Workers are returning to Gulf of Mexico oil rigs following Hurricane Michael.

The Bureau of Safety and Environmental Enforcement  (BSEE) said staff have returned to all 687 manned platforms.

Meanwhile drilling rigs which were moved away amid the storm have returned to position.

BSEE estimates 7.7% of oil production from the Gulf of Mexico remains shut-in following the storm and 3.5% of gas.

Since the storm has passed operators are now checking their facilities.

So far, three platforms have reported minor damage as a result of the hurricane.

Hurricane Michael is the first Category 4 storm in recorded history to make landfall in the northeast Gulf Coast.

At least 29 people across four southern US states have been killed.

Oil operator Chevron has announced it will pledge $500,000 to the relief effort.
