Supply Chain Management
PTT focuses on effective supply chain management in order to prevent and reduce supplier environment, society, and governance risks that may impact stakeholder’s trust in PTT’s operation. Supply chain management can be classified into 2 levels: corporate and business. The corporate level is responsible for general products and services procurement; in
addition, corporate level is responsible for supply chain governance and PTT Group’s value added initiatives. At the business unit level, products are procured according to the business unit’s needs, these include: hydrocarbon or raw materials, which are high value transaction and include feed stock for refining process; and crude oil and other petroleum-based products, which are procured on the international market. The PTT Group Supply Chain Environmental Social and Governance Management Program was created to increase PTT Group’s supply chain effectiveness.

PTT Supplier Sustainable Code of Conduct (SSCoC)

The PTT Supplier Sustainable Code of Conduct covers relevant regulations and requirements, Code of Business Ethics, social responsibility, occupational health and safety, and environment management. The document is available in Thai and English and is required to be enforced by suppliers whose contract value is greater than 2 million baht. The Code of Conduct is also enforced with suppliers whose work may pose environmental and safety impacts, as well as those who expressed interest in being in PTT’s Vendor List. In addition, PTT has identified a strategy to support and manage suppliers and communicate guidance and knowledge of policy on sustainable procurement in alignment with the PTT Supplier Code of Conduct via different channels, such as the Supplier Relationship Management (SRM) Seminar and

Supplier Risk Assessment

PTT’s management structure for suppliers and contractors allows for the stringent supervision of supplier risks in order to prevent impacts to PTT’s business. PTT evaluates the risks of its main groups of suppliers by considering factors in 2 dimensions: ESG Supplier Risk and Buyer Risk, where PTT is the buyer, covering areas as high spending/high volume
purchasing, critical component suppliers, or non-substitutable products or services.
The level of supplier risk is considered a determining factor in evaluating the level of supplier criticality and establishing appropriate supplier management strategies. Suppliers can be classified into 4 levels, as follows:

Supplier Management

PTT sets supplier management measures in order to ensure the compliance of the supplier’s conduct with the required standards as well as the supplier’s ability to meet the increasing demands for products, achieve targets, maintain product quality, cultivate good relationships between suppliers and PTT, and build awareness of suppliers on PTT’s corporate sustainability position.

Corporate Level

PTT has standards for selecting, assessing and auditing suppliers in a fair and transparent manner in terms of the supplier’s ability to secure business operations and respond to PTT’s needs. PTT uses a pre-qualification questionnaire (PQ) to evaluate each supplier’s potential in various aspects including service readiness, production rate, transportation, safety, occupational health, environmental aspects, and industrial standards. Qualified suppliers will be included in the PTT Approved Vendor List (AVL). Suppliers must be able to operate according to the PTT Supplier Sustainable Code of Conduct. The management of AVL is under the supervision of the AVL Committee and the working committee. Supplier performance is further assured through additional specifications stipulated in the Terms of Reference (TOR) prepared for all procurement assignments.

In addition, to manage risks incurred from product delivery, PTT has stipulated certain conditions in the TOR to ensure that the supplier’s operations are conducted in compliance with relevant regulations and contracts, especially those involving safety, occupational health and environmental risk. The Risk Assessment for Contractor SSHE Management program has been developed to select potential contractors. Suppliers, whose assessment scores are lower than the required level, will be disqualified.

Business Unit Level

PTT’s supply chain management strategy for petroleum products, LPG, and biofuel procurement is focused on receiving the correct product quality and quantity that is on-time, safe, and environmentally-friendly, through a transparent and traceable process both from PTT and suppliers’ sides. In addition, PTT focuses on creating added value for petroleum
products, LPG and biofuel products in the PTT Group’s supply chain.

In addition, stipulations on environmental and social sustainability, volumes and delivery periods are included in all of PTT’s short-term and long-term contracts with refineries and biofuel suppliers. The requirements related to environmental and social practice and criteria for performance excellence are defined in each contract based on the Supplier Sustainable Code of Conduct. ESG factors are used to assess the minimum level of quality and quantity of both existing and new contracts according to the strategic supply chain management plans, consisting of quality, economic, environmental, safety, occupational health, and community aspects.



Supplier Assessment and Audit

PTT has in place supplier assessment and audit programs to manage risks, define mitigation plans, and evaluate performance based on jointly developed mitigation plans. Assessments take into consideration quality/quantity/safety in production and delivery, PTT’s basic requirements, and minimum requirements in labor and environmental laws and management standards such as ISO 9001, ISO 14001, and OHSAS 18001.
For refinery suppliers, PTT organizes a monthly meeting with critical suppliers through the Supply Coordination Committee, and conducts site visits to carry out customer satisfaction surveys in order to improve the delivery of petroleum products. To manage ESG risks, PTT and suppliers jointly identify the cause of issues, work out a resolution, as well as evaluate the results of the mitigation plan.
In addition, PTT conducts supplier audits for the refinery group and Ethanol/B100 factories, covering criteria such as quality of products and services, work process and delivery, environmental health and safety at work, adherence to the PTT Supplier Sustainable Code of Conduct, transportation of products and services, and social and environmental impact from work processes. Mitigation measures are developed for areas within the production plant, storage, and distribution point. Relevant PTT functions including procurement planning, operation, quality control, and QSHE, conduct on-site visits to the refineries and Ethanol/B100 factories as defined in the annual audit plan. Site audits will rotate in order to ensure a comprehensive reach of the audits, and the refineries and factories are required to improve their performance within the required timeline and update their improvements to PTT. Results of supplier audits will be presented to the PTT QSHE Steering Committee meeting.
For the International Trading Business Unit, PTT uses the register counterparties process to screen the list of suppliers and establish PTT’s Counterparty List. The suppliers must adhere to the PTT Group Ship Vetting Standard, which assesses suppliers’ ESG performance based on marine vessel safety standards. This enables PTT to manage the risks of oil spills that could cause major impacts on the marine environment and business operations. PTT has also joined Oil Spill Response Limited (OSRL) to receive support in the case of an oil spill at sea incident, and to reduce the subsequent impacts on the environment and local communities.


SSHE Management System for Supplier and Contractors

PTT developed the SSHE Management System (SSHE MS) for suppliers and contractors as guidance for controlling and managing operations. The system includes the following elements:
           •  The integration of SSHE screening criteria into procurement procedures;
The identification and assessment of SSHE-related risks that may arise from contractors, and the specification of SSHE responsibilities, 
               approaches for control and operations, and the reporting of the contractors’ SSHE performance as required;
Development of initiative to improve contractors’ SSHE performance during turnarounds, provide SSHE training to contractors whose 
               tasks involve specific risks, and establish SSHE suggestion system for contractors;
Communication of SSHE expectations to contractors through various channels in order to cultivate awareness, improve the 
              performance of contractors as well as to build contractor capabilities to respond to PTT needs; and
           •  Provision of support to contractors to improve SSHE performance to meet the standards expected by PTT.

In addition, PTT established specific approaches to manage supplier and contractor risks, including:

      Target setting for controlling accidents from vehicles and transport to reduce the major transport accidents to zero by 2020, and establishment of the PTT Group Road Safety Management Guidelines. The guideline specifies approaches including random checks on logistics trucks; use of IVMS (In-Vehicle Monitoring System) technology, which is connected to closed-circuit cameras and GPS systems to monitor driver behavior and collect statistics to analyze causes of accidents involving logistics trucks; investigation of all major accident cases involving vehicles and logistics truck to determine root causes and to prevent such accidents from re-occurring; and communication and organization of training on PTT Group’s Road Safety Management Guidelines in order to inform and encourage safe practices by relevant parties, such as Defensive Driving courses.
      Development of PTT Contractors Safety Management Manual as an approach to control and manage the safety of contractors working in PTT’s operational areas.


Cooperation in the Supply Chain

PTT aims to improve procurement processes through the PTT Group Integrated Supply Chain Management and Optimization (GISMO) project with refineries in PTT Group, including Thai Oil Plc., PTT Global Chemical Plc., and IRPC Plc. to increase the competitiveness and synergy across the petroleum supply chain – reducing capital investments and creating added value for PTT Group. In addition, the project also leads to the development of environmentally-friendly processes and the reduction of carbon dioxide emissions of PTT and PTT Group companies.

GISMO consists of 5 sub-projects including:

   Petrochemicals and Refining Integrated Supply Chain Management (PRISM): Maximizing the value of the supply chain through cooperation between petrochemical and refinery companies in PT T Group, by exchanging information and inspiring developments in technology and innovation.
   Group Logistics Management (GLM): Managing logistics for group asset readiness to respond to future growth; building capacity through group-wide collaboration to reduce capital investments and create added value; reducing social and environmental impacts through group sustainability, and increasing group intelligence at the national and international level to respond to changing conditions – leading to best practices in logistics at the regional level. Presently, the project has been transformed into a permanent department, the PTT Group Logistics Management Department.
   Supply Chain Optimization (SCO): Supporting benefits for the oil supply chain through operational approaches that reduce capital investments and cooperation to enhance understanding of supply chain management. Presently, the project has also become a permanent department, the Supply Chain Management Department.


In addition, the Operational Excellence (OPEX) project aims to strengthen the synergy amongst PTT Group through sharing of best practices in management, covering 12 areas, including Reliability and Asset Integrity, Operations, and Value Chain Management. The OPEX project is deployed and applied to PTT Group companies to allow them to analyze and plan streamlined work processes across the entire company. For instance, the sharing of best practices from the Gas Separation Plant on business continuity to ensure that no unplanned interruptions to processes lead to losses in business opportunities, to other PTT Group companies.


Local Procurement

PTT supports local procurement and service (within Thailand) and encourages the procurement of goods from operational areas in order to provide economic, employment, and income generation support for the locals with the advantage of lower costs and faster transportation.  As a result of PTT’s commitment to building long-term relationships with the communities where it operates, the organization gains each community’s license to operate. Moreover, PTT also encourages suppliers to operate with care and responsibility toward society and local communities and to support procurement within the local area in order to lower the cost of goods and support the local community.
