The CTV operator High Speed Transfers (HST), supporting the offshore wind energy and oil and gas industries worldwide, is to take delivery of Chartwell’s new hybrid Chartwell 24 CTV (crew transfer vessel) to be built by Diverse Marine at the company’s Isle of Wight UK yard.

Reducing vessel emissions and fuel consumption is a key target for the industry to ensure compliance with air quality legislation and reduce the overall carbon footprint of building and operating offshore wind farms.

The Chartwell 24 catamaran’s unique hybrid propulsion system incorporates an electric motor alongside a diesel engine, which drive a high-performance changeable pitch propeller (CPP) system. At low speeds, this allows for silent, zero emissions operation, enabling the vessel to comply with port air quality requirements. At transit speeds, it is able to perform capably and efficiently while ensuring the comfort of technicians. Its advanced hull form, high bollard push and superior bow height ensures confident transfers at high wave heights.

For HST, the vessel will support an ongoing commitment to the highest standards of service for offshore wind firms, while adding new levels of efficiency, versatility and flexibility.

Tom Nevin, Chief Executive Officer, HST, said: “As our partnerships grow throughout new markets, we need to continue investing in our fleet in order to address unique demands, opportunities and emerging requirements. With the addition of this highly capable hybrid vessel, we’re confident that we can continue supporting technical innovation in important areas like emissions reduction, while adding significant value for our customers.”
