The Cape Town-based yard Nautic Africa is building seven 35 m fast multi-role patrol vessels for undisclosed West African clients for a total value of ZAR600 million (USD60 million).

The first two are currently being built, with another three to follow shortly, and Nautic expects to deliver the first vessels in 2014 and complete the contract in 2015.

The contract grew out of previous work for navies and offshore oil companies in West Africa, where Nautic already has a maintenance support facility at Takoradi in Ghana.

CEO James Fisher says the company will now also firm up its plans to establish a second “life-cycle and support” facility in the Gulf of Guinea at Port Harcourt in Nigeria. The company has previously built a number of 30 m, 26 knot utility vessels that are based at Port Harcourt to support the offshore oil industry.

The aluminium patrol boats will have South African developed ‘Super Shield’ composite armour protection for their wheelhouses and a full-load displacement of 175 tonnes, a beam of 7.5 m and a draught of 1.4 m.

Powered by three 1,193 kW Caterpillar C32 ACERT engines driving three shafts, they have a maximum speed of 28 kts, a range of 2,130 km at their normal cruising speed of 20 kts and 7,590 km when speed is reduced to 10 kts for extended patrols. Electrical power is provided by two Caterpillar C4.4 107 kVA generators.

The vessels have a crew of six in standard configuration, with accommodation for up to 12 passengers or additional personnel, and are designed to carry up to two of Nautic’s BR850-TPD Guardian interceptors for boarding work. These are launched using a single-point system.

The Guardian is an 8.5 m aluminium craft with 2.8 m beam and 60 cm draught and a full load displacement of 3.8 tonnes. The shallow draft combines with a 373 kW diesel with a tunnel propeller drive to allow operations close to the shore and in river deltas.

They have a maximum speed of 42 kts with a range of 295 km at that speed, or a 700 km range at 20 kts for inshore patrol or similar tasks. They are designed for a crew of two with space for a six-strong boarding party, and can be fitted with shock-mitigating seats if intended for high-speed intercept missions. Their systems include a GPS/chart plotter and a 2 kW 4G broadband radar.
