DESMI Oilfence Long-Term Oil Containment Barrier

Oilfence long-term oil containment barrier has been in production for over 30 years. Much of the original boom is still in service. This unique design is extremely stable and tough due to the combination of extra-wide outrigger floats and urethane-impregnated, high tensile-strength barrier fabric.

Available in four sizes to suit the customer’s need, this tough boom is ideal for fixed deployments and high-energy wind and wave environments. The larger sizes are able to provide an imposing “line-in-the-water”, and can support lights, signs and conventional physical security barrier elements above the surface, together with barriers or netting systems sub-surface.

An Oilfence long-term oil containment barrier delivers outstanding stability, buoyancy and corrosion resistance, plus easy installation and routine maintenance. One of the unique features of this boom is the ability to operate without a traditional ballast. The top half (freeboard) is the same as the bottom half (skirt). Oilfence has many applications worldwide including; offshore production platforms, exploratory rigs, marine terminals, sea water intakes, oil jetties, settling ponds and many coastal applications.

  • High stability in waves, wind and tidal currents
    An Oilfence long-term oil containment barrier deliver outstanding stability, even in high currents or severe offshore applications, because of their unique, large ratio of flotation span to height. This ratio is possible, because the Oilfence system uses extra-wide outrigger flotation to support its high-tensile strength barrier fabric. Stiff, injection molded vertical stabilizers reduce bowing in currents and maintain the barrier against splash-over. The floats are mounted on axles and can fully rotate thus minimising forces on the boom fabric.
  • Corrosion-free performance:
    From durable, synthetic plastic components Oilfence installations reliably deliver many years of continuous and sustained service. Oilfence materials are advanced synthetics that are both strong and highly resistant to degradation from salt water, ultra-violet light, ozone and abrasion. Oilfence stabilisers and flotation components are moulded of high-strength plastics, resins and fiber glass. The barrier fabric is woven polyester that is impregnated with polyurethane for very high resistance to both abrasion and tear. All metallic parts are stainless steel.
  • Ease of installation and towing:
    With quick secure, unisex end connectors, Oilfence containment is simple and fast to install. Sections connect securely without tools. The polymer, unisex end connectors join with a patented double quick lock that latches with twin stainless steel rods. A “supertough” nylon handle at the top and bottom of each stabiliser allows effective tie-off and handling, plus secure storage bundling.
  • Simple routine maintenance:
    The fully symmetrical design of Oilfence sections, with equal freeboard and draft, greatly simplifies routine maintenance. When cleaning is needed, each section is simply turned over. The sea growth can then die and fall off. All Oilfence surfaces are smooth and non-porous, so they are readily cleaned in position with pressure washers
