S = s_\text{crew} + s_\text{hull} + s_\text{mach} + s_\text{mgmt} + s_\text{env}

Symbol	Meaning	Unit
$s_\text{crew}$	Crew training, certification, retention	0–100
$s_\text{hull}$	Hull and structure (age, coating, surveys)	0–100
$s_\text{mach}$	Machinery reliability and redundancy	0–100
$s_\text{mgmt}$	Management (ISM, SIRE, audit history)	0–100
$s_\text{env}$	Environment (NOx, SOx, CO₂, waste)	0–100
