The high-grip anchor is the preferred equipment for large-tonnage ships, and is recognized by domestic and foreign ship owners for its small weight and large grip. At present, the design of anchor bolts and anchoring platforms for large-capacity anchors in China has been entrusted to foreign enterprises or institutions, which not only increases the cost of ships, but also causes the delivery period to be unguaranteed, and the market competitiveness of shipbuilding enterprises declines.
In response to this problem, the heavy industry of the barge has invested in technical strength and successfully solved the technical problems of the large-grip anchor flipping space and the difficulty of fitting. The principle of gravity sliding inner tilting is adopted to design the anchor bolts, anchoring platforms and anchor chain cylinders. The patents granted by the State Intellectual Property Office have been obtained, which fills the blank of this technology field in China.
The successful application of the invention on the 159,000-ton crude oil ship built by China Shipbuilding Heavy Industry Co., Ltd. for China Ocean Shipping Group Corporation and TK Shipping Company of Canada and its subsequent new ships fully demonstrates the advanced nature and practicability of the technology. The ship construction cost has been greatly reduced, the efficiency has been improved, and the guarantee for the construction of various large ships in China has been provided.
