Problems solved by technology

At present, these two technical solutions are suitable for the construction of small-scale marine products in the construction of marine engineering equipment or in enterprises with large offshore docks. The construction of industrial products has the following disadvantages: (1) In the normal way of dragging and picking up, water has high requirements on the volume and weight of marine engineering products; (2) There are great safety hazards during the loading process. If there is a problem with the loading system, it w...

Embodiment Construction

[0022] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0023] The specific embodiment of the present invention is illustrated by taking a large-scale marine product pipe-laying ship as an example. The system and method for horizontal loading and launching of a pipe-laying ship with a maximum length of 153.6 meters, a width of 35 meters, and a weight of 12,500 tons can be used in When the size of the hull and the loading weight reach the limit of the entire loading system, the loading safety is guaranteed.

[0024] Such as figure 1 and figure 2 As shown, the present invention provides a system for loading and launching large-scale marine engineering products. The system includes a semi-submersible barge 2 and a towing system. The semi-submersible barge 2 performs loading and launching operations for large-scale offshore products under construction, and th...

Abstract

The invention provides an offshore engineering vessel loading and launching system and method. The system comprises a semi-submersible barge and a drag system, wherein a plurality of standby dragging winches are additionally arranged at the outer side of a barge slideway so as to be used for guaranteeing the safety in loading. The method is characterized in that the standby winches which are additionally arranged at the outer side of the barge slideway are used for dragging a main vessel body to the barge slideway from a wharf construction slideway, the barge is adjusted by discharging the water from different cabins of the semi-submersible barge, so that the horizontal dragging loading safety coefficient can be improved, the construction period is shortened, and the dragging cost is reduced.

Description

technical field [0001] The invention relates to a system and method for loading and launching ships, in particular to a horizontal loading system and method for large-scale marine engineering products and ships, and belongs to the technical field of marine engineering equipment and large-scale ship construction. Background technique [0002] Ship launching is the technological process of moving the ship from the construction area to the water after most of the shipbuilding project is completed. It is an important link in the shipbuilding process, and it is also a relatively complicated process. With the development of the economy and the advancement of ship manufacturing technology, the size and tonnage of ships are also increasing, and the force on ships and launching facilities during the launching process is also increasing, and the requirements for berths and other launching equipment are also increasing. high. [0003] In recent years, the scale of marine development ...
