Biofilm is a complex layer of microorganisms that adheres to wet surfaces such as tanks, ship hulls, pipelines, cooling systems, and offshore structures.
Once established, it acts as a protective shield for bacteria, algae, and marine organisms, accelerating the process of biofouling.
Unmanaged biofouling leads to clogged pipelines, corroded infrastructure, increased drag on vessels, and severe ecological and economic impacts.
In the shipping industry alone, biofouling can increase hydrodynamic drag by 25–35%, resulting in higher fuel consumption, elevated emissions, and costly operational downtime.
At Samthan Shedge, we deliver sustainable, chemical-free antifouling solutions designed for aquaculture, marine industries, shipping, offshore energy, oil & gas platforms, wind turbines, and coastal structures.
Our approach transforms advanced science into practical tools that increase efficiency, reduce costs, and support environmental responsibility.
A fouled hull leads to higher resistance, increased fuel consumption, corrosion, and decreased operational performance. Conventional coatings and antifouling paints require frequent replacement, pose environmental risks, and degrade in efficiency over time.
Our ultrasonic hull protection system targets the root cause—biofilm formation—preventing barnacles, mussels, algae, and other organisms from attaching to the hull.
Key advantages
This enables vessel operators to maintain optimal performance and lower operating expenses.
Propellers and shafts are among the most critical components of a vessel, and even minor fouling dramatically increases drag. Because the propeller operates at high rotational speed, fouling has an even greater negative impact on fuel efficiency compared to hull fouling.
Consequences of propeller fouling include
Ultrasonic antifouling provides continuous protection by preventing the attachment of marine organisms and eliminating calcareous deposits. This reduces manual cleaning frequency, conserves fuel, lowers operating costs, and prolongs the life of propulsion components.

Clean fuel tanks are critical for reliable engine performance. Contaminants such as sludge, sediments, and microbial growth contribute to
Chemical biocides often worsen the problem by breaking contaminants into smaller particles, spreading biofilm throughout the system.
Our ultrasonic technology prevents the formation of biofilm at its source, keeping tanks cleaner for longer.
Benefits include
This is a cost-effective, long-term solution to a widespread fuel system challenge.
The offshore oil & gas sector faces persistent challenges from biofouling on submerged equipment, pipelines, risers, cooling systems, and platform structures. Fouling contributes to reduced flow rates, corrosion, inefficient heat transfer, and expensive cleaning cycles.
Samthan Shedge provides GAT Group’s ultrasonic antifouling technology, offering a comprehensive, environmentally responsible solution tailored for offshore assets.
Key Benefits for Oil & Gas Operations
1. Flow Assurance
Biofouling narrows pipeline diameter, increasing pressure and reducing throughput. Ultrasonic systems prevent buildup, ensuring predictable and stable flow performance.
2. Corrosion Reduction
Biofilms can accelerate microbiologically induced corrosion (MIC). By preventing biofilm formation, our solutions extend the lifespan of critical infrastructure.
3. Reduced Maintenance & Downtime
Mechanical cleaning, pigging, and chemical dosing are costly and interrupt production. Ultrasonics significantly reduce the frequency of interventions.
4. Environmentally Responsible
Chemical treatments introduce toxins into marine ecosystems. Ultrasonic technology is a clean, sustainable, and compliant alternative that aligns with global ESG goals.
5. Versatility Across Offshore Applications Applicable to:
By adopting GAT Group’s advanced ultrasonic systems, the oil & gas industry can improve reliability, reduce operating expenditures, and lower environmental impact.
Yes. The system must operate continually to repel organisms away from the surface.
No. our systems function as a deterrent - it cannot retroactively remove existing fouling which has already cemented or rooted into the surface.
Much less frequently. Depending on the conditions, BPS can easily extendthe time between cleaning to over 12 months. We still recommend checking your hull at least twice a year..
Yes. BPS systems are designed to integrate into your existing battery system - either directly to a 12V system, or through a DC/DC converter when used on vessels with only 24V battery systems.
No. Ultrasound is perfectly safe for your boat and should not interfere with your sonar or depth finder reception.
Never. Transducers are attached directly to the surface, there are no through-holes.
We always recommend our product for use with a bottom paint. Ultrasonic antifouling can greatly reduce the frequency of maintenance and cleaning of the hull. This extends the lifespan of the bottom paint because the hull is staying cleaner longer with less abrasive cleaning processes.
No problem! Since BPS systems are installed in the hull, you can install our systems in the water. Since we cannot remove any existing growth, we recommend a clean hull to start, and two dive cleanings at least 30 days apart.
