Neoprene Oil Boom

The Neoprene Boom is a very flexible, heavy duty type oil boom for containment of oil especially for offshore and Arctic conditions, or for permanent installations in harbors. It is robust and durable, but light and very easy to deploy rapidly.

The unique design coupled with the light, but extremely durable vulcanized neoprene material, makes it possible to store up to 300 m (984 ft) on one compact storage reel. When the boom of model Autoboom is deployed from the reel, it is automatically inflated from a single air source at the end of the boom, which ensures rapid and safe deployment. Retrieval is also efficient, due to easy deflation onto the storage reel.

Upon inflation, the patented internal design automatically separates the cylindrical floatation chambers. Each Individual Buoyancy Chamber is isolated. If one air chamber should get damaged or deflated, adjacent chambers will not be affected and will remain inflated.

The neoprene boom can also be supplied with single air chamber inflation


  • single-point air inflation for simple and rapid deployment or chamber by chamber inflation
  • compact storage volume
  • durable fabric
  • excellent wave following performance
  • high buoyancy to weight ratio
  • requires only one operator
  • safe to use and deploy – low pressure air source

Mk E Floating Baffle System

The Mk E Floating Baffle System is ideal for use in wastewater lagoons and industrial reservoirs. The Mk E baffle can be used to divide the basin into cells to provide e.g. progressive treatment of water and waste by creating a serpentine flow pattern. By increasing the retention time, the baffle systems allow solids and other contaminants to settle to the bottom of the lagoon, reservoir or tank, before the water leaves through the effluent.

The Mk E baffle is constructed of either heavy duty woven polyester coated with XR-5 geomembrane material or alternatively PVC coated polyester fabric (625 g / 22oz) that is highly resistant to chemicals typically found in waste and industrial applications, encapsulated solid closed cell polyethylene foam flotation, elastomeric coated top tension and a hot dipped galvanized chain that can be substituted with steel bars as ballast for the fabric skirt. All anchoring and connector hardware is included.

The durable construction has marine growth inhibitors and is UV resistant. The baffle is low maintenance and can withstand the impacts of freezing temperatures, strong winds and currents.

Technical Specifications: Benefits:
  • Wastewater and industrial applications
  • Durable, ideal for permanent installations
  • Marine growth inhibitors, UV resistant
  • Withstands winds and currents from aerators
  • Long service life
  • Low maintenance

The Silt Curtain

The Silt Curtain is specially designed to be used in conjunction with a conventional containment boom when the problem is the presence of sediments drifting in the water, caused by dredging or other type of construction work in a port, harbor, river or lake.

These materials are often drifting at a greater depth than usually covered by the skirt of a containment boom.

The silt curtain has a 2000 mm (alternatively 4000 mm or 6000 mm) high skirt and comes in stretches of 25 m. It is made of a polypropylene fabric reinforced with a highly resistant PET fibre, which due to its drainage capacity allows water to pass through while efficiently retaining the sediments.

When silt curtains are used to enclose open-water pipeline disposal operations, the vast majority (95 % or more) of the sediments descends to the bottom of the disposal area where it forms a fluid mud layer. The remaining 5 % or less of the sediments is responsible for the turbidity in the water column.

The silt curtain is connected to the oil boom ballast chain with shackles. The stretches of silt curtain are connected to each other also using shackles, while the boom itself is connected up using its normal connectors (ASTM, Norwegian, UNICON, etc.).

Inflatable PU boom

Inflatable PU Boom | Wales | Zwanny Ltd The boom, which has internal replaceable buoyancy chambers, is particularly robust, giving a long service life with a minimum of maintenance.

The excellent buoyancy and wave-following characteristics are achieved by way of large, cylindrical buoyancy chambers, slightly separated from each other, giving the boom flexibility when riding the waves.

Booms are entirely manufactured (external fabric and internal floatation chambers) from heavy duty PVC-coated polyester fabric. This fabric is both strong and lightweight, giving rise to extremely robust and high quality booms. It is also highly resistant to oil, chemicals, all weather conditions and UV light.

All seams and unions are high frequency welded, maintaining the excellent mechanical properties of the fabric, and ensuring air and water tightness, and a uniform appearance.

And the simple design, with large, flat, parallel surfaces, makes cleaning the boom an easy task. All models are equipped with a high tensile strength ballast chain in a pocket at the base of the skirt.

Permanent Containment Booms

Permanent Containment Booms | Wales | Zwanny Ltd Permanent Containment Booms are heavy-duty booms with high-density polyethylene floats.

he boom is particularly robust and is made to give a particularly long service life in installations where booms are used frequently and on a permanent basis.

Boom Design

A boom with a heavy PU or PVC vertical barrier fabric and symmetrically placed foam-filled high-density polyethylene floats.

The two halves of the floats are bolted together trapping the barrier fabric in between.

This gives rise to a particularly heavy-duty construction which is easy to maintain and repair on site. Most of the forces on the boom are absorbed by the ballast chain, which is shackled on to the lower part of the skirt. The ballast chain is connected between sections with “split-links” made from hot-dip galvanised steel.

Each section is fitted with marine grade aluminium ASTM connectors. Tools are not required to connect the sections together. Alternatively, Unicon or Norwegian type connectors may be delivered.

Beach Sealing boom

Beach Sealing Boom | Wales | Zwanny Ltd Beach sealing booms provide an excellent seal against the shoreline in tidal areas: strong currents, areas exposed to strong tidal movements, rivers, estuaries and sheltered waters.

Boom Construction

Beach sealing booms have a triangular cross-section with a continuous air-filled tube above
and two water-filled ballast chambers below.

The air filled tube has three internal buoyancy chambers. Thus, the boom floats as a conventional boom when working in waters with sufficient depth, and by effect of the weight of the ballast and its flexibility, seals the foreshore in low tide conditions.

Beach sealing booms are manufactured from premium quality PVC-coated polyester. This
material is both strong and light, and gives rise to a hard-wearing and virtually maintenance-free product.

On the underside of the boom there is a replaceable fabric, protecting the boom from wear and tear when working against abrasive surfaces. Each section is fitted with marine grade aluminium ASTM end connectors making the use of tools for connecting the sections together unnecessary.
