UK engineering consultancy and ship designer Longitude Engineering has been selected to support a consortium led by vessel owner and operator Bibby Marine for the design of a zero-emission electric Service Operation Vessel (eSOV), which will operate in the UK and European offshore renewables markets.
The vessel project has been awarded £20m in UK government funding under the Zero Emission Vessel and Infrastructure (ZEVI) competition. The ZEVI project aims to accelerate the development of clean maritime solutions, and specifically of battery electric vessels and charging infrastructure. Having developed the concept for the consortium, Longitude is developing the design to Approval in Principle level for verification of the energy storage system and methanol system philosophy. This phase includes design development and support for shipyard pricing.
Dean Goves, Maritime Design Director, Longitude Engineering said: “Whilst development of our renewable energy infrastructure increases, decarbonising the wider project value chain is also of critical importance to further move the dial on our race to net zero. Studies have been conducted to explore the carbon footprint of marine operations in offshore wind construction. This project is the next step – engineering a solution. It has the opportunity to set the tone for future enhanced decarbonisation of vessels involved in offshore operations.”
The eSOV is based on Longitude Engineering’s OSD-IMT9605 design. The vessel will be powered by a hybrid 20MWh battery system and dual-fuel methanol generators for back-up and offshore charging capability. The vessel will provide ultra-low emission support to offshore construction, operations and maintenance activities in the offshore renewables sector in the UK and elsewhere in Europe, in particular supporting Europe’s growing offshore wind market.
Nigel Quinn, Bibby Marine CEO added: “As we announced back in September, we are building the world’s first eSOV. This project is the natural progression of our decarbonisation journey, as we aim to operate a low or no carbon emission vessel by 2026. Designed in the UK, the vessel will be a game-changer for our industry, and we are delighted to work alongside some of the market leading contractors and suppliers on this project, such as Longitude. Longitude’s expertise in specialised vessel design is vital to us realising our net-zero goals and getting our eSOV in the water.”
Longitude will apply a multi-disciplined engineering and marine consultancy team to work on this project, including naval architects, master mariners, electrical engineers, specialists in methanol and energy storage solutions, structural engineering, hydrodynamics, and marine engineering. Longitude Engineering has specialised vessel design expertise with a track-record of over 100 vessels constructed to its designs across a range of marine sectors. The company’s expertise was enhanced in 2021 through the acquisition of ship design bureau OSD-IMT. The company is part of Oslo-listed, global energy and marine consultancy group ABL Group ASA.
The consortium behind the eSOV is made up of Port of Aberdeen, ORE Catapult, Kongsberg, DNV, Shell and Liverpool John Moores University, as well as Bibby Marine.
