The Jolliet TLP is moored by vertical tendons and supports a compact topsides facility designed for processing production from subsea wells. The installation handles multiphase flow from multiple subsea production wells, with initial separation into oil, gas, and produced water streams. Oil is stabilized onboard and exported via pipeline, while associated gas is compressed for export or used as fuel gas. Produced water is treated before discharge. The facility includes gas compression systems, separation trains, and basic dehydration capability. Power generation is provided by gas turbines using produced gas. The platform is connected to subsea infrastructure via flowlines and risers, with control systems managing well flow remotely. The design emphasizes minimal footprint and weight, typical of early deepwater TLPs. Export pipelines link the installation to regional Gulf of Mexico infrastructure networks, enabling integration with onshore refining and gas transmission systems.
