6.2.1 Repair process:
-
.1 tank cleaning, ventilation/gas-freeing and
mucking-out;
-
.2 de-scaling;
-
.3 degreasing and oil film removal;
-
.4 fresh water rinsing;
-
.5 drying; and
-
.6 surface preparation (surface preparation method
chosen depends on the amount of failure and the service life intended
– see relevant tables 3.1 to 3.3 below).
6.2.2 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.
6.2.3 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.
