Ships and methods of construction

Abstract

The invention provides a ship and a construction method thereof. The ship includes a deck, two opposite side bulkheads, rails and a crane; the side bulkheads are erected below the deck and are enclosed with the deck to form a cargo hold; at least one side bulkhead has a hatch; the rails are installed on the deck The lower surface of the tank extends between the two side bulkheads and corresponds to the position of the hatch; the crane is installed on the track and can move along the track so as to be accommodated in the cargo hold or extend out of the cargo hold through the hatch; The working range of the crane covers the cargo hold. The construction method includes: prefabricating the deck sub-section and the track segment respectively, wherein the track segment contains a track; assembling the track segment to the deck sub-section and welding and fixing it to form a deck segment with a track; The crane is installed on the track of the deck section to form the first hull section; the first hull section is hoisted and closed to other hull sections. The ship of the invention can improve the efficiency of cargo transmission, and the construction method can reduce construction difficulty.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship and a construction method thereof. Background technique [0002] Antarctic krill is the single species with the largest biomass found on the earth, and its total amount is conservatively estimated to reach hundreds of millions of tons. In the context of the continuous decline of global fishery resources, Antarctic krill is expected to become the largest protein resource pool for human beings in the future. The krill boat processes the caught krill into krill meal on board through the unique processing system on board and packs it in bags for easy storage, transportation and sale in units. In order to meet the unique needs of cargo transportation after krill fishing operations, it is necessary to hoist and transport the cargo in the cargo hold by a crane. [0003] In ships of some related technologies, the cargo hold of the ship is usually provided with a hatch on the deck ...

AI Technical Summary

Problems solved by technology

In this structure, the efficiency of cargo transmission is low, and when the ship is built, it is difficult to control the accuracy of the installation position of the crane and the crane track on the deck, and the construction is difficult
