Cummins QSK95 Propulsion for Ferry Newbuild

Azam Marine’s next newbuild, Kilimanjaro VII, will be the ? rst passenger ferry powered by QSK95 propulsion engines from engine manufacturer

Cummins. Two QSK95 propulsion engines will provide main propulsion power to the new Incat Crowther designed fast catamaran, which will be built by Australia’s Richardson Devine Marine in Tasmania. Cummins said the QSK95 offers a power output previously exclusive to medium-speed marine engines with power ratings from 3,200 hp to 4,200 hp for propul- sion, auxiliary, generator and diesel electric applications. Azam Marine and

Coastal Fast Ferries operate passenger ferries between the islands of Zanzi- bar, Pemba and mainland Tanzania. The 45-meter Kilimanjaro VII will be the largest of the seven vessels in the ? eet.
