Green light for Green Marine’s hydrogen CTV

Led by Orkney-based Green Marine, Project Verdant is aiming to decarbonise the CTVs that ferry personnel to and from offshore wind farms. Phase 1 of the project saw the team design a hydrogen-diesel hybrid vessel capable of operating with zero emissions at low speeds, for example when loitering near the base of a turbine. Findings show the hybrid system could reduce the vessel’s CO2 emissions by up to 30 per cent and NOx emissions by up to 40 per cent. 

The design has now been granted Approval in Principle (AiP) by Italian classification society RINA. The AiP paves the way for subsequent project phases of design, engineering and sea trials.

“With technical feedback supplied by RINA we now have all the necessary input to progress to the detailed design and implementation phase.,” said Jason Schofield, managing director at Green Marine UK.
