Operational risk management review for two national oil refineries

Extensive operational and design review of key refinery assets to support regulatory and internal assurance requirements


For two national oil refineries we provided a comprehensive review of many key process units. The client, driven by both regulatory and internal pressures on safety assurance, wished to ensure that continued operation of the two sites was safe. Although the projects were driven by tight time schedules there was also significant pressure for a review that would provide wide-ranging recommendations on bringing the two plants in line with modern refinery design standards.


The reviews were based on a HAZOP approach using standard guidewords/methodology, consistent with US OSHA requirements and UK Chemical Industries Association (CIA) guidance. For this client we developed & maintained clear, customized, in-house templates for HAZOP/SIL recording and action tracking, readily tailored to individual client and project needs. We have also worked successfully using commercial HAZOP recording software, depending on specific client/project requirements. We retain a pool of mature expert HAZOP and SIL chairmen, who consistently receive excellent client feedback for their judgement, diplomacy, integrity and balance in completing HAZOP and SIL studies. We have also formed strong relationships with specific world-class operating companies and design contractors, who recognise Arthur D. Littleā€™s inherent strengths and the value we bring to their most prestigious projects


We provide premium Hazard Identification services, strongly focused on the principles of owner/client/licensor team engagement, true lateral thinking, conflict avoidance and generation of high added-value practical recommendations for project enhancement. With this client we have maintained a relationship for more than 15 years, providing review of new assets, unit revamp and debottlenecking, major modifications and now major assurance review to meet regulatory and shareholder requirements
