In 2003 a contract was signed with Seacore Limited (UK) to conduct the drilling operations for SHALDRIL.
The rig built for SHALDRIL is called the R-50 and is similar to that used on the recent IODP cruise in the Arctic. It is completely modular and can be rapidly mobilized as container freight. The rig has the capacity to take 100 m of core in up to 1,000 m of water and longer cores in shallower water. The SHALDRIL rig has a 3 m heave compensator that will allow drilling to continue in any type of seas in which people can realistically work. The rig will be mounted over the moonpool on the starboard deck. The position of the rig close to mid-ship will help minimize heave as compared to drilling over the stern. The moonpool will protect the drill string from stray bits of floating ice.
