Impact & abrasion protection

What is impact and abrasion protection?
- Impact and abrasion protection helps protect subsea cables, umbilicals, pipelines, risers, hoses and other infrastructure from physical damage. Different protection systems are designed for specific applications and can help manage risks associated with contact, movement, installation and the subsea environment.
Why is impact and abrasion protection important subsea?
- Subsea infrastructure can be exposed to contact with other equipment, structures or lines, as well as movement against surrounding surfaces. Appropriate protection can help reduce the risk of damage and support the long-term integrity of critical assets.
What is Uraduct® used for?
- Uraduct® is a modular protection system designed to protect subsea cables, umbilicals, pipelines and hoses from impact and abrasion. Different configurations within the Uraduct® range provide additional functionality for specific applications, including ballast, buoyancy and retrofit riser protection.
What is the difference between Uraduct® Ballast and Uraduct® Buoyant?
- Uraduct® Ballast is designed to provide additional submerged weight where increased seabed stability is required. Uraduct® Buoyant provides impact and abrasion protection while reducing the weight of a subsea line, making it suitable for applications such as cable crossings where excess weight could damage an existing line.
Can existing subsea infrastructure be protected or retrofitted?
- Yes. Some solutions are designed specifically for retrofit applications. Uraduct® RRS, for example, provides impact and abrasion protection for risers and multiple lines attached to platform legs, offering an alternative where cable entry through existing J-tubes or I-tubes is not possible.
Are impact and abrasion protection systems suitable for different types of subsea infrastructure?
- Yes. Solutions within the product family can be used across applications involving subsea cables, power and fibre-optic cables, umbilicals, flowlines, hoses, risers and pipelines. Product selection depends on the specific asset and operating conditions.
Can Uraduct® be used outside the offshore industry?
- Yes. While Uraduct® is widely used for subsea impact and abrasion protection, its protective properties can also be applied in other challenging environments. For example, Uraduct® has been supplied for mining applications to help protect critical infrastructure from the effects of blasting.
How do I select the right protection solution?
- The appropriate solution depends on factors such as the type and size of the asset, the source of potential impact or abrasion, installation method, surrounding infrastructure and environmental conditions. An application-specific assessment can help identify the most suitable protection system.
