THE DEEPWATER PIPELINE SYSTEM ON THE JOLLIET PROJECT

The paper describes the design and installation of the deepwater pipeline system which transports the oil and gas production from Conoco's Jolliet Field in the Gulf of Mexico. This pipeline system uses 12 miles of flexible pipe and 42 miles of conventional rigid steel line pipe. The pipeline system has pipelines in water depths from 230 - 1760 feet. The paper describes the installation of flexible pipe risers at the TLWP, the laying of flexible pipe through rough seafloor conditions, the installation of rigid steel pipes in 1400 ft. water depth and a seafloor connection system to facilitate tie-in of future production.
