Aquasign subsea markers are used to provide clear, long term signage for three main functions;
The flexibility in design and extensive fixing range means Aquasign can be used on every type of subsea equipment from the smallest hoses and valves to platform leg and vessel hulls.
Our unique anti-fouling system combines a hydrophobic silicone surface and a non-toxic proprietary oil designed to prevent marine growth from adhering to the marker.
The oil is released from an internal reservoir over time, ensuring that the marker continues to work effectively even if the marker’s surface develops imperfections over time.
Aquasign anti-fouling markers are ideal for use on assets in shallow water. Cheaper alternatives, such as plastics and vinyl, can foul extremely quickly in shallow depths. They may even need to be cleaned before your asset’s first inspection – a costly and time-consuming operation involving a trained diver.
