Shipping authorities are still to trace the route M V Pavit took to reach Mumbai following unfavourable weather conditions.
The grounded oil tanker had drifted from Oman coast to Juhu-Versova beach in July last year.
Officials said they failed to trace its route because of the weather conditions during June-August. They said the route would always remain a mystery.
We wanted to reconstruct the route with the help of satellite imagery,but at that time monsoon was prevalent and the entire area was covered with clouds. We are,therefore,not successful in tracing the route, said an official from the Directorate General of Shipping.
Also,no one even spotted this vessel drifting,else we would have alerted the authorities concerned,the official said.
