Sustainable ship hull maintenance through development of decision support to the maritime industry and authorities
Research Project, 2019 – 2021

About the HÅLL project

HÅLL is a collaboration project between Chalmers University of Technology, SSPA and the University of Gothenburg. The project is funded by Lighthouse and will run until the end of 2021.
The HÅLL project aims to provide decision support to maritime actors (ship operation, maintenance and paint manufacturers) as well as responsible environmental authorities. Sustainable maintenance strategies will be achieved by optimizing the choice of antifouling system and the type and frequency of hull maintenance work. The project will evaluate different antifouling strategies with respect to cost, efficiency and emissions to air and water.

Collaboration with industry
The HÅLL project is collaborating with ship owners to evaluate maintenance strategies for different vessel types. For the collaborating ship owners, the project will deliver tailored solutions on how to become more sustainable with regard to ship hull maintenance strategies.
