Description
UNIT DESCRIPTOR:This unit involves the skills and knowledge required of a Watchkeeper (Deck) and Master (Less than 500 GT) to determine the stability and trim of a commercial vessel, to ensure that stability conditions of the vessel comply with the intact stability criteria of the International Maritime Organisation under all conditions of loading.
Notes
Elements and Performance Criteria
1 Determine the vessel's stress and stability for all stages of the voyage
  • a Stability calculations and weight distribution planning is conducted at a time, frequency and scope appropriate to the proposed nature of the voyage or operation
  • b Weight distribution is designed to maintain the vessel within acceptable stability and stress limits for all stages of the voyage
  • c Trim, draughts and list are adjusted as required to safely and efficiently progress all vessel operations
  • d Stability and stress monitoring is conducted in time and scope relevant to the nature and speed of vessel operations, and sufficient enough to ensure that stress and stability remain within acceptable limits at all times
  • e Action taken where weight distribution is compromising vessel safety, is prompt and designed to maximise safety
  • f Tests and checks using computer-based stability programs or other appropriate methods are conducted at a frequency and scope that conform to manufacturer's instructions
1 Determine the vessel's stress and stability for all stages of the voyage(continued)
  • g Spurious or incorrect information from stress and stability calculations is promptly recognised and recalculated
2 Maintainrecords ofstress and stability calculations
  • a Records of stress and stability calculations and action to maintain trim, stability and stress levels are maintained in accordance with company procedures and regulatory requirements
