Singapore rig builder Sembcorp Marine said it has delivered the world's biggest jack-up rig to London-based Noble Corporation, for use in the North Sea.

The rig, called Noble Lloyd Noble, is the seventh ultra high-specification harsh environment jack-up rig successfully completed for Noble Corp.

The rig is capable of operating in a water depth of up to 150m in harsh environmental conditions. It boasts a maximum total drilling depth capacity of 10,000m.

To be deployed in Statoil's Mariner field development in the North Sea under a four-year charter arrangement, Noble Lloyd Noble is the first offshore structure of its kind to fully comply with both Norwegian and British regulatory standards, the company said in a statement to the Singapore Exchange last Saturday.

The Noble Lloyd Noble project achieved eight million man-hours worked without reportable incidents onboard the rig. It also scored a low accident frequency rate of 0.10 per million man-hours worked over a 31-month construction period.

Sembcorp Marine president and chief executive officer Wong Weng Sun said: "The Noble Lloyd Noble reaffirms Sembcorp Marine's ability to continuously scale new peaks as a manufacturer of the world's most sophisticated rigs."
