Abstract - Analysis and design of berthing structures
Administration is not having any of its own passenger terminal/wharf for berthing of Lakshadweep vessels at Beypore and accordingly, the Administration has been utilizing the present available facility of Cargo Terminal/Wharf facility at Beypore for berthing the vessels. The passenger/cargo ships of Lakshadweep Administration have to wait for long hours for a wharf and the cargo ships sometimes have to wait for days together to get a wharf at Beypore which leads to lot of hardship and inconvenience to the local passengers and also timely loading and unloading of cargo bound for Lakshadweep are adversely affected. The Administration is further augmenting the shipping fleet as recommended in the 15 years Perspective Plan for shipping requirements in Lakshadweep and accordingly one 2000 LPG Cylinder Carrier ship named Elikalpani has already been commissioned in 2012 and one 150 MT Oil Barge put into service in 2014. Moreover there is also proposal to acquire 2 Nos. 800 MT Multipurpose Cargo Barges and which is expected to start service by the end of 2015 and one 1000 MT Oil Barge by the end of 2016. Hence with the expansion of the shipping fleet with the acquisition of above vessels it would be difficult for the Administration to find suitable berthing facilities at Beypore for timely berthing and transportation of cargo. Now only one berth is available at Beypore Port for berthing of UTL passenger as well as cargo vessels, which makes it very difficult to get timely berth especially for loading of cargo.
seems to be a new subject to common structural engineers, but they are the important structures contributing to the development of trade in our nation. This design project is focusing on analysis and design of 2nd passenger berth at Beypore port, Kozhikode. It’s an open piled bored cast-insitu structure and lying in the seismic zone III. The berth is to be designed for a vessel having capacity of 5000DWT. The structure is subjected to various forces and combinations such as, High tide, Earthquake, High winds, heavy live loads as per IS: 4651-1983. A model was generated using STAADPro software and analysis was conducted with appropriate loads acting on the structure. It was observed that seismic force was nominal since Beypore being located in seismic zone III. This research is an attempt to understand the concept of design and analysis of berthing structures under different conditions of loading. Key Words: Berth, Load, Wind, Tide, Earthquake
1. INTRODUCTION This Shipping service is the life line of the people of Lakshadweep as they serve as the primary means for transportation of men and material in the mainland-island sector as well as in the inter-island sector. As a result of geographical isolation of these islands from main land, and from one island to one another, the people of these islands fully depend on the mainland for everything. In case of any disruption in the shipping services in the mainlandisland sector, the people immediately experience shortage of supplies of all goods like Public distribution system items, petroleum products, other items required for their day-to-day living in these islands. In addition to this for medical treatment the residents of Lakshadweep totally depend on the mainland. Shipping service is a critical component for the socio-economic development of the people and the islands as a whole, as this acts as the main link with the mainland and from one island to another. To meet the above prime requirement of the people of these islands, the Lakshadweep Administration has been operating ships/vessel between Kochi, Beypore and Mangalore Ports in mainland and islands. All the Public distribution system items, Petroleum products and other items are being transported from Beypore and Mangalore ports to these islands. At present Union Territory of Lakshadweep Administration is operating 7 passenger vessels, 3 high speed vessels and 4 cargo barges between Beypore ports and Lakshadweep islands for passenger and cargo movements. However, the Lakshadweep

1.1 Beypore Port – A Case Study The Existing Beypore Port is located on the south western coast of India (latitude 11˚08‟N & longitude 75˚51‟E), which is midway between the two major ports of Cochin and New Mangalore. It is situated at the mouth of Beypore/Chaliyar River which discharges to the Arabian Sea. Beypore was well known for its crafting of huge wooden boats called “Uru”. Boats built here were used on the sea routes to Arab countries. The area was also well known for spices and was a major stop on the old “Silk Route” to Mesopotamia. Kozhikode, a busy district town in Kerala is commercially well known to be an important trade centre for textiles, steel and timber products, seafood processing and tiles manufactures. Beypore has some port facilities in terms of berthing wharves where small vessels (mostly barges) operate. The traffic from mainland operates to and from Lakshadweep Islands through Beypore port. The traffic from Lakshadweep forms approximately 50% of the total of traffic through Beypore Port. The location of the proposed dedicated berth for
