SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Early subsea tie-back studies need a fast, public check of whether a step-out distance and estimated arrival pressure stay within simple guidelines before committing to detailed flow-assurance and hydraulic design. ## Core Features & Use Cases - Step-Out Screening: Compares a tie-back step-out distance against a configurable public guideline (default 50 km) and returns ok, watch, or high warnings. - Arrival-Pressure Margin Check: Computes the margin between estimated and minimum required arrival pressure and classifies its severity. - Optional Hydrate Margin: Incorporates a hydrate temperature margin into the overall verdict, or reports not_assessed when omitted. - Use Case: An engineer with a 42 km step-out, 95 bara arrival pressure, and 90 bara minimum requirement gets an instant combined screening verdict before launching validated NeqSim hydraulic workflows. ## Quick Start Ask the agent to screen a 42 km tie-back step-out with 95 bara arrival pressure against a 90 bara minimum requirement including a 3 °C hydrate margin.

FAQPage Schema
How do I screen a subsea tie-back step-out distance in Python?▼

Create a StepOutScreeningModel with a maximum step-out guideline and call evaluate with step_out_km, arrival_pressure_bara, and min_arrival_pressure_bara. The result returns step_out_warning, pressure_warning, and an overall_warning of ok, watch, or high.

How to check arrival pressure margin for a subsea tie-back?▼

Pass the estimated arrival pressure and the minimum required arrival pressure to the evaluate method. The margin is the difference in bar; a negative margin is high, a margin below 10 percent of the minimum is watch, otherwise ok.

Does this screening perform hydraulic or thermodynamic calculations?▼

No, it performs no hydraulic, thermal, or thermodynamic calculation. Arrival pressure and hydrate margins must come from validated tools such as NeqSim PipeBeggsAndBrills or flow-assurance workflows; this skill only applies guideline comparisons.

Why is the hydrate warning always not_assessed?▼

The hydrate warning is not_assessed when no hydrate_margin_c value is supplied to evaluate. Provide a hydrate temperature margin from a validated hydrate calculation to receive an ok, watch, or high assessment.

When should I not rely on this step-out screening?▼

Do not use it for design decisions, since thresholds are illustrative public values and a single arrival pressure cannot represent a full route. Any watch or high verdict must be escalated to detailed flow-assurance review with validated NeqSim workflows.
