"Thai Oil rush to contain 20-ton crude oil spill 9km from Koh Sichang", 6 June 2025

Government officials and private companies are working to control damage from a crude oil spill at Single Buoy Mooring-2 (SBM-2) of Thai Oil’s refinery in Sri Racha, Chonburi, during oil transfer operations from the Singapore-flagged vessel Phoenix Jamnagar. The incident occurred approximately 13km from shore and 9km from Koh Sichang island in 30-meter-deep waters.

Thai Oil Public Company Limited issued a statement explaining that the spill was caused by force majeure conditions from sudden high waves and strong winds just minutes before midnight on June 5, while workers were halting oil transfer operations according to standard safety procedures.

“The company had already deployed booms before crude oil transfer operations. Currently, there is no additional oil leakage, and the SBM-2 buoy system sustained no damage,” Thai Oil stated. “Oil slicks on the sea surface resulted from high waves and strong winds causing some oil to escape from the boom line. No injuries occurred from this incident.”

Government Response Mobilized

Deputy Transport Minister Manaporn Charoensri ordered Marine Department Director-General Krichphet Chaichuay to establish a coordination center for preventing and eliminating marine oil pollution. The Marine Department coordinated with the Royal Thai Navy to set up an incident command center for oil spill cleanup.

Area surveys revealed thin black or brown oil slicks scattered across approximately 100 square meters, moving southward at 1 knot with northeast winds.
