摘要:The development of the evaluation method of life cycle fuel consumption from a ship as for a main engine is the aim of the project OCTARVIA: Project for Evaluation of Ship Performance in Actual Seas. The project had been conducted as the 3-years collaborative research of Japanese companies and organizations in a maritime cluster. The packaged GUI program has been prepared, which applied the developed method for external effects due to waves and winds in consideration of fouling and aging. For the evaluation of life cycle performance from an objective perspective, a standard operational model has been proposed and incorporated in the evaluation method and the program. The evaluation method and the applied standard model are described and the result of the evaluation of the life cycle fuel consumption for a ship is considered in the paper.
