PTTEP utilized its offshore operation area for the microplastic baseline study and monitoring to define the marine debris situation in the Gulf of Thailand, under the Memorandum of understanding (MoU) with Kasetsart University, to promote ocean sustainability. The project has started collecting seawater for microplastic study since 2020, which is the first such study in Thailand. It is also the world’s first attempt to use petroleum platforms as sampling sites. The project results will benefit ocean scientists and government agencies, so that they can better understand the ocean waste situation, then leading to the improvement of marine resources conservation.
