Environmental Improvements in Ship Design by the Use of Scoring Functions

Abstract

The introduction of environmental aspects in ship design requires a holistic view of the design process. The designer needs to integrate environmental knowledge with the design process without increasing calendar time for the design work. A design tool that supports trade-off analyses with environmental objectives will be presented in this paper.

Interviews with experienced ship designers have been conducted to support the mapping of the ship design process. This has resulted in identification of decision points, where environmental aspects could be addressed, and has shown the possibilities of the aforementioned integration.

The aim has been to show a design tool that is able to manage geographical differences in sensitivity, when it comes to environmental effects from a ship. The paper will point out changes in approach to include this tool in the design process.

This paper demonstrates so-called scoring functions in-a trade-situation with environmental information. The tool produced keeps a lot of information ready at an early stage in the design process and deals with the issue of changing environmental sensitivity in the ship surroundings. Recommendations are given on further development for the use of environmentally focused scoring functions in ship design.
