New Wave Piercing Design for Offshore

In at Norshipping 2009 Roll-Royce debuted an innovative wave piercing design for the offshore market, the new UT 790 CD vessel design. “With the UT 790 CD, we can support offshore exploration and production further and deeper while at the same time improving safety and minimizing the impact on the environment,” said Svein Kleven, Rolls-Royce Chief Design Manager – Offshore.

The unique hull piercing design is designed to allow the vessel to run continuously at service speeds regardless of the sea state reducing fuel consumption and improving crew comfort.

This technology reportedly eliminates slamming and allows for a smooth ride even in extreme weather conditions. At speeds of 14 knots and violent storm conditions (9 m significant high waves), tank tests have shown no water above forecastle deck level.

The UT 790 CD vessel presented in is a deep-water anchor-handling vessel. The vessel meets all existing regulations from the Norwegian Maritime Directorate and all latest international regulations such as SOLAS2009 and Special Purpose Vessel codes and regulations.
