Shaping marine steelwork using a power press

This standard identifies the competences you need for bending and forming marine steelwork (of 3mm and above) for marine fabrications, using power operated equipment such as press brakes, bending machines and power presses, in accordance with approved procedures. You will be required to operate the appropriate bending and forming equipment, in accordance with the instructions for the operations being performed. You will need to check that all the required safety devices are operating correctly and that the machine guards are in place and correctly adjusted.

Items to be bent and formed may include ferrous and non-ferrous materials and tasks will include producing bends of various angles, setting plate ends for rolling operations and producing curved sections.

Your responsibilities will require you to comply with organisational policy and procedures for the activities undertaken and to report any problems with the equipment, materials, tooling or bending activities that you cannot personally resolve, or are outside you personal authority, to the relevant people. You will be expected to work to instructions, 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 be sufficient to provide a sound basis for your work and will provide an informed approach to applying the power pressing procedures required. You will have an understanding of the bending processes and will know about the equipment and its application, in adequate depth to provide a sound basis for carrying out the activities and for ensuring that the completed work is to the required specification.

You will understand the safety precautions required when working with power operated presses and the safeguards necessary for undertaking the activities safely and correctly. You will be required to demonstrate safe working practices and procedures throughout and will understand the responsibilities 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. confirm that the equipment is set up correctly and is ready for use
3. operate the machine controls safely and correctly in line with operational procedures
4. produce shaped components to the required specification
5. carry out quality sampling checks at suitable intervals
6. deal promptly and effectively with problems within your control and report those that cannot be solved
7. shut down the equipment to a safe condition on conclusion of the machining activities

1. the specific safety precautions to be taken when working with power-operated bending and forming equipment (such as press brakes and/or bending machines) in a marine fabrication environment, both on land and onboard vessels (including general workshop and site safety and accident procedures)
2. the statutory requirements, risk assessment procedures and relevant requirements of HASAWA, COSHH and Work Equipment Regulations that apply to the work carried out or equipment being used
3. the correct personal protective equipment (PPE) and handling precautions to be taken, when working with heavy platework
4. the correct methods of moving or lifting sheet or plate materials
5. the hazards associated with power operated bending and forming processes (such as handling heavy sheet plate materials and components; operating moving equipment; using faulty or badly maintained tools and equipment) and how they can be minimised
6. the safe working practices and procedures required for operating power presses and bending machines
7. how to obtain and interpret information from job instructions, drawings and bending specifications, in relation to the work undertaken
8. marking out conventions applicable to the bending process (including centre lines and bending lines)
9. the various types of power-operated bending machines that are used, and their typical applications
10. the methods and techniques that are used to obtain the required shape and size
11. ways of limiting distortion, marking and creases in the finished workpiece
12. the preparations to be carried out on the materials, prior to bending them
13. the basic characteristics of the materials with regard to the bending operations undertaken
14. the need to take care of the bending tools and equipment and how to recognise faulty or damaged forming tools
15. how bending and forming tools should be stored
16. why tool/equipment control is critical and what to do if a tool or piece of equipment is unaccounted for on completion of the activities
17. the problems that can occur with the bending and forming activities and how they can be avoided
18. the organisational quality control procedures that are used and how to recognise defects in the bends that you produce
19. how to make dimensional and forming inspection checks and the tools and equipment that can be used
20. the procedure for the safe disposal of waste materials
21. the extent of your own authority and whom you should report to if you have problems that you cannot resolve

   3. the press is in a safe and serviceable condition
   4. press settings are suitable for the material thickness and operation to be performed
   5. equipment for supporting the plate at the start of the pressing operations is in place

2. Use one of the following types of power operated bending equipment:

   1. press brakes
   2. powered bending machine
   3. power press
   4. variable power press

3. Perform operations that produce three of the following:

   1. bends at 90°
   2. bends of various angles, knuckles, cambers or strakes
   3. set plate ends for rolling
   4. box, square and rectangular sections, bulkheads
   5. swaging bulkheads, walls or partitions
   6. multi-bend platework, bulkheads or walls
   7. curved plates, bollards, hawse pipes

4. Bend and form marine steelwork of 3mm or greater thickness, for one of the following:

   1. carbon steel
