2 | Identify commercial vessel types and their structure | 2.1 | Basic factors determining design of commercial vessels are outlined |
2.2 | Features of vessel designed to ensure its watertight and weather tight integrity are identified and maintained | ||
2.3 | Survey or inspection plan relating to vessel design is identified and implemented | ||
2.4 | Vessel construction methods and materials are identified and used as the basis to determine inspection and survey tasks | ||
3 | Interpret basic vessel stability criteria | 3.1 | Basic stability theory as outlined in the National Standard for Commercial Vessels (NSCV) in relation to construction of a commercial vessel is accurately defined and basic stability calculations are performed |
3.2 | Purpose of a vessel stability assessment is correctly explained | ||
3.3 | Documentation and records required by surveyor to assess stability of vessel are identified and confirmed according to NSCV | ||
4 | Apply vessel construction theory to survey | 4.1 | Different types of vessel materials are identified to determine scope of survey |
4.2 | Survey plan appropriate to type of vessel is developed according to survey requirements and discussed with surveyor | ||
4.3 | Feedback on survey plan is sought from others and possible changes or improvements are clarified where required and incorporated |
Required Skills

Evidence Required
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: providing accurate and reliable information developing effective planning documents attention to detail when completing documentation performing accurate and reliable calculations. |
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 applying vessel construction theory to marine survey tasks 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 applying vessel construction theory to marine survey tasks 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. |
