Technology: Rolls-Royce Debuts New UT Designs

Rolls-Royce introduced a pair of new vessels for its popular UT line of vessels, the UT712 and the UT737L.

Under development for almost three years, according to Svein Kleven, Rolls-Royce Marine AS, the design is an evolution of the UT745E, and is particularly notable that it demanded classification society Det Norske Veritas to create a new classification for the type: Ship Shape Well Intervention Unit 1.

Small Tankers, Huge Market Potential

Rolls-Royce has introduced an innovative "pulling tanker" design to fill a need in the small (3,000 to 16,000 dwt) tanker niche, a niche which the company suspects will have to be filled with 1,000 vessels worldwide in the coming five years. In fact, there are strong indications that an order from a not yet-named owner is coming soon, possibly announced before or during this year's Nor-Shipping event in Oslo in early June, according to company officials. The heart of the concept — which was started about 1.5 years ago, as pressure mounted on owners in the wake of Erika — are twin Ulstein Aquamaster Azipull thrusters with pulling propellers…
