## MINISTER OF STATE IN THE MINISTRY OF PETROLEUM & NATURALGAS (SHRI SURESH GOPI)

(a) A total of five accidents have occurred due to leakage or rupture caused by corrosion during the last 5 years and so far in the current year.

Oil Industry Safety Directorate (OISD) has notified the standards related to pipeline safety  namely  OISD-STD-141  (for  liquid  pipelines),  OISD-STD-214  (for  LPG  pipelines), and OISD-STD-226 (for natural gas pipelines) to enhance the pipeline integrity.

Advanced  diagnostic  tools  such  as  intelligent  pigging  and  Magnetic  Tomography Method (MTM) are used to detect internal defects or corrosion in pipelines as per relevant standards.  Corrosion  protection  and  mitigation  measures  like  external  coating  systems, dosing  of  corrosion  inhibitors  and  injection  of  biocides  are  implemented  in  pipelines whenever needed.

Furthermore, oil and gas companies have implemented various measures to protect underground pipelines from leakage and rupture which inter-alia, include use of Supervisory Control and Data Acquisition (SCADA) systems for real-time monitoring, regular security patrolling,  Leak  Detection  Systems  (LDS),  Pipeline  Intrusion  Detection  Systems  (PIDS), negative pressure wave leak detection system, Geographic Information System (GIS)-based pipeline mapping, etc.

(b)        Public  Sector  Oil  Marketing  Companies  (OMCs)  have  conducted  various  training sessions, including defensive driving and simulator-based training, covering more than 3.5 lakh crew members over the past five years.

(c)   Oil Industry Safety Directorate (OISD) has conducted 1,316 external safety audits of oil and  gas  installations,  covering  over  51,600  km  of  cross-country  pipelines  during  the  past five years.

(d)    The oil PSUs have undertaken various initiatives to raise public awareness about the opportunities  and  safety  measures  in  petroleum  transportation  and  storage,  particularly  in rural areas, including those in Gujarat. These initiatives include:

- i. Village awareness programs around oil & gas installations to highlight the potential dangers, associated risks, and necessary safety measures.
- ii. Awareness  campaigns  on  emergency  scenarios, environmental protection, and general safety practices.
- iii. Displaying hazardous chemical (HAZCHEM) signs on tank trucks.
- iv. Vehicle tracking is implemented
- v. Defensive driving and simulator-based training to Tank Truck (TT) crew.
- vi. Safety measures like limiting device, Terminal Automation System (TAS), advanced fire fighting systems and Remote Operated Shut-off Valves (ROSOV)
- vii. Promoting safety measures at Retail Outlets including awareness campaigns through billboards.
- viii. Promoting  safe  handling  of  LPG  cylinders  through  various  mediums  such  as  TV/ Radio jingles, short clips, LPG Panchayat, awareness campaigns etc.

Offsite  mock  drills  are  also  conducted  by  the  District  Administration,  with  active participation from Oil and Gas Companies, to ensure preparedness for emergency situations and to enhance coordination during crises.
