Explorer to Shut Pipe Temporarily New Year's Eve NEW YORK (Reuters) - Explorer Pipeline Co. said Monday it plans to idle its entire oil products pipeline system, which feeds the Midwest, for 20 hours starting New Year's Eve to guard against any unexpected Y2K incidents. ``We will do the same thing as Colonial. We will shut our system temporarily,'' Explorer President and Chief Executive Officer Scott Van Dyke told Reuters by telephone. The Houston-to-Chicago Explorer Pipeline, the second largest refined products pipeline in America and jointly owned by eight oil companies, can pump as much as 700,000 barrels per day of refined products like gasoline and distillates. Colonial, the No.1 pipeline firm, has already announced an eight hour shutdown of its entire 5,300-mile-long oil products line from Houston to New York, starting before midnight December 31, to avoid any such disruptions. Officials at Tulsa, Oklahoma-based Explorer said the Explorer line shutdown will last from 5:00 p.m. (CST) December 31 until 1 p.m. January 1, 2000. For Colonial, which has a capacity of some 2.1 million bpd, the shutdown is due to start at 6:30 p.m. (EST) and last for eight hours. Experts fear potential problems to communications or power supply, for instance, due to the so-called Year 2000 computer bug, which may cause some older computers to malfunction after the date roll on December 31, 1999. ``We have excess capacity this time of year so the shutdown will not be a big problem...We should be able to compensate for the supply loss,'' Tom Jensen, Explorer's manager of shipper relations and transportation services, told Reuters. He said although the Explorer system was Y2K-compliant, like Colonial's, the company was taking no chances. ``If we had any problems with communications or power supply we want to make sure that our line is down at that time so we have no unforeseen problems,'' Jensen told Reuters.
