	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 __________________ cvt_82

	We can't help. It shall be as per contract agreements. If agreement says "non combustible" then you should provide it. If "non combustible" is really not required, request for amendments in contractual terms giving reasonable reasons. Other way round is to prove the installed material as "non combustible" by testing its sample by any approved lab/body.

	GA Sounds like you may be in trouble... You agreed to a contract before beginning the project (I'm assuming) and that agreement MUST be met exactly as written. If you see any potential issues with the project from the start, this is when you can ask for an amendment or clarification if anything (like this) raises any questions. On a personal note, I have been working on a job which will be shipped nearly on the opposite side of the planet. The salesman/project managers received the specifications, provided a quote, and everything was agreed upon. Now after the project has begun (fully designed, materials on the way), the question has been raised... "Gee, I wonder if they meant US or Imperial Gallons?" 1.2009 US gallons = 1 Imperial Gallon... so when you take that to any magnitude, you could be in real trouble... fortunately for us, I gave just enough wiggle room to still be ok, and our order of magnitude was rather small. Also, the type of gallon was not specified by our customer, and we simply made the assumption... we were both in the wrong, but (at least this time) no harm no foul this time around. __________________ Don't believe everything you read on the Internet!
