Big Blue Tech - Koh Tao - Thailand                                                             Facebook  Twitter  GooglePlus

This cargo essel sank during a typhoon in 1989. Local Koh Tao inhabitants said that the ship just pulled up off shore, around a mile North of Koh Tao 'Mango Bay' and over the next couple of hours slowly sank. No-one was hurt in the sinking, and an insurance fraud was immediately suspected.

A commercial Diving company was hired by the vessels insurance investigators to investigate the cause of the sinking and to confirm the cargo. which was listed as expensive Tuna Fish. Divers descended to examine the wreck, and discovered that the holds contained nothing but low-grade animal Feed (Dog-Food) un-fit for human consumption, NOT expensive Tuna fish as listed on the manifest!

The wreck is that of a large modern 1960-70s, 60 metre long steel freighter lying stern-down on the bottom at a depth of 50m. The vessel leans slightly on its port side an angle of 60 degrees, with the top of the bow at 38 metres, and the keel of the bow area several meters above the seabed, allowing divers to swim under this area of the hull. Lots of penetration points were available when it originally sank for technical divers highly experienced in diving in conditions where a total silt-out may occur. But nowadays it is considered too dangerous to even attempt to penetrate.

By way of warning, there have been a number of serious DCS injuries to even experienced recreational scuba divers who have attempted to dive this wreck without proper 'technical diver' training. One French couple having got completely disoriented in a narcosis enhanced 'black silty cloud of death' ran out of air and bolted to the surface...missing all their deco. One of this 'buddy pair' suffered severe DCS which did not respond to treatment is now languishing paralyzed in a wheel chair back in France. The wreck when first discovered was covered in several large fishing nets which have all since been removed by local tech divers.
