UK-based Seacat Services has ordered two more Chartwell 24 crew transfer vessels with Bar Technologies’ foil optimisation and stability system (FOSS)
The new deal closely follows Seacat’s order for an initial two vessels based on BAR Technologies’ BARTech 30 vessels in September 2020, with the build contract for all four boats awarded to Diverse Marine. Delivery of the vessels is scheduled for Q2 2022 and 2023.
The first two vessels with BAR Technologies’ FOSS, announced in September 2020, will be named Seacat Columbia and Seacat Cambria. The latter pair will be named Seacat Sceptre and Seacat Sovereign.
Seacat Services managing director Ian Baylis said, “The Chartwell 24 has already proven itself a versatile solution as we invest in our fleet to meet the demands of our broadening project portfolio. With the FOSS addition, Chartwell and BAR Technologies have helped us to take another step forward, while retaining the familiar vessel qualities that contribute to our proven formula.”
Chartwell Marine managing director Andy Page said that, with vessel operators now working in a wider range of sea conditions, the Chartwell 24 would provide the versatility they need.
Bar Technologies chief executive John Cooper said, “The offshore wind sector thrives on innovation, and the entrance of FOSS into the industry will continue to reduce costs.”
He said foil technology has been used for decades to reduce drag in high performance yacht racing. As highlighted previously by OWJ, the concept resembles a dynamic spoiler that sits below the waterline, increasing efficiency, enabling active roll and trim response to sea state without compromising speed.
Seacat’s first Chartwell 24, Seacat Weatherly – which does not have the FOSS – was delivered earlier in 2020 and sister vessel, Seacat Rainbow, was delivered in October. Both vessels are already at work at UK offshore wind sites.
