The following dive sites can only be reached by qualified technical divers carrying adequat certification and experience. The shallowest wreck lies in 58m of water and could be done on air for divers holding a technical diver (extended range) certification, though Trimix would be much prefered. All the other wrecks will ONLY be done one TRIMIX, the required certification level being Trimix (no entry level trimix).

Ocean Zone Divers vessel is the only technical dive boat in Phuket. She that carries a mixing facility, technical gear as well as Sorb and tanks for the rebreather divers. We visit wrecks every day, but the deep wrecks are visited according to the schedule.

These wrecks can also be visited by small groups of 3-5 divers on small chartered vessels of about 15m in length or by larger charter vessels (20m+) that can carry up to 10-15 fully equipped technical divers. In both cases, we need some notice to organise the vessel; 7 days for the smaller and 30 days for the larger.

This seems to be a small cargo ship of an overall length of about 40m. Recently a team from Deep Blue Divers found a plate of the shipyard and we can know presume taht it's the wreck of the Petaling.
The story says that it was sunk by a British submarine cruising the coasts of Phuket. The crew that survived the attack ended up drifting down to Kata Noi Beach, deported by strong currents. The story was related to us by an older Thai local who actually witnessed the attack and the final rescue of its crew.
The vessel now lies Off Kata Beach in 58m of water, flat on its keel with a slit list to port.
The status of the ship is now pretty broken down. The Rudder and propeller (4 pan) are still their as if time could not harm them. This wreck for some reasons has a number of portholes lying around it that do not match the actual size of the boat. Like most of the wrecks, this one has been colonised by schools of fish, Morey eels now live in the numerous cavity’s, and it’s not rare to spot rays lying on the surrounding seabed.
The dive profile needed to visit this vessel would be similar to 25’ bottom time on a TX 20/30, NX32 and NX70 or pure O2 as a last deco gas. The total dive time be less than 90’

The Vestal was a British Minesweeper of Algerine Class. Actually the very last Royal Naval vessel sunk during WWII. The identification is not 100% confirmed but due to its size and configuration, the odds of it being an other vessel are really very small. Algerine Class ship’s displaced 990 tons for a length of 65m (225ft), 10.6m at the beam (35ft) and a drag of 3.2m (10.5ft). The motors where steam engines that could give a maximum speed of 16 knots and an autonomy of 4 500 miles at 11, 5 knots. The armament was made of one 4 inch canon, 4 20mm canons and a Hedgehog mortar. The crew was made of 8 officers and a crew of 99.
The Vestal was hit by Japanese Kamikaze plane and finally scuttled due to extensive damage on the 26th of July 1945.
The ship now lies in 72m of water flat on its keel on a sandy seabed. The dive is a spectacular one. The amount of fish surrounding the wreck is terrific and this was also my first encounter with a tiger shark in Thai waters. The ship is now covered with nets which give it an exclusive mysterious flavour but also builds up the danger of entanglement. This wreck definitely deserves a few dives to get around it. The general status of it is good.
The proposed dive profile for this dive could be: 20-25’ bottom time on TX 16/40, Air and NX70 for decompression would get you out of the water in less than 95’

The CP 1238 was a towed catamaran transport barge. The overall length was about 50m, 8m at the beam and 6m high. At the time of writing we have no history of this vessel. All that we know is that the barge apparently sunk about 4 years ago. It transported cars that now lie on the seabed, surrounding the wreck but to far to be seen on the same dive.
The wreck now lies in 75m of water sitting straight up on a sandy seabed. The status of the wreck is excellent.
The visibility can range from 10 to 30m depending on the tide and the surrounding fishing activities. On the front deck lays what could be have been a life raft and closer to the stern two large 50cm diameter pipes and 4m long?
Big Carangids, Tunas, Barracudas, Morey eels, Lion fish and Scorpion fish have now invaded the barge. If you are lucky the encounter of a Manta Ray would not be impossible in the region.
The dive has no particular dangers except for the depth. A planning of 20-25min would be fine to get you all around it. A 16/40 mix, Air and NX70 profile of less than 90min

Not checked yet. Another project is a container carrier lying in 85m off Bang Tao. Again we have GPS points and will be checking them as soon as possible.

To be found. The HMS Squirrel (sister ship of HMS Vestal) probably lies off Racha Noi in 95m of water. We have GPS points at this day and while be checking them as soon as possible
