For the past six months, carrier NITC (National Iranian Tanker Company) has worked to prepare for the day when the West would lift the sanctions against the country. During this time, NITC has negotiated with foreign organizations for the classification of vessels, insurance for incidents including oil spills, as well as international registration, and a deal is close to being made, said Nasrollah Sardashti, director for commercial affairs, on Tuesday, according to Bloomberg.
