Norwegian shipbuilder Ulstein Group has introduced a range of X-BOW vessels for the roll-on/roll-off passenger (RoPax) market.

The company leveraged its ‘compact concept’ to build the portfolio of shorter, wider and slower design solutions, aimed at offering improved capacity vessels and less expensive newbuilds.

Many RoPax vessels operate in harsh areas, which the X-BOW was originally designed for.

Contrary to the conventional bow vessel, Ulstein’s X-BOW vessel consumes less power even when it is operating at the same speed and weather conditions.

Additionally, new vessels do not need to slow down even in rough weather, which allows shipping companies to maintain schedules.

Ulstein said that the propulsion system can be designed considering the vessel’s operational profile and set schedule.

A smaller propulsion system requires lower capital investments, less maintenance and energy consumption to make the operation of the vessel more efficient.

To achieve zero emissions for a longer period, the RoPax vessels can be fitted with the Ulstein ZED solution, according to the shipbuilder.

Ulstein Design and Solutions COO Tore Ulstein said: “RoPax is a segment in growth, where we will see fleet renewals in the years to come. We have for some time worked to integrate Ulstein’s design mindset into a range of RoPax vessels.

“New vessels do not need to slow down even in rough weather, which allows shipping companies to maintain schedules.”

“These vessels are all equipped with the X-BOW hull feature, a natural choice when operating in climatically rough conditions.

“Our RoPax vessel designs are optimised according to market needs and will be constructed in series for the volume market. One potential country for the ship construction is China.”

Ulstein further said that the company will use its own prototype yard Ulstein Verft in Norway for clients seeking a higher degree of customisation for their ship.

In March, the company signed an agreement to build a polar vessel for Lindblad Expeditions Holdings.
