The contract for the two category D rigs is worth approximately $2,47bn, and the fixed charter period is for eight years per rig, with four three-year options.
Capable of operating in 100m to 500m of water, this specially designed category D drilling rig can drill wells down to 8,500m.
Songa has assigned the rig construction work to the DSME yard in South-Korea, and Aker Solutions will supply the drilling equipment.
The rig hand-over is scheduled for the second half of 2014, Statoil said.
