Introduction to O-tube
Introduction to O-tube
This paper describes the O-tube, which is a new facility for submarine pipeline stability research. The O-tube comprises of a closed loop channel of water driven by an impeller. The impeller runs at a constant speed to provide steady flow and at sinusoidal speeds to generate oscillatory flows. The O-tube combines the capabilities of a conventional open channel flume (which provides steady current) with a U-tube (which provides oscillatory flow). The primary function of the facility is to physically model the stability of pipelines at a relatively large scale (typically 1/5) for large diameter pipelines (e.g. 40 inch gas trunklines) and at full scale for small diameter pipelines (< 10 inch). The specification of the motor and impeller is such that typical 100-year tropical storm conditions in 40 m to 80 m water depth on the North West Shelf (NWS) of Western Australia are comfortably generated within the performance envelope of the facility.

Abstract
This paper describes the O-tube, which is a new facility for submarine pipeline stability research. The O-tube comprises of a closed loop channel of water driven by an impeller. The impeller runs at a constant speed to provide steady flow and at sinusoidal speeds to generate oscillatory flows. The O-tube combines the capabilities of a conventional open channel flume (which provides steady current) with a U-tube (which provides oscillatory flow). The primary function of the facility is to physically model the stability of pipelines at a relatively large scale (typically 1/5) for large diameter pipelines (e.g. 40 inch gas trunklines) and at full scale for small diameter pipelines (< 10 inch). The specification of the motor and impeller is such that typical 100-year tropical storm conditions in 40 m to 80 m water depth on the North West Shelf (NWS) of Western Australia are comfortably generated within the performance envelope of the facility.
