Registered Design

The standard specification of Aquasign® subsea markers has successfully been registered in accordance with the Registered Designs Act 1949. There are no equivalents to our Aquasign® subsea marking solution, therefore our Registered Design allows our customers to feel confident that they receive a quality, fit for purpose product, in accordance with their project specification.

An integral part of our Registered Design and way to easily recognise an Aquasign® subsea marker, is the introduction of curved corners aiding the installation process of our Biohesive® 225 sealing bead. For more information, see our KISS®self-adhesive label page.

Bespoke Design

Our silicone based anti-fouling marking systems are flexible, in both design and the fixing solutions available. Manufactured in-house, our subsea markers can be supplied in various colours, sizes and designs – including your company logo!

AQUASIGN recently invested in new cutting technology that also allows us to produce markers of almost any shape, including complete ROV panels – improving the installation process and anti-fouling properties.

Our largest mould used to manufacture Aquasign® markers is 2450mm wide and 990mm high, however for larger requirements the marker can be supplied as multiple components with pre-defined cut lines.
