An Innovative Permit to Work System Disconformities Identification (PTWDI) in the Commissioning and Start Up Phases of South Pars Gas Complex, Iran

The Permit to Work System (PTWS) provides a practical framework for the commitment of no harm to people or the environment to be respected by staffs and contractors. Furthermore, PTWS try to provide an effective means for identification of significant hazards and management of HSE risk activities that could result in serious or fatal injuries. The significance of PTWS role is more prominent in industries such as gas and oil refineries. Since a small failure or fault in these industries may lead to a catastrophic human and environmental disasters or enormous economic losses. South Pars Gas Complex (SPGC), Bushehr Province, Southern of Iran, is one of those industries which PTWS is an important part of operational risk and safety management. In this study in 2016, SPGC’s PTWS disconformities are investigated, and an innovative checklist for system disconformity identification is proposed for auditing PTWS procedure. Surveys and interviews with 14 experts by using structured Delphi method in two rounds indicated that questions raised in the checklist are system identification. Finally, audit quarries suggested in the checklist are divided into 10 main categories. First: SIMOPS Immediate, data sharing, 2-High risk activity, 3-Confined space entry activities, 4- HNF activities immediate data sharing, 5-Protecting PTWS counterfeit, 6-Immediate risk assessment, 7-Capability of permits tracing, 8-Capability of MOC and any flexibility, 9-Cost saving capability, 10-Immediate MSDS. This study was promoted PTW systems to ensure that authorized and competent people have thought about foreseeable HSE risks and that these risks are eliminated or minimized by using suitable control measures.
