Divers and ROV’s require clear identification of the valve they are looking at subsea, and more importantly the operational (‘open’ or ‘closed’) position. AQUASIGN can provide long term, highly visible signage that provides easy identification of both the valve and the position.

Typical Substrates

Valves identification markings are typically applied around the valve body or stem.  For some applications, additional supporting plates are manufactured.  Aquasign markers can be fixed to various surfaces – coated steel / stainless steel and plastics.  If surface space is limited, Aquasign tags can be used.

Typical Marker Design

The flexible nature of our Aquasign subsea markers ensure fixings over both flat and tubular applications.  Whilst there are limited industry standards specific to subsea indentification, typical text heights are provided below:

  • Identification (valve no.s) 50-100mm
  • Positioning (open/closed) 15-100mm

Fixing Recommendations – ONSHORE

For installation on the surface, prior to deployment, AQUASIGN offer both adhesive and mechanical fixings to suit any application:

Adhesive: KISS®*/  Mechanical: Bolted  /  Shield™ Tags using Cable Ties

*Recommendations are made on the attaching surface, visit our Knowledge Hub for our Substrate Guide for further details.

Fixing Recommendations – OFFSHORE

Offshore or ‘retrofit’ solutions will be dependent on project location and installation method i.e.:

Diver: Magnet*  /  Subsea Adhesive,   /  Cable Tie**  / ROV: Magnet*

*Magnet use is dependent on size/space available

**Cable ties for equipment already subsea can only be installed by divers

Regardless of the valve location, size and spec, AQUASIGN can provide long term, antifouling markings designed around the specification of your subsea equipment.

Don’t just take our word for it, a Purchasing Manager – USA for the Vashishta, India project gave us this review:

‘We are satisfied with the level of customer service and quality of products received. The KISS® self-adhesive markers supplied met the requirements of the project and were very easy to install.
