Safety

Oil and gas operators in the U.S. Gulf of Mexico have evacuated over 40 per cent of production platforms as a result of Tropical Storm Marco and ahead of the arrival of a second storm – Tropical Storm Laura.

The Bureau
of Safety and Environmental Enforcement (BSEE) said in an announcement on Monday
that the Hurricane Response Team was still monitoring the Gulf and the two
storms along with other state and federal agencies.

Based on data from offshore operator
reports personnel have been evacuated from a total of 281 production platforms,
43.7 per cent of the 643 manned platforms in the Gulf of Mexico.

The BSEE added that personnel have also
been evacuated from six non-dynamically positioned rigs, equivalent to 60 per cent
of the 10 rigs of this type currently operating in the Gulf.

A total of 11 dynamically positioned
rigs have moved off location out of the storms’ projected paths as a
precaution. This number represents 68 per cent of the 16 such rigs currently
operating in the Gulf.

As part of
the evacuation process, personnel activated the applicable shut-in procedure,
which can frequently be accomplished from a remote location.

This
involves closing the sub-surface safety valves located below the surface of the
ocean floor to prevent the release of oil or gas, effectively shutting in
production from wells and protecting the marine and coastal environments.

BSEE estimates that approximately 82.4
per cent of the current oil production and 56.92 per cent of natural gas
production in the Gulf of Mexico has been shut-in.

The BSEE added that, after the storms
have passed, facilities will be inspected. Once all standard checks have been
completed, production from undamaged facilities will be brought back online
immediately. Facilities sustaining damage may take longer to bring back online.
