Ulstein has developed a range of X-BOW vessels for the RoPax market. 

The portfolio is based on Ulstein's ‘compact concept’ of shorter, wider and slower design solutions, leading to high capacity vessels and less expensive newbuilds.

The X-BOW is one of Ulstein’s contributions to cleaner and more sustainable shipping operations. Introducing the X-BOW on RoPax vessels is a natural design development.

Many RoPax vessels operate in harsh areas, for which the X-BOW was originally designed. An X-BOW vessel at the same speed and weather conditions will use less power than a conventional bow vessel. The X-BOW hull line is a proven solution used in a number of different market segments, and leads to improved seakeeping, and reduced speed loss and fuel consumption, hence a reduced environmental footprint.

The seakeeping behavior of RoPax vessels is important to the integrity of the cargo and the comfort of the passengers. In many cases, the movements of a vessel call for a slow-down. This may in turn challenge the regular scheduling of a vessel. However, the X-BOW RoPax vessels will not need to slow down even in fairly rough weather, which help to keep schedules. This has been proven in offshore vessels, where more than 90 vessels are already in operation.

The ‘compact’ concept introduces higher flexibility with respect to vehicle logistics on board the vessels, a flexibility which is much appreciated by customers of the RoPax industry.

The propulsion system of the vessel can be designed according to the vessel’s operational profile and set schedule. A smaller propulsion plant will contribute to lower capital investments (CAPEX), less maintenance (OPEX) and reduced energy consumption (VOYEX), making the operation of the vessel more efficient.

Further, and equally important, power energy consumption improve the greener profile of the vessel and its operations.

The ULSTEIN ZED solution can also be used on RoPax vessels to achieve zero emissions for longer periods of time when at port or in environmentally sensitive waters.

Design of volume series has been carried out successfully in Ulstein several times, last seen with a series of up to ten expedition cruise vessels of which all will be built in China. With Norwegians and Chinese working side by side in our China-based companies, we can offer an understanding of both cultures which helps to smooth the language barriers and cultural challenges found in all walks of international business life.

The RoPax range have been developed for volume construction. For clients who request a higher degree of customization, Ulstein has their own prototype yard, Ulstein Verft, in Norway.
