Tender mooring for infill drilling operations: A case study
The Tapis-pump platform is a four-leg jacket structure located 230 ft south of the Tapis-D platform and connected to it by a walkway bridge. All crude production (360,000 B/D) from Esso Production Malaysia Inc. (EPMI) wells in the South China Sea offshore Terengganu is piped to the Tapais-pump platform for pumping to an onshore terminal. The continuous operation of this platform is essential. The Tapis-D platform is a manned production platform that also acts as a central communication center and emergency response command center for EPMI`s offshore operations in the South China Sea. A total of nine wells is planned for an infill drilling program at the Tapis-D platform. The rig selected for this infill drilling program is a self-erecting tender-assisted rig that uses an eight-point wire rope mooring system. Eleven pipelines are connected to the Tapis-pump/Tapis-D platform complex. All the pipelines were laid on the seafloor without any special external protection and were not tied down or anchored. The paper describes the planning of the mooring system for drilling.
