Abstract [en]

The importance of light weight material is increasing, especially for transport applications resulting in reduced fuel consumption. In the Swedish project LASS, Lightweight construction applications at sea, a number of different types of ships have been studied with emphasis to improve efficiency by reducing structural weight. One part of the project encompasses investigation of life cycle effects to demonstrate the environmental benefits and economic potentials when changing from traditional materials to lightweight materials. All included ship structures are analysed with life cycle cost analysis, LCCA and one of the structures is also investigated environmentally through life cycle assessment, LCA. In all cases the effectiveness in fuel economy is increased. For one of the ship structures, a high speed craft a weight saving around 40% results in decreased operation cost with 20% over 20 year of use. The weight savings can also be utilized as an increase in payload resulting in decreased energy consumption per transported payload. This is the case for a Ro-Ro ship investigated, resulting in a break-even after about 4 year when changing from steel to aluminium of the superstructure.
