The X-BOW® hull line design is one of ULSTEIN's main contributions to marine history. The bow concept with the inverted bow was launched in 2005 and gained immediate interest from shipowners all over the world. Vessels with X-BOW® design are being built at shipyards on many continents, and close to 100 vessels (updated Q4 2014) with this innovative design concept are under construction or 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.
