Adung said on Monday that the salvaging operation is progressing slowly because the Navy wants the warship to be pulled out of water with the minimal damage. He said the Navy wants to find out what caused the ship to sink.
The corvette-class vessel sank in a storm about 20 nautical miles (32 kilometres) off the coast of Bang Saphan district in Prachuap Khiri Khan on December 18 last year with 105 crewmembers on board. Of the 105, only 76 were rescued.
Adung said it would be extremely difficult to salvage a vessel from a depth of 50 metres in as complete a condition as possible.
