Ship unloader transportation shipping technology

Abstract

The invention discloses a ship unloader transportation shipping technology, which comprises three stages, including loading, sea transportation and unshipping. The ship unloader transportation shipping technology has a special point that a way of combining a barge with a semi-submersible cargo ship is adopted to transport a ship unloader, i.e., the ship unloader is firstly rolled to the barge, themoulded depth of the barge and the freeboard of the semi-submersible cargo ship are added to achieve an elevation requirement of a user wharf, the problem that the ship unloader is difficult to realize roll unloading since the elevation of the user wharf is overlarge, and therefore, the successful transshipment of the ship unloader is guaranteed.

Description

technical field [0001] The invention relates to a technical method for roll-on and roll-off of a complete ship unloader on a wharf, in particular to a ship unloader transportation and shipping process. Background technique [0002] The bridge type ship unloader is referred to as quay crane or STS for short. It is generally installed on the shore of the port terminal. It is a professional equipment specially used for loading and unloading container ships at the container terminal. [0003] Usually, the bridge-type ship unloader is transported by large-scale transport ships to the user's wharf for delivery. Some of the unloading wharves have higher elevations, and the front of the wharf may have deep water depth and small tidal range. At this time, the plane of the transport deck of the large transport ship will be lower than the wharf surface, and its freeboard height cannot meet the requirements of the STS roll-off operation, and it cannot achieve the goal of safely berthing...

AI Technical Summary

Problems solved by technology

At this time, the plane of the transport deck of the large transport ship will be lower than the wharf surface, and its freeboard height cannot meet the requirements of the STS roll-off operation, and it cannot achieve the goal of safely berthing at the wharf for unloading and delivery

[0004] In addition, there may be other problems in the loading and unloading of STS: (1) After loading STS on the transport ship, the space on the left and right sides of the deck is narrow, which will cause difficulties in lashing

(2) According to the layout requirements of roll-on and roll-off tracks, the transport ship only allows a relative lateral error of 20 cm within a length of 100 meters, and the operation is difficult in the case of large swells

(3) The length of the bridge between the wharf and the transport ship is long. In order to ensure that the STS cannot enter the shore rail or the ship rail, the rail on the ship, the bridge and the shore rail must be in a straight line, and the deviation control accuracy is high.
