Fence Boom
Fence Boom (EPS Fence)
The fence boom — also known as a fence type or curtain type boom — is a foam-filled marine pollution-prevention boom widely used in ports, marinas, inside breakwaters, and on lakes and rivers. It is the most commonly used oil boom model in Turkey, valued for its straightforward deployment and low maintenance in calm-water environments.
What Is the EPS Fence Boom?
EPS Fence is a fence boom typically manufactured in 25-meter sections, with custom lengths available on request. It is offered in four widths ranging from 580mm to 1200mm. An orange galvanized chain running through the skirt acts as ballast, and all boom hardware is manufactured from sea-resistant materials: stainless steel components are AISI 316 SS grade, and aluminum components are marine-grade aluminum.
Technical Advantages
The fence boom’s greatest advantage is deployment speed. Because its buoyancy comes from foam floats rather than air chambers, it requires no inflation step — unlike an inflatable boom — and can be deployed to a water or river surface immediately. It is low-maintenance and offers a cost-effective containment solution.
Fence booms are best suited to sheltered, calm-water applications such as harbors, marinas, and inland waterways. For open sea or high-wave conditions, EPS Marine’s inflatable boom (Spill Buster) is the recommended alternative.
Connectors are ASTM-Z type, aligned with national regulatory requirements, and joined using stainless steel nuts and bolts. The fabric is PVC-coated polyester, engineered for durable, long-term marine use. Because the boom does not need to be deflated for storage, up to 150 meters of fence boom can be wound onto a single boom reel.
Applications
Port & Marina Protection Line
Ideal as a continuous or emergency containment line at harbor entrances and marina areas.
Inside-Breakwater Applications
Performs efficiently in the sheltered, low-wave conditions found inside breakwaters.
Lake & River Protection
Contains oil and chemical spills on the calm surfaces of lakes and rivers.
Rapid Emergency Response
Requiring no inflation step, it is one of the fastest boom types for field teams to deploy.

EPS Fence is a fence type (curtain type) boom manufactured by EPS Marine. Its foam-filled design lets it be deployed quickly without an inflation step, and it is used to contain oil and chemical spills in ports, marinas, inside breakwaters, lakes, and rivers — calm-water environments rather than open sea. It is offered in four widths from 580mm to 1200mm with a 1:4 buoyancy-to-weight ratio. Steel hardware is AISI 316 SS stainless steel, and connectors are ASTM-Z type. Up to 150 meters can be wound onto a single boom reel. The design is engineered to meet the freeboard, tensile strength, and buoyancy-to-weight ratio criteria referenced in international oil spill contingency frameworks, including the OPRC Convention (International Convention on Oil Pollution Preparedness, Response and Co-operation) and MARPOL Annex I.
FAQ
Where is a fence boom used?
A fence boom is used in relatively calm-water environments such as ports, marinas, inside breakwaters, lakes, and rivers. It is the most widely used oil boom model in Turkey.
How does a fence boom’s buoyancy mechanism work?
The boom stays afloat using internal foam floats. Unlike inflatable booms, it does not require air to be pumped in, which speeds up deployment.
How many meters of fence boom can be wound onto a reel?
A fence boom can be wound onto a boom reel up to a maximum of 150 meters — a smaller capacity than the 500-meter reel capacity of inflatable booms.
What water conditions is the fence boom best suited to?
Fence booms perform best in calm-water environments such as ports, marinas, inside breakwaters, lakes, and rivers. For open sea or high-wave conditions, EPS Marine’s inflatable boom (Spill Buster) is the better fit.
What is the difference between the EPS Fence models?
The EPS Fence line is manufactured in four widths — 700, 850, 1100, and 1200 (650-1200 mm total width). As width increases, freeboard and draft also increase, allowing the boom to withstand higher waves and stronger currents.
Is the fence boom compliant with MARPOL and OPRC requirements?
Yes. EPS Fence is engineered to meet the freeboard, tensile strength, and buoyancy-to-weight ratio criteria referenced in international oil spill contingency frameworks, including the OPRC Convention (International Convention on Oil Pollution Preparedness, Response and Co-operation) and MARPOL Annex I.
What is the difference between a fence boom and an inflatable boom?
A fence boom uses foam floats, deploys quickly, and is easy to maintain, but its performance is limited in open sea and high-wave conditions. An inflatable boom floats via air chambers, offers superior wave-following performance and open sea capability, but requires an inflation step during deployment.
