Offshore, a fishing boat finds a Venus 14 sailor alive 30 nautical miles from the wreck. Five remain missing as the navy searches the Gulf. The sinking’s cause is unknown, with 280,000 litres of diesel aboard and 61 rai of reefs potentially at risk.
A sailor was rescued alive on Friday after the oil tanker Venus 14 sank off Sattahip, leaving five crew members missing in the Gulf of Thailand. Found 30 nautical miles from the wreck, he survived as rough seas hampered rescue operations. Meanwhile, the Royal Thai Navy intensified its search amid conflicting crew figures and an unexplained four-hour gap between lost contact and the emergency report. The cause remains unknown, while questionable tracking records deepen the mystery. Authorities also face a potential environmental emergency involving 280,000 litres of diesel and 61 rai of threatened coral reefs off Prachuap Khiri Khan.

A sailor from the sunken Thai oil tanker Venus 14 was confirmed rescued on Friday morning, November 13. A fishing vessel found him alive late Thursday night, approximately 30 nautical miles from the disaster site.
Five fellow crew members remained missing as the Royal Thai Navy intensified its search across the Gulf of Thailand. The tanker sank off Sattahip in Chonburi on Wednesday, reportedly carrying 280,000 litres of diesel. Meanwhile, authorities faced a second emergency involving possible fuel pollution along the Prachuap Khiri Khan coastline.
The Royal Thai Navy confirmed the rescue in reports published by Khaosod at 10.29 am on Friday. Further information released at 11.20 am identified the fishing vessel as Phon Nuchit 5. Its crew discovered the sailor at approximately 10.15 pm on Thursday, November 12.
Fishing boat finds missing sailor alive off Prachuap Khiri Khan as rough seas obstruct transfer ashore
The rescue occurred towards Khlong Wan, off Prachuap Khiri Khan, more than 40 hours after the reported loss of contact. However, strong winds and rough seas prevented the fishing vessel from entering Khlong Wan harbour.
In response, authorities arranged for the Marine Department’s pollution-response vessel Den Sutthi to transfer the survivor ashore. The latest available reports did not confirm completion of the transfer or disclose the sailor’s medical condition.
His identity also remained undisclosed, along with his account of the tanker’s final hours. Nevertheless, the discovery provided the first confirmed survivor since Venus 14 disappeared on Wednesday. It also gave naval commanders a new position from which to search for the remaining crew.
The rescue prompted an immediate adjustment to the search operation. Naval commanders concentrated vessels and aircraft around the waters where Phon Nuchit 5 discovered the sailor. In parallel, maritime search-and-rescue mapping was used to calculate possible drift patterns.
Five sailors remained unaccounted for according to the navy’s latest operational figures. No further rescues had been confirmed by Friday lunchtime, while authorities had announced no fatalities. The operation had entered its third day without an established cause for the sinking.
Sunken diesel tanker identified as Venus 14 as navy establishes its position southwest of Sattahip
Venus 14 was a Thai-registered coastal tanker supplying diesel to fishing vessels operating in the Gulf of Thailand. The vessel measured 32.5 metres long and 6.2 metres wide, with a registered gross tonnage of 199 tonnes.
According to the Prachuap Khiri Khan Marine Office, it belonged to Thai Laem Thong Fishing Oil Trading Company Limited. Its sinking triggered a major maritime emergency involving naval patrol vessels, surveillance aircraft and specialist response teams. Separately, environmental agencies began preparations for a possible release of its reported diesel cargo.
The Royal Thai Navy’s First Naval Area Command received notification of the sinking at approximately 9 am on Wednesday, November 11.
The reported position was near coordinates 12°20′N, 100°29′E, southwest of Sattahip Naval Base. Naval information placed the location approximately 27 nautical miles from the base’s navigation-channel entrance. The bearing was recorded as 227 degrees from Sattahip. However, the precise time the tanker went down had not been established.
Royal Thai Navy launches air and sea search for six sailors after tanker disappears off Chonburi coast
Rear Admiral Chanin Sriyabhai, spokesman for the Royal Thai Navy, initially confirmed that six crew members were aboard. Naval commanders immediately dispatched patrol vessel T.113 to the reported sinking position.
A Dornier Do 228 maritime patrol aircraft was also deployed to search the surrounding waters. Additionally, navigational warnings were issued to other vessels operating in the area. The initial response produced no confirmed survivors, leaving naval personnel searching open waters around the tanker’s last reported position.
By Thursday, November 12, the operation had expanded to include maritime security personnel, special operations teams and Marine Department vessels. The Maritime National Interests Protection Centre Region 1 coordinated with the First Naval Area Command.
Rear Admiral Wasan Traijit, commander of the First Naval Area Command, was reported to be directing the operation. At that stage, no sailor had been located. The navy continued searching while attempting to establish the vessel’s final position and circumstances of its disappearance.
Orange life jacket recovered near sinking site before fishing vessel finds first survivor alive at sea
A significant discovery came at approximately 3.20 pm on Thursday. A naval patrol recovered an orange reflective life jacket floating near the reported sinking coordinates. The equipment carried the marking SOLAS-XT1800B1*0525/2022. Investigators retained the jacket for examination, although its connection to the missing sailors remained unconfirmed.
No crew member was found with it. Notably, authorities had not established whether the equipment had been deployed during an evacuation.
The life jacket was among the first reported physical items recovered during the search. However, it offered no confirmed explanation for the vessel’s disappearance. Investigators had not established whether the crew abandoned the tanker together or became separated.
Nor had they disclosed the availability or condition of other survival equipment. Several hours later, the discovery of a sailor alive off Prachuap Khiri Khan changed the direction of the operation.
Phon Nuchit 5 found the survivor approximately 30 nautical miles from the original sinking position. Consequently, naval commanders redirected attention towards the rescue location and surrounding waters.
Naval search shifts towards rescue site as conflicting reports leave the original crew count unresolved
Search-and-rescue calculations were being used to examine possible movements of the remaining sailors. Yet authorities had not established how the survivor reached that position. His movements after the sinking remained undisclosed, as did the circumstances in which the fishing crew discovered him.
The rescue also exposed a discrepancy in the reported number of sailors aboard Venus 14. The Royal Thai Navy consistently stated that six crew members were missing following the sinking.
However, a local source on November 12 cited Marine Office information indicating seven missing sailors. The difference remained unresolved in Friday’s reporting. The navy nevertheless maintained its original count, reporting one survivor and five crew members still missing.
Authorities had not released a complete crew manifest or publicly identified the missing men. As a result, the discrepancy between the navy’s figures and the Marine Office information remained unexplained.
No official clarification established whether the higher number reflected an additional sailor or inaccurate initial reporting. The navy’s latest operational account continued to use six as the original complement. No fatalities had been officially confirmed by Friday lunchtime.
Four-hour gap emerges between loss of contact with Venus 14 and navy receiving the sinking report
Further information from the Marine Office revealed an earlier timeline for the tanker’s disappearance. According to Matichon, the operating company lost contact with Venus 14 at approximately 5 am on Wednesday.
The First Naval Area Command received notification of the sinking at approximately 9 am. That left four hours between the reported loss of contact and the naval emergency notification. However, the available accounts did not explain the interval or establish when the vessel actually sank.
The distinction leaves an important gap in the official sequence of events. The 9 am report established when naval authorities received notification, not the verified time of sinking. Meanwhile, investigators had not disclosed the vessel’s final communications or confirmed whether its crew transmitted a distress call.
No official account established when trouble began aboard the tanker. Likewise, the condition of the vessel immediately before contact was lost remained undisclosed.
Cause of tanker sinking remains unknown as tracking records reveal gaps and questionable AIS positions
The cause of the disaster was still undetermined on Friday. Investigators had not established whether Venus 14 suffered flooding, structural damage, machinery failure or a collision. Severe weather had not been confirmed as the cause.
Although rough seas subsequently complicated the rescue, their role in the sinking remained unknown. Authorities had released no findings concerning the sequence of events that sent the tanker to the seabed.
Additional details emerged from specialist maritime publication The Maritime Executive on Thursday, November 12. Its report examined automatic identification system records associated with Venus 14.
According to the publication, tracking information showed the vessel stationary near the position where it subsequently sank. The tanker had reportedly been broadcasting an at-anchor status when last detected, three days before the disaster.
The available records suggested Venus 14 had remained around the same location since at least late October. However, its AIS history contained unusual gaps and implausible recorded positions. These irregularities raised questions about the reliability of the tracking information. They did not establish wrongdoing or explain the sinking. Consequently, the vessel’s precise movements immediately before the disaster remained unclear.
Crew evacuation remains unexplained as agencies assess potential threat from 280,000 litres of diesel
Investigators also lacked a confirmed account of the crew’s final actions. No official findings established whether the sailors received sufficient warning before the tanker went down. Authorities had not disclosed whether life jackets or other survival equipment were deployed.
Similarly, they had not confirmed whether the crew entered the water together. The rescued sailor’s account had not been released, leaving the circumstances of the evacuation unknown.
On another front, the sinking created a potential environmental emergency involving the tanker’s reported diesel cargo. Venus 14 was believed to be carrying approximately 280,000 litres of fuel when it disappeared.
The Department of Marine and Coastal Resources began monitoring the possible consequences of a release. At the same time, the Royal Thai Navy and Marine Department prepared containment equipment. No diesel leakage had been confirmed in the latest available assessment.
The Geo-Informatics and Space Technology Development Agency, known as GISTDA, examined how escaping diesel could move through the Gulf. Its modelling indicated that fuel could initially drift southwards before turning west or southwest.
Consequently, coastal waters off Prachuap Khiri Khan were identified as a potential exposure area. The projections included coral reefs in Prachuap Bay, where several locations could be affected if diesel reached the coast.
GISTDA identifies 61 rai of coral reefs potentially exposed as navy prepares emergency spill response
According to GISTDA’s assessment, approximately 61 rai of coral reefs could be exposed under the projected scenario. The largest area was around Ko Rad, accounting for 25 rai. Another 15 rai lay near Khao Lom Muak, while Ko Lak accounted for 11 rai. In addition, six rai around Ko Rom and four rai near Ko Haim were included. Together, the five locations represented the projected 61 rai of potentially exposed reefs.
Crucially, the figures represented possible exposure rather than confirmed environmental damage. Authorities had not reported diesel reaching the reefs by Friday lunchtime. Nor had they confirmed any fuel discharge from the wreck.
The modelling therefore remained a contingency assessment based on possible pollution movements. Environmental personnel continued monitoring the surrounding waters while preparing for containment operations if a leak developed.
The Royal Thai Navy placed additional vessels and specialist equipment on standby for a possible spill response. These included HTMS Panyi, helicopters, response crews and oil dispersal equipment.
The Marine Department was also coordinating arrangements for containment and clean-up operations. Furthermore, naval authorities were monitoring the wreck’s position while maintaining the search for survivors. The reported diesel cargo remained a separate concern as the maritime emergency continued.
Naval rescue and pollution teams face twin emergencies after another sinking off Thailand’s eastern coast
The operation required resources for both the missing sailors and the potential pollution threat. Naval vessels and aircraft concentrated on search operations, while environmental agencies monitored the sinking area. Meanwhile, Marine Department resources were also needed to assist the rescued crew member.
Den Sutthi was assigned to transfer him ashore after Phon Nuchit 5 encountered rough conditions near Khlong Wan. The latest reports did not confirm completion of that operation.
The Venus 14 sinking followed other serious maritime accidents off Thailand’s eastern coastline. In September, a fishing boat sank off Sattahip, killing three crew members and leaving four others missing. Earlier this week, a separate collision occurred off Pattaya when a speedboat struck a fishing boat. Nine people were injured, including Thai and foreign tourists. Those injured reportedly included a Ukrainian woman and two Russian women.
However, neither earlier accident had been linked to the Venus 14 disaster. The incidents involved separate vessels and circumstances. The latest sinking nevertheless required another major naval response in waters off Chonburi.
This operation involved a fuel tanker, missing sailors and preparations for a possible diesel spill. The cause remained unknown, while investigators continued examining the vessel’s final movements and the circumstances of its disappearance.
Five sailors still missing on Friday as sinking cause, crew numbers and diesel leakage remain unresolved
By 12.30 pm on Friday, November 13, the navy’s confirmed operational position remained one survivor and five missing sailors. No fatalities had been announced.
The discrepancy concerning the original crew count remained unresolved, alongside the exact sinking time and cause. Authorities had also not confirmed any diesel leakage. Meanwhile, the survivor’s identity, medical condition and account of the disaster remained undisclosed.

The rescue provided the first confirmed breakthrough since Venus 14 disappeared on Wednesday. One sailor had survived after being found approximately 30 nautical miles from the reported sinking position.
However, five others remained unaccounted for as the search entered its third day. Naval personnel continued concentrating on waters around the rescue location, using drift calculations to guide the operation. Separately, environmental authorities monitored the wreck and its reported 280,000 litres of diesel.
