TWD has marked the first anniversary of Boreas by highlighting its role in designing monopile deck equipment for the offshore installation vessel.

The Dutch engineering company worked with Van Oord on the vessel’s monopile deck spread, which supports the transport, securing and installation of large monopile foundations for offshore wind projects.

The scope included a four-lane monopile seafastening system, an upend hinge system and a monopile gripper with integrated noise mitigation deployment technology.

The design was developed as offshore wind foundations continue to increase in size and weight. For installation vessels, that trend places more pressure on deck layout, cargo securing systems and operational flexibility.

According to TWD, the seafastening arrangement was engineered to handle a wide range of monopile diameters. This allows Boreas to support different project requirements without major equipment changes.

The engineering work also covered structural integration and load spreading. These elements help manage the forces created by heavy monopile cargoes and support safe handling during transport and installation.

The monopile handling equipment was also integrated with the vessel’s wind turbine generator deck spread. For offshore contractors, this can help reduce mobilisation time between project scopes and improve vessel use.

Boreas was developed for large offshore wind installation work and is part of the growing fleet of specialized vessels serving the renewable energy sector. Its first anniversary comes as offshore wind developers and contractors continue to expand capacity in Europe and other markets.

For TWD and Van Oord, the anniversary underlines a partnership focused on equipment design for larger and more complex offshore wind installation campaigns.
