#CMT# #/CMT# The device has a weight (11), a cable (12), a return unit (14) and a clamp (15) constituting a force application device provided for the permanent application of a force on a point of a section of a sub-marine pipe (10). The pipe buckles laterally under the influence of the applied force. The force is decomposed into three perpendicular components, where one component is perpendicular to an axis of the pipe at the level of the point of application of the force. #CMT#USE : #/CMT# Used for controlling lateral buckling of a sub-marine pipe e.g. simple rigid pipe and pipe-in-pipe, utilized for transporting a fluid e.g. hydrocarbon, and installed on a sea-bed (claimed), where buckling occurs under the effect of axial compression forces resulting from a conjugated effect of temperature and pressure of the fluid circulating in the pipe and of hydrostatic pressure, and the pipe is connected to an equipment e.g. manifold and crossing. #CMT#ADVANTAGE : #/CMT# Permanent application of the component perpendicular to the axis of the pipe permits to initiate and control lateral buckling of the pipe in a simple, easy, economic and effective manner, thus ensuring the integrity of the pipe and the equipment connected to the pipe. The intensity of the force for controlling the lateral buckling is less than that of the axial compression forces liberated during the buckling, thus utilizing forces having low intensity which can be generated by the device in a simple and economic manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic perspective view of a pipe with a lateral buckling control device. 10 : Sub-marine pipe 11 : Weight 12 : Cable 14 : Return unit 15 : Clamp. |
