Over the years, Telko has grown and expanded activities to several geographical areas. Today, Telko operates in 18 different countries globally, expanding from Europe to Asia.

Oil Containment Booms 

Protecting waterways starts with effective containment

Oil containment booms act as floating barriers that prevent spilled oil from spreading across the water's surface and reaching sensitive shorelines, infrastructure, and ecosystems. By concentrating the oil into a controlled area, they support faster recovery operations, reduce environmental impact, and help response teams manage spills safely and efficiently.

Offshore Oil Booms: Reliable Solutions for Deep-Water Spill Response 

When oil spills occur offshore, rapid containment is essential to protect marine environments and minimize damage. DESMI/TELKO offers expert advice, supply, and training on the industry’s most trusted range of offshore oil booms and barriers, designed for durability and performance in challenging conditions.

RO-BOOM: The Global Standard in Offshore Oil Containment

An inflatable boom made with a rubber molding process, built for offshore conditions. An Arctic version is available for extreme cold.

Key features:

  • Section lengths up to 250 m, nine sizes from 0.6 to 3.2 m
  • Deploys 200 m in under 10-15 minutes with a trained crew
  • Individual air chambers: if one deflates, adjacent chambers hold freeboard
  • Lies flat when deflated for storage and cleaning
  • Stainless steel fittings, hot galvanized ballast/tension chain
  • Internal fiberglass rods for skirt profile under tow
  • Resistant to abrasion, oil, and sunlight
  • Accessories: reels, containers, storage bags

Speed Sweep - Heavy duty rubber boom recovery system

DESMI Speed-Sweep System is a cutting-edge oil spill recovery solution, rigorously tested at OHMSETT to ensure maximum performance in demanding offshore conditions. This heavy-duty system enables oil collection at speeds of up to 3 knots, dramatically improving response times and operational efficiency.

Key features

  • Collects oil at speeds up to 3 knots
  • Works standalone or integrated with Ro-Boom systems; towed by one or two vessels
  • Built from Ro-Boom 1500 containment boom with 3 m buoyancy chambers
  • Three 900 mm nets and foam-filled floats concentrate oil at the apex for skimming
  • Compatible with skimmers such as Octopus for continuous recovery
  • Eliminates head wave and planing issues during tow

Nearshore Booms: For ports, harbors, ponds, and rapid-response units.

TROILBOOM is a lightweight fence boom for rapid deployment, no power packs or air blowers required.

Key features

  • Deploy 200 meters in under 5 minutes, no power packs or air blowers required.
  • Store up to 400 meters on a single reel for instant readiness.
  • Symmetrical closed-cell foam floats allow TROILBOOM to be wound onto reels or packed into racks, containers, or bags.
  • Bright orange PVC/Nitrile-coated woven polyester with reinforced webbing for added tensile strength.
  • Handles every ~1 meter along the top for safe, efficient handling.
  • Internal fiberglass rods keep the skirt upright during towing.
  • Smooth profile for easy post-incident cleaning.
  • Optional PU (Polyurethane) fabric for increased durability.
  • Highly flexible construction that closely follows wave movements for optimal containment. 

Model Range & Reel Recommendations

Choose the TROILBOOM model that fits your operation, with reel guidance tailored to each use case:

  • GP450 – Compact, rapid-response boom
    • Ideal for manual handling and quick strike teams.
    • Reel recommendation: If a reel is desired, use a manual reel (hand-cranked) to keep the system lightweight and field-friendly.
  • GP750 – Medium-duty boom for routine port & harbor operations
    • Reel recommendation: Pair with a eletric reel for faster deployment/retrieval and reduced crew workload
  • GP900 – Heavy-duty boom for larger areas and extended operations
    • Reel recommendation: electric reel recommended for higher boom lengths and frequent use.
  • GP1100 – High-capacity boom for maximum efficiency in demanding conditions
    • Reel recommendation: electric is strongly recommended to handle the boom’s size and to maximize turnaround speed.

GlobeBoom: Superior Fence Boom for Long-Term Containment

A reel-storable fence boom for either rapid deployment or long-term installation, in ports, rivers, industrial basins, and golf course water hazards (seasonal). 

Key features:

  • HDPE hemi-spherical floats, abrasion and crush resistant, mounted on both sides for stability
  • Responds to short-period waves; avoids planing failures common in square-float designs
  • No power packs, inflators, or reels required for deployment
  • Smooth profile for easy cleaning and maintenance

RO-FENCE:  Industrial Oil Booms 

A rigid buoyancy boom for long-term deployment in protected and inland waters, ports, harbors, and industrial basins. 

Key features:

  • Rugged Construction for long-term reliability
  • Impact and abrasion-resistant HD Polyethylene floats
  • Corrosion-resistant fittings for harsh marine conditions
  • Common float design across all sizes for simplified spare parts
  • Floats can be unbolted for cleaning or replaced individually
  • Anchor eyebolts at intervals or end connectors for secure positioning 

Models: RO-FENCE 600, RO-FENCE 900 (shared float design across both)

Mesh Boom - Beach Protection

DESMI Mesh Boom A mesh-grid boom for sargassum control, letting water and wind pass through while retaining seaweed. 

Key features:

  • Mesh tensile strength: 53 kN / 12,000 lbs
  • Polyester filament yarn grid, not a net
  • Foam-filled HDPE floats (no polystyrene), 36 cm / 14" diameter
  • Cast iron ballast weights with stainless steel bolts and nuts
  • Aluminium slide ASTM (F 962) end connectors for quick removal
  • Standard section length: 15 m / 50 ft (custom lengths available)

Dimensions: 105 cm / 42" overall height, 75 cm / 30" draft, 30.5 cm / 12" freeboard

A-bloom

A-Boom

A-Boom is designed as a rapid deployment, first-response oil spill containment boom for protected waters. It is intended for temporary emergency use and training purposes.

Developed by DESMI Ro-Clean, A-BOOM is an economical fence boom designed for quick deployment during oil spill emergencies. Its lightweight construction enables easy handling by one or two operators, allowing rapid response when protecting sensitive environments and water resources. 

Manufactured from UV-resistant and oil-resistant materials, A-BOOM combines effective containment performance with environmental responsibility. Unlike many conventional booms, A-BOOM can be thermally disposed of at the end of its service life, with only the ballast chain requiring removal.

Note: A-BOOM is not suitable for long-term deployment. The product is specifically designed for first-aid spill response situations and performs exceptionally well as a training boom for spill response exercises and preparedness programs
