A 7 000 m Automated Drilling Rig System for Offshore Fixed Platform

To address the issues of low automation level， harsh working environment and high labor intensity of current offshore modular drilling rigs， an automated drilling rig system suitable for offshore fixed platform was newly developed. The drilling rig system is equipped with key drilling equipment such as dual driller ring network integrated control system， automatic horizontal catwalk， composite monkey board pipe racker， full hydraulic rotary table and five-cylinder mud pump for the first time on domestic platform， achieving automated transportation of pipes to/from drill floor， basic unmanned operation in drill floor wellhead and monkey board areas， and comfortable centralized operation in mud pump room and driller room. Field application results show that the supporting automation equipment effectively meets field operation requirements， significantly improving the working environment of personnel and greatly reducing labor intensity. The supporting dual driller integrated control system enables unified centralized management of drilling rig parameters and control， ensuring convenient and safe operation. The supporting five-cylinder drill pump achieves optimal operational performance while offering lighter total weight and more spacious field operation conditions， embodying a man-oriented operation and maintenance concept. The successful development and application of the drilling rig system provide reference basis and technical approaches for building new offshore modular drilling rigs and automation upgrading of aging platforms in the future.
