Subsea markers are passive identification markers used under water to identify equipment . As sub sea equipment may be covered in underwater growth like seaweed, kelp and algae, special non-fouling materials are necessary for equipment marking to ensure these are readable even after prolonged periods of submergence. How it works Subsea markers are made from a durable rubber which has been manufactured to include synthetic oils. The oil is evenly distributed through the material and gives the material excellent hydrophobic properties. The hydrophobic properties of the material prevent marine growth from attaching to the surface of the marker making it readable even after several years of submersion under water. Applications Subsea markers are typically used to identify the following equipment and the equipment placed on them: valves Christmas trees manifolds pipelines caps and connectors chemical injection/distribution units pressure caps and connectors Alternative uses are for marking fish like sharks and whales. Subsea markers could also be used in sewage systems or to mark shipwrecks for divers. External links Aquasign
