Abstract :
[en] The aim of this paper is to investigate the effect of the change in structural weight due to optimisation experiments on life
cycle cost and earning elements using the life cycle cost/earning model, which was developed for structure optimisation. The
relation between structural variables and relevant cost/earning elements are explored and discussed in detail. The developed
model is restricted to the relevant life cycle cost and earning elements, namely production cost, periodic maintenance cost,
fuel oil cost, operational earning and dismantling earning. Therefore it is important to emphasise here that the cost/earning
figure calculated through the developed methodology will not be a full life cycle cost/earning value for a subject vessel, but
will be the relevant life cycle cost/earning value. As one of the main focuses of this paper is the maintenance/repair issue, the
data was collected from a number of ship operators and was solely used for the purpose of regression analysis. An illustrative
example for a chemical tanker is provided to show the applicability of the proposed approach.
