BRES Successfully Uses Remote Operated Pipeline Isolation Systems for the First Time in the World
Bombay, India - Asian Marine Contractors (AMC), a subsidiary of Brown & Root Energy Services, recently completed the replacement of two risers and subsea isolation valves on the NF Platform Bombay High, India, with the use of remotely operated pipeline isolation systems. This is the first time in the world that such state-of-the-art technology has been used subsea for online replacement at such high pressure. Brown & Root Energy Services is a business unit of Halliburton Company (NYSE: HAL).
The turnkey contract, awarded by Oil and National Gas Corporation (ONGC) of India to AMC, recognized the need to reduce production loss from Bombay High during the riser change out and subsea valve installations which were installed using hyperbaric welding techniques from the DSV Rockwater 1. Rockwater 1 is owned and operated by Brown & Root Energy Services.
AMC in turn awarded a contract for the design, manufacture and operation of remote operated isolation plugs to Plugging Specialists International (PSI) of Norway. This remotely operated computer controlled isolation plug has two modules, each module having one set of grip and seal units to cater for complete redundancy. The isolation plug system pigging modules also encapsulated all the valves hydraulic pumps/motors, microprocessor controllers and battery.
The activation of gripping and sealing was done through remote sensing Extra Low Frequency (ELF) signals, activated from outside the pipe. This technology allowed the isolation system to be located a considerable distance from the platform and allowed the negotiation of a significant number of bends and pipeline fittings.
"Brown & Root Energy Services is proud of our team's technological leadership and world class performance on this NF Risers project," said Larry Farmer, president, Brown and Root Energy Services. "Together with our subcontractors, we have demonstrated our expertise in providing and executing technology-driven solutions to meet our customer's challenges."
Undertaken in October, the work included the installation of two subsea isolation valve skids each with actuated ball valves and check valves, pipeline tie-in spools, replacement risers, control umbilicals and replacement topsides pipe spools. The pipeline tie-ins were completed in record time with the NF platform being shut-in for 13 days for the gas pipeline shutdown and 14 days for the oils shutdown against a scheduled shutdown of 25 days for each.
