The 1978 Protocols to MARPOL 1973 and SOLAS 1974 will have a considerable effect upon the design and construction of new crude carriers and products tankers. This paper attempts to highlight those aspects of the Protocols having the greatest effect on the design of new tankers. A number of designs have been chosen, in the range 20,000-200,000 tons deadweight, to demonstrate the problems associated with optimising the positioning of longitudinal and transverse bulkheads within the cargo tank/segregated ballast spaces, to meet the Protective Location requirements for segregated ballast and maximum oil outflow limitations laid down in MARPOL 1973 and the 1978 Protocol. The paper also considers the problems associated with draught, trim, freeboard, stability and tonnage for the chosen designs as required by the appropriate Conventions, and the effect the 1978 Protocols have upon these requirements. The new requirements for Crude Oil Washing and Inert Gas installations are also commented upon in the paper together with a section describing possible pumping and piping arrangements.
