CABLE PROTECTION


HR WALLINGFORD


IS INTERNATIONALLY RECOGNISED AS AN AUTHORITY ON SEABED PROCESSES


Further, in the case of rock armour- based solutions, the implementation of standard designs can result in cable damage or inadvertently create increased disturbance to the flow and significant secondary scouring, leading to the exposure of cables and failure of the rock protection.


OTHER RISK AREAS


Other areas of potential high risk occur at locations where cables are crossing other previously installed seabed infrastructure, such as other submarine cables. Whilst poor design of protection measures for cable-crossing locations can result in some of the issues previously mentioned, careful consideration during the route selection stage can potentially avoid some of these problems by choosing,


for example, to cross at a point where the cable can be aligned along the flow direction, rather than perpendicular to it. As more seabed located infrastructure is installed, the requirement to manage potential risks will increase.


JOINED-UP APPROACH


Richard Whitehouse, Chief Technical Director, HR Wallingford, says: “It is important to have a joined-up approach to the design of both foundation and cable systems, rather than dealing with these as two separate packages. This ensures that appropriate remedial solutions are designed where problems have occurred, and ensures the correct evaluation of scour risk for new developments is made, to pre-empt possible problems before they arise.”


MARINE SCOUR COURSE


The company has developed a new two-day Marine Scour Course which introduces analysis procedures for assessing risk at marine structures, as well as the appropriate use of scour countermeasures, through a combination of theory, practical sessions and classroom discussions. Two of the sessions will focus on pipelines and cables specifically.
