GE will help Chevron Corp. tap a large subsea oil and gas field located some 65 miles off the coast of Africa near the Congo River estuary. GE will build nine subsea control modules, seven subsea “trees”, and other technology valued at $165 million for the $2 billion project called Lianzi Field. The control modules are the nerve centers for subsea pumps, wellheads and other machinery. The multi-ton “trees” are an assembly of underwater valves and other equipment that control oil and gas flow. They machines work on the seabed and must withstand crushing deep sea pressures.
Taking the Plunge: GE machines like these subsea trees and manifolds will help Chevron pump oil from wells located 65 miles off the coast of Africa and 3,000 feet under the sea surface.
The GE machinery will connect to a 27-mile long electrically heated “flow-line” laid by a reel-ship 3,000 feet beneath the sea, the deepest such pipeline in the world. The pipeline will deliver 46,000 barrels of oil equivalent per day from the field to an existing Chevron oil platform located off the coast between Angola and the Republic of Congo.
“West Africa is one of the world’s key hydrocarbon basins, and we are excited to be working with Chevron Overseas Congo Limited as operator of the Lianzi project, the first cross-border development in the region,” said Dan Heintzelman, CEO of GE Oil & Gas. “This contract win is not just an expansion of our relationship with Chevron. It represents our product competitiveness in the global marketplace, ongoing commitment to the region and continued demand for our state-of-the-art technology solutions.”
GE plans to complete the first subsea tree for Lianzi within a year. Chevron expects to start pumping oil from the field in 2015.
GE has supplied its energy customers with more than 900 subsea tree systems. They have been installed at every major oil and gas field around the world. GE and Chevron, for example, are working on another huge subsea oil and gas field off the coast of northwest Australia, the Gorgon Project, which holds an estimated 40 trillion cubic feet of gas. Chevron has ordered $1.8 billion in GE machinery and services, including five massive mobile power plants that will supply the Gorgon project with 650 megawatts of electricity. Chevron will use the electricity to compress and cool natural gas into liquid that can be shipped to customers around the world.
