Oil flushing, also known as oil cleaning, is a common process
in the construction of offshore platforms. In particular, the hydraulic system
has a high requirement for pipeline cleanliness, and usually the pipeline has
many branches. So it is difficult to divide the oil flushing package into
single line circuits, and the oil flushing quality of each branch cannot be
guaranteed. This paper builds models according to parameters of the pipeline
system, proposes to analyze the feasibility of the procedure using fluid
software simulation before oil flushing operation. Adjusts the oil temperature,
kinematic viscosity, flow control and other aspects, and then optimizes the oil
flushing procedure to ensure the quality and improve efficiency.
