The Reliance Industries' MV Olympic Canyon, which has the capability of using high resolution cameras with ROV (Remotely Operating Vehicle) would arrive at the site at about 0600 hours on June 19 and commence search, Coast Guard Inspector General, Satya Prakash Sharma said here.
"This vessel also has the capacity of picking up any parts of the aircraft or lifting the aircraft from the sea...." he said.
"Sagarnidhi, which used high beam echo-sounder and sea bottom profiler, has not given us very many positive indication of confirming the position. Though they have received small echos in the same area where those beacon signals were picked up, there has not been confirmatory of these positions because the echo signal is very, very weak," he said.
National Institute of Ocean Technology (NIOT) scientists were not "very certain" of confirming the exact location of the aircraft at a depth of 700 metres, he said.

"Sagarnidhi will be 'vacating' the search area today and a naval submarine which was carrying out the search in other area would join the search operations in the 'most probable area' which has been narrowed down," he said.
The Naval submarine had earlier picked up intermittent signals from the aircraft's sonar locating beacon around the same position which was first established, he said.
About the delay in tracing the aircraft, he said, "it is purely because, we are not getting any confirmatory signals. It is because of the steep depth we have in this area. If it was a flat bottom, I am confident we would picked up the signal from the first day (of search operation) itself."
The plane with three crew members went missing on June 8 along Tamil Nadu's coastline during a routine maritime surveillance sortie.
