Embodiment Construction

[0032] The present invention is a jack-up drilling platform cantilever beam heavy load test system, such as figure 1 As shown, it includes a main hull 12 supported by legs 13 above the sea level, a cantilever beam 11 horizontally located on the main hull 12 and extending to the sea level, a drilling platform 10 at the end of the cantilever beam 11 and a derrick 1, The top drive 2 located on the upper part of the derrick 1 and the ballast water barge 8 connected to the top drive 2 floating on the sea level; the drilling platform 10 is provided with a stand area simulating the actual weight; connected.

[0033] Such as image 3 As shown, there are eight lifting points arranged in a balanced manner on the barge 8, and the lifting points are arranged in two rows symmetrically along the long axis of the barge 8. Between the barge 8 and the top drive 2, there is a device for converting the eight-point hoisting into two-end hoisting. specific tooling. Such as Figure 5 As shown, ...

Abstract

The invention relates to a system and a method for cantilever beam heavy-duty test of a self-elevating drilling platform. The system comprises a main boat body, a cantilever beam, a drilling platform, a derrick, a top drive and a water ballasting type barge, wherein the main boat body is supported by pile legs and positioned above the sea level, the cantilever beam is horizontally positioned on the main boat body and extends above the sea level, the drilling platform and the derrick are positioned at the end part of the cantilever beam, the top drive is positioned at the top of the derrick, and the water ballasting type barge is connected with the top drive and floats on the sea level; a stand zone simulating actual weight is arranged on the drilling platform; and the top drive is connected with the barge through a steel wire rope. Three tests are carried out by using the system. The system and the method have the advantages that the correct implementation of the test scheme can be ensured, and at the same time, the test cycle can be shortened; and through the universalization of tool design, the system and the method can adapt to the cantilever beam heavy-duty tests of various self-elevating drilling platforms, thereby reducing cost.

Description

technical field [0001] The invention relates to a jack-up drilling platform, in particular to a cantilever beam heavy-duty test system and method of the jack-up drilling platform. Background technique [0002] With the development of society and the progress of science and technology, human beings' demand for energy is also increasing. Offshore oil rigs are being built in increasing numbers, and cantilever beam rigs are popular because they can drill multiple cluster wells in one location. [0003] During the entire commissioning process of the drilling platform system, the cantilever beam heavy-load test is very critical. It can determine the load capacity of the cantilever beam at different positions and clarify the future operating load of the platform, which is related to the safety of the entire platform. [0004] Since the test causes the cantilever beam and hull to reach the maximum design bending moment, shear force and deformation, any slight negligence may cause g...
