Diverse Marine and OEG Marine Services Sign Contract for Three Additional CTVs
Diverse Marine and OEG Marine Services are pleased to announce the signing of a contract for the construction of three additional crew transfer vessels (CTVs), with deliveries scheduled throughout 2027.
The three vessels will be built to Diverse Marine’s BREVITY SL Class design, developed by Southampton-based naval architects Chartwell Marine. Each vessel will have an overall length of 26 metres and a load line length of less than 24 metres.
The first vessel will feature quad Volvo Penta IPS propulsion, compliant with IMO Tier III emissions standards, alongside Hull Vane transom foils. This configuration has been optimised to enhance fuel efficiency at cruising speeds, with the aim of delivering industry-leading performance for vessels of this size.
All three vessels will be constructed to the same specification, classed by Bureau Veritas and operated under the UK flag.
The contract builds on the successful collaboration between the two companies, following the delivery of OEG Fulmar to OEG in 2025. The additional vessels will support OEG’s ongoing fleet renewal and expansion, strengthening its capacity to serve clients in the offshore wind sector from 2027 onwards.
Ben Colman, Director of Diverse Marine, said:
“Our team in Cowes takes great pride in the quality of the vessels we build and the solutions-focused approach we bring to every project.
“These new vessels will join OEG Fulmar, which we delivered to OEG in 2025. We look forward to continuing our relationship with OEG and delivering these larger craft.”
Leif Cooper, Director of OEG Marine Services, said:
“This contract marks OEG’s second collaboration with Diverse Marine, and we are pleased to continue working together as we progress our fleet renewal and expansion programme.
“The Chartwell design has performed above expectations, while the quality of the build from Diverse bears testament to our decision to continue the relationship with a further three vessels.
“These new vessels will help OEG continue to provide the best service to our clients in 2027 and beyond.”
Andy Page, Director of Chartwell Marine, said:
“It is great to see the BREVITY design continuing to develop through this latest collaboration between OEG and Diverse Marine.
“Innovative vessel design can improve operational efficiency, flexibility and safety in deep-water environments. With AR7 unlocking a new wave of vessel activity and investment, it is vital that we invest in UK supply chains to deliver the next generation of CTVs.
“We are proud to be working closely with both teams as these vessels progress towards entering service in offshore wind operations.”
