Rolls-Royce Introduces Wave Piercing Technology to the Offshore Market

Posted on June 11, 2009

Wave piercing technology is a well-proven concept for high-speed catamarans and trimarans. Now, Rolls-Royce is bringing this design technology to the offshore market with the introduction of its next generation of offshore vessels in 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.

With wave piercing technology, the hull pierces through the water rather than riding on top of the waves, allowing the vessel to run continuously at service speeds regardless of the sea state reducing fuel consumption and improving crew comfort. This technology eliminates slamming and allows for a smooth ride even in extreme weather conditions, according to Rolls-Royce. At speeds of 14 knots and violent storm conditions (9 meter significant high waves), tank tests have shown no water above forecastle deck level.

The UT 790 CD vessel that was presented is a deep-water anchor-handling vessel. Anchor handling operations in deep water rely heavily on the vessel’s stability. A main aim in the design process has been to design an inherently stable vessel that also feels instinctively stable. 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.
