Pipeline engineering specialist, STATS Group, has completed a six-figure valued pipework maintenance contract on behalf of Dolphin Energy in Qatar.

STATS carried out the planned maintenance on a 36” gas pipeline onboard the DOL-2 platform in the North Field, the world’s largest single gas field, located north east of Ras Laffan.

A team of four STATS isolation technicians deployed a remotely controlled Tecno Plug™ to provide double block and bleed isolation. The plug, which eliminates the need for tethers or specially modified pig-trap doors and is ideally suited for valve maintenance activities, was continuously monitored throughout client operations and remained stable for the full isolation period.

STATS also provided a test boundary for Dolphin to test the integrity of a flange joint using an In-Line Weld Test Tool. STATS technicians continued to isolate the line, allowing further client testing operations before finally unsetting and reverse pigging the plug back to the launcher.

Aberdeen-based STATS are a leading provider of pipeline and process isolation and intervention services and technologies across the oil, gas and petrochemical industries, which reduce system or plant downtime and enhance safety and environmental performance.

In addition to its core business in the North Sea, STATS is engaged in projects in Qatar, Malaysia, Abu Dhabi, Saudi Arabia and South America, while its Canadian subsidiary company recently won a major C$ 3 million (£1.85M) contract.

STATS Group managing director, Pete Duguid, said: “Our isolation services are increasingly in demand from major operators in the Middle East and Gulf States. This is the first time we have worked for Dolphin Energy but it is the second isolation project completed in Qatar in the last twelve months.

“We hope to extend our relationship with Dolphin and other operators in the region by continuing to provide innovation, value and rapid response to meet their isolation challenges.”

Mr Adel Ahmed Albuainain, general manager, Dolphin Energy, said: “Thanks to STATS Group and their professional approach, Dolphin was able to complete this element of its routine maintenance program, on time and without a lost time incident. Their commitment and dedication to this project was exemplary.”
