Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below.
Basic data may include:
Certificate of survey
Vessel log
Vessel plans and drawings
Vessel stability data book
Commercial vessels must include:
Vessels defined as commercial vessels in Marine Safety (Domestic Commercial Vessel) National Law
Precautions may include:
Ballast management
Closing openings exposed to weather
Damage control measures to maintain, stabilise or restore watertight integrity of hull during an emergency
Managing distribution of load on vessel
Managing position, stowage and lashing of cargo, stores and equipment, and location of passengers
Taking precautions when using lifting equipment and associated gear
Emergency situations may include:
Flooding when there is damage to hull
Inadequate securing of weights on board

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, the required skills and knowledge, the range statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the Elements, Performance Criteria, Required Skills, Required Knowledge and include:
analysing, planning and carrying out vessel stability calculation for at least five different types and size of vessels
performing accurate and reliable calculations
attention to appropriate level of detail in recordkeeping
providing high quality reports.
Context of and specific resources for assessment
Performance is demonstrated consistently over time and in a suitable range of contexts.
Resources for assessment include access to:
industry-approved marine operations site where evaluating vessel stability using available information can be conducted
tools, equipment and personal protective equipment currently used in industry
relevant regulatory and equipment documentation that impacts on work activities
range of relevant exercises, case studies and/or other simulated practical and knowledge assessments
appropriate range of relevant operational situations in the workplace.
In both real and simulated environments, access is required to:
relevant and appropriate materials and equipment
applicable documentation including workplace procedures, regulations, codes of practice and operation manuals.
Method of assessment
Practical assessment must occur in an:
appropriately simulated workplace environment and/or
appropriate range of situations in the workplace.
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate to this unit:
direct observation of the candidate evaluating vessel stability using available information
direct observation of the candidate applying relevant WHS/OHS requirements and work practices.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.
In all cases where practical assessment is used it should be combined with targeted questioning to assess Required Knowledge.
Assessment processes and techniques must be appropriate to the language and literacy requirements of the work being performed and the capacity of the candidate.
