POWER & PROPULSION
NEOLINE OPTS FOR SOLID SAIL TECHNOLOGY The Solid Sail solution from Chantiers de l’Atlantique has been chosen to power NEOLINE’s new vessel Nantes-based, low-carbon shipping company NEOLINE will power its 136-metre ship, Neoliner, with the sail technology, which will save 80-90% of fuel compared to a conventional ship of the same size. ”The expertise of our technical partners and local players, combined with Chantiers de l’Atlantique’s Research and Development, give the project a synergy of skills, which made this choice possible,” said Jean Zanuttini, president of NEOLINE. ”The continuous work on the general design of the ship over the last few months by Mauric, Neoliner’s architect, has enabled the architecture to be adapted to this new rig, in order to ensure its integration on board.” Crowdfunded Following technical studies carried out by Chantiers de l’Atlantique, Neopolia, Mauric and D-Ice, the ship’s rigging will consist of two Solid Sail folding rigging systems, including two masts of 76 m in height, each equipped with the sail technology of 1,100 m² and a flexible jib of 400 m², with a total sail area of 3,000 m². Obtained calculations show that the Solid Sail rig will provide the equivalent or even better performance than the 4,200 m² of flexible sails initially planned for the duplex rig, thanks to the thinness and vertical elongation of the structure, as well as the reduction of the masking effect of the sails. The expected lifetime of the sail is 25 years, which will reduce maintenance costs compared to soft sails. A crowdfunding campaign was launched in January 2022 to support the project and will remain active until 12 June 2022 on the WiSEED platform. In all €1million is sought for the crowdfunder, which forms part of the fundraising of €3.3million from financial investors. The beginning of construction of Neoliner has been
postponed to autumn 2022. This is due to the interruption of international trade, with the raw materials market being impacted by the geopolitical situation and the war in Ukraine since the beginning of March, and before that, the global pandemic. For strategic reasons, the Sogestran group has decided to withdraw from NEOLINE’s shareholding and has provided transitional financial support for the integration of a new reference partner. NEOLINE has approached another shipowner with whom discussions are in progress. The cargo ship is scheduled to enter into service in 2024-2025.
8 NEOLINE will power its 136-metre Neoliner with Solid Sail technology
Cutting-edge fuel vessel supply MAN will supply fuel-gas supply systems (FGSSs) to a new series of two dual-fuel car carriers. MAN Cryo signed the contract with Yantai CIMC Raffles Shipyard for the delivery of systems that will be fitted to the Wallenius Marine 6,500 pure car carriers going on charter to Volkswagen. “This represents yet another world-first for MAN Cryo, where the boil-off gas will be sent to the low methane-slip ME-GI via a highpressure, boil-off-gas compressor. Due to the installed shaft generator, this further reduces the running hours on the auxiliary engines,” said Henrik Malm, managing director at MAN Energy Solutions, Sweden and Finland.

The MAN FGSS will send boil-off gas to the ME-GI main engine via a BOG compressor, which minimises methane slip. Scope of delivery includes port and starboard-side bunkering stations, a 2,300 m3 LNG storage tank, tank connection space with low-pressure vaporiser, BOG heater and two LNG pumps and high-pressure gas-handling equipment. MAN Cryo willl also supply a boil-off gas management system, including one highpressure compressor, on-board nitrogengeneration system and the control system as well as gas-detection system. The FGSSs for the vessels will be delivered during 2023.
