Innovative Underwater Vacuum Technology Aims to Combat Biofouling and Protect WA Waters

Innovative Underwater Vacuum Set to Combat Biofouling in WA Waters

Published on: September 2, 2025

FREMANTLE, WA – In a groundbreaking move for marine biosecurity, an innovative underwater vacuum is being tested to tackle the persistent problem of biofouling on the hulls of commercial vessels. This technology aims to significantly reduce the risk of invasive marine pests being released into Western Australia’s pristine waters.

Developed by marine services firm Franmarine, the underwater vacuum system is designed to efficiently remove accumulated algae and other marine life from vessel hulls in a biosecure manner. The system operates with a diver-operated vacuum connected to a sophisticated filtration setup that captures organic matter. The filtered water is then treated with UV radiation before being safely returned to the ocean, ensuring minimal impact on the marine ecosystem.

The Department of Primary Industries and Regional Development (DPIRD) is collaborating with Fremantle Ports to evaluate this cutting-edge technology against Australia’s draft in-water cleaning guidelines. Samantha Bridgwood, a senior researcher in Aquatic Pest Biosecurity at DPIRD, expressed enthusiasm about the potential of this initiative.

“This hull cleaning system is currently undergoing scientific assessment to ensure it meets strict biosecurity and chemical contaminant capture standards outlined in the draft national guidelines,” Bridgwood stated. “If successful, we plan to roll out a larger commercial pilot program in Fremantle Ports’ waters.”

The initiative is not just a technological advancement; it represents Western Australia’s commitment to leading the way in marine biosecurity practices that protect the region’s rich biodiversity. Bridgwood emphasized the importance of maintaining best practices in biosecurity, noting that while this technology is a significant step forward, it does not replace the need for proactive measures to minimize biofouling.

The collaboration between DPIRD and Fremantle Ports highlights the critical role of innovation in safeguarding the marine environment while supporting the shipping industry. As the world grapples with the challenges posed by invasive species, this initiative could serve as a model for other regions facing similar threats.

As the testing phase progresses, stakeholders are optimistic that this underwater vacuum will pave the way for a cleaner, safer marine environment in Western Australia, ensuring that the waters remain vibrant and healthy for generations to come.
