The following tabular data that specifies system and compartment levels was read from the GUI:
|ID||S1/C1 level||S2/C2 level||S3/C4 level||S4/C4 level|
|SYSTEMS||>=90||>=80||>=70||all other cases|
|COMPARTMENTS||>=90||>=80||>=70||all other cases|
S-level is deduced by comparing the operational critical systems percentage to these values.
C-level is deduced by comparing the share of compartment volume not damaged to these values.
Functionality of Systems
Critical systems are included in this scenario.
Operational Readiness Level Definitions
Operational Readiness Level has five categories that describe reduced operability of a vessel. It takes into account the floating position and the proportion of undamaged compartment volume and critical systems.
The S-level is ignored if the vessel doesn't contain critical systems.
ORL level is deduced as the minimum from C/F/S levels:
- ORL1: All of the levels C/F/S are 1.
- ORL2: The worst value from C/F/S levels is 2.
- ORL3: The worst value from C/F/S levels is 3.
- ORL4: The worst value from C/F/S levels is 4.
- SUNK: Ship is sunk.
Floating Position Level Definitions
The following tabular data that specifies F-levels was read from the GUI:
|Criteria||Explanation||Quantity||F1 level||F2 level||F3 level||F4 level|
|HEEL||[degrees]||<5||<7||<12||all other cases|
|TRIM||[m]||<0.5||<1||<1.25||all other cases|
The following texts are associated to each level:
- F1: No stability issues
- F2: Minor stability degradation
- F3: Severe stability degradation
- F4: Stability compromised
- SUNK: Sunk. (This level is applied if ship is sunk.)
