Inspecting marine coatings
Overview
This standard identifies the competences you need to inspect marine coatings to establish the condition, rectification requirements and compliance with contractual specifications. You will be required to access the appropriate contractual and other specifications and to extract all information necessary to carry out the inspection activities. You will be required to check that all stages of the surface preparation and coating application processes have been completed, in accordance with the process specification. The inspection methods used will include both visual observation and the use of a range of measuring instruments and gauges. You will be expected to select the appropriate inspection equipment to use and to ensure that it is correctly maintained and adjusted. You will be expected to inspect a variety of surfaces and a variety of coatings, in a number of shipyard and onboard environments. You will also be expected to produce a complete and comprehensive report, detailing the condition of the coated marine structure.
Your responsibilities will require you to comply with organisational policy and procedures for the coating inspection activities undertaken and to report any problems with these activities, or the measuring instruments and equipment in use that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work to with a minimum of supervision, taking personal responsibility for your actions and for the quality and accuracy of the work that you carry out.
Your underpinning knowledge will show a good understanding of your work and will provide an informed approach to the inspection of marine coatings. You will know about substrates and their preparation requirements, coating materials and their application requirements, in sufficient depth to provide a sound basis for carrying out the activities, identifying defects, recommending corrective action and for ensuring that the coated surfaces are to the required standards. Compiling accurate and legible reports will be a key issue in completing this standard.
You will understand the safety precautions required when carrying out the inspection 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.

Knowledge and Understanding
You need to know and understand:

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)
the statutory requirements, risk assessment procedures and relevant requirements of HASAWA, COSHH (such as Approved Codes of Practice (ACOP), The Management of Health and Safety at Work Regulations, The Provision and use of Work Equipment Regulations, The Noise at Work Regulations, the Confined Space Regulations)
- the hazards associated with the use of surface preparation equipment and with the application and curing of marine coatings (such as the information in manufacturers' data sheets and in Chemicals Hazard Information and Packaging for Supply (CHIPS) data sheets)
the use of appropriate personal protective equipment (PPE)
the importance of adequate and safe lighting
- the importance of avoiding exposure to hazards while witnessing paint application
- the characteristics of and the applications for, marine coating products (including the use of manufacturers' data sheets, and requirements for the application of particular coating systems in order to comply with contractual specifications)
- the importance of having compatible paint systems including their application such as two pack polyurethane over silicon alkyd
- the characteristics of and the requirement for surface preparation standards
- how to carry out currency/issue checks of the specifications you are working with
- the importance of appropriate environmental conditions for the application and curing of marine coating products
- the importance of using recommended methods of application for particular marine coating systems and of complying with overcoating intervals
- the types of defect to be found in both newly applied and in existing paint systems and their causes
- the importance of complete and comprehensive inspection (including obscured areas and areas of difficult access)
- the requirements for working in confined spaces and the importance of emergency procedures and safe systems of work (including permits to work, Required Air Quantities (RAQs) and local exhaust ventilation (LEV)) to maintain safe conditions; the provision of adequate and safe lighting and avoidance of sources of ignition
- the requirements for working afloat, on outer bottoms and at height
- the types of inspection equipment available and the use of the inspection equipment such as bresle test for salt contamination
- the limitations of your knowledge and of the types of inspection equipment available to you and the need to seek further (such as laboratory) assistance
- the particular importance of ensuring that tank coatings are cured and any solvents released
- basic quality control requirements and the importance of producing comprehensive reports to demonstrate compliance with contractual requirements
- why is it important to keep the inspection equipment clean and free from damage, to practice good housekeeping of tools and equipment and to maintain a clean and tidy working area
- the defects that occur in marine coatings and how they can be identified
- how to carry out the inspection checks of the coatings
- the level of defects that are acceptable in the coatings
- why is it critical that records of inspected coatings are accurate, comprehensive and maintained legibly
- the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
