  • Patent number: 8430168
    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.

  • Patent number: 7708839
    Abstract: The present invention is directed to a pig receiver used in a dewatering method for subsea pipelines. In the dewatering method a pig is placed in one end of the pipeline filled with water and a compressed gas is introduced behind the pig; in addition the water and pig are drawn by a subsea pump operated by a submersible vehicle (SV) operating near the sea floor to a pig receiver of the present invention. A feature of the pig receiver is a gas sensor that shuts the pump off when gas enters the receiver to prevent a gas (vapor) lock of the pump.

  • Patent number: 7281880
    Abstract: The present invention is directed to a method for completing the commissioning of a subsea pipeline by purging with a compressed gas to dewater and dry the line wherein the operation is done on the seabed. More specifically, the method is carried out with a subsea vechicle (hereinafter “SV”) that powers pumps located on the seabed or are carried by the SV to inject/remove chemical, dewater, and dry, the pipeline. The present invention may be part of the commissioning of a new or old pipeline or a new portion of a pipeline in which a purging of the line with a compressed gas and drying of the line is required. After commissioning, product flows through the pipeline.

  • Patent number: 6840088
    Abstract: The present invention is directed to a pumping skid that may comprise a skid structure, a high volume pump, a battery of high-pressure pumps, a chemical water treating tank, a docking plate and a bouyancy compensator. More specifically, the skid is carried by a subsea vechicle (hereinafter “SV”) that provides the power to the pumps located on the skid to inject water/chemical, pressurize the water, dewater, and dry, the pipeline. The present invention may be part of the commissioning of a new or old pipeline or a new portion of a pipeline in which a purging of the line with a compressed gas and drying of the line is required. After commissioning, product flows through the pipeline.
