Bangchak Corporation Public Company LimitedBCP's BFPL halted oil transport and cooperated with Bangkok authorities after residents' oil-smell complaints; no leak found, so impact on BCP is unclear.

Chadchart Sittipunt, Governor of Bangkok, visited the area around Chuea Phet Road in Khlong Toei district on 13 September 2026 to follow up on residents' complaints of a strong oil smell wafting from a drainage pipe beneath the U-turn point at Rama III Bridge, after excavation work was accelerated from 11 September to search for leaks and contamination points. Chadchart said the oil company and experts had thoroughly inspected the oil pipeline, including opening the pipe along its length, measuring its thickness and conducting pressure tests, but no leak had been found, so the source of the oil still cannot be clearly identified. The pipeline is currently not transporting oil and there is no pressure in the system. In the latest situation, the amount of oil and the smell have clearly decreased, with only an oil film found on the water surface. The initial hypothesis is that it may be old oil that had accumulated in the soil cavity outside for a long time before seeping into Bangkok's drainage system through joints between pipes. Bangchak Corporation Public Company Limited, or BCP, said that Bangkok Fuel Pipeline Transportation and Logistics Company Limited, or BFPL, a company in the BCP group which holds the right to use and manage the oil pipeline of BAFS Pipeline Transportation Company Limited, or BPT, sent officials to the area immediately on 7 September and has worked with Bangkok Metropolitan Administration around the clock. It also ordered a halt to oil transport through the pipeline system from the morning of 8 September for safety and to allow a detailed inspection of the pipeline route. The latest inspection results confirm that no leak was found in the inspection of the oil pipeline in that area.
