Patrol and government service vessels

Rotor / wing / sail units

The rotor sails, rigid wings or suction sails that generate thrust from the wind, reducing the power the engine must supply.

Foundation / turntable structures

The foundations and turntables carrying each unit's considerable loads into the ship's structure.

Drive and actuation system

The drives spinning or trimming each unit to the angle that extracts most thrust from the present wind.

WAPS control and optimization system

The controller trimming the units automatically and quantifying the fuel saved — the number the investment is judged on.

Wind and structural-load sensors

Sensors reading apparent wind and the loads in the structures, both to optimise and to protect in heavy weather.

Stowage / retraction arrangement

The means to lower or fold units for air-draught limits under bridges and at cargo-working berths.
