BMT 27m CTV hybrid design selected for European offshore wind energy

The latest evolution of the StratCat 27 CTV design, developed by BMT for Strategic Marine and HST Marine, features an industry-leading hull shape and integrates the latest hybrid propulsion technology.

BMT is pleased to announce that its 27m design has been selected by HST Marine, a Purus company, as one of its CTV vessel designs for the expanding European offshore wind market. Four hybrid StratCat 27 Crew Transfer Vessels (CTVs) built by Strategic Marine will be delivered in the first half of 2023. This quartet of deliveries will be the first parallel hybrid CTVs to be built in Asia.

The design resulted from a collaborative process between the BMT and Strategic Marine teams. Designed for optimal operational efficiency in a variety of load conditions with BMT’s proven hull shape, the CTV maximizes waterline length with a load line length under 24 m and helps reduce emissions and fuel consumption with a reliable fixed-pitch Cat C32 propulsion system. With a top speed of more than 26 knots, crews can transport technicians quickly and efficiently.

The ships are equipped with the latest generation of patented BMT Active Fender System ® (AFS) technology, which cushions contact with the turbine tower, thereby reducing shock loads on turbine structures, allowing ships to intervene in rough seas and ensuring safety in personnel transfers improved.

The cabin design has been optimized for improved comfort and workflow, with ample storage space, comfortable business class seating for 24 offshore service staff and accommodation for up to 9 crew members. To improve visibility from the helm station, the ship’s bridge deck layout has been improved with ergonomic positioning to increase comfort for the bridge crew. The parallel hybrid system, which reduces main engine operating hours and maintenance costs, can also significantly reduce ship noise and vibration. Depending on the ship’s operational profile and loading capabilities, the ship’s operational carbon footprint can be significantly reduced.

Martin Bissuel, Head of Commercial Ship Design Sales at BMT, said: “We are very proud to continue our collaboration with Strategic Marine, aligning our designs and support services alongside their growing list of new build CTVs. Our CTV offshore wind range, which currently includes more than 70 CTV designs already in service at wind farms worldwide, has been developed to meet the diverse and increasingly complex needs of the industry while reflecting our commitment to reducing the to meet the environmental impact of ships.

“With the global expansion of offshore wind power and the challenges of constructing and maintaining wind farms/CTVs in different locations, a flexible and forward-thinking mindset in design is required. I can’t wait for these boats to enter service with HST Marine,” added Bissuel.
