URN: SEMME3217
Business Sectors (Suites): Marine Engineering Suite 3
Developed by: Enginuity
Approved on: 31 Mar 2019

Overview

This standard identifies the competences you need to repair composite components fitted to yachts or boats, in accordance with approved procedures. You will be required to use appropriate drawings, specifications and repair documentation and to extract the relevant information in order to carry out the necessary repairs to the components or assemblies.

You will be expected to identify the method of repair to be used and to select suitable repair materials. You will repair a range of composite components such as craft/vessel structural components and ancillary components such as panels and covers. The components repaired will require the use of a range of resin and fibre materials and appropriate repair techniques.

Your responsibilities will require you to comply with organisational policy and procedures for the repair activities undertaken and to report any problems with the activities, equipment or materials that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out. **

Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to applying composite component repair procedures on yachts or boats. You will understand the repair techniques used and their application, in adequate depth to provide a sound basis for carrying out the activities to the required specification. 

You will understand the safety precautions required when carrying out the repair activities and when using the associated tools and equipment. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and others in the workplace.


Performance criteria

You must be able to:

  1. work safely at all times, complying with health and safety legislation, regulations, directives and other relevant guidelines
  2. follow the relevant specifications for the component to be repaired
  3. prepare the component for repair
  4. carry out the repairs within agreed timescale using approved materials and components and methods and procedures
  5. ensure that the repaired component meets the specified operating conditions
  6. complete relevant documentation in line with
    organisational procedu
    res, of all repair work carried out

Knowledge and Understanding

You need to know and understand:

  1. health and safety precautions to be taken and procedures to be used when working with composite materials, consumables, tools and equipment in the specific work area
  2. how to recognise and deal with emergencies and the procedures to be followed (such as methods of safely evacuating and closing down of compartments in the case of fire or other major incident, first aid, fire fighting and resuscitation of personnel)
  3. the hazards associated with using composite materials, consumables, tools and equipment and how to minimise these in the work area
  4. the protective equipment (PPE) that is needed for personal protection and where required, the protection of others

  5. the application of COSHH regulations in relation to the storage, use and disposal of composite materials and consumables

  6. the specific workshop environmental conditions the must be observed when repairing yacht or boat composite components (such as temperature, humidity, styrene levels to threshold limits, fume/dust extraction systems and equipment)
  7. how to use and extract information from repair drawings and related specifications (to include symbols and conventions to appropriate BS or ISO standards) in relation to work undertaken
  8. how to interpret first and third angle drawings, imperial and metric systems of measurement, workpiece reference points and system of tolerancing
  9. conventions and terminology used when repairing composite mouldings (such as disbonds, de-lamination, resin injection, resin voids, core potting, repair patches)
  10. the different forms of damage or defect that can occur in the composite components and how this affects the type of repair selected
  11. how to asses the damage or defect in the composite components and how to determine the most suitable type of repair
  12. the importance of ensuring that the repair conforms to the repair specification
  13. failure modes for various composite mouldings and what can contribute to these
  14. different types of composite resin systems, fibres and reinforcements and the types of defect that might be present
  15. different bonding agents, methods used and the sorts of defect that might be present in the bond
  16. the various methods that can be used to help identify whether defects are present in the mouldings (to include visual inspection, touch, sound, measurement, mechanical and non-destructive tests)
  17. correct methods of storage and handling of composite materials 
  18. tools and equipment used for various activities associated with composite mouldings
  19. the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
