ICR Integrity (ICR) (Aberdeen, United Kingdom), a leading provider of integrated maintenance, repair, and production solutions for the offshore oil and gas, power, defense, nuclear, utilities, and renewables industries, recently completed a crucial scope of work for Doosan Babcock (Crawley, United Kingdom) on the Forties Pipeline System (FPS) shutdown project at the Cruden Bay Booster Station in Northeast Scotland.
By utilizing ICR’s multi-skilled team, total headcount was reduced by six, according to the provider. In turn, this resulted in time and cost savings for the project. The three-week shutdown, intended to ensure reliability to 2040, supported the removal and reinstatement of the main valves and piping from the sealine receiver from the Forties field through to the new, aboveground piping system and pig launcher at the land line.
A key project for ICR, the regeneration works at Cruden Bay represents a key part in the FPS shutdown. It required close planning with the Doosan Babcock site construction team for several months during the construction phase of the project, all prior to embedding a team for the site outage.
The ICR team was responsible for bolt tensioning, torquing, and flange management work for the aboveground large-bore piping and valves. This led to a 14-person multi-skilled team working 12-h shifts, often day and night and back-to-back, during the shutdown to complete the critical path works. The team also completed pre-outage hot bolting, outage bolting operations, pipe cutting for the removal of the redundant piping and land-line launcher, line boring on critical path spool work, and the reinstating of all large bore spools and valves.
“The final completion of the leak testing package gave the site a 100% pass rate, meaning the sealine could be de-isolated to enable offshore to start pumping again,” says Shane Gregory, ICR’s business development manager.
