The cover (20) includes a deformable jacket (40), intended to be placed around the submerged element.

The deformable jacket (40) has an internal volume (44).

The cover (20) comprises: a plurality of insulating elements (46) arranged in the internal volume (44), able to move freely relative to one another; at least one opening (48) for selective access to the internal volume (44) through the deformable jacket (40), for allowing the internal volume (44) to be flooded by a liquid during the deployment of the cover (20) towards the submerged element, and for allowing suction of the liquid contained in the internal volume (44) during the application of the cover (20) on the submerged element.

A system for the repair or reinforcement of a pipeline includes a casing having a dimension to envelope a damaged portion of the pipeline, such that a space is defined between an inner surface of the casing and an outer periphery of the pipeline. An injection port is positioned along the casing and is in selective communication with the space. A cap assembly is frictionally attached to the casing and the pipeline, after which time an injectable material is selectively injected through the injection port until filling a substantial entirety of the space.
