Houston-headquartered Friede & Goldman Ltd. (F&G), continues to draw on its 72 years of offshore industry experience to develop Jones Act solutions for offshore wind turbine installation.

Following up on its earlier announcement of its NewWindShape system, F&G has now announced BargeRack.

Suitable for the installation of turbines of up to 20 MW, the solution eliminates motions between the self-elevating installation vessel and the feeder vessel and thus the need for motion-compensation equipment.

BargeRack utilizes a trussed rack fitted to the transom of a relatively small self-elevating vessel. The feeder barge, with its turbine component cargo, is floated over the submerged rack. Once the feeder barge is secured, the self-elevating vessel uses its onboard jacking system to elevate, while also lifting the feeder barge completely out of the water.

From this position, the main crane installs the wind turbine components directly from the stationary feeder barge onto the turbine foundation. After turbine installation, the self-elevating unit jacks down into the water, submerging the rack, and re-floating the now empty feeder barge.
