Wind Energy – DNV Approval

An innovative wind turbine installation vessel (WTIV) design from Houston-based naval architecture and marine engineering firm Friede & Goldman (F&G) has earned approval in principle from classification society DNV.

The review and AIP confirms that F&G’s Windsetter 156 Class WTIV with optional BargeRack feeder barge system design complies with applicable DNV classification rules and statutory requirements.

The WTIV design is suitable for all offshore wind markets globally and was developed in conjunction with wind equipment vendors and feeder logistic companies with the capability of installing turbines with more than 20 megawatts (MW) of capacity.

The F&G WTIV design is unique to the market, as the vessel is equipped with F&G’s optional BargeRack feeder barge system enabling Jones Act-compliant operations in the U.S. Meanwhile, the BargeRack is removable, allowing the vessel to assume traditional WTIV operations in other markets globally.

The AIP review involved assessing the overall feasibility of a vessel’s design, given the level of detail presented in the documents included in the review. For project stakeholders, a successful issuance of an AIP provides confidence that no showstoppers exist with the design that may prevent future classification.
