The gas field is located in the Gulf of Thailand about 140 km offshore of Nakhon Si Thammarat province.

 

During routine operations on October 19, 2019, workers spotted a young whale shark, approximately 16.4 feet (5 meters) long, in distress close to the Erawan-A platform.

A long, thick rope was wrapped around the whale shark’s tail. It is believed the rope came from having been entangled in a fishing net.
