Proposal of ecological propulsion for seagoing ships

Górski Z., Ćwilewicz R.

Journal of KONES

Exhaust gases from engines of seagoing ships are the serious problem for environment. That is why the discussion in the matter is very important. One of means to minimise harmful substances emission to earth atmosphere is application of „ecological fuel" — natural gas or nuclear energy for ship propulsion. Natural gas is commonly used in onshore applications but is rarely applied in marine propulsion. Heavy Fuel Oil is the basic brand of fuel used onboard ofseagoing ships. Other kinds of fuel e.g. Diesel Oil or gas Oil are used on smaller ships with limited sailing range. The nuclear energy, due to high costs is used only on few types of warships and some icebreakers. A real means for minimising harmful substances in exhaust gases from ships engines is replacement of Heavy Fuel Oil by Natural gas. Nowadays, heavy oil is commonly used due to technical and logistic abilities and conservative attitude of ship owners. The necessity of improvement in the field of environment protection inclines towards wide application of Natural gas as marine fuel. Application power-plant novel type would break the traditionalism in the shipbuilding and the introduction novel generation ofshipping drives.
