The Songa Mercur semisubmersible drilling rig is currently off-hire in China resulting from structural failure of the telescopic joint, causing an uncontrolled descent of the BOP and Marine riser a short distance to sea bed on January 16, 2011. The Songa Mercur rig was not drilling at the time of the incident, and the BOP is in safe distance from the well, which had already been plugged and secured.
Songa Offshore foresees that all required resources are readily available in area for a safe and effective recovery. The incident is currently under investigation, and further updates to the recovery process will be issued when details and facts are available.
The on-going well was near its final stages at time of incident, and the rig had been planned to be towed to Singapore area after well completion in preparation for upcoming and future contracts.
The Songa Mercur was working for Eni on a one-well contract offshore Chin.
Henceforth, Songa Mercur does not foresee any significant cost impact to budgets and/or projections resulting from the incident.
The Songa Mercur is F&G 9500 design semisubmersible drilling unit, capable of operating in water depths up to 1,200 feet using a 18-3/4" x 15 ksi BOP with 21" OD riser.
