Intelligent pigging of on-shore and off-shore pipelines in the U.K. has been carried out for a number of years. Case histories are discussed and some of the problems faced by pipeline operators in implementing a programme of intel Iigent pigging are examined. The Regulators’ roles in this activity arise from powers conferred by the Pipe-lines Act 1962
(applicable to on-shore pipelines), and the Petroleum and Submarine Pipe-lines Act 1975 (applicable to off-shore offshore pipelines). Much of this legislation will be replaced by new Pipeline Safety Regulations in 1996. This new Iegislation and the reasons for change are described in the paper.
