SYSTEM DOCUMENTATION & REQUIREMENTS

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.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I design a subsea field layout in Python?▼

Call design_surf_layout with the field position, water depth, well counts, slots per template, reservoir dimensions, host offset, architecture, and design rates. It returns nodes, routed and sized lines, a summary, and a to_geojson() export for maps or GIS.

What flowline architectures does subsea layout screening support?▼

Three architectures are supported: dual_loop for round-trip-piggable paired legs, single_line for one dedicated line per drill centre, and daisy_chain for one line through all centres, which is flagged as not round-trip piggable.

Does the layout tool fetch bathymetry data from the internet?▼

No network connection is opened by default. The geodata module plans read-only requests to open sources like EMODnet, GEBCO, and Sodir FactMaps, and execute returns the plan as a manifest unless you supply your own fetch adapter.

Why are my flowline sizes coming out far too small?▼

The sizing expects actual volumetric rates at flowing conditions, not standard rates. Convert standard rates with the formation volume factor before passing them in, or the sizing is wrong by that factor.

What are the limitations of screening-level subsea layout design?▼

Routes are straight lines with no obstacle avoidance, crossing design, on-bottom stability, free-span, expansion, or mooring analysis. Wall thickness follows a fixed diameter-to-thickness ratio rather than a pressure design, so a qualified subsea engineering review is required.

Can the layout output feed a NeqSim production network model?▼

Yes. Each line provides endpoints, length, and inner diameter for PipeBeggsAndBrills or TwoFluidPipe, drill centres map to Mixer manifolds, and wells map to WellFlow inflow. Quantity take-offs also feed SURF cost estimation.
