Merchant ULSTEIN X-BOW® applications

The bow concept ULSTEIN X-BOW® was first launched in 2005. The revolutionary new design with the inverted bow gained immediate interest from leading shipowners, and has since demonstrated important benefits for offshore applications.

The ULSTEIN AX104 Bourbon Orca, the first vessel with the ULSTEIN X-BOW® , was appointed Ship of the Year 2006, and served to demonstrate how the Ulstein Group is turning visions into reality while also creating ship history.

However, the benefits of the bow are not restricted to offshore vessels, explains managing director in Ulstein Design Rolf Inge Roth. “The principle features of the ULSTEIN X-BOW® are as relevant for a number of merchant vessel applications as they have proven to be for offshore applications.”

The recent establishment of Ulstein Es-Cad provides for realizing such new applications. “By merging a track record within merchant and short sea shipping with the expertise and proprietary technologies of the Ulstein Group, we are now uniquely equipped for offering innovative ship designs for merchant and short sea shipping”, states Tore Ulstein, deputy CEO of the Ulstein Group.

Technical manager of Ulstein Es-Cad, Cem Aktüre, is heading the development of new concepts utilizing the ULSTEIN X-BOW® for merchant applications. “The features of ULSTEIN X-BOW® directly translate to enhanced profitability by increasing the earnings potential and reducing the operating costs of vessels, while also offering environmental advantages.”

Advantages of ULSTEIN X-BOW® :
• Higher transit speed in adverse weather conditions
• Reduced fuel consumption in head seas and following seas
• Reduced fuel consumption in ballast condition due to improved lightweight distribution
• Negligible slamming reducing the risk of damage to the vessel
• Lower pitch and heave accelerations, and enhanced protection of cargo areas reducing the risk of loss or damage of cargo
• Increased payload capacity for certain applications and configurations

“Particularly small and medium sized vessels engaged in regional trades are set to capitalize on the benefits offered by the ULSTEIN X-BOW® , and we are currently evaluating this feature for use on container feeder vessels, ro-ro vessels and certain general cargo vessels”, explains Cem Aktüre.

“For this purpose, we are working jointly with Ulstein Design for tailoring the ULSTEIN X-BOW® for these particular applications.”

Ulstein Es-Cad was established in December last year by the Ulstein Group, Norway, and the ship design company Es-Cad, Turkey. Ulstein Es-Cad can perform engineering work for Ulstein Design and yards that the Ulstein Group sells designs to.
