Technical and Economical Evaluation for Fishing Vessels

Abstract

In this paper, fishing vessel, fishing ground and fishing port are looked upon as a system, and that the influence of "uncertainties" are considered into this system. The economic analysis is made for ice trawler as an example. Authors point out that realizing optimum vessel type under the variation of some "uncertainties" is difficult, but the "satisfactory" design can be obtained. Therefore, the condition of "satisfaction" can be kept on economic nature for fishing vessels under the variation of different "uncertainties". This paper proposes the method and the steps while considering the influence of "uncertainties". It also suggests that the principle of the method and the steps of treatment can be applied into technical and economical evaluation of other vessel types for specification of hull, machinery and equipments (i.e. owners requirements).
