Cost-Benefit Analysis of Ship’s Hull Maintenance Scenarios in the Kattegat and Danish Strait Route

Paper i proceeding, 2024

This study conducts a cost-benefit analysis of various hull maintenance scenarios using the support tool HullMASTER. The analyses provide examples of a ship operating in the Kattegat-Danish Strait. This study indicates that increased hull roughness due to biofouling and hull maintenance, compared to hydraulically smooth hulls, can escalate operational and socio-environmental costs by 6 and 7.2 times. Among the evaluated coatings, non-biocidal foul-release coatings are identified as the most sustainable option by reducing climate change and health damage, and biocide release into the ocean. It also highlights the importance of proper maintenance and the need for sustainable long-term planning.
