Tankerman · Operations — Loading Plan / Stress and Stability
A cargo loading/discharge plan for a tank vessel is prepared in advance primarily to:
- AKeep hull stresses (shear/bending), stability, trim, and tank limits within allowable values throughout the operation✓ Correct
- BDecide the crew's meal schedule
- CMaximize the time alongside
- DAvoid using the cargo computer
Explanation
The plan sequences tanks and rates so that at every stage the still-water bending moment and shear force, the stability (GM, free surface), and the trim/list stay within limits, and no tank is overfilled. A loading computer is used to verify the plan and monitor the operation.
