Driving Decarbonization in the Workboat Sector

Unique collaboration on green fuels, new propulsion technology and hull-form optimization in the workboat sector will lay the foundation for global emissions reduction efforts.

The workboat sector, comprising one of the strongest categories of the UK’s Ship Register and including many Small to Medium size Enterprises (SMEs), is leading the charge in developing innovative technologies that will ultimately reduce emissions throughout the wider maritime industry. This is according to the Workboat Association (WA), the trade, skills and safety standards association, and naval architecture and marine engineering firm Chartwell Marine.

Continued momentum toward decarbonization in sectors such as offshore wind has driven widespread innovation in the maritime supply chain, as vessel designers and operators gear up to meet stringent emissions requirements and green targets for customers.

SMEs are particularly well placed to incubate new ideas and concepts to bring solutions to the market. Having launched a new Technical Working Group in 2019, which aims to accelerate the decarbonization of the workboat sector in line with the Clean Maritime Plan, the Workboat Association has hailed a number of significant milestones achieved by its members.

In recent months, members of this Technical Working Group have been responsible for a number of market firsts in the arena of vessel hybridization, alternative fuels and performance optimization, including:

•Offshore energy support vessel (OESV) operator Seacat Services is using a growing fleet of Chartwell 24 catamarans equipped with BAR Technologies’ foil optimized stability system (FOSS) to reduce fuel consumption and improve comfort for crew and passengers. Seacat has also placed an order for two BARTech 30 CTVs to further increase the versatility of its fleet and enable 30% emissions savings.

•John Spencer of GPS Marine Contractors, promoter of innovative cost-effective solutions with 50-years of service to the maritime industry, has converted one of his Tug vessels to run on Hydrogenated Vegetable Oil (HVO) and has purchased a tanker vessel ready to supply the Thames Marine community with HVO.

•Chartwell Marine has designed and brought to market several vessels with hull forms optimized for efficiency running hybrid diesel-electric drivetrains. Chartwell’s hybrid Chartwell 24 CTV design also won recognition for High Speed Transfers in Maritime U.K.’s innovation award.

•Manor Marine, shipbuilding and general marine engineering specialists, has built the hybrid Manor Endurance for Manor Renewables using a hybrid-electric onboard system.

•Leo Hambro of Tidal Transit, which provide access, transport and crew transfer services to the industries of the North Sea, has declared his intention to own and operate the world’s first fully electric CTV. Additionally, through Tidal Transit’s joint venture with Louis Dreyfus Armateurs and LD Tide, it is building two hydrogen ready, diesel electric hybrid CTVs for the growing French offshore wind industry.

•World Marine Offshore, provider of crew transfer services to the offshore sector, is building and operating hybrid cross-propulsion electric-diesel drive jet vessels.

•Windcat Workboats, owner of a 45+ fleet of offshore CTVs, is constructing the world’s first hydrogen driven CTV, which will be a dual fuel vessel and is expected for delivery in July 2021.

•CWind, an offshore wind crew transfer specialist, has announced the completion of CWind Pioneer, the first hybrid surface effect ship, which can reach speeds of 44 knots while delivering emissions savings.

Andy Page, managing director, Chartwell Marine, said, “The decarbonization of the maritime sector is now being spearheaded by small British and European businesses, particularly working in the offshore wind maritime supply chain. We have seen numerous experts in vessel design and construction collaborating through the Workboat Association’s Technical Working Group.

“By seizing the initiative on innovative naval technology, the skills and developments of the group can be scaled up and exported to support the global maritime industry in its continued drive to lower emissions.”

Kerrie Forster, CEO, The Workboat Association, added, “The members of The Workboat Association have made great progress towards decarbonizing the workboat sector. Our members are primed to deliver the innovation sorely needed by the offshore wind sector due to their agility as small companies. They have the necessary freedom to design and create technologies essential to reaching net-zero, pushing workboats into the spotlight of maritime decarbonization in the lead up to COP26.”

The Workboat Association sits on the U.K. government’s Clean Maritime Council, and is partnering with the Offshore Renewable Energy Catapult to deliver the road map for decarbonizing the North Sea Offshore Wind sector – now nearing completion following a recent week of industry workshops.
