JAKARTA, Sept 17 (Reuters) - Indonesian rescuers plan to try to right a passenger ship that capsized in the Java Sea last weekend as persistent strong currents and big waves prevent them from making an underwater search of the overturned vessel for the 129 people still missing.
The Virgo Transport 8 was carrying 243 people on a 20-hour voyage from Surabaya in East Java to Banjarmasin in South Kalimantan when it capsized in bad weather early on Sunday. Six people died and 108 survived the incident, tallies that have not changed since Sunday.
The national rescue agencyand Indonesian Navy will make an assessment on Thursday on the plan to turn the capsized ship back over, including what equipment was needed, the agency's chief MohammadSyafii told a press conference late on Wednesday.
"We plan to salvage the vessel by turning it upright and then conduct the search and evacuation. Once we are certain the operation is complete, the ship will be towed away for the investigation,"Syafii said, adding local and foreign experts had been consulted.
Turning the ship upright would normally take about 24 hours, but it could take longer if "there are complications," he said.
On Wednesday, two Navy teams started an underwater search but were forced to withdraw because the current was moving at nearly 7 knots,Syafii said, adding that diving is recommended only when the current is below 1.5 knots.
Some evidence discovered during the dives will be given to the National Transportation Safety Committee, which is investigating the incident, saidGalih Nurna Putra, the Navy commander inBanjarmasin, without providing further details of what was found.
Air and sea surface searches on Wednesday did not find any of the 129 people still missing, Syafii said. Similar air and surface searches will take place on Thursday.
The ship capsized around 80 nautical miles (150 km) from Banjarmasin port, andit has since moved around 450 metres (1,500 feet) and is in waters that are around 29 metres deep, Syafii said.
According to Indonesia's Maritime Law, the ship's owner is required to remove or tow it if it disrupts shipping lanes, he added.
