A force majeure notice was delivered to the government of Ghana and Ghana National Petroleum Corp. after an anchor- handling accident damaged the rig, Dallas-based Kosmos said today in a statement. The Marianas was scheduled to arrive July 10 for drilling, Kosmos said.
Kosmos said it anticipates that either the Marianas or a substitute rig will be “available soon” to drill the Cedrela-1 well in the West Cape Three Points Block. Transocean, based in Vernier, Switzerland, reported yesterday it evacuated 108 of 121 workers on the rig after it took on water while preparing to leave an Eni SpA drilling site off Ghana.
The market for deep-water rigs in that part of the world is so tight that Kosmos will likely have to wait at least a month for a comparable drilling vessel, said Brian Uhlmer, an analyst at Global Hunter Securities in Houston. Moving an unused rig from the Gulf of Mexico could take about 45 days.

Transocean Marianas questions
Posted in accidents, drilling, offshore, tagged accidents, evacuation, Ghana, list, Transocean Marianas on July 7, 2011| 1 Comment »
- 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.)

- Will an independent investigation be conducted? Will the authorities in Ghana participate?
- 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?
- 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.”

Per information provided by one of our readers (see comment on the original Marianas post), the rig was in transit offshore Ghana, west of Takoradi. This report indicates that “they have got control over the list at the moment.”
