TECHNO-ECONOMIC CONSEQUENCES OF ENVIRONMENTAL PROTECTION MEASURES FOR SEAGOING SHIPS (PARTS 1 AND 2)

After giving some general information on the environmental protection requirements of the IMCO Convention (1973) and the Baltic Convention (1974), the Author (of the East German shipping board) examines the possible techno-economic effects of these requirements. In Part 1, ships in general are considered in relation to the measures that will be required to meet the requirements for protection of the sea against pollution from engine-room fuels and lubricants and from sewage and other wastes. The measures will lead to additional costs for building (or modification) and higher operating costs, and may, through their effect will depend primarily on ship type and size, machinery type and power, crew size, operating conditions, and the technical measures taken to meet the requirements. On the whole, however, the measures taken will have a comparatively small effect on building and operating costs. In Part 2, the larger part of the article, protection against pollution due to oil-tanker cargoes is examined with special reference to the techno-economic effects of the 1973 IMCO Convention requirements. Tank-size limitation, the load-on-top system, and segregated ballast-tanks are discussed in some detail. The effects of the Convention will depend very largely on the particular ship and its operating conditions, but become more pronounced as ship size increases. It is estimated that, for tankers smaller than 70,000 dwt, the techno-economic consequences of the Convention will be comparatively small; tankers in the 70,000-200,000 dwt range will show an increase of about 5% in building costs; those of over 200,000 dwt will show an even greater increase in building costs, the estimated increase for ships above 450,000 dwt being about 25% plus an increase of about 10 to 15% in operating costs.
