Green propulsion collaboration announced

Seawork 11th - 13th June 2024	Speed@Seawork 10th June 2024	Commercial Marine Network Conferences

The 25th edition of Europe’s largest commercial marine and workboat exhibition, provides businesses the opportunity to showcase their services, equipment, vessels and supplies to an international audience.	Speed@Seawork on Monday 10 June in Cowes offers a sector specific event that showcases fast vessels operating at high speed for security interventions and Search & Rescue.	The Commercial Marine Network, in partnership with Seawork and Maritime Journal, introduce Series 3 of ‘Get set for Workboat 2050’. An online conference series of expert panels navigating the waters of decarbonisation compliance and looking at practical applications across the workboat industry.

At SMM 2018, three of the marine sector’s major technology companies have announced a collaboration around increasing the viability LNG propulsion.

WinGD, Wärtsilä and GTT, by combining their expertise and experience, plan to deliver an effective, streamlined approach for achieving compliance with environmental legislation.

LNG fuel is considered a key enabler of ‘green’ propulsion for ships. It has virtually no sulphur content, produces 80 percent less nitrogen oxide (NOx) and 30 percent less CO2 emissions than conventional marine fuels, and is competitively priced. With LNG being more widely available and accessible, it is now a feasible green fuel option.

In 2017, a notable advance in the acceptance of LNG as a marine fuel was recorded with an order by CMA CGM for nine ‘mega’ containerships, each with a record capacity of 22,000 TEU, to be built with LNG fuelled engines. These will be the first vessels of this type and size to operate on LNG. WinGD, Wärtsilä, and GTT cooperated closely in providing the required equipment for these vessels, and it was through this shared expertise that the industry-shaping collaboration was born.

GTT (Gaztransport & Technigaz) is an engineering company expert in containment systems with cryogenic membranes used to transport and store liquefied gas, in particular LNG (Liquefied Natural Gas). For over 50 years, GTT has been maintaining reliable relationships with all stakeholders of the gas industry (shipyards, shipowners, gas companies, terminal operators, classification societies). The company designs and provides technologies which combine operational efficiency and safety, to equip LNG carriers, floating terminals, and multi-gas carriers. GTT also develops solutions dedicated to land storage and to the use of LNG as fuel for the vessel propulsion, as well as a full range of services.

WinGD is a leading developer of two-stroke gas and diesel engines for marine propulsion. Headquartered in Switzerland since its inception as the Sulzer Diesel Engine business in 1893, it carries the legacy of excellence in design. With worldwide offices, research and training centres, WinGD employees represent over 25 different nationalities.
