A Multi-Objective Optimisation-Based Structural Design Procedure for the Concept Stage - A Chemical Product Tanker Case Study

摘要

The paper presents a structural design procedure based on multi-objective optimisation and using a decision-support algorithm to identify the competitive optimum. The procedure is applied to a chemical product tanker. In addition to the rule compliance under service loading, optimisation is performed with respect to the ship weight, production cost or service life. Appropriate assumptions and simplifications are proposed for not yet known structural solutions or loading conditions. Objectives of the stakeholders are identified in interviews. The paper studies the influence of various objectives on the resulting structural alternatives.
