Displacement

1. Ship stability data book is accessed and checked for endorsement

2. Sample worked data is interpreted to determine ship safety parameters

3. Transverse and longitudinal stability is accurately calculated using data extracted from the body of ship stability data book

4. Stability calculations are checked to ensure they correlate with data set out in ship stability book

5. Spurious or incorrect information is recognised and recalculated

6. Trim, draughts and list are adjusted, as required

7. Stability calculations are conducted at a time, frequency and scope appropriate to voyage

8. Stability calculations are used to plan weight distribution to ensure assigned load line conditions are not exceeded

9. Weight distribution is controlled to maintain ship within acceptable stability and stress limits for loading operation and at all stages of voyage

10. Appropriate action is taken when weight distribution is compromising ship safety

11. Data and information related to stability management is accurately recorded

12. Data and information related to stability management is filed and stored according to organisational procedures
