Animation of the pipeline protection activity mattress installation. In most parts of the world where oil and gas production takes place, there are many existing pipelines and cables on the seabed that must be crossed when installing a new pipeline. To prevent any damage to these existing pipelines and cables, crossing preparations must be performed before a new pipeline is installed.
Protection is provided by mattresses, consisting of concrete blocks connected by steel or synthetic material. The concrete blocks are covered with special pads to prevent the pipeline from being damaged. Since the crossing protrudes above the level of the seabed, it is covered either by rocks (rock dumping) or by additional mattresses for protection. Allseas’ support vessels are able to install concrete mattresses using their remotely controlled subsea installation frame and her ROV-operated mattress installation frame.
