Chartwell, Diverse to build hybrid CTV for High Speed Transfers


Chartwell Marine, a pioneer in next-generation vessel design, has signed a contract to design and deliver a new hybrid Chartwell 24 crew transfer vessel (CTV) for High Speed Transfers (HST), an innovative CTV operator that supports the offshore wind energy and oil and gas industries worldwide. The vessel, which will provide dedicated support for the offshore wind sector, is set to be built locally in the U.K. by Isle of Wight yard Diverse Marine, which was awarded the build contract following a competitive global tender process.

HST’s order marks a milestone in the collaboration between these three British firms, which has seen a number of adaptations made to the proven Chartwell 24 design to meet the demands of hybrid operation.

The international expansion of the offshore wind sector is creating significant opportunities for the maritime supply chain and simultaneously driving substantial innovation in vessel design as operators respond to new and emerging legislative requirements. 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.
