Re: There's that navy humidity reasoning again

"The hull of warships is typically cold because of the outside ocean temperature, he said." There is a substantial layer of insulation on the hull, at least there was when I did trials on them. The interior of the ships is climate controlled, temperature and humidity are closely monitored ...

Re: There's that navy humidity reasoning again

If you were building a house you would have a vapour barrier between the cold hull and the warm inside of the ship to prevent humid air getting through permeable insulating material and the water vapour condensing on the inside of the hull. One way would be to coal Tar epoxy paint and then spray foa...

Re: There's that navy humidity reasoning again

Problems, problems, if they believe inadequate air con is to blame and they want to run the ships longer, why don't they just fix the air con? Mad World, Military procurement. I have just read the article (link below) about the Royal Navy cannibalising spares from one ship to another and how it actu...

Re: 2nd Class Technical Drawing Exam

Remember, the purpose of studying Drawing is so that if a part breaks you can make a drawing of it that a workshop can make.
Include all the information required to make whatever you have to draw.

Re: USS John S. McCain enroute to repair facility

Oh JK! I despair for you. Arm wrestling contractors is no way to get them to give you a highly paid zero hours consultancy contract for life when you retire, you just don't know how to play the game.
(Or maybe you just don't choose to play it)

Re: USS John S. McCain enroute to repair facility

Obviously JK you spent too long at Sea to have learned the art of being a bureaucrat, you bring the Project in on time and under budget and you leverage that to get a more Senior job elsewhere before anyone realises that only half the work originally specified in your project has actually been done,...

Re: MAN User Group

I never understood why the filter before the fuel module was finer than the one after it according to your earlier report, is the new back flushing filter finer than the original?
Thanks for the update, too many people never give feedback after solving the problem.

Re: USS John S. McCain enroute to repair facility

The N. Arch was probably told that if he couldn't insert a 20 foot length into the design within the Budget, there were plenty of others who could!
Maybe that is one of the reasons for the high cost, they will be fitting additional Longitudinals at the same time as the rest of the repairs?
