Producing patterns for rigid inflatable boat (RIB) sponsons
Overview
This standard identifies the competences you need for producing pattern developments and marking out of templates for rigid inflatable boat (RIB) sponsons, prior to cutting materials, in accordance with approved procedures. You will be required to select the appropriate materials and equipment to use, based on the information presented to you and the accuracy to be achieved. Patterns to be marked out and developed could include baffle sections, stripes, fair leads, reinforcing and wear patches
Your responsibilities will require you to comply with organisational policy and procedures for the marking out and pattern development activities undertaken, and to report any problems with the equipment, materials or pattern development activities 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 pattern development activities. You will understand the marking out and pattern development process, and its application, and will know about the equipment, materials and processes to be carried out, in sufficient depth to provide a sound basis for carrying out the activities, correcting faults and producing the patterns and templates to the required specification.
You will understand the safety precautions required when carrying out the pattern development 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:
- work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- obtain and use the correct information for marking out
- obtain the appropriate marking out equipment and check that it is in a usable condition
- prepare suitable datum's and marking out surfaces
- mark out using specified and approved methods
- check that the marking out complies with the specification
- produce patterns to the required specification
- deal promptly and effectively with problems within your control and report those that cannot be resolved
- complete relevant documentation in line with
organisational procedures
Knowledge and Understanding
You need to know and understand:
- the specific safety precautions to be taken when working in a marine manufacturing environment such as general workshop and site safety, appropriate personal protective equipment, accident procedure; statutory regulations, risk assessment procedures and relevant requirements of HASAWA, COSHH and Work Equipment Regulations)
- the personal protective clothing and equipment (PPE) to be worn when carrying out the pattern development activities
- the correct methods of moving or lifting materials
- the hazards associated with manufacturing activities (such as handling materials/components; using dangerous or badly maintained tools and equipment) and how they can be minimised
- how to obtain the necessary drawings, template specifications and job instructions
- how to extract information from drawings and related specifications (to include symbols and conventions to appropriate BS or ISO standards) in relation to work undertaken
- how to carry out currency/issue checks of the specifications you are working with
- principles and techniques for marking out and producing pattern developments
- use of marking out conventions, datum edges/lines and centre lines
- the preparations to be carried out on the material prior to marking out, to enhance accuracy and safety
- the effective use and care of tools and equipment used in the marking out and manufacture of patterns
- how to mark out and preserve the template for maximum clarity, accuracy and ease of transfer
- ways of laying out the shapes/patterns to maximise the use of materials
- the importance of checking the marked-out shape for dimensional accuracy before cutting the material
- the importance of using tools only for the purpose intended; the care that is required when using the equipment and tools; the proper way of preserving and storing tools and equipment between operations
- the importance of clearly identifying the material part number and the manufacturing details on the marked out material or template
- the problems that can occur in marking out pattern developments and how these can be avoided
- the procedures to be used for the safe disposal of waste materials
- the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
Scope/range
Scope Performance
1. Carry out all of the following during the manufacture of the pattern:
- obtain and use appropriate, drawings, instructions, sketches or specifications
- adhere to relevant COSHH requirements, risk assessments and other relevant safety standards
- check that all tools and equipment used during the manufacture are in a safe, tested and usable condition
- ensure that the work area is free from hazards, and that there is sufficient room to complete the manufacturing activity
- return all tools and equipment to the correct location on completion of the activities
- leave the work area in a safe condition and to the prescribed category of cleanliness
2. Mark out shapes to be developed, using two types of pattern material from the following:
