Abstract
In navigation practice, before sailing, all parameters related to the ship’s stability are calculated in advance through a loading instrument approved by the society classification and these parameters meet the requirements of International Code on Intact Stability (IS Code-2008). However, when the ship sails at sea, regular and constant checking of the ship’s stability is difficult because the loading instrument does not have the feature of calculating the ship’s stability in real time. Establishing the program on performance of the stability information in real time for bulk carriers will help the deck officers can assess the ship’s stability from time to time and timely take appropriate actions when the ship tends to reduce stability or destabilize.
