Developed off the back of ten years of data and experience in offshore wind vessel design, alongside extensive dialogue and collaboration with wind farm owners and turbine manufacturers, the Purus HST Hybrid Chartwell 24 responds directly to the needs of the end user. The vessel hits a “sweet spot” in size and capability that has been achieved by the most effective vessels currently operating in the offshore wind market.
The Purus HST Hybrid Chartwell 24 is propelled by a Servogear Ecoflow Propulsor, controllable pitch propeller system. The CPP system takes power from either a high efficiency electric motor or a CAT C32 main engine. This means the Purus HST Hybrid Chartwell 24 has the capability to operate silently, with zero emissions, as an electric boat at speed between 10 and 15 knots. Further, when operating as a diesel boat at transit speeds the boat is capable of operating efficiently and comfortably at speeds in excess of 25 knots.
Once at the offshore wind turbine or offshore substructure, the Purus HST Hybrid Chartwell 24 is capable of delivering 19T bollard push. Coupled with the advanced hull form and superior bow height of the Purus HST Hybrid Chartwell 24 this will allow the vessel to transfer comfortably in seas in excess of 1.75m HS.
