PTTEP, in collaboration with the Department of Marine and Coastal Resources, the National Science Technology Development Agency, Kasetsart University Sriracha Campus, and independent inventors, has launched a Green Buoy for seawater quality monitoring project in 2020. The goals are to develop floating buoy technology to produce its own electricity from solar energy to monitor seawater quality and to enhance research capacity of ocean science and reduce dependency on foreign technology that is expensive and difficult to maintain.

The prototype Green Buoy was developed to be low-cost and equipped with sensors to automatically measure significant seawater quality parameters such as temperature, chlorophyll A, turbidity, and conductivity, etc. The seawater quality data is immediately transmitted and stored to the cloud that is connected to PTTEP Ocean Data Platform.

Furthermore, PTTEP is working on the development of a microplastic sensor to measure the amount of microplastic in seawater sample automatically, as well as developing the buoy to produce more electricity and increase its capacity for electrical energy storage system. This is to further the study and collect data on ocean science and underwater biodiversity.
