ABSTRACT:
The method of protecting two subsea pipelines which cross each other in a subsea environment from damaging one another when subsea currents slide the upper pipeline along the upper surface of the lower pipeline by providing roller around the upper pipeline and rollers around the lower pipeline which are connected together by a rotatable connection which allows the sets of roller to match the angle of the pipeline.
