Power plants running for more than 6,000 hours/year, i.e. generating power for continuous use.

A transverse thruster mounted in the bow of a ship to make manoeuvring easier in harbours.

The compensated tonnage of a ship, i.e. the ship’s volume adjusted (compensated) by a factor to render the amount of work at the yard equivalent for dif-ferent types and sizes of ship. 

Coastal and Inland Propulsion System. A tailor-made propulsion system with small fixed pitch propellers (diameter below 3.5 m) suitable for inland navigation vessels, fishery vessels, coasters and luxury (mega) yachts.

Carbon dioxide. A component in exhaust gases formed when fossil fuels are burned. The most significant greenhouse gas in the atmosphere; it prevents thermal radiation entering the atmosphere from being reflected back into space. 

The simultaneous generation of electricity and heat. Also called Combined Heat and Power (CHP)

The use of two different power generation processes, e.g. fuel engines and steam turbines, in the same power plant. The second process utilizes the heat recovered from the first.  Combined Heat and Power (CHP) = This method raises total efficiency to above 90% since the heat produced by power generation is recovered and used, for example, in indust [..]

A method of fuel injection that eliminates the principle of one pump/cylinder. The common rail is constructed from a series of accumulators inter-connected by small-bore piping. The injection pressure is adjusted as desired and the injection timing (start and stop) controlled electronically. Wärtsilä has used common rail technology to develop the “ [..]

A propeller whose pitch can be controlled (changed) by rotating the blades with a hydraulic or electro-mechanical system in the propeller’s hub.

Technology utilizing waste heats from diesel engine for additional el-generation via a steam turbine.
