Design of a Spherical Leak Detector for Submarine Oil Pipelines

Abstract:

Spherical leak detectors can detect very tiny leakage in pipelines and have low risk of blockage. It is very suitable for submarine oil pipelines. In this paper, the passing ability of the detector in the vertical segment of a pipe was studied using CFD simulations. The simulation shows that the drag on the detector by the flow inside the pipe is related to the flow velocity V and the diameter ratio λ (d/D).We found it’s a good choice when λ ranges from 0.7~0.8, and a spherical leak detector (λ=0.8) is designed. The field experimentation shows that the prototype of the detector can go through within normal economical flow velocity (0.7m/s-1.5m/s) in 8 inch pipelines.
