Trans-Alaska Pipeline System a specific gravity of 29.9 API at . In 2008, the pipeline carried approximately , less than its theoretical maximum capacity of or its actual maximum of in 1988. From Pump Station 1 it takes an average of 11.9 days for oil to travel the entire length of the pipeline to Valdez, a speed of . The minimum flow through the pipeline is not as clearly defined as its maximum. Operating at lower flows will extend the life of the pipeline as well as increasing profit for its owners. The 2012 flow of 600,000 bbd is significantly less than what
CLH Pipeline System CLH Pipeline System The CLH Pipeline System (CLH-PS), formerly the Government Pipelines and Storage System (GPSS), is a United Kingdom pipeline system run by Compañía Logística de Hidrocarburos (CLH). The network at one time consisted of over of pipeline and 46 other facilities. However, several of these facilities were closed before the GPSS was sold in 2015 and a number of the pipelines were mothballed and later 'abandoned'. Earlier the total number of facilities on the GPSS was much larger than 46. For example, in 1989 there were 40 Petroleum Storage Depots in operation plus large numbers of other facilities
