The annual expo takes up the entire floor of Reliant Center, showcasing the latest in oil and gas technology – from drilling hardware to production pumps.
Safety equipment is also on display, including an oil platform escape pod that can be fully loaded in under 90 seconds.
"We are inside one of SSI's 60-man escape capsules," said James Ziegel with Survival Systems International. "Basically, it's a lifeboat for the oil and gas industry."
Ziegel says the lifeboat can be quickly lowered by a single cable into the water, at which point the cable is detached and the motor is powered up. There is enough food and water on board to keep all 60 people alive for a week.
The OTC runs through Thursday. Attendance is pegged at more than 80,000 people hailing from as many as 100 different countries.
