Restoring Integrity to Aged Petroleum-Production Facilities

摘要

BP and its local predecessor Amoco have produced oil and gasoff the east coast of Trinidad for over 30 years. Thisproduction originates from eight offshore fields and istransported to onshore terminals through an extensive pipelinenetwork. Gas is further shipped for domestic use or LNGproduction. Oil is temporarily stored onshore and then tankerloaded for export. Despite excellent business success for theoperator and nation, maturing production, long service timeand constrained resources have taken a toll on the technicalintegrity of facilities.In late 2000, a major program to restore integrity wasdeveloped, resourced and implementation begun. Therestoration strategy was based on a four-step process involvingassess, restore, upgrade and sustain. The program addressesthe technical integrity of all assets including offshore topsides,subsea structures/pipelines, onshore terminals, tankage andoil/gas exports systems. It also includes enhancements toprocess safety protective systems and development of acomprehensive major accident hazards management system.This paper outlines the many problems, solutions,challenges and successes of the integrity restoration program.It describes the required organizational commitment to amulti-year improvement campaign and a shared vision ofsustained, world-class integrity management. Lessons learnedfrom the program are now being applied to BP Indonesiaoperations offshore Java and elsewhere; specific areas ofcorporate sharing are described.
