The province's offshore regulator sent a short tweet to signal some big movements at sea on Sunday.
The C-NLOPB, or Canada-Newfoundland and Labrador Offshore Petroleum Board, said two large oil rigs were taking evasive action against some equally massive structures off the east coast of Newfoundland.
"As a precaution, the Henry Goodrich and West Aquarius have safely disconnected from their wells due to approaching icebergs," the C-NLOPB stated on its Twitter account late Sunday morning.
Unlike oil rigs, the Hibernia platform is designed to resist the impact of sea ice and icebergs.
According to the Hibernia consortium, the gravity-based structure can withstand the impact of a one-million-tonne iceberg with no damage.
