HST Marine takes delivery of the hybrid CTV

The British offshore crew transfer vessel operator HST Marine has taken delivery of the HST Ella, a hybrid crew transfer vessel (CTV).

The vessel, designed by the naval architects at Chartwell Marine, is the first Chartwell 24 hybrid vessel to hit the water, following completion at the local Diverse Marine shipyard on the Isle of Wight.

Tom Nevin, CEO of HST, said: “Rapidly maturing hybrid technology means environmental awareness can go hand in hand with operational excellence, and in HST Ella we have a ship that delivers both, following consultative design process with Chartwell Marine; and high quality construction at Diverse Marine.

The HST Ella offers transit speeds of 10 knots on electric propulsion and 30 knots on diesel, while during port operations the vessel’s electric operating mode allows for quiet, emission-free low-speed maneuverability, thanks to its hybrid propulsion system.

“An electric motor sits alongside a diesel engine to drive a high performance Variable Pitch Propeller (CPP) system, providing superior handling and operational flexibility. The system is coupled to the advanced hull shape of the vessel. for reduced frictional resistance, and its use of Hydrotreated Vegetable Oil (HVO30) as fuel – a market first for a new CTV, ”said HST.

According to the company, CTVs such as the HST Ella are increasingly called upon to perform a series of ancillary tasks alongside personnel transport.

The 26-meter vessel is capable of carrying 24 industrial personnel with a maximum payload of 15 tonnes. After launch, HST Ella will depart to begin its first contract on the East Anglia 1 offshore wind farm (EA1).
