Why did Transocean upgrade its Sedco 700 rigs?

FROM THE FULL PICTURE MAGAZINE -- To meet market demands for deepwater drilling, Transocean chose to upgrade two of its Sedco 700 series drilling rigs to dynamically positioned class 2 semi-submersible rigs. The process was so comprehensive the rigs were classified as newbuilds.

Who built the Sedco rig?

Two of the drilling platforms, the Sedco Express and the Sedco Energy, were built by DCN in France. PPL Shipyard in Singapore built the third rig, the Cajun Express.

What is a DP class 2 semi-submersible rig?

The aim was to retrofit her into a dynamically positioned (DP) class 2 semi-submersible rig, capable of operating in moderate environmental conditions and in water depths down to 6500ft. In order to achieve this, major structural works were carried out, including a pontoon and column extension in order to contain more drilling fluids.
