Offshore wind references

Ulstein is well established in the Offshore Wind maritime industry. We have developed several vessels in this segment, including installation or decommissioning vessels for offshore wind farms (OWF) and Service Operation Vessels, and, additionally, several products for lifting and handling of wind equipment.
