Manukai / Maunawili - Container Ships

The sisterships Manukai and Maunawili were built at the Kvaerner Philadelphia shipyard for Matson Navigation. The Manukai, delivered in 2003, represents the first delivery from the shipyard. The Muanawili was delivered mid-2004 at a cost of $110 million. The ships have been designed to meet Hawaii's current and future market requirements. Foremost among those is the additional capacity for large container sizes, such as 20ft, 24ft, 40ft, 45ft and even 53ft boxes. The total TEU capacity for each ship is 3,000 units.

The main engine is a MAN B&W 8K80MC-C unit, manufactured by Hyundai Heavy industries. It has an output of 28,800kW when driven at 104rpm. This consumes 100t/d of fuel, with the auxiliaries consuming a further 25t/d.

The ships' bunkers include 3,700m³ of heavy fuel oil, 180m³ of diesel oil and 11,600m³ of water ballast.

The engine is linked to a Nickel-Aluminium-bronze medium skew propeller, designed and manufactured by Mecklenburger Metalguss. The fixed pitch propeller is 7,200mm in diameter.

For manoeuvring, there is a Brunvoll tunnel-type bow thruster featuring a controllable-pitch propeller with an output of 1,300kW. The mooring equipment includes two mooring winches / windlasses and five mooring winches, all made by Kocks.

Power is provided by four diesel-driven alternators. There are two MaK 8M20 units and two 9M20 units. The former have an output of 1,360kW at a speed of 900rpm while the latter have an output of 1,530kW at 900rpm. The main composite boiler is made by Aalborg; it has an output of 3,200kg/h from each side.
