Following the trails of the X-BOW® and the X-STERN®, the TWIN X-STERN™ is yet another innovative design for improved operability and fuel efficiency. This design has many characteristics, but what makes it stand out from the crowd lies somewhere below the waterline.


How to get a competitive edge

Standards and demands for efficiency, safety and green responsibility are changing, and marine operations are becoming more and more complex. To keep pace under such conditions can be demanding.

The TWIN X-STERN has several characteristics, but the easiest way to describe it is as a ship with two sterns and four main propeller units: two at each end.

This concept dramatically improves the manoeuvrability, movement and ability to stay in position for the vessel. Qualities that make the TWIN X-STERN ideal for wind farm operations. Further, the concept allows for reduced noise, more comfort on board and the potential to save significant amounts of energy in operation.

By having excellent performance in either direction, you avoid having to turn the ship to follow weather changes Lars Ståle Skoge, Commercial Director at Ulstein Design & Solutions

“By having excellent performance in either direction, you avoid having to turn the ship to follow weather changes. This is traditionally required up to 50 per cent of the time, depending on the operation being performed,” says Lars Ståle Skoge, Commercial Director at Ulstein Design & Solutions.

It's a win-wind situation

As a shipowner or operator, there is a need to think about the lowest possible life cycle cost in the fleet. Cost-effectiveness related to fuel consumption has always been a concern for the shipowner, but there is also a growing concern with respect to the environmental consequences. The commitment to achieve zero-emission marine operations by 2050 sets a new standard. Older vessels need to be upgraded and new vessels need to be designed with a more sustainable approach in mind.

To be able to deliver on emission goals is becoming a larger criterion when contracts for wind farm operations are tendered. The TWIN X-STERN might be the competitive edge you need as an operator to win market shares in the offshore wind industry and take a sustainable responsibility. It's a win-wind situation.

Sustainable innovations

The X-BOW was invented back in 2004 and was later leveraged with the introduction of the X-STERN, both of which have enjoyed great market success. The TWIN X-STERN was introduced in 2015 and is now market-ready, available on a range of vessels, including vessels servicing offshore wind turbines.
