Dear!
This extract from IMO ” 9.3.7 Except for insulation in refrigerated compartments, insulation material, pipe and vent duct lagging, ceilings, linings and bulkheads should be of non-combustible material. Insulation of pipe fittings for cold service systems and vapour barriers and adhesives used in conjunction with insulation need not be non-combustible but they should be kept to a minimum and their exposed surfaces should have low flame spread characteristics28 . In spaces where penetration of oil products is possible, the surfaces of the insulation should be impervious to oil or oil vapours.”
Now, I already installed insulation (which have DNV cert for Low-flame spread and satisfied IMO requirement for Low-flame spread test) for Engine Cooling Water system (working temp 100 deg C), suddenly QC came and said: why did you install it, it not non-combustible material?
I’m in big trouble now?
1. Is this really need non-combustible material?
2. IF I have to use above insulation (because of schedule and cost if take-out & re-install a new material), how can I ask the Owner for approval?
Thanks for help
