclusion

TuLIS represents a milestone in our journey toward modern, data-driven infrastructure management. By integrating advanced imaging and sensing technologies with intelligent analytics and digital platforms, it overcomes the limitations of traditional inspection practices. The system delivers enhanced accuracy, faster reporting, improved safety, and long-term value through predictive maintenance and digital twin applications.

As Malaysia continues to expand its network of tunnels and underground facilities, TuLIS stands as a national innovation with both local and international relevance. Its success demonstrates the power of integrating engineering knowledge with technological innovation to create safer, smarter, and more sustainable infrastructure systems.

Maximising Renewable Energy & Emerging Green Technologies for Malaysia’s Off-Grid Islands

by:

Head (Asset (Planning & Operation)) Operations Department, Distribution Network

Pulau Tenaga Hijau (PTH), also known as Smart Green Island, is an island electrification project initiated by the Ministry of Energy Transition & Water Transformation (PETRA) and approved by the Malaysian government in August 2022. Led by the Energy Commission (Suruhanjaya Tenaga) and implemented by Tenaga Nasional Berhad (TNB), the initiative will provide 100% supply availability through cleaner sources of energy, supported by smart grid technologies, starting from 2028 in Pulau Perhentian and Pulau Redang, Terengganu.

The project is part of Malaysia’s broader national development agenda and commitment towards achieving net-zero emissions.

The goal of the PTH project is to attain self-sustainable energy via 100% renewable energy (RE) resources and green technology by 2040 through phased adoption, aligned with increasingly sophisticated systems. The project is charted on a technological roadmap, progressing

Note:

from fundamental solar panels to more advanced and clean technologies such as the utilisation of liquefied natural gas (LNG) as a transitional fuel, enabled via flexibility management.

This is further supported by smart grid facilities which integrate automated control systems and energy storage solutions to stabilise, smoothen and balance the electricity supply and demand.

The acceleration of RE and clean energy penetration in PTH project will ultimately support the following strategies:

• Achieve RE generating capacity of 70% by 2050 as per National Energy Transition Roadmap (NETR).

• Develop Energy Transition Network as per Reimagining Tenaga 2.0 Framework.

• Strengthen Sustainable Development Goals (SDGs) of fostering environmental protection and improved quality of life.

Transitioning to Smart Power Utility Business Mode

Currently, the assets on PTH consist of conventional diesel generators alongside smart technology features such as smart meters and energy-efficient LEDs, deployed across both islands. Geographic Information System (GIS) capabilities are fully integrated into all the assets. A total of 110 kWac at Pulau Perhentian, 285 kWac at Pulau Redang and 1,176 kWac at Pulau Tioman of RE has been installed, leading to reduced carbon emissions and operational expenditure (OPEX) savings. This latest initiative will comprehensively integrate the existing ecosystem to accelerate RE penetration through phased implementation by 2028, 2030, 2035 and 2040.

Conceptual Design

The project is built on three primary pillars: Operation Cost Reduction, Improved System Reticulation, and Smart Grid Technology. The PTH initiative focuses on implementing green and efficient energy solutions in Pulau Perhentian, Pulau Redang and Pulau Tioman. Figure 1 illustrates the conceptual design based on three pillars which adopts tailored strategies for each island.

For Pulau Perhentian and Pulau Redang, key strategies include reducing operational costs through LNG-to-power systems and integrating solar photovoltaics (PV) with verticalaxis wind turbines (VAWT). System reticulation improvements connect customers to optimised distribution systems. Additionally, energy management systems (EMS) and energy storage systems enhance sustainability.

For Pulau Tioman, operational cost reductions leverage diesel generation alongside solar energy (255kWp and 410kWp installations) and a 500kWp mini-hydro system. Smart grid technologies such as SCADA/distribution automation, advanced metering infrastructure, geographical information systems (GIS), and LED street lighting, further optimise energy distribution and infrastructure across all islands, promoting a cleaner and more efficient energy ecosystem across all islands.

Towards Net Zero 2040

The Energy Transition Journey Towards Net Zero 2040 outlines the phased shift to renewable and cleaner energy sources for Pulau Perhentian, Pulau Redang and Pulau Tioman, progressively replacing conventional energy with sustainable alternatives.

In 2022, all three islands relied heavily on conventional energy, with Pulau Tioman integrating a modest 9% cleaner energy sources of renewables. By 2023, renewable and cleaner energy adoption increased slightly, with Pulau Perhentian achieving 9% cleaner energy and Pulau Redang reaching 5%. Pulau Tioman maintained its 9% cleaner energy contribution.

The transition has gained momentum in 20242026. Pulau Perhentian plans to integrate 24% cleaner energy, Pulau Redang to achieve 37% and Pulau Tioman to reach 12%. The remainder of the energy needs is still through conventional sources. By 2028, all

three islands should demonstrate substantial progress, with cleaner energy accounting for 16% to 17% of their supply, while conventional energy remains at 83% to 84% accordingly.

The journey culminates in 2040, when all three islands achieve 100% reliance on cleaner energy, including renewable sources, fulfilling the vision of Net Zero 2040. This phased timeline as illustrated in Figure 2: Energy Transition Journey Towards Net Zero 2040, underscores the commitment to a sustainable energy transition, balancing cleaner and renewable energy technologies while reducing dependency on conventional sources.

Savings Through Renewable Installations

The renewable energy installations implemented so far, primarily through solar photovoltaics, have led to significant diesel savings amounting to RM392,138.65. This achievement reflects 16-28% reduction in diesel consumption, highlighting the substantial impact of integrating solar energy into the energy mix.

As the project progressively reduces dependency on diesel generators with upcoming solar projects in 2026, and in tandem with battery energy storage systems and Energy Management Systems (EMS), the team aims to achieve an additional diesel reduction of 20-30%. This will further result in a reduction in greenhouse gas (GHG) emissions of approximately 15-30% from the current level, underscoring the team’s dedication to achieving cleaner, more efficient, and sustainable energy solutions while contributing to environmental preservation. Figure 3 shows commissioned Building-Integrated Photovoltaic System (BIPV) installed in Pulau Perhentian, Pulau Redang and Pulau Tioman.

Conclusion

The PTH project represents a bold and transformative effort to transition the islands of Perhentian, Redang, and Tioman towards a future of clean and renewable energy. By integrating advanced green technologies, including solar photovoltaics, LNG-to-power systems, energy management systems (EMS), and smart grid solutions, the project demonstrates a clear commitment to sustainability and innovation.

The phased roadmap to 100% cleaner energy, culminating in Net Zero emissions by 2040, showcases a progressive approach that balances immediate operational benefits, such as significant reductions in diesel and GHG, with long-term environmental goals. Early successes, including diesel savings of approximately RM392,138.65 and a 16-28% reduction in consumption, underscore the potential of these initiatives to revolutionise energy use in the islands.

As PTH accelerates RE penetration with upcoming solar projects and battery energy storage systems in 2026, the islands are poised to achieve a projected further reduction of 20-30% in diesel usage and 15-30% in GHG emissions. This not only advances Malaysia’s sustainability agenda but also aligns with global Sustainable Development Goals (SDGs) of fostering environmental protection, enhancing energy security, and improving the quality of life for island communities. PTH stands as a model for self-sustainable, eco-friendly energy transitions for Malaysia.

Irene also emphasised that engineering went beyond equations and blueprints. It was a profession that touched lives, empowered communities, and drove sustainable progress. She reminded students that behind every technological advancement was a team of engineers who envisioned solutions for real-world problems. From clean water systems and renewable energy to digital transformation and green hydrogen technologies, women were increasingly at the forefront of innovation, redefining the landscape of modern engineering.

The presence of women engineers in leadership and technical roles had proven instrumental in shaping a more inclusive and resilient industry. Irene highlighted that diversity in engineering fostered creativity, enhanced decision-making, and led to more holistic solutions. She shared examples of how women professionals in PETRONAS and within the Institution of Engineers Malaysia (IEM) were driving change. These contributions not only strengthened the engineering ecosystem but also challenged stereotypes and inspired the next generation of female talents.

The interactive session concluded with an engaging question-and-answer segment where students eagerly asked about topics ranging from choosing an engineering discipline to balancing personal life and career growth. Their curiosity and confidence reflected a growing awareness among the young women that engineering was not just a profession, but a platform to lead change and to create meaningful impact.

Many students said they felt inspired after hearing Irene’s stories of resilience, innovation, and purpose. Several shared their aspirations to become chemical, civil, or environmental engineers, recognising that the path might be challenging but would be deeply rewarding. Teachers observed how the session ignited newfound enthusiasm among the students, reinforcing the importance of early exposure to role models and mentorship.

Irene’s participation in Program Explorasi Kerjaya 2025 aligns closely with the mission of IEM Women Engineers (IEM WE), which is dedicated to promoting inclusion, empowering young women to pursue STEM careers, and creating supportive platforms to nurture leadership potential in women engineers.

Engineering through Time: Intramuros, Philippines

Whenever the opportunity arises to attend CAFEO, I will allocate time to explore the host city as well. This year, CAFEO 43 was held in Clark, Pampanga in The Philippines. The best route from Kuala Lumpur was to fly into Manila and then travel by bus to Clark.

In Manila, I decided to travel solo to Intramuros, an old town that’s also known as the Walled City. Located on the southern bank of the Pasig River, Intramuros was strategically built as a military fort to protect Manila from foreign invaders. It once served as the centre of government administration during the Spanish colonial period, from 1571 to 1865.

The Baluarte de San Diego, a circular stone bastion as part of the wall defence system

The area housed government residences, religious institutions, and educational centres. Fort Santiago and its dungeons, San Agustin Church, and Baluarte de San Diego, a circular tower located within the walls, were constructed primarily from adobe, molave timber, and coral stone. This surrounding wall stretched for 2.5km and reached up to 8m in height.

The Vice Chair II for IEM-WE Section has a passion for Reliability & Asset Management, Instrumentation & Control, and Telecommunication Systems.

And no, it’s not adobo, the famous Filipino dish! Adobe is a building material made from consolidated local volcanic tuff and ash, a byproduct of explosive volcanic eruptions which was mixed with sand and other minerals easily available near Manila. This material was not only abundant but also proved remarkably resilient against tropical humidity and earthquakes, making it an example of early engineering materials well-suited to local conditions.

Over the centuries, Intramuros endured numerous natural and human-made disasters which put this naturally found material to the test. These included major earthquakes in 1645 and 1863 which destroyed much of its infrastructure and, during the Battle of Manila (1945) in World War II, almost the entire district was reduced to rubble. Yet the walls remained standing.

With the support of the Manila city government, reconstruction efforts on the National Historical Monument and National Cultural Treasure began under the Intramuros Administration. The restoration was a massive undertaking to balance structural safety with historical authenticity. Modern engineering techniques were used to preserve ancient structures while improving accessibility, drainage, and utilities.

Sustainability was also an important part of the reconstruction. The integration of eco-friendly materials and green technologies supports both conservation and modernisation.

Intramuros is more than just a restored city. It is a living symbol of identity, resilience, and heritage in a rapidly urbanising world. Through thoughtful engineering, Intramuros continues to stand strong today, not against invaders but against the passage of time itself.
