Delivered to the Republic of Cape Verde last month, the Damen Stan Patrol SPA 5009 is based on their Fast Crew Supplier (FCS) 5009. This vessel features a single ‘Axe Bow’ which delivers high speeds with low fuel consumption. Although more than 60 Damen Sea Axe vessels have already been delivered as Crew Boats and FCS, the Cape Verde order is the first Offshore Patrol Vessel version.

The Sea Axe concept was developed for patrol boats by a team combining Damen Shipyards, Delft Technical University, the US Coast Guard, the Royal Netherlands Navy, and Maritime Research Institute of the Netherlands (MARIN). Rather than bouncing over waves, the Sea Axe design cuts through them, limiting speed degradation due to wind and waves.
The wheelhouse is in weight saving aluminum, however extensive Finite Element analyses showed that steel was the best construction material for the Stan Patrol 5009 hull, enabling it to sail at maximum speed under all circumstances without distressing the crew or the ship itself. There is accommodation for 18 persons in 11 cabins.
The LOA is 50 m, beam 9.4 m and draft 3.5 m. A propulsion system of four main engines driving four shafts via Reintjes WVS 730 reverse reduction gearboxes with four fixed pitch propellers, delivers a maximum speed of 23 knots. Main engines are Caterpllar C32 each delivering 1450 hp (1081 kW) at 2300 rpm giving a total installed power of 4,324 kW. There are two 107kVA gensets producing 230/440V at 50 Hz. According to the builders, the SPA 5009 can be fitted with more powerful engines up to a total power of 12,000 kW to give a speed in the region of 35 kn.
In keeping with its duties, the patrol ship has a launch and recovery ramp built into the stern for a 7.5 m RIB powered by an inboard diesel driving a waterjet. This boat has a crew of six persons and a top speed of about 30 kn.
