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.
