Active (Real Time)   system receives real time tanks levels, tank weights, tank volumes,
drafts, mooring tensions, tow line tensions, line paid out etc
     
Passive (Predictive)   manual loading data entry only
     
TYPES   Ocean Motions provides all 3 types:
     
Type 1   Software calculating intact stability only
     
Type 2   Software calculating intact stability and checking damage on the basis of
KG Max or GM Min limit curves
     
Type 3   Software calculating both intact and damage stability by direct
application of pre-programmed damage cases (HSE IMO MODU
MARPOL…)

otherwise known as:
