Problems solved by technology

In this case, if the "2+2 construction method" is adopted, adding two full ships to two and a half ships, the space in the large dock will be wasted and the resources will not be effectively utilized.

Embodiment 1

[0096] A kind of ship building method of present embodiment, technical route

[0097] 1. Equipped with technical route

[0098] When the distance between ships is 1.2 meters, determine the precision control during the loading process and how to effectively expand the construction surface.

[0099] 1.1 Improve the production quality of sections, increase the magnitude of control, and implement no-surplus production and no-surplus loading for planar sections with small hull spacing.

[0100] 1.2 Improve the precision control during hoisting, especially for the special and difficult sections of some hoisting parts, research and formulate the hoisting plan, and implement it accurately.

[0101] 1.3 Use methods such as hanging blue construction to solve the problem of unfavorable expansion of the working face when the spacing is small.

[0102] 2. Coating technology route

[0103] In the "3+3 ship building method", ship painting is required to be applied at small intervals.

Abstract

The invention relates to a method for undock ballasting in ship building, which is particularly applicable to the building of Panamax bulk carrier in a dock and belongs to the technical field of dock building methods. The method is characterized in that: before large dock water injection, first-stage ballasting which comprises tail half ship ballasting and entire ship ballasting by three identical ships is performed; after the large dock water injection, second-stage ballasting which consists of primary large dock water injection, secondary large dock water injection, tertiary large dock water injection and quaternary large dock water injection is performed; and after ship ballasting is finished completely, water is injected into a large dock again till the water is 4.6 to 4.8 meters deep. The undock ballasting method is used in a '3+3 building method', realizes maximum utilization of dock resources, improves the utilization rate of docks and reduces an in-dock ship building period.

Description

technical field [0001] The invention relates to a ship building method, in particular to a docking and ballasting method, which is especially suitable for building a Panamax bulk carrier in a dock, and belongs to the technical field of dock building methods. Background technique [0002] Dock ship construction is affected by many restrictive factors such as the minimum distance between ships and between ships and dock walls, ship loading, ship coating, and ship undocking; The minimum distance between ships should be kept at 3-4 meters. The industry also generally recognizes this distance, and believes that reducing the distance will put forward higher requirements for loading, painting, docking, etc., and special demonstrations are needed to solve it. [0003] Jinglu Shipyard has a length of 369 meters and a span of 102 meters. The 75,200 dwt Panamax bulk carrier it undertakes has a length of 225 meters and a width of 32.26 meters. In this case, if the "2+2 construction met...
