Boating and shipping are another market. There are large number of boot and ships in service – all of which need their hulls, tanks and ballasts cleaned and inspected regularly; very labor-intensive and costly.
As most boat owners know, a boat’s hull becomes dirty very quickly. So apart from the few weeks just after an annual maintenance haul-out, most boats sail with a fouled hull. Add to that the regulations restricting biocide usage in antifouling paints, plus the proliferation of microorganisms linked to rising in sea temperatures, and the problem worsens.
