Dear Professionals,

In most oil and gas projects, loads are divided into continuous, intermittent and standby loads; are summed up separately and then applied with 1, 0.5, 0.1 diversity factors for continuous, intermittent and standby respectively. Then,

maximum running load = continuous loads*(1.0) + intermittent loads*(0.50)

Peak Load = continuous load*(1.0) + intermittent loads*(0.50) + standby loads*(0.10)

Are those applied diversity factors: 0.50(for intermittent), 0.10 (for standby) an industry practice? or
is there a code that recommends these factors?

Please reply..
