Spill Management

Importance and Mission

Exploration and production activities within the oil and gas industry inherently carry the risk of accidental spills during product transportation, whether via pipelines, marine vessels, or road and rail tankers. These spills can pose a significant threat to the environment, surrounding communities, and cultural heritage. Mitigating this risk is paramount. PTTEP prioritizes the development of robust operational controls and effective mitigation measures to prevent spills. Furthermore, maintaining a high level of preparedness for spill response and management is crucial in minimizing environmental impact should an incident occur.

Goals

Zero spill

Management Approach

As part of Safety, Security, Health and Environment (SSHE) commitment, zero spill is one of SSHE Target Zero in Company’s annual SSHE KPIs. To achieve the target, PTTEP focuses on effective incident prevention and management where potential spill scenarios are assessed for responses preparation. The Spill Management Plan and the Spill Response Plan are crucial in defining the company’s organizational structure and response procedures, encompassing documentation, equipment, and resources required for effective spill management.

The company’s spill management plan follows the 3-Tier Spill response system defined by the IPIECA and the International Association of Oil and Gas Producers (IOGP). The response system is as follows:

Tier 1

Spills that require response from Asset capability and resources.

Tier 2

Spills that require response from local and national resources, such as Subdistrict/Department of Local Administration Organization, Department of Disaster Prevention and Mitigation, Marine Department, Royal Thai Navy, Oil Industry Environmental Safety Group Association (IESG) for Thailand, and the Petroleum Industry of Malaysia Mutual Aid Group (PIMMAG) for Malaysia.

Tier 3

Spills that require response international response resources, such as Oil Spill Response Limited (OSRL), in collaboration with Tier 2 resources.

Spill Risk Management

PTTEP manages spill risks in accordance with legal requirements, regulations, and the company's risk management process for all exploration and production (E&P) activities. The objective is to assess and mitigate spill risks to a level deemed "As Low As Reasonably Practicable" (ALARP). To ensure effective response and mitigation, Spill Impact Mitigation Assessment (SIMA) are conducted to determine appropriate spill response measures for different scenarios. These risks undergo regular audits and reviews to ensure proper management and mitigation.

The company regularly conducts emergency drills at the corporate and asset level to assess the readiness and capacity to manage the spill and propose plans for continuous improvement. The company, as a member of IESG, has supported the preparation of the spill management system in Thailand, such as joining committees at various levels, supporting the provision of oil spill equipment, participating in equipment readiness audits and annual emergency drills, and other related businesses.
