Thai aircraft and ships were searching for dozens of missing sailors after a Royal Thai Navy ship capsized and sank in rough seas off Prachuap Khiri Khan province, officials said Monday.

Seventy-five sailors have been rescued but the search in Gulf of Thailand waters was going on for at least 31 others from the HTMS Sukhothai despite strong winds and high waves hampering the operation, a Navy spokesman said Monday. It was the first sinking of a Thai navy ship in nearly eight decades dating back to World War II.

The ship’s engines and power generators failed after suffering severe flooding while being struck by 2- to 4-meter (6.5- to 13-foot) waves about 20 miles off shore on Sunday, officials said.

“We don’t give up on the search around the sunken spot. No one has been found dead so far,” Navy chief Adm. Choengchai Chomchoengpaet said Monday. “The Navy has dispatched war ships and aircraft, while the Air Force has sent helicopters and planes to search for them.”

“Preliminary, the injured said there was an influx of sea water and they tried to fight,” Choengchai said, adding, “but the rough weather led to more flooding causing the ship to lose generators and engines.”

A Navy spokesman, meanwhile, said a round-the-clock rescue operation was ongoing.

“We have rescued 75. The missing remains at 31. Though it is dark now, we will search for them all night,” Navy spokesman Adm. Pokkrong Monthatphalin told BenarNews, an RFA-affiliated news service, on Monday evening.

As the Sukhothai was listing on Sunday, the Navy sent another ship to rescue the crews but could not get near it, officials said.

A non-commissioned officer on board the Sukhothai told local Thai media that the waves were as high as 5 meters (16.4 feet), as the frigate HMS Kraburi sailed nearby.

“The waves were so rough, the crews scattered around the decks and waited for other ships to come help but to no avail. We waited until our ship sank and they could help us,” Petty Officer Second Class Patarawut Maram said.

“Since setting sail for two years, I have never encountered such strong winds. The waves came in at once, four to five meters high, crashing until it hit the side of the boat,” he said.

“Some people fractured their ribs,” he said, adding, “we had to wait until our ship sank first, then another ship could come to help.”

A doctor in Prachuap Khiri Khan said 15 were treated for injuries including three who suffered broken bones.

Pokkrong, the Navy spokesman, said a cargo ship had sunk over the weekend in nearby waters.

Poor weather forecast

In its Monday forecast, the Thai Meteorological Department reported that poor conditions were expected to remain in the region.

“[The] northeasterly monsoon blanketed the Gulf of Thailand, southern Thailand and the Andaman Sea remains strong, causing heavy rains. In both the Gulf and the Andaman Sea, the waves are as high as 2 to 4 meters and above 4 meters in the rainy areas,” it said. “Boats should sail with caution and avoid the rainy stormy areas until Dec. 20.”

Designated FSG-442, the Sukhothai is one of the two Royal Thai Navy corvettes built in Tacoma, Washington. Commissioned 35 years ago, it was capable of conducting surface-to-air, surface-to-surface and anti-submarine warfare.

The sinking was the first of a Thai warship in 77 years.

Bangkok media reported that the HTMS Samui sank after being struck by a U.S. torpedo near Malaysia in 1945, killing 31 sailors. Four years earlier, the French Navy attacked Thai ships during the Franco-Thai War, sinking two ships and heavily damaging a third.

Snowball.

Sunday 18-12-22, CustomWeather reports for the Gulf of Thailand: 26 deg Celsius; clear view; windspeed 16 - 32 km/h. Weather report service "Windy" stated a wind speed of 44 km/h. Which is equal to windforce 5 - 6 Beaufort, that's not a storm. The Thai Navy said that the wave heights during this disaster were 3 - 4 meters (10ft - 13ft 2").
Out of personal experience, I know that in this area during severe rain showers, this kind of wind can turn into a locally (strong) storm. HTMS Sukhothai was not the only victum. The 122 meter long container coaster MV Suntud Samut 2 sank in the same area at the same day.

1400 hrs: HTMS Sukhothai reports a flooding.

1600 hrs: The Sukhothai reports a brief on-board fire.

1645 hrs: Sukhothai reports to shore base, that it wants to return to port. Because of flooding and engine troubles.

1716 hrs: Seawater enters HTMS Sukhothai.

1803 hrs: Sunset, the corvette is listing 45 deg to port side. Smoke comes still out of the engine chimney's. A group of crew members gather at deck wearing their lifevests.

1817 hrs: Engines have stopped and power black-out, listing is increasing.

1900 hrs: Sukhothai requests tow boats, while 16 nm out of the coast, close to Prachuap Khiri Khan.

2000 hrs: Listing increased to 60 degrees, crew is trying to pump out water.

2024 hrs: several Thai ships are send out to rescue crew of HTMS Sukhothai.

2109 - 2124 hrs: A heli arrives, a lot of crew sitting at the starboard wall of the superstructure. Ship listed at 60+ degrees.

2136 hrs: HTMS Kraburi comes side by side, in order to try to speed up the rescue of the crew.

2251 hrs: Kraburi has still not rescued everybody, due to high waves.

2320 hrs: A part of the Sukhothai crew can still not make the trasnfer to HTMS Kraburi, because of high waves.

2330 hrs: HTMS Sukhothai sinks.

The Thai Navy stated quickly after the sinking, that the flooding occured via an exhaust. This is not the main engine exhaust (chimney), but an exhaust of engine or diesel gensets cooling water close to the waterline. If the piping of this cooling water breaks and you cannot operate the main valve, a lot of flooding can occur.

The Thai TV channel PPTV HD 36 interviewed one of the survivors. He said the flooding came from the bottom of the ship. They tried to pump out the water for 1 - 2 hours, before the engines blacked out.

This is a 35,5 year old ship. After a service time of approx 15 years, the need for maintenance of a seagoing ship goes up up structually. There are unconfirmed reports about inadequate maintenance and training.

Accidents are always caused by different factors at the same time. The snow ball effect.
