Icebreaker stem, installation method of icebreaker stem and ship

Abstract

The invention relates to the technical field of ship construction, in particular to an icebreaker stem, an installation method of the icebreaker stem and a ship. According to the icebreaker stem, a middle longitudinal wall plate is divided into an installation part and an icebreaking part, and a thickened outer plate is installed on the installation part, and the icebreaking part extends out of the thickened outer plate as an icebreaking structure, so that an integrated cast steel stem is not needed, and the cost is saved; and a transverse supporting structure is divided into two independent parts of a transverse rib and a reinforcing material, and the transverse rib and the reinforcing material are fixedly arranged between the thickened outer plate and the installation part, so that the internal structure is simplified, the installation is convenient, working in a narrow space is avoided, and the construction efficiency and quality of the stem are improved. The installation method ofthe icebreaker stem is used for installing the icebreaker stem, working in a narrow space is can avoided, and the construction efficiency and quality of the stem are improved. The construction efficiency and quality of the ship are improved through the application of the icebreaker stem, and the ship can be suitable for polar navigation icebreaking tasks.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an icebreaker stem, a method for installing the icebreaker stem, and a ship. Background technique [0002] The Arctic region is rich in energy reserves, and the Arctic route is shorter than the traditional Suez Canal route. Its business opportunities are becoming more and more prominent. However, the ice layer of the Arctic route is thick. At present, there are very few commercial transport ships capable of breaking ice, and professional icebreakers or other ships are needed. Ice-breaking equipment breaks the ice in advance to open up waterways, and the market prospect of polar ice-breaking transport ships is very broad. [0003] Icebreaking for polar ships mainly includes extrusion icebreaking and gravity icebreaking, both of which require a bow with icebreaking capabilities. However, the polar ice layer is thick, and the ice load on the structure is very large. In order t...

AI Technical Summary

Problems solved by technology

However, the polar ice layer is thick, and the ice load on the structure is very large. In order to ensure the icebreaking ability, the existing icebreakers all use an integrated cast steel bow or a complicated steel plate welded bow.

The one-piece cast steel bow requires steel casting materials to meet the low temperature requirements. Low temperature steel castings are expensive, and the production cycle of steel castings is long and the cost is high, which affects the production schedule and benefits of the shipyard.

The steel plate welded bow needs to weld a very thick lath to the outer plate of the bow, and then arrange a large longitudinal support structure and transverse support structure inside. The construction space is not conducive to production and affects the quality of ship construction
