Surveying marine pipework systems

This standard identifies the competences you need to make a visual assessment of the condition of marine pipework or pipework system, in accordance with approved procedures. You will be expected to prepare the pipe, ready for the survey and this could include the use of abrasive discs, chemical cleaning, de-burring and polishing tools and pipe cutting equipment. In producing pipe surveys, you would be expected to select and use a range of equipment and techniques, appropriate to the types of material and operations being performed. Survey activities could include using liquid dye penetrant to determine the condition of the pipework and visual inspection, both internally and externally, for cracking, erosion and corrosion.   

Your responsibilities will require you to comply with organisational policy and procedures for the marine pipework surveying activities undertaken and to report any problems with the surveying equipment or materials used, 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 surveying procedures to marine pipework and pipework systems. You will understand the pipework system being surveyed and its application and will know about the surveying activities, equipment to be used and inspections to be carried out, in adequate depth to provide a sound basis for carrying out the activities, recognising defects and ensuring that the survey is completed to the required specification. 

You will understand the safety precautions required when carrying out the pipework surveying activities and with 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, both ashore and on board vessels.

---

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

2. follow and make appropriate use of the specifications for the product or asset being surveyed

3. use all the correct tools and inspection equipment and check that they are in useable condition

4. carry out the surveys in an appropriate sequence using approved methods and procedures
5. identify and assess any defects or variations from the specification and take appropriate action
6. complete relevant documentation and report completion of compliance activities in line with organisational procedures

---

1. the specific safety precautions to be taken when working with pipework surveying equipment on board vessels
2. the importance of ship boundaries and the tag-out system
3. the personal protective equipment (PPE) to be worn whilst carrying out the pipework surveying activities
4. the hazards associated with the pipework surveying activities and how they can be minimised 
5. how to use and extract information from engineering drawings and related specifications (to include symbols and conventions to appropriate BS or ISO standards) in relation to work undertaken

6. the colour code standard used for identifying pipes and why it is important

7. how to interpret first and third angle drawings, imperial and metric systems of measurement 

8. how to carry out currency/issue checks of the specifications you are working with
9. principles and methods of surveying pipework and the type of equipment that is used
10. how to prepare the pipes in readiness for the surveying activities (including visually checking for defects, using abrasive discs, chemical cleaning, de-burring tools, polishing tools, pipe cutting equipment and hand tools)
11. how to evaluate the pipe materials that are surveyed (with regard to pits, cracks and sharp indentations) and how to determine which must be evaluated by further non-destructive testing (NDT) or examination
12. the tools and equipment used in the pipe surveying process and the calibration/care and control procedures
13. how to carry out pipe ovality checks and wall thickness gauging
14. the methods used for surveying pipework systems that are likely to have undergone particular internal corrosion or erosion
15. how to produce survey reports which establish the state of completeness of the pipework systems in the following three categories: pipes in serviceable condition; defective items/pipes; and pipes that require further work or examination
16. the reasons for producing comprehensive, accurate and unambiguous survey reports (integrity of the vessel)
17. the procedure for the safe disposal of waste materials
18. the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
