Seacat Services places four vessel order with Diverse Marine

24 November 2020

Order confirmed for two BAR Technologies designed BARTech 30 crew transfer vessels (CTV) and two Chartwell Marine designed Chartwell 24 crew transfer vessels with advanced Foil Optimised Stability System (FOSS).


Class-leading offshore energy support vessel (OESV) operator, Seacat Services, has ordered two further Chartwell 24 vessels to complement its growing fleet. This deal closely follows Seacat’s double order for the new BARTech 30 vessels, with the build contract for all four boats awarded to Diverse Marine. It strengthens the collaboration between the four South Coast-based businesses as they continue to bolster a robust local offshore energy supply chain. Delivery of the vessels is scheduled for the spring of 2022 and 2023. 


The BARTech 30 vessels - to be named Seacat Columbia and Seacat Cambria - are focused on creating fuel efficiency through a highly optimised SWATH PROA multi-hull design, working alongside BAR Technologies patented Foil Optimised Stability System (FOSS). These vessels will consequently be among the first true ‘Low Emission Vehicles’ (LEV’s) servicing the offshore wind market with total emissions 30% lower than conventional CTV designs as well as ultimately cutting CO2 emissions by up to 600 tonnes per annum if working on a 12 hour shift of operation.


These latest Chartwell 24 vessels - to be names Seacat Sceptre and Seacat Sovereign - will be the first equipped with a new Foil Optimisation Stability System (FOSS) designed by BAR Technologies. This system will enhance vessel stability, improving comfort for offshore wind technicians, and create substantial operational efficiency gains.


The addition of the FOSS to the Chartwell 24, will help dampen pitch and roll, further enhancing its seakeeping capabilities and manoeuvrability. This will ensure that technicians can be accommodated safely and comfortably for optimal job performance on arrival. Optimising the vessel in this way also contributes to reduced fuel burn and emissions, with efficiency savings of up to 15%.


Ben Colman, Diverse Marine: "We are delighted that Seacat Services have chosen Diverse Marine to build these innovative new vessels - testament to the strong links between these Isle of Wight companies and the quality of the workforce here at Diverse. Our relationship with Seacat and Chartwell goes back many years, whilst we are excited to integrate the new FOSS system into the proven Chartwell 24 design.”


Ian Baylis, Managing Director at Seacat Services said: “The Chartwell 24 platform 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.”


Andy Page, Naval Architect and Managing Director at Chartwell Marine, said: “Vessel design must take the needs of the end user into consideration. With operators now working in a wider variety of sea conditions, the Chartwell 24 range provides the versatility required to best serve the operator, whether that’s through hybrid propulsion variations or, in this case, the inclusion of FOSS technology.” 


John Cooper, CEO at BAR Technologies said: “The offshore wind sector thrives off innovation, and the entrance of FOSS into the CTV industry will continue to reduce costs in the maritime supply chain. Foil technology has been used for decades to reduce drag in high performance yacht racing, and now, we are proudly bringing the technology to the commercial sphere. A FOSS system resembles a dynamic spoiler that sits below the waterline, increasing efficiency, enabling an active roll and trim response to counter the sea state and provide class-leading stability – without compromising on speed.”


This announcement follows the launch of Seacat’s first Chartwell 24, Seacat Weatherly, earlier in the year and the delivery of sister vessel, Seacat Rainbow, in October. Both vessels were built by Diverse Marine and are already at work at UK offshore wind sites.

Diverse Marine’s Finance & Lease Programme Delivers Two CTVs, with Five More in Build

27 February 2025
Cowes, UK (27-02-25) Since launching its Finance & Lease Programme in November 2023, Diverse Marine has successfully delivered two crew transfer vessels (CTVs), with three more currently in build for delivery this year and two further shortly thereafter of the first batch.The programme continues to operate as a rolling initiative, providing new-build CTVs based on customer demand. The first vessel completed under the programme was NR Alpha, which was unveiled at Seawork last year. This Storm Class CTV has set new benchmarks for fuel efficiency and performance, leading NR Marine Services to order a third vessel—NR Rival, the first of the new Typhoon Class CTVs. NR Rival was delivered in January 2025. TheTyphoon Class features a hull form designed for exceptional head-sea performance and tower access while maintaining high buoyancy reserves for superior seakeeping in following and stern-quarter seas. It also comes with Zero Emissions (Power Management) class notation, recognising its efficiency in reducing fuel consumption and CO2 emissions. Stock Build 3, a first Brevity Class CTV is undergoing sea trials with the vessel available for quick delivery following rebrand to suit a prospective clients requirements. Stock Build 4, to be named NR Rebellion, a second Typhoon Class CTV, is now in its final build phase, with the wheelhouse and saloon fitted earlier this month. Again ordered by NR Marine Services, she is scheduled for launch and sea trials in March. Owen Nutt, Director at NR Marine Services, commented: “Receiving three world-class CTVs in the last 10 months has been transformative for our business. Each vessel has outperformed expectations in speed and efficiency, delivering significant fuel cost savings for our clients.This success has given us the confidence to order another Typhoon Class CTV and another Storm Class CTV through Diverse Marine’s Finance & Lease Programme, and we look forward to putting them to work soon.” Meanwhile, Stock Build 5, to be named NR Hunter, a third Storm Class CTV, is currently under construction at Diverse Marine’s facility in Cowes and will be launched at Seawork in June. Stock Build 6, an Ambitious Class CTV is also currently under construction and will be delivered to OEG, whilst Stock Build 7, a further Brevity Class CTV, will follow in Q3/Q4 of this year. Ben Colman, Director at Diverse Marine, added: “The success of our Finance & Lease Programme is proving that high-quality, next-generation CTVs can be more accessible and affordable for operators. By reducing the financial barriers to vessel ownership, we’re enabling companies to upgrade their fleets with more efficient and capable vessels.
