HEAVY DUTY OPEN WATER FLOATING CURTAINS 

Our sea curtain system provides a multipurpose float assembly for use with a range of skirt configurations from Heavy duty oil containment booms to heavy duty high integrity silt curtains. The individual float logs are 2m long and 300mm high foam filled HDPE through bolted reinforcing belting on the skirt assemblies. They are able to sustain hits from small vessels and are easily changed when required. In addition to use in open water conditions the float system is suitable for use on:

bulletPermanent installations for oil and debris containment/diversion at plant outfalls and intakes
bulletHeavy baffles for sewage and water treatment plants and oil field dewatering ponds
bulletPermanent installations around sensitive ship discharge and loading operations
bulletFrequent deployment around ship bunkering and transfer operations
bulletStorm water outfall and weed containment netting booms
bulletToxic algae trawls using flow through skirts
bulletHigh durability baffle systems

As a float assembly for our high integrity sediment curtains they are routinely deployed in the harshest conditions. The curtain pictured below is deployed in an southerly exposed location on Botany Bay Australia and experiences winds to 100kph and short interval wind generated waves up to 1.5m.

We fabricate components to optimise installations pictured is a fabricated  chaffing bar installed over wharf edge Our equipment inventory includes excavators for moving curtains on barges, deploying mooring systems, piling and installing shore anchors Ballast moored curtain is simultaneously deployed from a barge together with a 90mm stud link chain ballast mooring assembly

These have between 5000kgf and 10000kgf of holding capacity depending on bottom type
