Both KCA DEUTAG and RDS have been closely involved in the design of platform drilling rigs since the early days of the North Sea and this still forms a major part of our workload. Today, our market is very much international, with designs ranging from simple, fit-for-purpose manual rigs to powerful, heavily mechanised facilities that can deliver world class drilling performance.
