MARSEILLE, France Bourbon Subsea Services will manage the transportation and installation of a 3.6-MW floating wind turbine prototype, under a partnership with TetraSpar Demonstrator.

The scope covers project management, engineering, installation, and offshore execution from the assembly port in Denmark through hookup and the inter-array cable installation this summer on the Metcenter test site in Norway.

This is Bourbon Subsea Services fifth floating wind project.

The TetraSpar foundation concept is a modular, building block arrangement: each foundation is assembled from tubular steel modules, most of which are said to be common to all configurations.

Manufacturing is performed in factories using industrialized methods, with assembly near the site, and towing, taking days or weeks, instead of months.

Stability is provided by a keel deployed 50 m (164 ft) below the floater. Bourbon Subsea Services will use a special method to connect the keel to the floater in port and, once offshore, to lower it safely into position.
