Another offshore vessel cleaning operation undertaken 12 nautical miles offshore. MPI requests that we complete these vessel cleaning operations so far out at sea so that we can ensure that the bio fouling does not make it into New Zealand waters. The cleaning operations are undertaken using a variety of methods including using a hull scrubbing machine, hand scrappers and a water blaster. A report of the cleaned areas is then sent to MPI and the vessel remains offshore until MPI have assessed the photographs and underwater CCTV and given them a clearance to enter New Zealand waters.
