Reasons for investigating the feasibility of large tankers with considerably wider beam and shallower draught than conventional large tankers are: (i) The possibility of reducing transportation costs without imposing a need for additional dredging and harbour works. (ii) A doubt as to whether conventional proportions are the most favourable economically. (iii) The lack of data for parametric studies on this subject. The Author discusses these reasons and examines the economic and technical feasibility of such ships (relevant investigations are still in progress). Among the aspects considered are: required freight rate compared with that of conventionally-proportioned tankers, with and without additional dredging and harbour costs being taken into consideration for the conventional ships (the comparisons are approximate at present); the wide shallow hull-form and its resistance and propulsive efficiency; number of shafts and type of propulsion plant; hull subdivision and IMCO anti-pollution requirements; and structural strength and steel weight (these are among the matters being further investigated.
