The Author examines the net growth in the world general cargo fleet between 1965 and 1972 and extrapolates some quantitative data to give forecasts for major and minor bulk and general cargo movements in the 1980s. The Author's company, Wilh. Wilhemsen of Oslo has recently ordered a number of multi-purpose dry cargo ships from a Japanese yard. These ships are designated as "lipers" to indicate that they can be used both as liners and trampers for certain cargo compositions and in certain port conditions. Deadweight will correspond to about 21,000 tons on a designed draught of 9.75 m although the full scantling version can, if necessary, accept 26,000 tons. The design philosophy of the "liper" is explained and the cargo-handling requirements, both shipboard and land-based for operating these ships are discussed. In conclusion, it is emphasised that the "liper" concept is a temporary measure and will eventually be replaced by more sophisticated designs. These, in turn, will call for a higher degree of port efficiency. Order from: BSRA as No. 46,767.
