Extreme IT: Hurricanes, High Winds and Heavy Seas

When Lance Gibson talks about a storm knocking out his systems, he doesn't mean the infamous worm. He might be referring to the latest hurricane to sweep through the Gulf of Mexico or to the lightning accompanying a vicious thunderstorm.

Gibson is the offshore infrastructure communications supervisor for Chevron Corp.'s oil fields in the Gulf of Mexico, overseeing the IT needs of the company's offshore production facilities as well as its onshore support centers.

"Basically, I'm responsible for the entire infrastructure delivery," he says, "from the servers onshore all the way to the microwave, wireless and satellite communications we use for our voice and data communications offshore." We spoke with Gibson in mid-August; joining the conversation was Chevron public affairs representative Qiana Wilson.

A couple of weeks after our conversation, Hurricane Gustav provided a dramatic reminder of the kinds of situations Gibson has to deal with. Chevron and other companies with facilities in the Gulf evacuated their workers and shut down their oil platforms in advance of the threatening storm.

Once Gustav passed, Chevron began assessing its facilities and planning on remobilization of personnel, but Hurricane Ike put an end to that and forced another evacuation. At the time of this writing, Chevron reports that although several of its platforms were toppled by the storms, the company has once again started remobilizing its personnel.

Where are the offshore oil facilities that you support?

Gibson: We support the entire Gulf of Mexico region, from offshore Texas to offshore Alabama, whether our operations are on the OCS [Outer Continental Shelf] or in the deepwater areas of the Gulf of Mexico. That includes all of our offshore production platforms and drilling rigs, as well as our onshore operations that pertain to our Gulf of Mexico business units.

[Editor's note: The Gulf measures about 1,000 miles east to west and more than 500 miles north to south from Louisiana to the Yucatan Peninsula.]

How many installations are there?

Wilson: We don't like to say how many offshore installations we actually have. But I can tell you that Chevron is the largest leaseholder in the Gulf of Mexico shelf.

How far offshore is the farthest one?

Wilson: Right now, the farthest offshore is [the platform named] Genesis, which is about 150 miles from New Orleans. When Tahiti and Blind Faith come online, they'll be still further out and in deeper water.

How deep?

Gibson: The water depth can range from 10 feet near the shore all the way to 3,000 or 4,000 feet in the deeper waters. We're constantly moving out deeper.

How many people work on each platform?

Wilson: It varies from platform to platform; we don't really like to divulge that information.

Do you travel around from platform to platform, or are you stationed on land?

Gibson: I'm stationed on land -- my home office is here in Lafayette, Louisiana. My group is primarily stationed on land also.

We take a tiered, or layered, approach to support. We do most of our troubleshooting "on the beach," and if we cannot resolve the problem, then we'll dispatch one of our technicians offshore. But we try to do most of our support from onshore, to save money.

What's the communications setup on the platforms?

Gibson: A typical facility will have a wireless LAN installed, with all your standard network gear -- routers and switches and all that. And then they have microwave and VSAT [ Very Small Aperture Terminal ] satellite communications systems. But we house our servers on land, in either our Lafayette or Covington [Louisiana] locations.

What kind of data travels over your network?

Gibson: Mostly your typical business data -- Microsoft Word, Excel, that sort of data. And then we have specific application data -- real-time drilling information, automated monitoring of the status of the platform and so on.
