Abstract

The invention provides a semi-submersible type crane platform ballast system and method. The ballast system comprises multiple ballast tanks and ballast pipelines. The multiple ballast tanks are arranged in stand columns of a port and starboard and distributed in the height of the stand columns. The ballast pipelines are arranged in the stand columns and cross bracing and make all the ballast tanks in the port and the starboard communicated. Transfer of ballast water from the high position ballast tank to the low position ballast tank can be achieved through the ballast pipelines and gravity among the ballast tanks of different heights in the port and the starboard, work of a ballast pump is not needed, and the rapid reaction capacity of the ballast system is improved.

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a fast ballast system and a ballast method for a semi-submersible lifting platform. Background technique [0002] As my country's economy continues to grow at a high speed, the insufficient supply of oil and gas resources will become the main contradiction hindering economic development. In order to increase the share of oil and gas resources, the development of offshore oil and gas has become the strategic focus of my country's sustainable energy development. [0003] At present, the ballast system of semi-submersible offshore platforms is mainly the traditional pump ballast system. For heavy-duty lifting platforms, the pump ballast system has poor quick response performance and low efficiency, and even affects the construction period of the project, which generally takes 3 to 4 hours. [0004] Traditional ballast systems include ballast pumps, system piping and vari...
