The pre-commissioning work on the two pipelines included flooding, cleaning, gauging, high pressure flushing and hydrotesting the pipelines from onshore to enable them to transport gas and condensate from the field to Shell's onshore gas plant at St. Fergus. "The vision of the Goldeneye venture is to deliver safely an outstanding, economic, environmental and societal performance," said David Stephen, project engineer, Pipeline and Process Services. "In line with this vision and Halliburton's overall philosophy, the need to work safely and eliminate any potential harm to the environment was imperative. The pre-commissioning worksite was located within marshlands designated as a Site of Importance to Natural Science, presenting a challenge to the work team to ensure that the site remained a hydrocarbon and chemical spill-free zone."
Halliburton's PPS team in Aberdeen met the challenge. Through execution of a project that included the mobilization and installation of a 2,400-horsepower pumping spread, 9,500 work hours and 48 days on site, the PPS team achieved zero environmental and safety incidents.
The Goldeneye Field is operated by Shell UK and lies in the Outer Moray Firth area of the UK Central North Sea, 100 kilometers northeast of the St. Fergus gas terminals. Saipem UK installed the 20-inch by 101 kilometers gas export and four-inch Mono Ethylene Glycol pipelines simultaneously in water depths of 120 meters using their pipelay vessel, Castoro Sei.
