Abstract: A method of remediation of a wet buckled pipeline uses a Submersible Vehicle (SV), Autonomous Underwater Vehicle (AUV), or Remote Operated Vehicle (ROV) and includes the steps of retaining an end of the buckled pipeline; cutting the buckled pipeline underwater below a damaged section of the buckled pipeline; attaching a termination to the cut end of the buckled pipeline; connecting a hydraulic pump to the termination; and running the pump to pull water out of the pipeline.

Abstract: Apparatus and methods are described for subsea pipeline servicing, including line-pack testing, physical integrity testing, recovery of damaged sections of pipelines, and product removal from subsea structures. In one embodiment of the invention, a subsea pipeline service skid is provided including at least one sample collection bladder affixed to the skid and in fluid communication with a skid mounted pump dimensioned to pull a sample from the subsea pipeline. In another embodiment, a product removal bladder is provided for removal of the hydrocarbons from a subsea structure. In one embodiment, a method of wet-buckle remediation is provided using a subsea pump to unweight the pipeline.

Abstract: Apparatus and methods are described for subsea pipeline servicing, including dewatering and chemical containment. A subsea pipeline service skid has a containment bladder affixed to the skid and in fluid communication with a skid mounted pump dimensioned to pump fluid from the subsea pipeline. A sensor system at the suction side of the pump detects the presence of seawater, water, chemical agent, or gas so the pump can be operated accordingly. The chemical agent used during dewatering operations of the pipeline is selectively pumped to the containment bladder subsea so the subsea vehicle can independently take the chemical agent to the surface.

Abstract: Apparatus and methods are described for subsea control system testing including one or more of electrical, optical and fluidic conduit testing, wherein the testing is conducted subsea using a subsea testing skid. In one embodiment of the invention a subsea pipeline service skid is provided that includes at least one skid mounted pump dimensioned to deliver from about 3000 to about 20000 p.s.i. of pressure for pressure testing the fluidic conduits to desired pressures. Modular construction of the skid permits customization for testing service of unique subsea control equipment.
