"The government machinery including the Indian Embassy in Tehran, Ministries of Shipping and External Affairs are trying to convince the Iranian authorities that no pollution was caused by the vessel but unfortunately there is no progress," a Shipping Ministry official told PTI today.
A top official of the Shipping Corporation of India (SCI) also said that "efforts by an Indian team, which was camping there, to convince Iranian authorities that no pollution was caused by our team have failed to make any impact so far."
A team which included a surveyor from Indian Register of Shipping, which is an internationally recognised independent ship classification society founded in India in 1975, and a senior SCI official was sent by the Director General of Shipping to Bandar Abbas port to inspect the vessel.
The team had after inspection verified that no pollution was caused by the tanker with a capacity to carry 1,40,00O tonnes of crude.
He added that the ministry was working towards successful outcome of the "delicate" situation.
The Iranian authorities had expressed environment concerns and alleged that the vessel was causing pollution, a charge denied by Indian officials.
