A. COW concurrent method utilizes the crude oil stream being discharged, together with its associated back pressure, to supply the COW pipeline with crude oil. B. COW concurrent method can be achieved either by a "bleed-off' system from the main crude oil discharge pipelines for supply to the COW pipeline or by separate supply using a designated cargo pump. C. COW concurrent method: The normal minimum back pressure required for the operation of the COW guns is 8 kg/cm2. D. COW concurrent method: If supply is achieved by the bleed-off from the bulk discharge, then sufficient back pressure has to be maintained at all times. « Previous N…
