The 3,200-dwt Srikandi-515 (built 2013) was pushed ashore off Narathiwat over the weekend after it dragged its anchor.

The vessel's stern has been swamped by the sea and oil has started washing up on the beach, the Bangkok Post reported.

The tanker is carrying 2.7m litres of palm oil.

Attempts to salvage the ship over the last three days have failed due to strong winds and big waves.
