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.

11. A method of testing and service of a subsea control system comprising:
-
transporting a testing and service skid to a subsea control system using a SV, ROV or AUV, wherein the testing and service skid comprises a plurality of testing or service modules operably mounted on the skid together with one or more respective testing or service data loggers operably mounted on the skid and wherein the plurality of testing or service modules include at least one fluidic conduit testing module and at least one additional marinized testing module, the additional marinized testing module selected from one or more of an electrical testing module and an optical testing module, each of the modules configured to test components present on a subsea control system; docking the testing and service skid to a termination assembly on the subsea control system; utilizing one or more of the testing or service modules mounted on the skid to perform one or more of electrical, optical and fluidic conduit testing on the subsea control system while the testing modules are mounted on the testing skid, and logging the conduct of the electrical, optical and/or fluidic conduit testing on the one or more subsea data logger(s). - View Dependent Claims (12, 13, 14, 15, 16)
