Inwater Cleaning Technologies


After many years working together, Biofouling Solutions Pty Ltd. (BFS) and Mr Derek Tan (Leading Marine Technology Pte Ltd) have combined forces, integrating our respective strengths to offer technical expertise in commercial diving, innovative solutions to biofouling and invasive marine species management backed by excellence in marine biosecurity science.

BFS will work collaboratively with Mr Tan, who has been appointed as Chief Technical Designer & Development Advisor, to maintain and further develop innovative in-water cleaning and treatment technologies.

BFS recognize Mr Tan as an industry leader in the development of innovative inwater cleaning and treatment technologies, and have long been impressed with his integrity and commitment to improving commercial diving safety standards.

We believe our integrated resources will strengthen and support the on-going development of new scientifically proven, cost-effective and user-friendly inwater cleaning and treatment technologies, for hull grooming to reduce fuel consumption and the unwanted dispersal of invasive marine species.



The Smart Kart 6 is more than just another brush kart….

…. it’s a smart investment!

The Smart Kart 6 is a hydraulically powered, diver-operated ship hull grooming and cleaning machine. It's the new generation of brush kart design!

It is capable of performing in a safe, reliable, efficient and effective manner due to its clever design. This design is also able to minimize diver fatigue as the machine's central thruster ensures that it’s easy to handle.

What makes our version of a brush kart smart, is down to its very specific and thoughtfully considered design. A design we have taken 25 years to perfect! Our smart design enables the diver operator to freely adjust settings on the machine to respond to changing conditions experienced during the grooming and cleaning process. It’s able to perform delicate grooming operations right through to cleaning the heaviest levels of marine growth.  

The smart construction of the Smart Kart 6 incorporates the highest quality materials to minimize breakdowns and downtime due to unnecessary wear and tear. The Smart Kart 6’s buoyancy will not change over time and our high-quality foam will not absorb water.

The Smart Kart 6 not only has a clever, reliable and robust design – but it also looks good! Every piece is constructed and fitted by hand with care and attention to detail.

 **  International Paint has assessed and evaluated the Smart Kart hull cleaning equipment for cleaning slime and light weeds. For the evaluation, the Smart Kart was using 0.69mm nylon brushes (SK-BSH-001) and rubber wheels (SK-RW-002). The dive company associated, successfully completed International Paint’s Intersleek® underwater cleaning panel tests under the supervision of an International Paint Representative and no damage was seen that could be attributed to the cleaning equipment. **

**Currently we have multiple Smart Kart 6 ready to ship now – no lead time**


The Underwater Multi-Tool is one tool that does it all!

The Underwater Multi-Tool is a hydraulically powered multi-purpose hand-held machine that has been refined over a period of 25 years. It has changeable adapters that allow the machine to be easily and quickly converted to undertake underwater drilling, grinding, cutting, polishing and targeted grooming/brushing activities.

The machine has interchangeable handle configurations that allow a diver to customise and set the multi-tool up the best way for a particular task.

The Underwater Multi-tool will handle back pressure due to motor load up (when excessive force or a jam occurs) better than any other underwater hydraulic tool available. The Underwater Multi-tool has an extra return line, allowing a faster free flow return and no hydraulic oil leaks.

When you own an Underwater Multi-tool you only have to service and maintain ONE tool! Not FIVE separate tools. The Underwater Multi-tool is designed to be very easy and cost effective for the owner to conduct the general service when required.
