While analyzing/supporting compressor (top suction /top discharge) inlet and outlet piping, first support(in my piping configuration liftup support)nearest to equipment nozzle is mandatory to avoid wnc displacement. It is not advisable to support it from m/c foundation as it will experience more vibration/layout constraint. Hanger support not possible as it will restrict gantry crane movement. How wnc condition can be satisfied. Please suggest to tackle this scenario.
