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

Overview

This standard identifies the competences you need to produce marine sheet metal outfitting assemblies, in accordance with approved procedures. You will be required to interpret specifications and drawings correctly, to bring together, assemble and join, in the right order, sheet metal components and/or light sections, in order to construct complete marine outfitting assemblies or sub-assemblies, such as tanks, ducting and trunking, guards, hoods, stowage racks, shower and toilet cubicles, galley equipment, kit lockers, pyrotechnic lockers, protective covers and cladding. You will be required to lay out and secure the various component parts of the assembly, using mechanical fastenings, resistance welding or self-securing methods, in the correct order and to ensure that the components are assembled in a manner that is fit for purpose.

Your responsibilities will require you to comply with organisational policy and procedures for the marine sheet metal outfitting assembly activities undertaken and to report any problems with the activities, tools, equipment or materials that you cannot personally resolve, or that 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 marine sheet metal outfitting assembly techniques and fixing procedures. You will understand the assembly techniques used and their application. You will know about the methods of assembling the components of the required strength and that are fit for purpose, in adequate depth to provide a sound basis for carrying out the activities, correcting faults and for ensuring that the work output is produced to the required specification.

You will understand the safety precautions required when working with sheet metal components and their 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.

  4. use the appropriate methods and techniques to assemble the components in their correct positions
  5. secure the components using the specified connectors and securing devices
  6. check the completed assembly to ensure that all operations have been completed and the finished assembly meets the required specification
  7. deal promptly and effectively with problems within your control and report those that cannot be solved
  8. complete relevant documentation in line with organisational procedures

Knowledge and Understanding

You need to know and understand:

  1. the specific safety precautions to be taken when working in a marine fabrication environment and when producing sheet metal outfitting assemblies (including general workshop and site safety, appropriate personal protective equipment (PPE), accident procedure; statutory regulations, risk assessment procedures and COSHH regulations, safe disposal of waste materials)

  3. safe working practices and procedures for producing marine sheet metal outfitting assemblies
  4. the correct methods of moving or lifting bulky sheet metal fabrications
  5. the hazards associated with marine sheet metal outfitting assembly work (such as using dangerous or badly maintained tools and equipment, lifting and handling long and heavy components, cuts, slips trips and falls) and how they can be minimised
  6. how to obtain the necessary drawings and joining specifications
  7. how to extract information from engineering drawings and related specifications (to include symbols and conventions to appropriate BS or ISO standards), in relation to work undertaken
  8. how to carry out currency/issue checks of the specifications you are working with
  9. how to interpret first and third angle drawings, imperial and metric systems of measurement, workpiece reference points and system of tolerancing
  10. how to interpret marking out conventions (such as cutting lines, centre lines, hole positions)
  11. the preparations to be carried out on the components prior to assembling them
  12. the various methods of securing the assembled components (such as threaded fasteners, screws, special fasteners, resistance and tack welding methods and techniques, adhesive bonding of components, and self-secured joints - such as knocked up, paned down, swaged and joggled)
  13. how to set up and align the various components and the tools and equipment that are used
  14. methods of temporarily holding the joints together to aid the assembly activities (such as clamps, rivet clamps)
  15. the use and care of tools and equipment and the control procedures
  16. the importance of using tools or equipment only for the purpose intended; the care that is required when using the tools or equipment; the proper way of preserving tools or equipment between operations
  17. the problems that can occur when producing sheet metal assemblies and how these can be avoided
  18. inspection techniques that can be applied to check that shape (including straightness) and dimensional accuracy are to specification and within acceptable limits
  19. the extent of your own responsibility and to whom you should report if you have problems that you cannot resolve
