Application
This unit involves the skills and knowledge required to recognise how the construction and structural issues of commercial vessels relate to marine survey tasks.
This unit applies to people who assist marine surveyors or undertake administration duties in the maritime industry and/or marine surveying sector.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. | ||
1 | Identify major parts of a hull relevant to commercial vessel inspections and surveys | 1.1 | Appropriate nomenclature is used to identify major parts of hull to be inspected as part of commercial vessel marine survey |
1.2 | Structure of vessel hull in plan-view, profile, cross-section and perspective are accurately analysed across a range of different plans and drawings of vessels to determine survey requirements | ||
1.3 | Use of plans and drawings in the survey are identified and applied during survey plan development | ||
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 the 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 |

Assessment Conditions
Assessors must satisfy National Vocational Education and Training Regulator (NVR)/Australian Quality Training Framework (AQTF) assessor requirements.
Assessment must satisfy the National Vocational Education and Training Regulator (NVR)/Australian Quality Training Framework (AQTF) standards.
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 these are not available, in simulated workplace operational situations or an industry-approved marine operations site that replicates workplace conditions.
Resources for assessment include access to:
relevant regulatory and equipment documentation including workplace procedures, regulations, codes of practice and operation manuals that impacts on work activities
tools, equipment, material and personal protective equipment currently used in industry.
Performance should be demonstrated consistently over time and in a suitable range of contexts.
