Hybrid CTV on sea trials ahead of handover

Built at Isle of Wight shipyard Diverse Marine for High Speed Transfers, the HST Millie is IMO Tier 3 compliant with selective catalytic reduce to reduce NOx and SOx emissions.

“We are delighted to have HST Millie on sea trials, prior to her handover to High Speed Transfers,” said Ben Colman, director and co-founder of Diverse Marine.

“We have now safely lifted and installed the launch and recovery system on to the deck of the first production Hydronaut,” he added.

HST Millie’s unique hybrid propulsion system incorporates an electric motor alongside a diesel engine, which drives the changeable pitch propeller system.

At low speeds this allows for silent, zero emissions operation enabling the vessel to comply with port air quality requirements whilst retaining efficient operation at high speeds. The Chartwell Marine hull form with high bollard push and bow height ensures a confident transfer even in high seas, says Diverse Marine.

This is the third CTV for HST, after the successful delivery of sister vessels HST Ella and HST Frances.

“HST Ella was successfully delivered by Diverse Marine last year and she has proven to be highly capable, with the hybrid system exceeding our targets of reducing emissions and fuel consumption,” said Tom Nevin, chief executive, HST.
