Measuring Process Safety Implementation through Assessments and Audits

摘要

PETRONAS, the national oil company of Malaysia was formed in 1974. Since then, it has transformed into a fully integrated multi-national Oil and Gas company which is operating in more than 30 countries. A structured HSE Management System (HSEMS) had been established and implemented across the Group in 1999. In 2006, PETRONAS has enhanced its HSEMS through integration of process Safety Management (PSM) requirements with greater focus given on process Hazards Analysis, Management of Change, process Safety Information, Operating Procedures, Pre- Activity Safety Review, Mechanical Integrity, Design Integrity and Proprietary & Licensed Technology Assessment. The implementation progress on above are measured and regularly reported to the Management. Although systems and procedures on the PSM elements have been established and implemented as reported in the PSM audits and self-assessments, there are still concerns on the effectiveness e.g. the audits scoring are not consistent with findings from HSEMS assurances and related assessments such as the Integrated Plant Operations Capability System (iPocS) assessment. Efforts have been put in place to improve and standardize the assessment criteria used in the various assessments. This will ensure that process safety requirements are adequately addressed and the assessment rating and progress reporting reflect the actual implementation at sites. To further enhance the HSEMS and ensure effectiveness, key expectations, roles and responsibilities with regards to the specific process safety elements are prescribed in the form of Mandatory Control Framework (MCF) for implementation by the operating units. Compliance to the MCF, which was introduced in 2011, are monitored and also subjected to regular audits.
