Ulstein designed PSVs

Tore Ulstein, deputy CEO, Ulstein Group, said: “We are happy to see the materialisation of this project and that the yard and the owner, who, after careful evaluation of different designs and design companies, in the end selected Ulstein as their partner when entering into the offshore market.”

When completed, the ships will have a length of 83.4m and a beam of 18m and meet the requirements of DNV’s Clean Design notation. They will have a load capacity of approximately 4,000 tonnes and a cargo deck of 840m². Maximum speed will be stipulated to 14.5 knots.

Ulstein’s X-bow inverted bow helps reduce speed loss in stormy weather which means less fuel consumption. Less slamming is also an attractive feature for crew comfort. ROC is a new yard entering into constructing vessels carrying the unique X-bow hull line design from Ulstein.

This version of the medium-sized PX121 platform will accommodate 30 people. The vessels will be prepared for an ROV mezzanine deck and a subsea crane for future installation. They will be built in accordance to IMO’s Special Purpose Ship (SPS Code) for carrying specialised personnel, and will have OILREC class notation for oil recovery in emergency situations.

The vessels are planned for delivery in the first half of 2015.
