Singapore-based shipbuilder Strategic Marine has signed shipbuilding contracts with Mainprize Offshore for two new 33 m Supa Swath crew transfer vessels (CTVs).

The new order increases the number of Supa Swath vessels delivered and ordered to Mainprize Offshore to 10.

Designed by Walker Marine Design, the new 33 m CTV builds on the 26m Supa Swath platform, upgrading it with an extended waterline length of 30 m, an expanded beam of 13 m, and an increased fuel oil capacity of over 63,800 litres, allowing for longer operational endurance.

Passenger capacity has also been increased to accommodate up to 39 people, up from 27 on the smaller design.

The vessel also features 360-degree visibility from the wheelhouse alongside a deck cargo area of 140 sq m with a load capacity of up to a class-leading 50 tonnes.

The two vessels are expected to be delivered in the third quarter of 2027. Upon completion, these vessels will expand Mainprize Offshore’s fleet to 21 vessels.
