How much could barnacles limit shipping’s decarbonisation?

This white paper confirms barnacle biofouling is a big burden for the shipping industry. Nearly one-fifth of a sample group comprising 685 vessels inspected in dry dock were found to have more than 20% of their hull surface covered by barnacles, a new study has found. High levels of barnacle biofouling on underwater hulls across the global shipping fleet can significantly drag down decarbonisation efforts and increase fuel costs.
