field engineering for piping erection at petrochemical plants.!!

(OP)
hi can anybody suggest what should be the best approach for fast erection of piping at plants with greater piping scope. what should be the fabrication techniques, weld mapping, support erection and piping around the equipment?? thanks

RE: field engineering for piping erection at petrochemical plants.!!

1. Hire an erection contractor with experience in piping and support installations.
2. Hire an erection contractor with experience in piping and support installations.
3. Hire an erection contractor with experience in piping and support installations.

Need I say more?

RE: field engineering for piping erection at petrochemical plants.!!

The key to construction of major or large types of piping scope is to have a complete construction package consisting of (but not limited to):

General arrangement plans and elevations
Piping isometrics for all lines 2" and above
Pipe support details and locations

I am sure there are more that others can add.

For each line system you will need to determine the type and degree of weld testing

The contractor may elect to "prefab" some pipe at his shop location

I would leave the details of the "fabrication spool drawings" to the contractor

If you have a small job you can hire a turnaround contractor to do the work with sketches rather than engineering drawings.

In either case you should plan to have a engineering (piping engineer or designer) representative available to assist the contractor during the construction phase (solves problems as they come up).

Good luck!

RE: field engineering for piping erection at petrochemical plants.!!

Your question is too broadly based. Modular construction might apply. The use of semi-automatic welding processes might also apply. Excellent drawings are a must. Correct pipe spools area must.

RE: field engineering for piping erection at petrochemical plants.!!

Such questions without details will have useless answers. Indeed, Projects execution relies on Client/Contractor stringency w.r.t quality and safety requirements; as remaining construction aspects are manageable interms of progress boosting up to any extent required.

Though progress is an integrated part of quality and safety; it is highly recommended to go deeply in the previosly afformentioned inorder to acheive your targeted progress.

RE: field engineering for piping erection at petrochemical plants.!!

To get the fastest erection it is suggested that you modularise the plant and ship in the modules. Check out what they do in the oil and gas industry for rigs.

pennpiper and Leonardobetta's comment "Such questions without details will have useless answers" are dead on bullseye. The initial inquiry posting is too broad to offer a meaningful and specific response. Obviously, there are many factors that contribute to the complexity of the piping installation required including whether or not the site is a 'brownfield' or greenfield'
