Was a mention of this on Thai news this morning but not that it had sunk, just listing due to high winds and 4-5m swells in the Gulf.
However The Sun reports otherwise. the photos look fairly convincing
LOST AT SEA Huge search operation for dozens of sailors ‘in the water’ after warship rolls over and sinks in rough seas off Thailand

A FRANTIC rescue mission is underway after a warship sank during a powerful storm in the Gulf of Thailand.
The Royal Thai Navy said at least 28 sailors are still "in the water" waiting to be rescued after HTMS Sukhothai sank at 11.30pm on Sunday night.
Officials said Sukhothai was on patrol 20 miles from the port of Bang Saphan when it ran into choppy waters and took on water.
The ship's electrical system was wiped out, leading to engine failure.
Terrifying footage taken on board shows the vessel drifting on its side while crew members dressed in life jackets desperately holding onto a railing.
The Navy dispatched three ships to help - but only one could reach the scene before the warship sank.
