Vertical Can Pump Installation

Dear all,
I am newly graduated Mechanical Engineer. I would like to ask for your experience.
We are going to install Vertical Can Pump on offshore gas processing plattform. The pump weighed 2100 lb and it is 17 ft long. We have to drill 12 inch hole to install it on Cellar Deck. The pump will be put through the hole and will be mounted on deck plate(5/8&quot with four 1" bolts.
I am worried about vibration & Civil problem. So I have some questions.
Do you think this pump need and extra support (pump seat, can support)?
What is the most important thing that I have to concern on this type of pump installation?

I have not experience in such pumps but if vibration is a concern to include the ordinary vibration isolators (or some application akin to them) plus vibration cutoffs in the piping systems should be possible to implement without excessive cost, specially at installation time.

I only once have met complaints of a condominium community pumps noise. Was only 4 flats per building and the complaining party lived just exactly over the room holding equipment that served more than 4, there's a psychological component to this. We did some corrections and public complaints ended.

First of all you should consult the installation notice of the pump manufacturer.
Then you should check if the support has sufficient resistance for pump mass: as you seem wanting to install it on a deck plate, this is not necessarily true. Normally one would expect that at least two beams are provided sideways of pump and that the mounting bolts are secured into the flanges of such beams.
Of course also vibration is an issue: this is primarily influenced by support stiffness, but depends also on pump geometry and position of nozzles. Once again the pump manufacturer should be able to give an advice on this.

Find out where one of these pumps is already operating and visit the site. I believe you will find that vibration is a smaller problem than initially envisioned. This will also give you an idea of how the pump is held down. Good luck.

 

For this offshore application your greatest loading will be due to wave motion against the pump column. This will apply fluctuating bending moments on the support plate. I feet that you should probably fabricate a support stool, tied back to support beams and mount the pump directly to the stool without isolation dampeners.
