Problems solved by technology

[0003] At present, the domestic and foreign surface ships used for marine transportation, deployment and recovery of marine equipment are mainly divided into: offshore engineering ships with lifting capabilities (such as surface support ships with A-frames, floating cranes and wind power installation ships, etc.) A semi-submersible ship with high capacity; the former has limited lifting capacity of the A-frame, and the floating crane or wind power installation ship is equipped with a large crane, which is not flexible enough; while the latter has a complex submersible-floating operation process, takes a long time, and is expensive

Abstract

According to the multifunctional workboat with the buoyancy adjusting carrying platform and the operation method of the multifunctional workboat, during marine transportation, marine equipment can becarried on a loading deck of a water surface boat in a dry mode and can also be tied and fixed to the deck of the buoyancy adjusting carrying platform; during laying, the ocean equipment is transferred to the buoyancy adjusting carrying platform by means of a rail and a flatcar on the loading deck, and laying and recycling operation of the ocean equipment is implemented by means of linkage of a buoyancy adjusting system of the buoyancy adjusting carrying platform and a plurality of winches on the main deck of the working ship. The buoyancy adjusting system of the carrying platform is used forbalancing the gravity and buoyancy of the carrying platform and the ocean equipment as a whole. Therefore, the requirement for the performance of the winch on the main deck is greatly lowered, only small tension needs to be provided to maintain the depth of the carrying platform, and the carrying platform is lighter, more flexible, economical and reliable compared with an A frame, a floating craneand the like used for offshore hoisting.

Description

technical field [0001] The invention relates to the technical field of multifunctional workboats, in particular to a multifunctional workboat with a buoyancy adjustment carrying platform and an operation method thereof. Background technique [0002] In recent years, with the vigorous development of marine resources at home and abroad, many new fields and markets have emerged, such as offshore oil production, offshore wind power and marine ranching, etc. Marine equipment has various forms and functions. The demand for maintenance support is increasing day by day, which puts forward higher requirements on the capabilities of existing ships. [0003] At present, the domestic and foreign surface ships used for marine transportation, deployment and recovery of marine equipment are mainly divided into: offshore engineering ships with lifting capabilities (such as surface support ships with A-frames, floating cranes and wind power installation ships, etc.) A semi-submersible ship ...
