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.

NR Marine Services commissions Chartwell Marine to bring a new legacy turbine vessel to the market

11 June 2025
Southampton, 17th June 2025 — NR Marine Services is excited to announce that it has commissioned Chartwell Marine, a trusted pioneer of next-generation vessel design, to design a new CTV in response to client requests for a new class of vessel that is capable of supporting older generation assets, now referred to as legacy turbines, but utilising modern construction and outfit technology to maximise vessel fuel efficiency and technician comfort. It has been a generation since UK based Naval Architects and Shipyards designed a sub 22m, sub 60 tonne, sub 3m bow height crew transfer vessel. Chartwell Marine has developed the ‘Defiant Class”, a 20m CTV designed to Workboat Code Edition 3 with IMO Tier 3 compliance featuring a step free flush forward deck, resiliently mounted superstructure and modern furnishings and materials used in larger CTVs. This is a bold, DEFIANT step to do different, to create a new class of smaller CTV required for legacy turbines whilst not losing the core identity of modern UK designed, UK built and UK operated CTVs. DEFIANT in compliance, this new class of CTV will comply with Workboat Code Edition 3, IMO Tier 3 and the spirit and core fundamentals of HS_OSC – albeit in a more cost-effective approach. DEFIANT in pricing, it is essential the new class is cost effective in the modern market. UK quality but smartly sized to benefit from UK supply chain core strengths and therefore pricing. DEFIANT in reliability, working with supply chain to integrate a new, smaller Quad IPS IMO Tier 3 or Hamilton Waterjet propulsion solution with high power to weight ratio whilst maintaining simple, quality and reliable engineering. DEFIANT in change, accepting most legacy turbines have unique site requirements, the vessel retains flexibility to be tailored to different projects from a water jet propulsion system for shallow water sites and hybrid options where budgets allow to internal modularity to suit different racking and seating solutions. Andy Page of Chartwell Marine Ltd. said: “It is always enjoyable bringing a new class of vessel to the market. What’s interesting in this case, is the vessel is based-on “legacy vessel” parameters but with modern up-to-date experienced thinking. With the Defiant Class, we are able to utilise our proven high efficiency, high seakeeping performance hull form, in a smaller, more dynamic cost-effective platform, appropriate for the legacy turbine projects the vessels are intended to support”. Richard Thurlow of NR Marine Services Ltd. adds: “NR Marine Services is excited to be the first to bring the brand-new Chartwell DEFIANT Class CTV to the market. With strong industry focus being on the HSOSC market space, the CTV development has been taken away from the smaller vessel market. Working closely with Chartwell Marine and Diverse Marine we have looked at incorporating as many of the recent CTV developments a possible into a smaller package. Step free access from deck level to bow step over point, tiered seating, Male and Female heads, comprehensive galley suite and optimised hull design for near shore projects. Following an internal fleet review long with external market research, the data shows that there is a potential to replace older tonnage which is between 10-15 years old for near shore projects which have a lifespan that warrants investment in new CTV’s”. Ben Colman of Diverse Marine Ltd. adds: “Many years ago, the UK proved that building large numbers of smaller CTV’s was possible but these times have been forgotten as the CTV industry as evolved into larger. HS-OSC compliant craft. It is both exciting and challenging to be involved a project to build a new smaller CTV that meets the growing demand for legacy turbine access with modern technological compliance, modern materials, high fuel efficiency, hybrid options. Put simply the Defiant hosts, a modern, clean and spacious environment but on a smaller highly efficient platform that suits the smaller harbours, short transit sites and shallow water projects."
