Practical ship structure optimisation for sustainable structures
conference paper
With an increase in steel demand, climate change, and material scarcity, reclaiming and repurposing materials is and will be an essential part of green economies. Although modifying and repurposing structures and structural parts is nothing new in shipbuilding, repurposing parts designed to perform on the cutting edge introduces novel challenges as (more) damage could have accumulated. An optimisation problem arises which requires an approach that is both practical and fast: practical, in the sense of the optimisation taking into account the nature of the design process and ship production and the discrete input parameters, as well as fast, in the sense of algorithmic capabilities. Since incorporating repurposed elements in an optimised structure is a deviation from the current practice, where the ship is typically optimised for weight and/or cost, this problem first requires a holistic view of what is defined as an efficient structure. The objective function should not only optimise for cost and/or weight but should incorporate the environmental impact to express the benefits of repurposed components. This paper explores how to combine ship design, ship structure optimisation, environmental impact indicators and their state-of-the-art to design and build optimised and sustainable structures.
