Floating Offshore Wind Support Vessel

New concept supporting floating offshore wind installation

Enabling the next big development in offshore wind

Floating Offshore Wind Support Vessel

Damen Shipyards is developing a new class of vessel that will be capable of supporting the next big development in offshore wind, which is designed to be the installation of large scale, floating offshore wind turbines (FOWT). Forecasts indicate that by 2050 over 200GW of new FOWT will be in operation, equating to around 13,500 units, which together will be making a significant contribution to the transition to clean energy.

Reason to develop a new concept

The current market does not have an efficient vessel

Given the size of the turbines and the depths of the water in which they will be positioned, these FOWTs will require chains and anchors of unprecedented sizes. Even just one installation starting to drag an anchor could haveserious impact on the output of an entire wind farm. The anchoring systems must leave nothing to chance.

Concept principals

The need for more efficiency

While anchoring technologies will remain much the same, the vessels required will need to be much bigger than today’s anchor handling vessels. And given the projected demand for their services, they will also have to be exceptionally efficient.

Optimal efficiency

The vessel design is optimized for the most efficient installation method of the mooring chains and anchors. The laying method is faster than any existing vessel and allows for higher pull forces. Ample chain lockers and the extra-large deck area make it possible to carry an optimal payload of mooring so that the vessel can stay in the field much longer than any existing vessel.

Not just an anchor handler

While the efficient installation of chains, anchors and other mooring equipment is one of the main tasks, the vessel is also suitable for the tow out of floating offshore wind turbines.Adding to the versatility of the vessel and its operational capabilities are onboard accommodations units in combination with a motion compensated gangway. This enables service operations needed to further support the connection of the windfarm to the grid.

For a cleaner future

For renewable energy to be as clean as possible, it is also important that the whole chain supporting the energy production has the lowest emissions possible. That is why we have designed this vessel to operate on a dual fuel methanol system, in combination with a battery system, and modern power management systems.
