Producing hovercraft skirt assemblies

This standard identifies the competences you need to produce hovercraft skirt 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, skirting components, in order to construct complete assemblies or sub-assemblies, such as standard open segments, corner open segment, standard closed segment, cornered closed segment, skirt loop, rear flap, bow corner inner loop and anti spray skirt, bow rope strops and segment to loop assemblies You will be required to lay out and secure the various component parts of the assembly, using the correct methods and techniques in the correct sequence, and to ensure that the skirting components assembled are fit for purpose.

Your responsibilities will require you to comply with organisational policy and procedures for the skirting assembly activities undertaken, and to report any problems with the activities, tools, 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 assembly techniques and procedures. You will know about the methods of assembling the components in adequate depth to provide a sound basis for carrying out the activities, correcting faults and ensuring that the work output is produced to the required specification.

You will understand the safety precautions required when working with skirting 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.

1. work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines

2. follow the relevant instructions, assembly drawings and any other specifications

3. ensure that the specified components are available and that they are in a usable condition

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

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

2. the personal protective clothing and equipment (PPE) to be worn when carrying out the skirting assembly activities

3. safe working practices and procedures for producing skirting assemblies

4. the correct methods of moving, lifting and handling components and assemblies
5. the hazards associated with assembly activities (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 assembly 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. the preparations to be carried out on the components prior to assembling them
10. the various techniques and methods used to assemble components (such as metallic and non metallic fasteners, bonding, welding jigs and fixtures, degreasing and abrading)
11. the use of sealants, adhesives and bonding agents, and the precautions to be taken when using them
12. why it is important to adhere to manufactures instructions when using adhesives, bonding agents and sealants (such as storage, temperature, mixing ratios preparation requirements, curing and cycle times)
13. how to set up and align the various components, and the tools and equipment that are used
14. methods of temporarily holding the assembly or joints together to aid the assembly activities
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
17. the care that is required when using the tools or equipment; the proper way of preserving tools or equipment between operations
18. the problems that can occur when producing assemblies and how these can be avoided 
19. the checking and inspection techniques that can be applied to check that the assembly is to the required specification and within acceptable limits
20. the procedures to be used for the safe disposal of waste materials
21. the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve

   4. ensure that the work area is free from hazards, and that there is sufficient room to complete the assembly activity
   5. correctly prepare and set up the components to be assembled
   6. use the specified or appropriate fixing method
   7. correctly align the components and faces to be assembled
