TANKER PRELIMINARY DESIGN ECONOMICS

This paper explains a computer assisted procedure for selecting the major technical characteristics of a tanker. Although developed for one particular service (Persian Gulf to U. S. East Coast via the Cape of Good Hope), the procedure is applicable to bulk carriers in general. The design method involves initial inputs such as maximum allowable draft and length. It uses a direct search technique to find the optimal combination of length, beam, draft, depth and block coefficient and the optimal speed. Optimality is based on minimizing the required freight rate. The following general conclusions are reached: 1) The block coefficient should be as great as practical conditions will allow. 2) Beam-draft ratios in excess of any now found in sea-going ships deserve consideration. 3) Service speeds of more than 17 knots do not seem economical. The application of a methodical search method allows a quicker and cheaper determination of the most economical ship characteristics than any method known to be in use today. The cost of a computer run for this particular tanker program is approximately two dollars. No graphical methods are necessary as is the case in other publications on this subject.
