In-Water Cleaning Update

Posted on Feb 9, 2018 in Main, slider

In-water cleaning (IWC) of vessels is not allowed in the State of Hawai`i due to the potential biosecurity risks and release of vessel antifouling paint that may degrade water quality. However, IWC of vessels is a useful method of biofouling management between dry-dockings, thereby minimizing biosecurity risks associated with overgrowth in addition to improving vessel fuel efficiency and concomitantly, carbon emissions.

DLNR seeks to coordinate a resolution among overlapping jurisdictions on IWC of vessels through the adoption of the HISC IWC Resolution 18-1 (adopted January 18, 2018) by the HISC Council, which includes department heads representing Hawai`i DOT, DOH, DLNR, DBEDT, DOA, and the University of Hawai`i.  The HISC IWC Resolution recognizes the need for high-level coordination among government agencies with overlapping jurisdictions on vessel IWC, to develop conditions for (1) allowing IWC of vessels that pose minimal biosecurity and hull paint release risks, and (2) supporting data collection and testing of IWC debris capture technology in Hawai`i in collaboration with the Alliance for Coastal Technologies (ACT).

An update on the progress of the HISC IWC Resolution implementation was provided in a Brown Bag presentation on February 2, 2018.  The PDF powerpoint can be accessed here: AAOTF Brown Bag_upload

 

Additionally, reference material that will be used to develop IWC conditions include the following links from the New Zealand Ministry for Primary Industries, the federal agency managing biosecurity risks associated with vessel biofouling in New Zealand:
