VALDEZ (AP) -- An instrument used to check the condition of the 800-mile Trans-Alaska pipeline arrived at its destination damaged, Alyeska officials said Monday.
The data-collecting instrument, called a ''pig'', was launched from pump station 4 on June 26th. It arrived at the end of the pipeline in Valdez with a ring of metal wrapped around it. The metal is a check valve seat ring.
While there is no indication of external damage to the pipeline, a team has been mobilized to inspect each of the 38 valves between the pump station 4 and Valdez, said Bill Howitt, a senior vice president at Alyeska.
