The accident with a drilling rig that overturned in the Sea of Okhotsk killing at least two people poses no threat to the environment, the regional emergencies service said on Sunday.
"Fuel stocks at the Kolskoye drilling rig are minimal and are stored in hermetically sealed tanks, and there is no danger of a fuel spill," Taimuraz Kasayev, a spokesman for the regional emergencies service, said.
