Abstract:
1. A liquid transport system, comprising: (a) a pipeline defining a closed loop fluid transfer path wherein a transfer fluid can be caused to flow, from a starting location, to a destination location; (b) at least first and second transfer fluid source/destination nodes disposed along the fluid transfer path, a separate joining conduit joining each said transfer fluid source/destination node to a liquid source/destination; (c) first and second pig launchers operatively connected to said fluid transfer path such that said first and second pig launchers are always in the fluid transfer path; (d) at least one pig operative with said pig launchers and wherein said at least one pig can be moved along the fluid transfer path between said first and second pig launchers thereby to remove such transfer fluid from such fluid transfer path; and (e) one of said source/destination nodes being connectable to both a source/destination and to a non-product liquid supply, through a hook-up panel.
