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.
Claims22
A subsea control system testing skid comprising:
- at least one marinized testing module mounted on the testing skid, the testing module selected from one or more of electrical, optical and fluidic conduit testing modules;
- at least one data logger(s) are mounted on the skid to record the measurements taken via the testing module;
- and
- at least one flying lead or hot stab adapted for connection between the testing module and a termination assembly on a subsea control system.
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 one or more testing or service modules together with one or more respective testing or service data loggers mounted on the skid;
- 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, and
- logging the conduct of the electrical, optical and/or fluidic conduit testing on the one or more subsea data loggers.
A subsea control system testing skid comprising:
- a subsea testing skid frame having a ROV, SUW or AUV interface plate;
- a plurality of marinized testing modules mounted on the subsea testing skid including at least one marinized fluidic testing module and at least one additional marinized testing module, the additional marinized testing module selected from one or more of an electrical and an optical testing module;
- at least one data logger mounted on the skid in operable communication with each of the plurality of marinized testing modules and adapted to record measurements taken subsea via the testing modules;
- and
- at least one flying lead or hot stab adapted for connection between the testing modules and a termination assembly on a subsea control system.
