A brig is a United States military prison aboard a United States Navy or Coast Guard vessel, or at an American naval or Marine Corps base. The term derives from the Navy's historical use of twin-mast sailing shipsâor brigsâas prison ships.
The network of crude oil pipelines in the U.S. is extensive. There are approximately 55,000 miles of crude oil trunk lines (usually 8 - 24 inches in diameter) in the U.S. that connect regional markets. The U.S. also has an estimated 30,000 to 40,000 miles of small gathering lines (usually 2 to 6 inches in diameter) located primarily in Texas, Oklahoma, Louisiana, and Wyoming with small systems in a number of other oil producing states.
The pipeline would run 875 miles from the Canadian border to Steele City, Neb., where it would join already-built sections of pipeline that carry oil to the Texas Gulf Coast. Keystone XL would carry 830,000 barrels of crude oil each day through its 36-inch pipeline that would run along a 110-foot-wide ribbon of land. Building a project this size will take 400,000 tons of steel and provide work for 7000, laboring over a period of about two years.
