Seaplace receives LR AIP for Ballast Control System

LR has granted Seaplace Approval in Principle for its active ballast control system, designed specifically for the company’s floating offshore wind

LR has granted Seaplace Approval in Principle for its active ballast control system, designed specifically for the company’s floating offshore wind platforms concept, CROWN, a novel technology that includes both buoy and reduced-draft spar operational concepts, expected to reduce CAPEX costs of the floating wind generation. Seaplace’s active ballast control system is used to ballast/de-ballast the unit, changing the floater from its transport draft to its operational draft and vice versa. The system can also be used to partially or fully compensate the mean tilt produced by the wind loads improving the stability of floating offshore wind platforms.

The system can be used to stabilise the platform if a compartment is damaged, improving the safety level of the floating platform. Additionally, the system’s level of redundancy ensures it will still function even if one component, such as a valve or pump, fails for any reason.

The system was reviewed against applicable Rules and Regulations for the Classification of Offshore Units, including the acceptance of preliminary Failure Modes Effects and Criticality Analysis (FMECA) of the system. In addition, its software allows for remote manual operation, semi-automatic control and automatic operation.

Seaplace’s system, which has been designed to be used with different types of floating wind platforms, was first tested with software-in-the-loop tests and then with scale model tests performed at the IH Cantabria Offshore basin, as part of the CROWN project.

Approval in Principle forms part of the final phase of the CROWN technology development which enables Seaplace to move forward with the full-size demonstration concept.
