Rocker overturning testing method for jacket launching barge

Abstract

The invention relates to the technical field of marine installation testing, in particular to a rocker overturning testing method for a jacket launching barge. In the testing process, the rocker overturning lifting force is provided through a crane in a dock, and the adjustable and controllable crane lifting force is capable of guaranteeing the precise and safe regulation and control in the rocker overturning process and convenient for controlling the rocker to statically locate at a position to be tested to test. The rocker overturning testing method for the jacket launching barge does not need counterweight iron and the like testing fixture, the testing fixture preparation before testing and the tail-in work after testing are greatly reduced, the testing period is shortened, the efficiency is improved, the testing process can be performed in the dock, the mooring testing period of the launching barge at the wharf is shortened, and the wharf resource and testing cost can be saved.

Description

technical field [0001] The invention relates to the technical field of ship device testing, in particular to a rocker turning test method for a jacket launching barge. Background technique [0002] The rocker arm of the launching barge is a key system on the launching barge. It is the main load-bearing system and force-bearing system of the jacket and other equipment during the launching process. , when the jacket slides along the launching barge track to the stern of the launching barge, the rocker arm will drag the jacket up and turn over together under the double action of the jacket pressure and the stern inclination of the launching barge to push the jacket into the water, and finally the jacket leaves the barge, The rocker arm stands at the stern of the launching barge. In the field of shipbuilding, after the production and installation of the rocker arm is completed, a series of overturning tests are required, and during the test, check the contact between the rocker...
