The Usumacinta Disaster
On Sunday, October 21st, 2007 the Usumacinta arrived in position next to the Kab-101 platform to finish the drilling of the Kab-103 oil well. Within three days onsite a cold front moved across the Bay of Campeche creating wind speeds up to 130 km/h and 8 meter waves. This storm caused the closure of eight separate ports in the Gulf for commercial traffic. These conditions were described by Carlos Morales, director of PEMEX’s exploration and production unit as “extreme weather conditions we’ve never registered before.” These operating conditions caused oscillations in the Usumacinta resulting in a collision of the cantilever deck of the Usumacinta and the top of the production valve tree of the Kab-101 platform, causing a leak in oil and gas at approximately 1200 hours on October 23rd, 2007.
Around 1420 hours the subsea valves of wells 101 and 121 were closed by PEMEX in order to stop the leakage of oil and gas. Unfortunately the valves were damaged in the collision and some leakage continued after these safety valves were closed. This resulted in an evacuation of the 81 crew members occurring at approximately 1535. On November 13th, a spark from on-going containment work caused a significant fire to ignite on the Usumacinta. This fire was put out on November 14th at approximately 2350 hours. A second fire occurred on November 20th causing immense damage to the Usumacinta platform including the collapse of its derrick and severe damage to the cantilever deck and connecting bridge.
This incident will be covered extensively with a focus on possible preventative measures that would have been put in place to avoid similar disasters from occurring in the future.
