Propulsion Solutions

Propulsion Solutions of Kumera Marine AS in Hjelseth are proven to be highly efficient in a complete range of driveline setups. Based on our engineering capabilities and wide experience, we have developed powerful solutions together with vessel designers and owners within a wide range of setups





Application – Conventional Vessels

Conventional Vessels – operating at a low and medium speed – is a wide group of vessels in which Propulsion Solutions of Kumera Marine AS in Hjelseth are well fitted. Since most of these vessels operate in continuous duty, fuel-economy and systems reliability are key requirements. For most workboats, bollard pull is also an important performance criterion.

Cargo Vessel,

Aquaculture Service Vessel,
Catamaran, LOA 24,0 mtr.

Live Fish Carrier,
LOA 84,6 mtr.

Fishing Vessel,
LOA 28,0 mtr

Application – High Speed Vessels

For High Speed Vessels – normally operating at above 25 knots speed – hydrodynamics become much more important for the optimization of the propulsion solution. In addition to the propeller design also the design of brackets, rudders and propeller tunnel has to be optimized. Due to interaction with the hull design, we work closely with the vessel designers on most high speed applications to ensure the most efficient solution.
