Safety, Security, Health and Environment Policy (SSHE)

SSHE is fundamental for PTTEP's business. To achieve and sustain excellent performance toward relevant Sustainable Development Goals (SDGs), we put in place and adhere to an effective SSHE management system in order to ensure the safety and health of everyone involved in our operations and communities where we operate, environmental protection and the security of our people and assets.

To achieve our vision of being a zero incident organization, PTTEP shall:

  • Strive for a generative SSHE culture through accountable leadership and involvement of all employees and contractors.
  • Set measurable objectives, KPIs, targets, and action plans to deliver top-quartile SSHE performance, which is a line management accountability.
  • Fulfil compliance obligations with applicable SSHE laws, regulations, internal requirements, and national and international standards.
  • Manage SSHE risks to As Low As Reasonably Practicable (ALARP) throughout the PTTEP business lifecycle and when Management of Change (MOC) is applied.
  • Promote an effective health management system and enforce zero drugs and alcohol programs in the workplace.
  • Reduce environmental footprints in alignment with low carbon pathway, circularity concept, and positive Biodiversity and Ecosystem Services (BES) value creation.
  • Protect all employees and the organization from pandemics, natural disasters, security threats, and vulnerabilities by effectively managing emergencies, crises, and business continuity.
  • Empower everyone to exercise Stop Work Authority (SWA).
  • Commit to continuous SSHE performance improvement via regular training, stakeholder participation programs, and upgrading systems and tools with technology.

The successful implementation of this policy requires total commitment from PTTEP employees and contractors at all levels by being mindful in every action.

Safety, Security, Health and Environment Management System (SSHE MS)

PTTEP's SSHE Management System (SSHE MS) is an integration of the Company's safety, security, health, and environmental policies, vision, and corporate strategy, to mitigate risks induced by the Company's internal operations. The focus is on ensuring a safe work environment and prevention of work-related incidents, injuries and illnesses, as well as environmental impacts. The SSHE MS is also aligned with the International Association of Oil & Gas Producers (IOGP)'s guidelines as well as international standards like ISO 14001:2015 Environmental management System and ISO 45001:2018 Occupational Health and Safety Management System.

PTTEP's SSHE MS comprises of seven elements.

SSHE ElementAddressing
1. Leadership and Commitment Top-down commitment and SSHE culture, essential to the success of the SSHE MS
2. Policy and Strategic Objective Corporate intentions, principles of action and aspirations with respect to SSHE
3. Organization Resource and Documentation Organization of people, resources and documentation for sound SSHE performance
4. Evaluation and Risk Management Identification and evaluation of SSHE risks, for activities, products and services, and development of risk reduction measures
5. Planning and Operational Control Planning the conduct of work activities, including planning for changes and emergency response
6. Implementation and Monitoring Performance and monitoring of activities, and how corrective action is to be taken when necessary
7. Audit and Review Periodic assessments of SSHE MS performance, effectiveness and fundamental suitability

The Company has put in place the annual SSHE internal audit plan, to regularly monitor SSHE MS implementation. In 2022, 55 SSHE audits were carried out at the corporate level covering 100% of our exploration and production activities. External audits and certifications were also conducted in accordance with applicable international standards such as ISO 14001:2015 and ISO 45001:2018. Extent of such external audits cover our operations, including:

ISO 14001:2015 for Environmental Management System
  • Domestic Assets: Headquarters, Arthit, Bongkot (Greater Bongkot North – GBN and Greater Bongkot South - GBS), S1, PTTEP1, and Sinphuhorm
  • International Asset: Zawtika Project in Myanmar, Project in Malaysia (Located in Sabah and Sarawak)
  • Petroleum Development Support Bases: Songkhla and Ranong Bases
ISO 45001:2018 for Occupational Health and Safety Management
  • Domestic Assets: Headquarters, Arthit, Bongkot (Greater Bongkot North – GBN and Greater Bongkot South - GBS), S1, PTTEP1, and Sinphuhorm
  • Petroleum Development Support Bases: Songkhla and Ranong Bases

SSHE Culture Management

SSHE Culture development is a key in improving the SSHE performance of an organization. Since 2011, PTTEP has adopted a SSHE Culture improvement model based on the Safety Culture Maturity Model from IOGP (International Oil & Gas Producers Association) which identified five levels of SSHE Culture from Pathological, Reactive, Calculative, Proactive to Generative.

In the first survey on SSHE culture in 2011, PTTEP's SSHE Culture Maturity level was at 3.31 (Calculative level). Based on the survey results, the SSHE Culture Improvement Plan was developed and implemented for a survey every three years. Continuous improvement could be demonstrated from the results of the survey in 2017, in which the SSHE Culture Maturity Level for PTTEP reached 4.16 (Proactive level) from the highest at 5.

According to the 2020 SSHE culture survey result, the SSHE culture maturity level of the entire organization increased to 4.36 (Proactive level) without any distinctions between the result of top management and employees. Meaning that all PTTEP employees, regardless of position, have the same level of SSHE awareness. Furthermore, in 2020, contractors mode 1 were initially engaged and involved in the SSHE culture survey.

The Company sets a 3-year plan (2021-2023 SSHE Culture Improvement Plan) to further strengthen the SSHE Culture of the Company. Continuous monitoring will be periodically conducted to ensure improvement in SSHE Culture maturity level in all operating areas and achievement of the goal to become a zero incident organization (Target Zero). The next SSHE culture survey is scheduled in 2023.

Meanwhile, in 2022, PTTEP expanded the scope of SSHE culture improvement and development technique to cover contractors mode 2 performing the high-risk activities as elaborated in the Contractor Safety topic.

Embedding SSHE Culture

A culture of safety is firmly embedded in all PTTEP operations, which contributes to improving our safety performance toward achieving the goal of being a Target Zero organization. Although incidents still occurred, the Company remains fully committed to strengthening the safety culture, focusing on the safety of personnel and SSHE leadership. The emphasis is placed on personnel safety, SSHE leadership and the development of tools that support the PTTEP SSHE Leadership Program. The program was extended to cover frontline supervisors, who are the employees of PTTEP and contractors, in the previous year through training programs.

As a robust safety culture begins with competent workforces, the Company thus identifies training needs on SSHE for employees and contractors to provide them with basic knowledge and skills necessary for their assignments in accordance with Company's SSHE Training and Competency Standard. Table below shows example of highlight training programs conducted in 2022:

  • SSHE Leadership
  • Risk Assessment and Job Safety Analysis
  • Contractor Management
  • Basic Incident Investigation and Root Cause Analysis
  • Safe Lifting Operation
  • Process Safety Management
  • Corporate Emergency Management Team

Besides, the Company has continued to improve tools that promote safety culture, such as an electronic Safety Observation & Communication Card (SOC), Hazard Reporting Card (HRC), and Operational Control Verification Program. These tools primarily focus on workplace safety and increasing the observation and detection of unsafe behaviors and unsafe working conditions, with the aim of eliminating and/or reducing risks. PTTEP empowers all its employees and contractors to "Stop Work" when unsafe conditions or behavior is detected.

Emergency and Crisis Management

PTTEP recognizes that the petroleum exploration and production business requires high standards of safety. As such, PTTEP developed Emergency and Crisis Management Plans under the framework of the SSHE MS. The plans clearly outline a systematic structure to ensure the Company's readiness for emergency and crisis situations and their probable consequences to ensure the mitigation and recovery actions are put in place to reduce risk to the acceptable level, and giving priority to the protection of human lives, the environment, properties, and PTTEP's reputation. Joint exercises between the assets teams and corporate level personnel based on the Emergency and Crisis Management Plans are conducted on a regular basis. Results and feedback from these exercises are communicated to those responsible at the assets and corporate levels. They are used to improve the plans as well as to continuously enhance the competency of responsible personnel to effectively manage all forms of crisis situations.

Personal Safety

PTTEP believes incidents are preventable, to attain "Target Zero". This conviction is communicated repetitively from top management to all employees and contractors. Therefore, PTTEP emphasizes promoting safety culture in every stage of the work process. The Company's SSHE policy and management system were designed to meet relevant international standards, to manage work-related risks and ensure that everyone working with PTTEP returns home safely.

In 2022, the overall SSHE performance statistics in terms of the Lost Time Injury Frequency (LTIF) and the Loss of Primary Containment Rate (LOPCR) decreased compared to the previous year. Moreover, they were also better than the average performance of the industry peers reported to the International Association of Oil & Gas Producers (IOGP).

Following these incidents occurred in 2022, the Company strengthened our safety oversight of these assets by accelerating the closing of SSHE improvement gaps, communicating closely and enforcing strict measures to prevent the reoccurrence of such incidents. (Details on the number of personal incidents are shown in Health and Safety Performance Data.)

The results of incidents investigation showed that the main root causes were related to human factors, risk assessment and inadequate supervision onsite including inadequate communication of hazards and risks to workers. PTTEP put more focus on human factors and still maintains high safety standard and provides action plans by emphasizing on the safety leadership of the frontline supervisors to manage and communicate hazards and risks at site and promoting workforce's SSHE knowledge and competency. These are to ensure that employees and contractors will be able to work safely.

Transportation Safety

PTTEP has set safety targets for Motor Vehicle Incidents and Marine Vessel Incidents. Awareness on transportation incident prevention is promoted for all PTTEP transportation activities, including the Company's and contractors' vehicles and vessels, to ensure all workers will not face incidents and work safely. In 2022, there was one motor vehicle accident occurred. This accident, therefore, led to the revision of the Company's safety control measures at both internal and external training centers, even if it was identified as low risk. However, no vessel accident was reported for four consecutive years. (Details of the transportation-related accidents are shown in Health and Safety Performance Data.)

Contractor Safety

PTTEP has continuously improved SSHE Contractor Management to ensure that all suppliers and contractors can work and return home safely. The Company had established a long history of the annual SSHE Forum that brings together suppliers and contractors to demonstrate PTTEP's strong commitment to improving Safety, Security, Health and Environment and in achieving Target Zero.

However, due to the COVID-19 pandemic in 2022, PTTEP arranged a virtual meeting in order to follow the control of Ministry of Health instead. For subgroup meeting, they were organized with tailored content for each target group of contractors by the units directly dealing with contractors via virtual meeting as well. In addition, we continued to recognize and award contractors with good safety performance by maintaining our CEO's SSHE Performance Excellence Award recognition program.

PTTEP also worked closely with high-risk contractors. The Company conducted the SSHE culture survey of contractors to establish the work plan for improving and strengthening the SSHE culture to align with PTTEP.

PTTEP also provides guidance on health risk assessment to our contractors, to ensure that their occupational health risk assessment is on par with PTTEP's. The results are communicated to relevant parties and support the formulation of a risk mitigation plan to lower risks to an acceptable level. Such will improve our employees and contractors' health. The health risk factors which were considered include physical, biological, chemical, ergonomic, and psychological hazards.

Process Safetyclose | open

PTTEP’s mission involves the supply of oil and gas to meet the country’s energy demand. In the production process, oil and gas leaks can cause serious incidents that endanger lives, the environment and assets. Recognizing this potential, PTTEP integrates Process Safety Management into the SSHE Management System (SSHE MS) to prevent and mitigate Major Accident Events in our operations. The Process Safety Management system is based on the Energy Institute's guidelines which are in line with international manufacturing Process Safety Management requirements. It is based on the following four principles:

  • Commitment to prevention of Major Accident Events and Process Safety;
  • Understanding process hazards and risks;
  • Management of process hazards and risks to As Low As Reasonably Practicable (ALARP) throughout the asset development lifecycle
  • Learning and improving from experience.

These principles have been implemented by all relevant units across the organizations, to ensure the safety of all production and drilling equipment in all fronts, namely:

  • Design Integrity – to rigorously review MAE risks and build facility commensurate with the risk using recognized industry standards and best practices;
  • Maintenance Integrity – to maintain the built-in integrity throughout the asset's operating life;
  • Operating Integrity – to operate with discipline, within the defined integrity envelope; and
  • Well Integrity – to ensure Design, Maintenance and Operating integrity of our wells.

The integrity in the four fronts is identified as "barriers" to prevent and minimize hazards and their consequences. PTTEP regularly provides standard reporting and inspection and stresses that the responsibility for process safety lies in individuals according to the “My Barrier” program.  Changes on these barriers are managed through suitable Management of Change (MOC) processes to ensure additional risks are properly managed. Furthermore, PTTEP reported and analyzed leakage-related incident statistics from the production process in order to identify the causes and plan preventive measures. In 2022, PTTEP focused on improving the following processes:

  • Improve construction QA/QC including material quality assurance, qualification of contractors performing critical process e.g. welding.
  • Ensure construction material compatibility with producing fluid and contaminants characteristic.
  • Setup Technical Committee Meeting for each operating asset to monitor Process Safety performance and progress of asset specific LOPC (Loss of Primary Containment) reduction plan.
  • Roll out nine Process Safety Rules (Respect hazards, Apply procedures, Sustain barriers, Stay within safety operating window, Maintain safe isolation, Walk the line, Recognize change, Stop if unexpected occurs, Watch for weak signals) which are adopted from IOGP’s Process Safety Fundamentals.
Securityclose | open

PTTEP has performed Security Risk and Threat Analysis and Assessment in our operation control, which identify risks and assist in a prevention system and appropriate risk mitigation. In addition, we monitor security-related situations for all our operating sites around the world in order to promptly apply corresponding security measures to manage such risk to our personnel, stakeholders and our assets.

Occupational Healthclose | open

To be an organization whose employees possess healthy mind and body, the PTTEP medical and occupational health team has developed an E-Health Book system. It is an electronic health database that allows employees to easily access individual health records via the Company's Intranet. The E-Health Book contains employees' annual medical checkups and health risks which helps the Company plan health promotion activities and medical checkup programs that are appropriate for each employee and the whole company. Furthermore, the team conducted Health Risk Assessments (HRAs), the results of which are used to further improve current medical checkup programs appropriate to the employee's designated work in order to prevent health problems that may arise in the future.

The primary role of PTTEP's medical and occupational health team is to provide medical and occupational health advice to all employees and contractors. The team is also responsible for developing and maintaining occupational health standards, procedures, and approaches that promote a healthy and hygienic workplace, such as the Wellness Test, Ergonomic Consultation Campaign, and an annual medical and occupational health knowledge session for employees and contractors. (Course details and the number of participants are shown Health and Safety Performance Data.)

The COVID-19 pandemic affected not only the economy, but society, lifestyle and daily habits of all employees and contractors. As such, PTTEP has developed a plan to address the crisis in terms of operators' safety and occupational health, to ensure continuity of its business activities. PTTEP gives the utmost importance to occupational health and safety to workers and related persons. The following monitoring and preventive measures have been implemented to prevent the spread of the virus, in line with public health measures:

  • Head Office in Bangkok allows employees to alternately work from home and at office in order to reduce contacts and proximity during workplace activities.
  • In all operating areas onshore and offshore, safety measures are strictly enforced, such as vaccination for employees, their families, and contractors, isolation of workers travelling to the site, provision of information regarding health (health declaration), COVID-19 laboratory screening prior to entry to work areas, daily body temperature scanning and strict personal and workplace hygiene measures.
