Diverse Marine & High Speed Transfers announce build of two further CTV’s on First Day of Seawork 2022

Diverse Marine and High Speed Transfers are proud to announce the contract signing of two further hybrid propulsion Chartwell Marine Ambitious Class CTV’s, following on from the success of ‘HST Ella’ delivered last summer.

The international expansion of the offshore wind sector is creating significant opportunities and challenges for the maritime supply chain and rewarding operators, builders and designers of innovative craft that meet legislative requirements, whilst reducing vessel emissions and fuel consumption.

These two new vessels, to be named ‘HST Frances’ and ‘HST Millie’ are developed sisters of ‘HST Ella’ that incorporate subtle changes following the operation of the vessel on multiple European projects over the last few months.

The catamaran’s unique hybrid propulsion system incorporates an electric motor alongside a diesel engine, which drives a high-performance changeable pitch propeller (CPP) system. At low speeds, such as port departure and arrival or whilst loitering in the wind farm zone, this allows for silent, zero emissions operation enabling the vessel to comply with port air quality requirements. At transit speeds, it can perform capably and efficiently while ensuring the comfort of technicians. The Chartwell Marine hull form with high bollard push and superior bow height ensures confident transfer at high wave heights.

Other features of the two new craft include enhanced foredeck capacity and wheelhouse visibility, which enables skippers, crews and technicians to safely navigate challenging logistical assignments. For HST, the vessels will support an ongoing commitment to the highest standards of service for offshore wind farms, while adding new levels and standards of efficiency, versatility and flexibility.

Ben Colman, Director of Diverse Marine said, “The maritime supply chain in the UK has had many challenges over the last few years but it continues to demonstrate that the UK is leading the way with innovations that will define the way vessels are built and operated worldwide. We are very proud of ‘HST Ella’, its innovation, its world class quality and the benefits and opportunities the craft provided us, our local Isle of Wight supply chain and how it demonstrated the very best of UK Shipbuilding capabilities. ‘HST Frances’ and ‘HST Millie’ further demonstrate the collaborative working of successful operator, builder and designer to produce environmentally friendly vessels and I am very proud of Diverse Marine’s relationship with HST and Chartwell as we deliver these vessels and the next generation of vessels that follow.”

Tom Nevin, Chief Executive Officer, HST added “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. We are very pleased to be working with both Diverse Marine and Chartwell Marine to deliver these two new vessels while we continue to work with the same team to define our next generation vessels.”

Andy Page, Managing Director, Chartwell Marine added “We are excited to be working with HST and Diverse Marine again to deliver these innovative hybrid CTV’s to market. As the drive towards greener operations gains momentum it is important that we tackle the emissions challenge head on, without losing sight of the key attributes that define effective offshore wind vessel support.”
