Huisman has modified its existing gripper design to meet Subsea7's requirement to maximise the vessel payload. For this new design, Huisman applied the proven technology of its existing range of Grippers. This has resulted in a lightweight, robust and very stiff Monopile Gripper, capable of handling XXL monopiles.

Huisman has paid special attention to optimising the upending process. The Monopile Upending Frame is adjustable in length and, therefore, suitable for handling a wide range of monopiles.

The Monopile Storage Cradles are outfitted with adjustable saddles to be able to store various monopiles sizes. The cradles can be expanded with an additional layer to double the vessel's storage capacity.

Since the Seaway Ventus will be deployed for monopile as well as wind turbine installation, Huisman has taken into account easy and quick (de)mobilisation of the monopile installation spread. The equipment will be integrated in the vessel in such a way that the permanently installed parts are kept to a minimum, further maximising the payload.

The monopile installation spread will be engineered, built, and installed on the Ventus at Huisman's premises in Schiedam, the Netherlands.

David Roodenburg, CEO of Huisman said: "We are grateful to Seaway7 for trusting us to equip their vessel with the entire installation spread. This is where we add value, supplying integrated lifting equipment that increases safety, efficiency and workability. After building a long track record of Pipelay Systems with Seaway7's parent company Subsea7, this order marks our first contract with the group for wind installation equipment. We are extremely excited to join them in their ambition to lead the way in the delivery of fixed offshore wind projects and contributing to an efficient and sustainable energy supply for the future."
