Francine set for Wednesday landfall as hurricane

Tropical storm Francine is expected to become a hurricane today, as it continues on a path north through offshore US Gulf of Mexico oil and gas production areas on its way to a Louisiana landfall Wednesday.

Francine was located about 395 miles south-south west of Cameron, Louisiana, according to an 8am ET advisory from the National Hurricane Center. It is expected to remain off the coast of Texas and intensify to a Category 2 hurricane with winds of up to 100 mph, before landfall.

The storm will track through an offshore region that accounts for about 15pc of US crude output and 5pc of US natural gas production. Oil and gas producers started to evacuate personnel from offshore facilities earlier this week and shut in some production. Ports are starting to restrict traffic and offshore lightering operations were paused off of Galveston, Texas, starting Monday night due to high seas.

Shell said late Monday it was in the process of shutting in production at its Perdido platform after earlier pausing drilling operations from the facility located about 190 miles south of Houston. Drilling has also been suspended at its Whale facility, which is not scheduled to start operations until later this year. Non-essential personnel have been evacuated from Shell's Enchilada/Salsa and Auger assets, located about 120 miles south of Vermillion Bay, Louisiana.

Chevron initiated shut-in procedures for its Anchor and Tahiti platforms 190 miles south of New Orleans and began transporting all personnel from the facilities. Production from its other operated platforms in the Gulf of Mexico remained at normal levels. Non-essential staff were also being removed from the Big Foot and Jack/St. Malo platforms.

ExxonMobil said all staff had been transported off the Hoover platform, located about 200 miles south of Houston, and operations shut-in. So far, no major problems are expected at BP's offshore facilities in the region.

Ports in the northwestern Gulf of Mexico — including the Texas ports of Corpus Christi, Houston, Galveston, Texas City, Freeport, Beaumont and Port Arthur and the Louisiana ports of Cameron, Lake Charles and New Orleans — were set at port condition Yankee today, meaning gale force winds (39-54 mph) are expected within 24 hours and inbound vessel traffic over 500 gross tons is prohibited.

The US Coast Guard's captain of the port of Houston suspended lightering operations at the Galveston Offshore Lightering Area (GOLA) at 11pm ET Monday. Lightering, the process in which crude or refined products are transferred from one ship to another, likely will be delayed off the Texas ports of Corpus Christi and Houston until Thursday due to sea conditions.
