Abstract
An aspect encompasses a method of testing a subsea umbilical where a first portion of testing is performed on the subsea umbilical, the testing comprising hydraulic testing and at least one of electrical or optical testing, and a second portion of the testing is performed independent of a diver or an ROV.
Claims20
A method of testing a subsea control umbilical, comprising:
- with an umbilical testing skid residing subsea and coupled to communicate hydraulically with the subsea control umbilical and at least one of electrically or optically with the subsea control umbilical,
- initiating at least one of electric or optical testing on the subsea control umbilical;
- initiating hydraulic testing on the subsea control umbilical;
- and
- performing substantially the remainder of the hydraulic testing with the testing skid not coupled to an ROV.
2 more elements
A system for testing a subsea control umbilical, comprising:
- a test skid comprising:
- a hydraulic testing unit for hydraulic testing the subsea control umbilical;
- an electrical testing unit for performing electrical testing on the subsea control umbilical;
- an optical fiber testing unit for performing optical fiber testing on the subsea control umbilical;
- an umbilical coupling in communication with the hydraulic testing unit, the electrical testing unit, and the optical fiber testing unit for communicating, apart from an ROV, between the hydraulic testing unit, the electrical testing unit, and the optical fiber testing unit and a human machine interface;
- and
- a test lead coupling for coupling the hydraulic testing unit, the electrical testing unit, and the optical fiber testing unit to the subsea control umbilical being tested.
