Green Marine (UK) has received Approval in Principle from RINA for their Project Verdant, which focuses on retrofitting crew transfer vessels (CTV) with hydrogen systems to reduce emissions while servicing offshore wind farms. The project, funded by Innovate UK, involves collaborating with maritime consultancy Waves Group and the European Marine Energy Centre (EMEC). The hybrid system design incorporates hydrogen fuel cells connected to electric motors and aims to reduce CO2 emissions by up to 30% and NOx emissions by up to 40%. The successful implementation of this initiative could pave the way for scaling up the production of zero-emission CTVs and service operation vessels (SOVs). The approach not only aims to enhance vessel redundancy and flexibility but also promotes environmental responsibility and decarbonization in the maritime sector. Jason Schofield, Managing Director of Green Marine (UK), highlights the potential for rapid replication of the concept, leveraging economies of scale and removing barriers to adoption. Jeremy Panes, Waves Group Engineering Director, emphasizes the achievement of a new standard for environmental responsibility in offshore services from both technical and commercial standpoints. This initiative represents a significant step towards advancing marine decarbonization and promoting sustainability in the offshore wind industry.
