An innovative underwater vacuum developed by marine services firm Franmarine aims to tackle biofouling on commercial vessel hulls, thereby reducing the risk of invasive marine pests entering Western Australia (WA) waters. This technology employs a diver-operated vacuum linked to a filtration system that removes algae and marine life. The filtered water is treated with UV radiation before being released back into the ocean.
The Department of Primary Industries and Regional Development (DPIRD) is collaborating with Fremantle Ports to evaluate this hull cleaning technology against Australian in-water cleaning draft guidelines. Senior researcher Samantha Bridgwood emphasized that the system is a significant advancement in managing vessel biofouling, helping to protect marine biodiversity.
Currently undergoing scientific assessment, the technology must meet strict biosecurity and contaminant capture standards. If successful, a larger commercial pilot program will be launched in Fremantle Ports’ waters. Bridgwood noted that this initiative exemplifies WA’s leadership in developing marine biosecurity practices that benefit both the environment and the shipping industry. However, maintaining best biosecurity practices remains essential to minimize the risk of invasive species.
