Five stages in the lifecycle of an offshore wind farm.

Ship designs worldwide

When designing a ship, Ulstein helps shape the maritime industry. By providing sustainable and efficient solutions, we do our part to create a highly competitive and green business. The connection between operational challenges, the use of new technology, and commercial solutions is high on our priority list.

Pioneering tomorrow

Our approach to design is always to seek solutions to new challenges. A new design is an opportunity to improve our previous work. We use our expertise and imagination to provide the industry with new standards based on long-term competitiveness. We can do this by designing with a focus on the environment, cost-efficiency, reliability and the total life cycle cost of the product.
