IMPROVING DECISION-MAKING FOR PAINT SELECTION AND MAINTENANCE PROGRAMMING. THE ECONOMICS OF THE TOTAL OPERATION
The Author, of Ellerman Lines Ltd, discusses the principles on which depend the economics of coating systems for the corrosion protection of hulls. The law of diminishing returns will apply to these systems, and as far as costs are concerned it is only worthwhile to invest up to the point where the marginal benefit equals the marginal cost. This is a critical point to identify, and involves the cost-effectiveness of competitive products. The Author's purpose is to suggest a procedure, rather than to specify the best solution, for those who have to make decisions on selecting which protection system to employ. The suggested procedure is discussed under the headings:--(i) Defining Cost-Effectiveness. (ii) Identifying the Economic Variables. (iii) A Framework for Evaluating Alternatives. (iv) The Uncertainties and their Implications. Under (iii), the comparison of the cost-effectiveness of alternative protection systems is considered (with a numerical example) in respect (a) the cost of providing the initial protection before the ship is delivered; (b) the additional periodic costs of maintaining the system; (c) the incremental operating costs, due to variations in ship performance with condition of coating; and (d) the residual value of the ship when it is disposed of.
