NN field 01 development initial phase of Wellhead platform offshore · 模型 5081
An offshore wellhead platform is a fixed or minimal structure installed above underwater oil and gas wells to house production trees, control systems, and safety valves. It acts as the surface junction for downhole drilling strings and channels extracted hydrocarbons through subsea pipelines to larger processing facilities or central production platforms. Core Functions and Systems : Well Control: Supports surface Christmas trees, choke valves, and downhole safety barriers to regulate high-pressure fluid output. Safety Integration: Features emergency shutdown systems (ESD) tied to high/low pressure sensors to automatically isolate wells during emergencies. Routing and Testing: Manages production manifolds and test separators to monitor individual well performance and direct flow. Structural Designs - Conventional Jacket Structures: Four-legged steel lattice frames secured to the seabed with driven steel piles, designed for standard water depths and multiple well slots. - Cost-effective, single-column structures built for marginal or shallow fields, supporting lightweight decks and a limited number of wells. - Unmanned Configurations: Automated installations powered by solar energy that operate remotely without permanent crew quarters, receiving periodic maintenance visits via boat or helicopter.
