External evidence register
Each page below shows exactly what was taken from the external source, what OffshoreLH2 calculated, the predeclared acceptance rule, the resulting error, and what the comparison can—and cannot—support.
Seven quasi-steady homogeneous-reference slopes and six full pressure-time homogeneous curves. The measured stratified curves are also digitized and kept as model-form evidence.
Best full-curve NRMSE: 0.32% · worst: 4.58%.
Normal-hydrogen saturation pressure, densities and enthalpy checks at 20 K against the Leachman reference formulation/table.
Evidence type: property/reference verification.
Ammonia synthesis mass balance and makeup compression at the published operating point.
Errors: −2.0% and +2.2%.
Hydrogen-fuelled ship technical distance limit using the published vessel volume, pressure range, speed, propulsion power and fuel-cell efficiency.
Error: +4.7% versus a 10% tolerance.
Adiabatic loading to 300 bar. The final mass comparison is preserved as a failure rather than retuned.
Error: −7.6% versus a 5% tolerance.
How to read these pages. PASS applies only to the quantity and boundary stated on the individual page. A literature model comparison is not the same as measured experimental validation, and descriptive comparisons are not silently promoted to passes.
