What problem does it solve? Concept studies need a subsea field layout before any drawing exists: how many drill centres and templates the well count implies, where the host and riser base should sit, which flowline architecture to use, and what size and length every flowline, riser, and umbilical should be. This Skill turns a well count, reservoir footprint, and water depth into a placed, routed, and sized screening layout. ## Core Features & Use Cases - Layout generation: Groups wells into drill centres and templates, places Xmas trees, manifolds, PLEMs, the riser base, and an FPSO or fixed host, each with latitude and longitude. - Routing and sizing: Routes production, injection, service, and umbilical lines under dual-loop, single-line, or daisy-chain architectures, sizing each against a target velocity and the API RP 14E erosional limit. - Georeferenced output and illustration: Exports WGS84 GeoJSON for maps and GIS, plans read-only requests to open bathymetry and licence-block sources (EMODnet, GEBCO, Sodir), and renders a reservoir-to-host cutaway carrying headline numbers as sourced KeyFact callouts. - Use Case: Given 8 producers, 6 water injectors, and 2 gas injectors in 400 m of water, generate a dual-loop layout around an FPSO, then hand node positions and line lengths to a NeqSim production-network model or a SURF cost estimate. ## Quick Start Ask the AI to design a screening subsea layout for your field by providing the well counts, reservoir dimensions, water depth, host offset, and design rates, and export the result as GeoJSON.
