Offshore engineering vessel loading and launching system and method

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 ...

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 will cause irreparable losses; (3) The product integrity is low when the product is closed after being loaded in sections, and the closing accuracy in the dock is high, and the requirements for the coating of the cabin are also high, and it is not conducive to equipment installation

[0004] However, there are many other factors that affect the safety of launching a ship. If the various factors are not analyzed before the launching of the ship, emergencies may occur due to poor consideration in advance , causing immeasurable losses
