Bangkok Aviation Fuel Services Public Company Limited

BFPL, or Bangkok Fuel Pipeline Transportation and Logistics Co., Ltd., a company in the Bangchak Corporation group, and BPT, or BAFS Pipeline Transportation Co., Ltd., a subsidiary of Bangkok Aviation Fuel Services, have reported progress in their investigation into the case of oil contamination along Cheuapleung Road beneath the Rama III elevated bridge. On 16 September 2026, they opened up the ground for further inspection, as oil may have been seeping from the oil pipeline route in that area. Both companies have secured the area and are accelerating a detailed investigation to confirm the point of origin and the true cause. Once the cause is confirmed, they will expedite the preparation of a repair plan to submit to the Department of Energy Business and carry it out as quickly as possible, while managing oil transport through other channels so that deliveries can continue without interruption. Earlier, the inspection reported on 12 September 2026 found no abnormalities in the pipeline within the area examined, but because the source of the contamination still could not be identified, the inspection area was expanded to the surrounding vicinity, where slight traces of oil were found nearby. A connection to the incident cannot yet be concluded. After repairs, both companies will inspect conditions inside the pipeline system along its entire length of approximately 32 kilometres using Intelligent Pig equipment to ensure there are no other abnormalities. The oil pipeline system is an asset held under the operating licence of BPT, while BFPL has been granted the right to use and manage the pipeline system and has been the pipeline system operator since 1 January 2022. BPT and BFPL have arranged insurance policies covering both third-party liability and property damage and business interruption, and have also communicated with and provided assistance to members of the public, communities, and operators affected by this incident.

Ms. Thitipat Chotdechachainun, Secretary to the Minister of Energy, disclosed that officials detected a spot where oil was seeping from an oil transport pipeline in the Rama 3 area, after excavation revealed an underground cavity and oil mixed in the old drainage system. The pipeline system's operating licence is held by BAFS Pipeline Transportation Co., Ltd., or BPT, while Bangkok Fuel Pipeline Transportation and Logistics Co., Ltd., or BFPL, part of the Bangchak group of companies, is the pipeline system operator. Both companies must take responsibility for all damage incurred and must act in accordance with the orders of the Department of Energy Business. The Department of Energy Business has set out a three-part action plan: expediting the search for and repair of the damaged points, with the pipeline owner required to submit maintenance and repair history records for inspection; conducting a Pigging Test along the entire pipeline route of approximately 32 kilometres, under which any leakage or abnormality found requires operations to stop immediately; and preparing a plan to replace the pipeline and adjust the route in areas where defects or flaws are found, especially where the pipeline runs beneath bridge piers or high-risk structures, in order to prevent the problem from recurring in the future.

Bangkok Aviation Fuel Services Public Company Limited, or BAFS, said it immediately ordered a halt to oil deliveries through its pipeline for safety inspections after oil contamination was found in the drainage system along Chuea Phet Road and beneath the elevated section of Rama III Road at the boundary between Khlong Toei and Yan Nawa districts. BAFS Pipeline Transportation Company Limited, or BPT, which operates the oil transport pipeline system, said it is ready to cooperate with both government and private sector agencies to analyze the cause and expedite concrete solutions, with priority given to the safety of the community and the environment. It confirmed that oil transport management for Don Mueang and Suvarnabhumi airports and the northern region is still operating normally. If the investigation finds that any cause or damage falls within the company's scope of responsibility, the company is ready to accept responsibility for the damage under its insurance policy. BPT owns the oil transport pipeline system running from the Bangchak refinery to the Chong Nonsi oil depot and onward to the Don Mueang aviation fuel depot, the Suvarnabhumi aviation fuel depot, and the ground-level depot at the Bang Pa-in oil depot. The site of the incident is one section of that pipeline route. BPT has granted, for compensation, the rights to use and manage the assets of this oil pipeline system to Bangkok Fuel Pipeline Transportation and Logistics Company Limited, or BFPL, since January 1, 2022. BPT currently provides multi-products pipeline transport services covering only the northern part of the country, receiving oil from the Bang Pa-in oil depot for onward delivery to the Phichit oil depot and the Nakhon Lampang oil depot.

BAFS, or Bangkok Aviation Fuel Services Public Company Limited, has notified the Stock Exchange of Thailand that an oil leak was detected in the Fuel Road area beneath the Rama III elevated road on the evening of September 8, 2026, and that it immediately ordered a halt to oil transport through the pipeline system in that area, while accelerating an investigation to locate the leak point and contain the incident. The pipeline system belongs to BAFS Pipeline Transportation Company Limited, or BPT, a subsidiary of BAFS, and links oil transport from the Bangchak refinery and the Chong Nonsi oil depot to the Don Mueang and Suvarnabhumi aviation fuel depots and the Bang Pa-in oil depot. Currently, BPT and Bangkok Fuel Pipeline Transportation and Logistics Company Limited, or BFPL, which has held the right to use and manage the pipeline system since January 1, 2022, are urgently investigating and searching for the leak point. Initially, no severe impact has been found on the public, surrounding communities, or the environment. BAFS stated that pipeline oil transport operators can still manage oil transport as normal, so there has been no impact on aviation fuel transport to Don Mueang and Suvarnabhumi airports, or on ground oil transport to the northern region. Damage from the incident remains covered by insurance policies, and the company will monitor the situation closely and further notify the Stock Exchange of Thailand if there are developments that could have a material impact.
