Delivering safe, sustainable & cost-efficient solutions

We are dedicated to delivering customized capacity to the rapidly growing offshore renewable sector.
We support the industry’s goals of increasing installed capacity, lowering the levelized cost of energy (LCOE), and minimizing emissions. Our subsea rock installation solutions are specifically designed to improve flexibility and cost efficiency for operations in and around bottom-fixed wind farms.

Introducing our new
SRI ships tailormade
to serve offshore wind

We have ordered two highly-efficient DP2 subsea rock installation vessels, each with an 17,500-tonne cargo capacity and capable of operating on MGO and/or methanol, providing a pathway to zero-emissions operations.

Purpose-built for optimal flexibility, these vessels will deliver efficient and cost-effective subsea rock installation services in water depths up to 100 meters. This includes the installation and maintenance of scour protection, cable burial, and other rock installation work related to wind farms.
