List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
ELEMENTS | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1 | Manage vessel trim under normal operating conditions | 1.1 | Stability analysis and weight distribution planning are conducted at a time frequency and scope appropriate to the proposed nature of the voyage and vessel operation |
1.2 | Weight distribution is arranged to maintain vessel within acceptable stability limits for the anticipated operational situations likely to be experienced during the voyage |
1.3 | Calculations are made to determine the draught and centre of gravity of vessel after adding, removing or shifting weight |
1.4 | Factors affecting the stability and trim of vessel are identified and allowances are made in calculations |
1.5 | Trim, draughts and list of vessel are controlled as required to ensure they are suitable to progress all anticipated vessel operations |
2 | Control vessel stability when compartment is flooded | 2.1 | Damage to vessel and nature of floodingof compartments is assessed |
2.2 | Effect upon vessel stability of flooded and flooding compartments is evaluated |
2.3 | Suitable strategyfor maintaining or restoring trim and stability is devised |
2.4 | Where stress limits of the vessel are exceeded as a consequence of damage and/or flooding, appropriate action is initiated to ensure safety of personnel, including abandoning the vessel as required |
3 | Manage stress conditions of the vessel | 3.1 | Stress levels of the vessel are assessed according to manufacturer specifications |
3.2 | Stability of the vessel is monitored at a frequency and scope relevant to vessel operations, sufficient to enable stress and stability to be maintained within acceptable limits at all times |
3.3 | Appropriate action is taken where weight distribution has or could exceed acceptable safety limits |
4 | Maintain records of stability management | 4.1 | Data and information related to stability management is accurately recorded |
4.2 | Data and information related to stability management is filed and stored according to organisational procedures |
Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions on at least one occasion and include: |
applying International Maritime Organization (IMO) recommendations concerning vessel stability applying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements and work practices attending to appropriate level of detail in recordkeeping determining stability and trim requirements for docking or slipping the vessel determining the effect on trim and stability of vessel in the event of damage to and consequent flooding of a compartment, and countermeasures to be taken interpreting and applying information on the fundamental principles of vessel construction and the theories and factors affecting trim and stability, and measures necessary to preserve trim and stability maintaining stability and stress conditions within safe limits at all times producing accurate and reliable documentation using automatic data-based equipment. |
Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions and include knowledge of: |
causes and repercussions of a heeling vessel effects of angle of loll including centre of buoyancy, how a ship behaves at the angle of loll, inherent dangers, corrective action and the difference between a loll and a list effects of density of sea water on the draught and freeboard of a vessel features of the load-line and draught marks of a vessel and procedures for carrying out related calculations fundamental principles of ship construction and the theories and factors that impact on trim and stability, and measures necessary to preserve trim and stability IMO recommendations concerning vessel stability levelling arrangements for damaged side compartments principle stresses that act on the structure of a vessel, including panting and pounding principles of parametric rolling and control methods principles of synchronous rolling and methods for its control procedures for calculating the required load distribution to achieve the desired trim typical problems related to the control of trim and stability for vessels of 500 gross tonnage and more WHS/OHS requirements and work practices. |
As a minimum, assessors must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations, current at the time of assessment.
As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations, current at the time of assessment.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Assessment must occur in workplace operational situations or where this is not available, in an industry-approved marine operations site or simulation where managing stability of a vessel of 500 gross tonnage or more may be demonstrated.
Resources for assessment include access to:
relevant documentation including workplace procedures, regulations, codes of practice and operation manuals
tools, equipment, materials and personal protective equipment currently used in industry.
Performance should be demonstrated consistently over time and in a suitable range of contexts.
