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.
