Scope
A major independent oil and gas company engaged ICR to assist with the decommissioning of three 6” hydrocarbon lines at its onshore gas-processing and reception terminal in North East England, United Kingdom.
With a long-standing relationship with ICR, the customer recognised that ICR’s 100% cold-work technology, Quickflange™, was the optimal solution for this scope providing a far safer and significantly faster installation method than any traditional alternative.
Solution
After reviewing the line conditions, our technical team determined that three 6” Sch40 150# Quickflange™ installations were required. An initial engineering assessment identified potential space constraints that could impact execution, particularly around the use of a standard clamshell cutter for the necessary cold cuts.
A detailed review of site information and updated scope modelling confirmed that sufficient access was available and that a standard clamshell cutter could be used without issue. With accessibility verified, the client was assured that the installations could proceed efficiently using the Quickflange™ solution.
With all technical considerations addressed, ICR mobilised an experienced technician along with the required cutting, installation, and testing equipment to safely and effectively deliver the work on site.
Results
Each installation underwent full QA/QC testing, confirming the integrity and reliability of the lines. The work progressed smoothly across just two shifts, demonstrating both the efficiency of the Quickflange™ solution and the expertise of the onsite team.
The project was completed without the need for any hot work, delivering a safe, cost-effective, and low-risk outcome for the customer. The redundant lines were successfully decommissioned and sealed with blind flanges, ensuring permanent isolation and long-term assurance.
