Strategic Marine of Singapore has signed a significant contract with Mainprize Offshore for the construction of six 26m aluminium Supa Swath vessels, with an option for an additional six.
This agreement follows a Memorandum of Understanding (MoU) signed in June 2024 at Seawork, and the recent deliveries of MO10 and MO11, the latest additions to the Mainprize fleet earlier in the year. According to Strategic, this marks a strategic strengthening of fleet capabilities and service offerings.
The Supa Swath vessels, noted for stability, efficiency, and advanced technology, are designed to meet high standards of performance and versatility. The vessels’ stability makes them suited for demanding environments, while significant fuel savings thanks to low-emission propulsion systems contribute to sustainability goals. The latest navigation and communication technologies allow safe, efficient operations. Additionally, the design supports a wide range of maritime activities, including transportation, offshore support, and research.
Bob Mainprize, MD Mainprize Offshore, said: “We are thrilled to sign these contracts with Strategic Marine, which aligns with our vision of advancing maritime technology and expanding our operational capabilities with a reliable ship building partner. The Supa Swath vessels represent a significant investment in the future of our fleet, offering superior performance and versatility.”
Chan Eng Yew, CEO Strategic Marine, added: “This contract underscores the strong partnership between our companies. We are confident that the Supa Swath vessels will greatly enhance Mainprize Offshore’s fleet and contribute to their continued success in the offshore renewables industry.”
The first of the six Supa Swath vessels is expected to be delivered in Q1 2026, marking a significant milestone in the collaboration between Strategic Marine and Mainprize Offshore. This contract signifies Strategic Marine’s commitment to delivering innovative maritime solutions that meet the evolving needs of the offshore industry.
With the firm six vessel order, Mainprize Offshore would have effectively increased the fleet size to 17 strong by end 2026, with further potential to extend this figure to 21 by end 2028, placing the company in a good position to support the growing O&M requirements in the European region.
In addition to the earlier two Supa Swath vessels, namely MO10 and MO11, Strategic Marine can potentially offer a good track record of building these new ‘blank sheet of paper’ designs from UK-based Walker Marine Design.
James Walker, Naval Architect, Walker Marine Design, said: “It’s crazy to think this design started on a blank sheet of paper with Mainprize at a conference in Copenhagen in 2016. Eight years later there are eight Supa Swath’s in operation in Europe, two recently completed by Strategic Marine, started operations and more to follow soon.”
