Curtain and Slit Booms
Curtain Boom Overview
Curtain booms can be used in rivers, estuaries, harbours or coastlines (slight sea). Flotation is provided by thick foam blocks with closed cells which are 80cm to 1m long to provide flexibility. Curtain booms have a higher buoyancy weight ratio than Fence booms, offering a better response to waves when being towed. Curtain booms can be stored on reels or rack systems.
Slit Boom Overview
By changing the “skirt” (draft) of the boom to a geotextile it can be used to contain waste such as gravel, sediment etc. (2 to 10m depth) Contact us to discuss your specific application.

Air Booms
Overview
Air booms are ideal for deploying from spill responses vessels, where curtain booms would be bulky and impractical to use. Volume is reduced as flotation is via inflatable chambers from 5m to 25m. Typically used on open water where there could be rough sea and, as a consequence, a high buoyancy to weight ratio is important to offer a better response to waves when being towed. Inflation is achieved by manual, electrical or thermic blowers.
Features
- Compact in storage
- PVC, PU (Polyurethane), Neoprene options available
- Steel galvanized chain ballast protected by a flange
- ASTM junction with fast connectors
Accessories
- Reels (120m to 600m capacity)

Self-Inflating Booms
Overview
Self-inflating booms are ideal for deploying from spill responses vessels, where curtain booms would be bulky and impractical. Volume is reduced as flotation is via inflatable chambers from 5m to 25m. Typically used on open water where there could be rough sea and, as a consequence, a high buoyancy to weight ratio is important to offer a better response to waves when being towed. Self-inflating booms rely on springs/coils inside the structure of the boom that are compressed in storage and the action of deployment draws air into the boom via a one-way valve.

Tidal Booms
Overview
Tidal booms with a ballast chamber (water filled) are designed for shallow water or where you need containment to start from the shore (connect to the shore line with permanent or curtain booms floating in the water).

Reels & Containers Overview
We offer a full range of reels from 1 to 5m which can be powered by hydraulics, electrics (220v or 380v tri) or manually. To aid the correct storage of your equipment we offer 20ft or 40ft ISO containers which can be outfitted with reels or storage racks for your booms and provide storage for tanks, skimmers, pumps, power packs etc. These dedicated stores provide security for expensive equipment and make it easy to transport it all together minimizing the risk of damage in transit.
Rack Overview
This rack (hot dip galvanised steel) is designed to aid the rapid deployment of booms and protect them when not in use. Fitted with transport restraints to minimise the risk of damage in transit, the unit is also fitted with fork pockets for easy movement by fork lift truck. Racks can be stacked up to 3 high to reduce the storage footprint.
Portable Air BBlower Overview
- A practical way to inflate booms in any location
- Powered by a 43cc, 2.4 hp two-stroke oil engine
- Weighs 9.5kg
ASTM Wire Connector Overview
Move or secure booms by connecting the system to the ASTM connection (extruded aluminium) on the boom. Manufactured with 1500kgf/5cm strength and stainless steel cables.
Skimmers
Weir Skimmer Overview
Weir skimmers work by allowing the oil floating on the surface of the water to flow over a weir (height is selfadjustable to maintain ration of oil to water collected) and be collected for disposal. A submersible pump sits underneath to transfer the collected oil.
D-Type Skimmer Overview
This type of skimmer sits at the head of a submersible pump and is used to skim across the surface of the water, making it ideal for collecting thick, viscous layers of hydrocarbons in “still” waters (lakes, rivers, harbours etc)
Brush Skimmer Overview
Brush skimmers comprise of 1, 2 or 4 side-by-side banks of brushes with the “bristles” made of polypropylene to ensure a strong resistance to chemical products and at the same time only absorbing a small amount of water. Each brush row is powered by its own hydraulic engine and the skimmed hydrocarbons are pumped to a storage tank via an onboard pumping system. This type of skimmer is ideal for use with high-viscosity hydrocarbons.
Disk Skimmer Overview
Disc skimmer comprise of 1, 2 or 4 side-by-side oleophilic rows of discs (PVC, aluminium or steel) which collect the hydrocarbons inside the skimmer and each row of discs is powered by its own hydraulic engine. The hydrocarbons stick to the disks which, as they rotate interact with flexible scrappers to remove the hydrocarbons. The collected hydrocarbons are then pumped to a storage tank. This type of skimmer is ideal for use with low and mediumviscosity hydrocarbons.
Drum Skimmer Overview
Drum skimmers comprise of 1, 2 or 4 side-by-side drum(s) powered by their own engine. As the drum(s) rotate the hydrocarbons stick to the surface and are scrapped off by flexible scrappers located on the sides of the drum(s). The collected hydrocarbons are then pumped to a storage tank. This skimmer is ideal for low and medium viscosity hydrocarbons.
Multi Function Skimmer Overview
Multi-functions skimmers are a combination of three different styles of skimmer (brushes, discs and drums) designed to collect varying types of hydrocarbon.
