Analysis of Petronas Carigali Sdn. Berhad Sarawak Operation (PCSB SKO) injurious accidents

Petronas CarigaIi Sdn Bhd Sarawak Operation and its contractors 1999 lost time injury frequency CLTIF) at 0.83 was considered better than the International Association of Oil and Gas Producer 1999 lost time injury frequency of 1.94. However the figure was higher if compared to other Malaysian oil and gas operators namely Sarawak Shell Berhad/Sabah Shell Petroleum Company and ESSO Production Malaysia Incorporated whose 1999 lost time injury frequencies were at 0.5 and 0.71 respectively. Petronas CarigaIi Sdn Bhd Sarawak Operation safety performance was affected by poor contractors safety performance. The objectives of the analysis were to gauge effectiveness of the company and contractors Health, Safety and Environmental Management Systems CHSEMS), identify factors attributed to the injurious accidents and provide recommendations for improving the company overall HSE performance. The method involved quantitative analysis of historical data of Petronas Carigali Sdn Bhd and it's contractors' injurious accidents from 1996 to 1999. Frank E. Bird's incident ratio model was used as a comparison to gauge the effectiveness of the Health, Safety and Management Systems of company and contractors. The finding of the analysis show that Petronas Carigali Sdn Bhd Sarawak Operation incident ratio was a reflection of the model Frank E. Bird's incident ratio and could be concluded that the company's Health, Safety and Environmental Management System (HSEMS) was effective (An audit carried out in 1999 show that the company was 74% compliance to its HSEMS). However contractors' incident ratio model was distorted with total recordable injury frequency of contractors higher than that of the company. Thus it can be deduced that the contractors HSEMS were ineffective. The analysis highlighted that injurious accidents tend to happen at the initial period of work and after breaks. This demonstrated the importance of toolbox and pre-job meeting stressing hazards of the job and conditioning personnel to the allocated tasks. The numbers of injurious accidents tend to be high on weekends and peaked on Wednesday, indicating that personnel were off guard during the traditional rest period of Saturdays and Sundays. The increased in accidents on Wednesdays may be attributed to crew change schedule. However this cannot be confirmed due to lack of data on the crew change loading. The analysis disapproved the assumption that increase in activities resulted in increased number of accidents. Contractors' personnel were more prone to injurious accidents than company personnel. Personnel subjected to injuries were mainly technicians and riggers' who were involved with lifting operations. The most common body parts injured were the hands, thumbs and fingers that totaled to 66% of overall injuries. The recommendations made were for a compliance audit on company HSEMS. And an urgent training program on rigging and slinging for company and contractors' personnel. Lost time injuries incurred were mainly on rigging and slinging operations. It also stressed the importance of pre-job meeting and job hazard analyses which need to be carried out. Further study is required on contractors' compliance to Occupational Safety and Health Act (OSHA), on the availability of Safety Policy and the presence of an organization and requirements to implement the Safety Policy. Riggers' Personnel who are involved with the physical manual work such as moving of equipment making use rig, winches and other lifting devices and the physical work in breaking of flanges and other manual operations, considered as a semi-skilled worker. Wireline Crew2 Skilled personnel specially trained to work on well downhole subsurface equipment, and making use of steel slick line with tool attached at end of line operated by a hydraulic power pack.
