Strategic Marine, a prominent Singapore-based shipbuilder, has secured a significant contract with Mainprize Offshore for the construction of two 33-metre Supa Swath crew transfer vessels (CTVs). This order, announced on 19 May 2026, marks the third such collaboration between the two companies, bringing the total number of Supa Swath vessels delivered and on order to 10.
The new vessels, designed by Walker Marine Design, are an upgrade from the previous 26-metre model. They feature an extended waterline length of 30 metres, a broader 13-metre beam, and increased fuel capacity exceeding 63,800 litres. These enhancements allow for longer operational endurance and increased passenger capacity, accommodating up to 39 personnel compared to the previous 27.
Bob Mainprize, Managing Director of Mainprize Offshore, expressed confidence in the partnership, stating, “The Supa Swath design continues to perform well in the field, especially in terms of stability, safety and crew comfort, which are critical to our operations.” The vessels are powered by two Caterpillar C32B engines, enabling speeds of up to 30 knots whilst maintaining fuel efficiency and reducing emissions.
Strategic Marine’s CEO, Chan Eng Yew, highlighted the significance of the order as an endorsement of their capability to meet evolving offshore operational needs. The first two units are scheduled for delivery in Q3 2027, expanding Mainprize Offshore’s fleet to 21 vessels, supporting offshore wind operations across Europe and Asia.
