The X-BOW® hull line design is one of ULSTEIN's main contributions to marine history. The bow concept X-BOW® was launched in 2005. The revolutionary hull line design with the inverted bow gained immediate interest from shipowners all over the world. Vessels with X-BOW® design are being built at shipyards on many continents, and more than fifty vessels (updated Q1 2014) with this innovative design concept are in operation around the world.
Power efficiency: The bow shape reduces pitch/heave accelerations and speed loss in waves, which renders higher transit speed or reduced power consumption possible. This improves fuel efficiency and reduces emissions to air.
Comfort: The bow shape eliminates slamming and bow impact, thereby reducing noise and vibration. This leads to a more comfortable workplace and more effective rest time for the crew.
Safety: The bow shape gives a soft entry in waves, thus reducing spray and icing. The likelihood of extreme weather damage to the forebody is reduced.
The X-BOW® hull line design is patented in Norway (reg. no. 324744), Russia (reg. no. 2374120), Singapore (reg. no. 135279 (WO/2006/096066)), Ukraine (reg. no. 95070), USA (reg. no. 7,658,159) and Vietnam (reg. no. 8437). Patent is pending in Brazil, China, Europe (EPA), Hong Kong and India.
