Daewoo Shipbuilding & Marine Engineering (DSME ) has won an order worth about $1.1bn to build two semi-submersible rigs for Norway-based Songa Offshore .

The rigs will be 116m long, 97m wide and equipped with dynamic positioning systems for deep sea operations.

The rigs will also be fitted with positioning mooring systems, helping them to keep the same position in shallow seas to drill at a water depth of 500m.

Following delivery, the rigs will be chartered to the Norwegian state oil company Statoil and deployed to the Norwegian coast, the North Sea and Polar regions.

DSME has secured orders for 42 vessels this year, as well as offshore platforms worth $10.5bn.
