3.4 Simulation of Container LoadingLJnloading
The Container loadinglunloading simulation is included in stability assessment of ship, assessment of
process, and assessment for optimal position of cranes during container loadinglunloading.
Figure 7 shows the procedures of simulation for container loadinglunloading
The following items were considered in the development of container loading/unloading .
- The container loadinglunloading simulation use hull form, compartment, port, and facilities model
and CAE programs.
- The constraints such as sequence of loadinglunloading and a moving distance of cranes, are permitted
within limits of values defined in [environment] menu.
- When crane picked container up off the deck, stability assessment program is executed.
- When stability of ship disappeared during simulation, system is terminated with beep sound.
