The possibilities of limiting the toxic compound emission from Diesel engines and boilers during ship’s stay in harbour

During their stay in harbours the ships generate the electric energy and heat for their needs most frequently by use of their own power and boiler plants through Diesel generating sets and oil fired boiler. The operation of this machinery causes the toxic compound emission to the atmosphere. In this article the possibilities are presented of limiting this emission through such activities as supplying the ship with the energy from the shore power network, from barge-situated power plant provided with the Diesel generating sets supplied with LNG, and in case of the boiler plant through the application of the liquid or solid biofuel. There are also presented some selected results of the simplified comparative analysis of the emission levels with the various methods of generating the electric energy and heat during ship’s stay in harbour.
