Nigeria LNG takes delivery of two 20 m cat ferries

MARCH 23, 2017 — Singapore's SAM Aluminium shipyard has delivered Confidence 1 and Confidence 2, the first two of four 20 m Incat Crowther design catamaran passenger ferries. Designed to support Nigeria LNG Limited (NLNG) with operations to Bonny Island in the Gulf of Guinea, the vessels carry 50 passengers with luggage, along with additional "hot shot" cargo and have crew accommodations.

Built to operate in Sea Area 2, with a sea state up to 2.5 m wave height, the vessels have a rugged hull structure, good tunnel clearance and ample bow height. This ruggedness is combined with an efficient hull form and a simple and sleek superstructure.

The exterior aft deck provides 25 sq.m of cargo space. Passengers board via the aft deck through to the main cabin. The cabin features 50 large comfortable seats with a pair of toilets located aft.

The half-height wheelhouse offers good all-round visibility and is accessed directly from the forward crew space, enhancing security. Foredeck access is also via the crew space.

Confidence 1 and Confidence 2 are powered by twin Caterpillar C18 Acert main engines producing 599 kW each and driving Hamilton HJ403 water jets. Water jets were selected for shallow water performance, and to reduce the likelihood of damage from river debris. In sea trials, the vessels exceeded 30 knots.

Designed to Bureau Veritas NR396, Confidence 1 and Confidence 2 have upgraded stability compliance meeting load line requirements usually required of larger vessels, including increased damaged stability margin.
