PTT Exploration and Production Public Company Limited (PTTEP) and its subsidiary, PTTEP Energy Development Company Limited, joined the 13th Thailand Oil and Chemical Spill Response Exercise (TOC-Ex13) organised by the Marine Department to enhance their ability to respond effectively to emergency situations. This annual activity was conducted in line with the draft National Oil and Chemical Pollution Management Plan. Its objective was to educate and boost preparedness among relevant government and private agencies for improved responses to marine oil spills. The exercise included a theoretical section with lectures on Thailand’s responses to marine pollution and a drill where participants undertook simulated emergency responses and a discussion-based Table Top Exercise. Prior to the 13th Thailand Oil and Chemical Spill Response Exercise, PTTEP, the Marine Department, Thai-MECC, and relevant agencies participated in the Oil Spill Preparedness & Response Training and Workshop in Bangkok and Songkhla provinces to bolster their preparedness and readiness.
