6.2 Principles of repairs

  6.2.1 Repair process:

  • .1 mud out (“slurry up” and pump out all mud);

  • .2 de-scaling (hand scrape off loose scale − the use of magnesium descaling can be considered);

  • .3 fresh water rinsing;

  • .4 drying;

  • .5 surface preparation (surface preparation method chosen depends on the amount of failure and the service life intended);

  • .6 anode protection (protection of items should not be coated); and

  • .7 coating.

  6.2.2 It is recommended that the process, specification, coating application parameters, standards and time schedule are discussed and agreed upon by the parties involved and presented to the Administration for review. The Administration may, if it so requires, participate in the agreement process.

  6.2.3 It is essential that, if a contractor is providing the service, he can prove that all personnel are fully qualified to carry out the required work. It is also necessary that, whilst on board, the team is fully conversant with appropriate ship operation, safety and evacuation requirements.

  6.2.4 It should be realized that more control over the coating process can be achieved in dock and, hence, the overall cost effectiveness of repair must establish whether the required service life will be achievable.
