In light of Hurricane Milton’s more southerly and easterly track, Chevron’s Blind Faith floating production unit is the only GoM platform reported to be shut-in at this time. Blind Faith was installed in 2008 in 6480′ of water in the Mississippi Canyon area, and is reportedly producing 65,000 bopd.

  1. Will Transocean be releasing any details on yesterday’s “water ingress?” Will the results of their internal investigation ever be made public? (We are still waiting for their report on the fatal crane incident last August offshore Nigeria.)
  2. Will an independent investigation be conducted? Will the authorities in Ghana participate?
  3. Did the damage that the Marianas incurred during Hurricane Ike (2008) or Tropical Storm Ida (2009) in any way contribute to yesterday’s apparent structural failure?
  4. When will we have an international system that ensures (a) prompt, independent, and complete investigations of all significant accidents, and (b) the timely release of findings?

Per Platts:

Deepwater driller Transocean confirmed that its semisubmersible rig Transocean Marianas operating off the coast of West Africa had taken on water early Wednesday, forcing the evacuation of some crew members.  “A water ingress was noticed onboard the Transocean Marianas during operations offshore Ghana” for Italian major Eni, Transocean spokesman Guy Cantwell said. “The rig is stable at this time. There are no injuries, and all non-essential personnel are being evacuated.”

This information is unconfirmed but the source is highly reputable:

We just received word this morning that the Transocean Marianas rig  has developed a large crack in one of the pontoons on the #5/#6 anchor chain locker while they were picking up anchors, and is currently taking on water and listing.  The bilge pumps are keeping up (barely), but there’s certainly concern that it might sink on location. So far, 68 people have been evacuated from location.

According to RigZone, the Marianas was working offshore Nigeria. [Per one of our readers, (see comment below) Petrodata shows the rig operating offshore Ghana.]

More:  The Marianas, spudded the Macondo in October, 2009, but was damaged by Hurricane Ida and towed to shore.  The Deepwater Horizon was the rig that replaced the Marianas.
