Offshore wind references

We are well established in the Offshore Wind industry with ship designs for all stages of an offshore wind farm including installation and decommissioning, cable lay & pipe pay, and service operation vessels. We have built numerous offshore wind vessels at our yard, and have followed up the construction at other yards.
