A continuous operating protection system called COPS
The continuous operating protection system called COPS is a diverless solution to achieve the stabilization and protection of subsea pipelines and cables: the system is based on the use of a continuous fabric form work mattress which is spread on the sea bed over the pipeline or cable to be protected by a remotely controlled underwater crawler and simultaneously filled with cement grout. The method has been successfully used in the GULLFAKS field where about 3.6 km of grout mattresses having a cross section of 2 meters by 0.2 meters have been laid. The performances of the system are presented as well as a trade off comparison with the other stabilization and protection methods currently used: burying, rock dumping or placement of covers.
