According to forest department sources, the investigation team, led by park director R C Pal, has submitted its report on the oil spill near the park on the Jamnagar coast, to Chief Conservator of Forests G A Patel.

The repair works on the sub-sea pipeline near IOC's SBM might have resulted in the leakage, Patel said.

Meanwhile, a senior IOC official told newsmen here that following the suspension orders, two crude vessels were lying anchored in the mid-sea since last four days.

He told newsmen, who were taken for a visit to the SBM, that IOC was incurring losses of US $25,000 per day.
