Parametric structural design is a promising alternative for hull design, capable of combining weight reduction, material efficiency and safety. The challenge of investigating a large space of alternatives created by the parametric model is caused by the high amount of engineering time required to model, analyse and evaluate each of the possible configurations. The objective of this paper is thus to demonstrate the application of a design of experiments sensitivity study for a parametrically modelled global structure of a platform supply vessel with a focus on mass reduction during the conceptual design phase (CDP). The focus on CDP allows for simplifications in the model, thus gaining computational time by reducing discretisation. As a result, knowledge on the impact of design variables on various combined responses is obtained and used to determine a viable alternative within the solution space that has better material usage in comparison to a base case design.
