Guides, clamps and seals

What are guides, clamps and seals used for?
- Guides, clamps and seals perform different functions across subsea and offshore applications. They can help position and support cables, umbilicals, pipelines and risers, secure flexible lines, manage connections and retain fluids or grout where sealing is required.
What types of guides and clamps does AIS offer?
- The range includes centralisers, piggyback systems, tether clamps and tether bases, alongside J-tube products. These solutions address applications including cable and pipeline support, line positioning, seabed restraint and installation.
What are centralisers used for?
- Centralisers help keep cables, umbilicals, pipelines or combinations of lines centred within I-tubes, J-tubes, tunnels and larger-diameter pipes. They can reduce contact with the surrounding structure and therefore help minimise abrasion during operation.
What is a piggyback system?
- A piggyback system allows a smaller service line, cable or umbilical to be secured to a main pipeline during installation. The system provides support between the surface and seabed while maintaining the secondary line in position.
What are tether clamps used for?
- Tether clamps are used to maintain the position of dynamic flexible pipes, umbilicals or cables. They can be connected to a seabed anchor or tether base and are designed to accommodate significant axial and tether loads. Some configurations also incorporate 360-degree rotation to help manage torsional loads.
What are J-tube seals used for?
- J-tube seals are designed to retain corrosion inhibitor within the annulus between a host line and the J-tube bore. They use an interference fit between the seal elements and surrounding surfaces, with no subsea activation required.
What are grout seals used for?
- AIS grout seals are custom-designed seals used to retain liquid grout during the final operation that secures the connection between a monopile foundation and transition piece. They can be manufactured in large diameters and optionally fibre reinforced for applications requiring increased strength.
Can guides, clamps and seals be customised?
- Yes. Many of these products are designed around the specific geometry, loading, installation method and operating environment of each project. Bespoke configurations are available across the range, including tether systems, J-tube seals and grout seals.
