How to Revise RAeS Level 3 Apprenticeship Assessment Maritime Pipeworker — Royal Aeronautical Society Apprenticeship Assessment Qualification Design and Technology
Core learning outcomes for RAeS Level 3 Apprenticeship Assessment Maritime Pipeworker
Examiner Tips for RAeS Level 3 Apprenticeship Assessment Maritime Pipeworker
- In practical assessments, narrate your actions as you work to demonstrate underpinning knowledge — explain why you chose that jointing method or material.
- When completing written tasks, always reference industry standards (e.g., ISO 9001, classification society rules) to justify your decisions and show professional awareness.
- For assignments, include photographs and detailed logs of your fabrication and testing stages; these serve as strong evidence for competency-based marking.
- Review your risk assessments and method statements meticulously — assessors will check for completeness and practical feasibility, not just a generic template.
- During observations, maintain a tidy and safe work area at all times; good housekeeping is a critical marking criterion under 'professional behaviours'.
Common Mistakes in RAeS Level 3 Apprenticeship Assessment Maritime Pipeworker
- Misreading isometric drawings, leading to incorrect pipe routing or failure to allow for expansion loops and supports.
- Using incorrect filler metal or flux when brazing copper-nickel pipes, causing weak or contaminated joints.
- Omitting essential non-destructive testing (e.g., dye penetrant or radiography) before system pressurisation, resulting in undetected leaks.
- Neglecting to purge pipes with inert gas when welding stainless steel, causing oxidation and weld defects.
- Failing to account for galvanic corrosion when joining dissimilar metals without insulating gaskets or coatings.
- Ignoring the need for stress relief or cold springing in high-pressure steam or fuel lines, leading to premature fatigue failure.
Key Marking Points
- Award credit for accurate interpretation of isometric and P&ID drawings, identifying symbols, dimensions, and material specifications.
- Demonstrate correct selection and preparation of pipe materials, including cutting, bevelling, and cleaning in accordance with WPS and technical instructions.
- Credit must be given for proper execution of at least two different jointing techniques (e.g., MMA/TIG welding, brazed joints, or mechanical couplings) with joints meeting visual inspection criteria (no cracks, correct alignment, and minimal distortion).
