Siemens has received an order for the supply of two complete power packages for Statoil's two new semi-submersible drilling units – Cat D. Purchaser is Daewoo Shipbuilding & Marine Engineering Co., Ltd (DSME), one of the world's largest shipbuilders headquartered in Seoul, South Korea. The end customer is Songa Rig AS, the Norwegian branch of the drilling contractor Songa Offshore SE. The rigs will start their assignments for the operator Statoil in mid-water operations on the Norwegian Continental Shelf in 2014.
These new drilling units for Songa Rig are specially designed for Statoil for production and development drilling in fields with water depths between 100 and 500 meters, and are capable of drilling to depths of 8500 meters below the sea floor. The Siemens scope of supply for these semi-submersible units consists of electric generators, medium- and low-voltage switchgear and MCC (motor control center), distribution transformers as well as complete drilling drive line-up with cooling and braking resistor skids, thruster drives and motors and uninterruptible power systems. The system will be designed according to the latest rules and regulations for operating on the Norwegian Continental Shelf.
"Siemens was involved in the early stage design of the Cat D. drilling units. As a result of this involvement, we've been able to meet the stringent requirements and supply a complete integrated solution for these mobile offshore drilling units," said Adil Toubia, CEO of the Oil & Gas Division of Siemens Energy. "We're providing a uniform, seamless solution for our customer. This will enable the units to operate smoothly and achieve high operational efficiency, reliability while maximizing the operational uptime." Siemens also received orders for power solutions with a similar scope for a total of six drilling ships from DSME in the spring of 2011.
