Trouble on Board the Transocean Marianas

Water ingress was noticed on board the deepwater semisub, Transocean Marianas, while preparing to move off location while working for ENI. Transocean says that the rig is stable at this time and no injuries have been reported. 108 non-essential personnel have been evacuated from the rig. Thirteen crew members have remained on board to monitor the situation. Transocean has launched its own investigation into the incident and is researching solutions to remedy the situation.

Unconfirmed sources have reported that rig developed a crack in one of the pontoons while picking up anchors.

ENI, which has the rig on a three-year contract at dayrate in the low-$450s, moved the rig to West Africa in late 2010 due to the deepwater moratorium in the Gulf of Mexico. The Transocean Marianas is an Earl & Wright Sedco 700 Series Enhanced semisub rated to work in water depths up to 7,000 feet. The rig was converted from a multi-service semisub (ex-Polyportia) and entered service as a drilling unit in 1998.
