Thanks Kingnero.

JStephen, Thanks that looks like a good place for me to look.

Thanks Fegenbush, I was thinking more of a padeye or a link plate.

Hi, Sorry, I should have made it clear. I am only considering the plate. A radial load on the pin will try to tear it out of the plate. If the pin is close fitting the plate would have to fail in shear. If the pin is very loose in the hole, then elongation would take place. The round sides of...

Can any one point me to a standard or a study that says bending can be ignored if a pin's diameter is at least 90% of the hole diameter? Thanks in advance.

Thank you all. Your posts have given me considerable food for thought. I have a couple of companies that will be do the job for me, your responses will help me sense check their results. Many Thanks CMcF

???? But then the boom would hit the stack???

Thanks IRStuff, In my head I was thinking that the boom was "touching" the plume so I said conduction, but of course this is convection. CMcF

gerhardl, The requirement is just for a one off job to install bigger lifeboats (average oil worker is a lot fatter now than in 1970's). So I don't think energy recovery will be considered, but your idea for a deflector is worth looking at. Thanks again. CMcF

Thanks gerhardl. That is a good list of criteria. I was also wondering about what effect the exhaust gas itself would have given that it will be mostly steam. CMcF

I need advice on selecting a consultant to advise me on how hot a Crane boom directly over a turbine exhaust stack will get. On oil rigs we have used cranes very close to exhaust stacks but not actually in the plume. My concern is that heat transfer chages from radiation to cunduction. Thanks...

Thanks Steve, we tried that but no use. It may be a network license issue.

My colleague can't see the window that shows the simulation model. We have dual monitors and are pluged in to Autodesk Inventor. Any ideas?

Thanks cottyUK, It was a tacho that I was thinking of.

I have embarresed my self in front of a young electrical engineer. I can not remember the name of the analogue equivalent of an ecoder?

Yes it is. Thanks, I found the product I was looking for after 6 hours on Google.[sadeyes] It is a "Water Driven Proportioning Pump" supplied by Shurflo http://www.shurflo.com/pages/new_industrial/industrial/automotive/doc_sum/94-260-21.html if you are interested. Thanks for your interest. Colin

Hi Latexman, The water is supplied a 3 bar, and mixed 3:1 with anti-freeze. The fittings are 3/8 BSP. The water drives a double piston crank, which drives the anti-freeze pump. It is not an eductor, but like an eductor has no other power supply.

I am reverse engineering a screen wash system (our supplier has gone bust). I need to identify a mixing pump that is powered by the high pressure water supply, that draws in anti-freeze and mixes it with the output? Any ideas?

HEC, a very valid sugestion. However access rather than cost would be an issue. I have since found that EBM PAPST will supply "Encased Fans". These have had their windings and PCB potted, the cable entry sealed and have stainless steel bearings. Thanks any way, Colin

Thanks BrianG, It is a "cold wall" type heatsink. I don't have a salt spray test specification at this time, I am working on a fit for purpose basis.
