We can develop 2 New Build 83.4m DP 2 PSV’s for Resale. The PX 121 PSV series are state of the art new vessels with high capacities and good station keeping capabilities.  The hull form, with the ULSTEIN X-BOW® and the diesel electric propulsion system ensures exceptional performances with regards to fuel consumption, sea keeping, station keeping, speed stability and cargo capacity. Built by an A-Class Chinese shipyard with Ulstein Design & Solutions providing a comprehensive design & equipment package that includes basic and detail design, all major equipment, site support, construction consultancy and commissioning.


This version of the medium-sized PX121 platform accommodates a total of 30 persons. The vessels have been prepared for an ROV mezzanine deck and a subsea crane for future installation. They will be built to DNV classification and in accordance to IMO’s SPS Code (Special Purpose Ships) for carrying specialised personnel, and will have OILREC class notation for oil recovery in emergency situations. The vessel is equipped with a dynamic positioning system IMO Class II.  They have a load capacity of approximately 4,000 tonnes and a cargo deck of 840 square metres. Maximum speed is stipulated to be 14.5 knots.  The vessels are suitable for worldwide operations.
