Windcat Crew Transfer Vessels

Partnership

Alewijnse has been working successfully for many years with offshore service provider Windcat Workboats and shipyards Dok en Scheepsbouw Woudsend and Neptune Shipyards. In total, Alewijnse has now delivered more than twenty Windcat vessels with electrical systems over a period of approximately eighteen years.

Offshore Crew Transfer Vessels

The offshore Crew Transfer Vessels (CTVs) Windcat 40 through 62 are part of a series of CTVs that owner Windcat Workboats had built at the shipyards Dok en Scheepsbouw Woudsend and Neptune Marine, with Alewijnse responsible for the electrical installation.

The Hydrocat is a special variant within the series because this vessel can operate on both diesel and hydrogen. Five of these vessels have now been built.

Windcat vessels

The vessels form part of a series of Windcat catamaran vessels, that are used to support the maintenance of offshore wind turbines by transporting technicians, equipment and special cargos to and from the sites. Windcat operates a fleet of over 40 small, fast catamarans of various models. They can be found at work primarily in the North, Irish and Baltic seas, in the waters of seven countries.

Complete installation

For the Windcat CTV's, Alewijnse is delivering the complete electrical installations including a console and alarm & monitoring system. A new feature for this series starting with Windcat 41 is the replacement of the conventional batteries with Lithium-Ion equivalents, due to their high energy density. Alewijnse is also assisting the yard in making and installing the aluminum cable trays and foundations.
