Description
UNIT DESCRIPTOR:This unit involves the skills and knowledge required to manage the stress and dynamic factors affecting the stability of a small commercial vessel using basic stability criteria. This includes interpreting basic stability criteria, carrying out required stability calculations, correlating and interpreting calculated stability data, managing stability and stress conditions within safety parameters and communicating the stability information t others as required.
Notes
Elements and Performance Criteria
1 Interpret basic stability criteria
  • a Vessel stability data book is located, accessed and interpreted in accordance with established procedures
  • b Stability data for the vessel is interpreted and applied in the management of vessel to ensure it is operated within the safety parameters set by marine regulations
2 Calculate, correlate and interpret basic stability data
  • a Basic stability calculations are accurately carried out in accordance with procedures and regulations
  • b Calculated stability data is correlated with the basic stability criteria set out in the vessel's approved stability book
2 Calculate, correlate and interpret basic stability data(continued)
  • c Vessel's stability is maintained within design operating limits
  • d Unsafe or false information from stability analysis is promptly recognised and recalculated or checked
3 Take action to manage stress and dynamic factors affecting vessel stability
  • a The monitoring of stability and stress conditions of vessel is at a frequency and scope relevant to the nature and speed of vessel's operations and anticipated weather and sea conditions, or in an emergency and is sufficient to enable stress and stability to be maintained within acceptable limits at all times
  • b Appropriate action is taken promptly where stress and stability factors have or could exceed acceptable safety limits and in anticipation of environmental changes that may affect stresses and stability of the vessel
  • c Appropriate precautions are taken where vessel operations may affect the stress and stability conditions of the vessel
  • d Prompt and appropriate action is taken where weight distribution is compromising vessel safety
  • e Action taken in emergency situations is appropriate to the significance of the situation and designed to maintain stresses and stability of vessel within safe limits
  • f Instructions to others are clear, concise, appropriate and timely
4 Maintain records of stability management
  • a Appropriate records are kept of all action taken to monitor and manage the stress and dynamic factors affecting a vessel's stability
  • b Relevant information on vessel stability and action to manage stress and dynamic factors affecting vessel stability are correctly communicated to others as required
