Model testing can, broadly, be divided into two categories: general testing, which has been making important contributions to ship design for very many years, and specific tests to aid the designers of individual ships. These specific tests, have, over the years, taken up by far the larger part of model-basin time, and while most of this work is confidential to the clients concerned, the model basins have been able to provide much useful guidance for ship designers in general. The Author, of Three Quays Marine Service (a P. & O. subsidiary), is here concerned with specific tests for the design of new ships, and discusses the reasons for these tests, and the significance of the tests to the designer, under the headings:--Guaranteed Speed; Service Speeds; Propeller Design; Ship/Model Correlation; Service Performance Analysis; Remedial Measures; Avoidance of the Need for Remedial Measures. Model-test programmes are becoming more extensive because of improved techniques and because, with rising costs, owners are increasingly anxious to avoid problems during the service of their ships. The length of time necessary to conduct a comprehensive set of model tests for a new design is considerable, and time limitations imposed by the owner on the builder can lead to subsequent problems. It is suggested that, in such circumstances, the owner should consider arranging two separate contracts, one for design and the other for building. The procedures that would be involved in adopting this proposal are discussed; they would entail a few weeks extra time, but could yield substanial savings in such items as fuel costs and the avoidance of vibration problems.
