Abstract

Design of special ships equipped with non- conventional de-oiling equipment for cleaning oily ship's waters and removal of oily spills J. Listewnik Institute of Ship Propulsion Plant Operation Maritime University Szczecin, Poland Abstract During the last 30 years pollution of the world's oceans has become a matter of increasing international concern. Most of it originates from land-based sources. Nevertheless, a significant amount of pollution is caused by shipping and maritime activities generally. In tonnage terms the most important pollutant resulting from shipping operations is oil. In the introductory part of the paper an assessment of the amount of oil damped into the seas from ships is made. Shortcomings of the de-oiling systems installed on ships today are discussed. To reduce further the oil pollution threat more effective methods of oil separation from ship's bilge and ballast waters are proposed. A better solution to avoid oil pollution seems to be disposal of oi
