Marine Coastal Pumping Equipment Package

Calculates source-bound coastal pumping equipment metrics from a deterministic SSC-06 task-owned source pack. The template combines tidal pumping head, hydraulic and input power, generator margin, backup runtime, equipment freeboard, corrosion allowance margin, and an overall synthetic pass score.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

easy:
All source-pack values given for the SSC-06 marine coastal pumping package
medium:
All source-pack values given for the SSC-06 marine coastal pumping package

Scenario archetypes

Each generated task is drawn from one of these realistic scenario bands.

Site contexts ground each scenario in a real locale the model can use to infer hidden values.
