Pre-commissioning Subsea Umbilical and Cable Pre-commissioning

Subsea Umbilical and Cable Pre-commissioning

Umbilical pre-commissioning is a suite of tests performed from a host facility, usually an offshore platform or a Floating Production, Storage and Offloading (FPSO) vessel, to confirm mechanical and structural integrity of newly installed umbilical(s) and associated in-field electrical, hydraulic and, in some instances, fibre optic functional connections. 

These functional connections are made through the use of dedicated electrical, hydraulic and optical flying leads which allow conveyance of hydraulic power, communication and production chemicals / service fluids via umbilicals connected between a host facility and Subsea Production System (SPS).

Offshore Energy performs pre-commissioning testing in accordance with current ISO standards for Petroleum and Natural Gas Industries - Design and Operation of Subsea Production Systems, Part 5: Subsea Umbilicals (13628-5).

System design and complexity dictate pre-commissioning testing. It may be beneficial to perform sequential testing using a systematic approach, allowing earlier detection and diagnosis of any faults, their type and location. As well as testing, umbilical integrity checking and monitoring can also be performed throughout transportation and installation phases, as well as post installation.
