Embodiment Construction

[0041] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0042] like figure 1 As shown, the device used in the load test of the riser processing system of the present invention is mainly used in the riser processing system of the semi-submersible drilling platform as the test load. Device 1 (a riser in this embodiment) is a hollow cylinder with both ends closed, with a water injection hole on its upper end and a drain hole (not shown in the figure) on its lower end. In this way, it is convenient to inject water into the device 1 during the load test. During the load test, the weight is adjusted by injecting water into the device 1 to fulfill different test requirements. For example, according to requirements, the device 1 can complete a load test with a maximum load of 50T.

[0043] Preferably, a lifting lug 11 (usually 50T) is fixed on the...

Abstract

The invention discloses a device for a load test of a marine riser treatment system. The device is a hollow cylinder with two closed ends, wherein a water injection hole is formed in the upper end face of the hollow cylinder, and a drainage hole is formed in the lower end face of the hollow cylinder. The invention further discloses a method for the load test of the marine riser treatment system. The method comprises the following steps of: S1, transporting the device above a vertical trailer with a crane, S2, lowering a base of the device onto a bottom trolley of the trailer, S3, injecting water into the device to allow the device to reach the test weight, and S4, conducting the load test on the trailer with the device. The device for the load test of the marine riser treatment system adopts the hollow cylinder filled with the water for the load test, and the method for the load test ensures the accuracy of the load test of the marine riser treatment system, and greatly lowers the load test cost.

Description

technical field [0001] The invention relates to a test device, in particular to a device for load test of a water riser treatment system and a test method thereof, especially suitable for a semi-submersible drilling platform. Background technique [0002] Usually a semi-submersible drilling platform riser handling system includes a crane and a trailer (usually a riser crane and a riser trailer). When drilling, the drilling riser is hoisted from its standing area to the trailer by a crane, and then sent into the wellhead. [0003] The load test for the riser treatment system of the semi-submersible drilling platform generally needs to complete the load test of the crane (45T) and the trailer (32T). During the test, the crane and trailer complete their run over the entire work area under their test load. [0004] At present, there are mainly the following problems in the load test of the riser treatment system of the semi-submersible drilling platform: [0005] 1) During th...
