During the construction of the Central Cormorant Underwater Manifold Centre (UMC), it was recognized that the cuttings produced during the drilling of template wells would interfere with UMC operations, if deposited on top of the structure. A dual system was developed and installed on the Stadrill (the unit planned to drill the wells) to remove the cuttings from the rig to the seabed away from the UMC. The system as conceived and designed has been successful; it fulfills the requirements for flexibility, reliability, and efficiency. Its dependence on equipment external to the rig is minimal and after the capital outlay, the running costs are only for extra crew to operate the equipment and for maintenance. However, the system has been tailor-made for the UMC, the Stadrill, and the conditions prevailing in the Cormorant area.
