Analysis of operation of three rigs equipped with motion compensators indicates a saving of about 16 days per rig year. This is achieved by increasing the drilling limitation to 30-ft seas, which represents a net saving of $400,000 per rig year. Strain gauge monitoring found hook-load variation to be within 2.5 percent for rig heaves of 10 ft or less with the equipment working in the passive mode. Optimum bit loads allow maximum penetration rates and increased bit life, producing further savings of $600,000 per rig year. Other advantages such as safety in well killing and BOP-stack handling are discussed.
