Abstract

Provided is a steel catenary riser integral analysis test apparatus with pipe-soil interaction taken into consideration. The apparatus includes a displacement sensor, an extension case, a main case, a pillar, a motor, a nut, a leading screw, a supporting column, a force sensor, a bracing frame, a controller, a model riser, a wheel carrier, pulleys, cylinders, supporting rods, a model seabed, bolts, and a fixing buckle. The bracing frame is disposed on the main case. The controller is disposed on the right side of the bracing frame. The pillar is disposed on the bracing frame. The motor is disposed on the pillar. The motor is connected to the controller through a lead, and also is connected to the leading screw through a shaft coupling. The left end and the right end of the leading screw are both arranged on the supporting column. The advantages of the apparatus are that excitation motions with different forms can be provided to the top end of the model riser, so a user can carry out an analysis test more comprehensively.

Description

technical field [0001] The invention relates to an overall analysis test device for a steel catenary riser considering the effect of the pipe and soil, and belongs to the technical field of marine engineering. Background technique [0002] As the main artery of offshore oil and gas production, the riser system plays a pivotal role in the development of offshore oil and gas resources. With the increase of water depth, the invention of deep-water steel catenary riser gradually shows unique advantages in cost control, applicable water depth and adaptability, and replaces traditional riser, becoming a low-cost and high-efficiency riser solution for deep sea especially resource development. As a system connecting offshore floating devices and subsea pipelines, it is widely used in various water depth development projects. [0003] Chinese Patent Publication No. CN201965061U, the publication date is September 7, 2011, and a deep water riser fatigue test device is disclosed in the...
