Bangkok: A significant leak has been discovered in the Rama 3 oil pipeline, following a rigorous 13-day investigation led by Bangkok Governor Chatchart Sittipunt. The discovery of a 9 cm crack beneath the pipe cover has led to immediate repair efforts and plans for comprehensive inspections of all pipelines passing under expressway pillars.

According to Thai News Agency, Governor Chatchart personally inspected the site in Khlong Toei district, where oil contamination was detected in the drainage system near Chueapleng Road. The investigation revealed the crack at around 1:00 AM, with oil seeping from the pipeline, which is encased in a steel cover. The inspection process was challenging due to the need for non-sparking equipment to safely cut through the casing, which had accumulated oil residue.

Governor Chatchart explained that differential ground settlement around expressway pillars might have caused the pipe to bend and crack due to uneven pressure distribution. However, further investigation is required to confirm if this crack is the main point of leakage into the drainage system. Consequently, the Bangkok Metropolitan Administration (BMA) has temporarily halted the pipeline's oil flow and is closely monitoring safety risks.

The incident has prompted Governor Chatchart to initiate a city-wide inspection of all oil pipelines crossing expressway pillars, assessing both the pipelines' condition and environmental factors like ground subsidence. He acknowledged the collaborative efforts of officials and the Ministry of Energy, whose support was crucial in identifying the problematic points in the pipeline.

The pipeline plays a vital role in transporting oil from Chong Nonsi to various regions, reducing road transport and pollution. Governor Chatchart expressed relief at identifying the issue, emphasizing the importance of prompt repairs.

Ms. Thitiphas Chotidechachainant, Secretary to the Minister of Energy, disclosed that the Ministry's investigation team faced challenges due to the pipe cover's immobility. Bangchak Corporation has been instructed to employ a third-party company equipped with UT Scan technology to examine the pipeline for additional leaks. A recent scan identified another leak 1.2 meters from the pipe cover's end, measuring 6.6 cm long and 7 mm deep.

Repair efforts are underway, including the application of a repair wrap and subsequent testing to ensure the repairs are leak-free. An Intelligent Pigging Test will also be conducted along the 32 km pipeline to detect any potential risk areas. The Department of Energy Business has mandated that companies submit pipeline maintenance records and propose plans for pipe replacement and rerouting to prevent future leaks.
