Recently, the first 80-meter cruise rescue ship “Sea Patrol 22” of China Maritime System, built by Qiyiyi Design and Wuchang Shipbuilding Heavy Industry Co., Ltd., was delivered in Ningbo, Zhejiang Province. This is also the first 2000~3000-ton class in China. The sea cruiser filled the gap in the 80-meter class of the maritime sequence.
During the construction of "Sea Patrol 22", Wushu always carried out the idea of ​​"building a civilian ship", adhered to the quality concept of "100+1", and strictly controlled the construction process in strict accordance with the requirements of "six fine management" to overcome A number of technical problems have made significant progress in precision management, comprehensive cabin layout, shafting construction, and interior optimization, ensuring the orderly conduct of various tests. During the trial period, the performance indicators of “Sea Patrol 22” fully meet the requirements of drawings and specifications.
The construction period of “Sea Patrol 22” from the start of construction to the launching of the ship was shortened by more than one month compared with the previous similar ships, and the launching node was two months earlier than originally planned. The first-class product rate of the product rating project is 100%. The qualified rate of product inspection is 99.5%, the pass rate is 100%, and the pass rate of X-ray flaw detection is 99%. The shipbuilding cycle and quality are both win-win. The ship's cruise law enforcement equipment is fully equipped, and the cruise law enforcement capability is further improved, achieving an air-sea integrated rescue system within the scope of 2000KM.
The coastline of Zhejiang has a total length of 6,700 kilometers, accounting for 20% of the country. After the "Hai Teng 22" was compiled by Zhejiang Maritime Safety Administration, it is of great significance to speed up the pace of Zhejiang coastal cruise rescue integration construction, create an efficient, green and clean navigation environment, enhance coastal water supervision capability, and safeguard national sovereignty and maritime rights and interests.

Anchor Drilling Machine

The anchor drilling rig is mainly used in hydro power stations, railways and highways, in order to prevent and control various geological disasters, anchoring operations are carried out on landslides and dangerous rock masses.It is mainly used in landslide and dangerous rock anchoring projects in tunnels, railways, highway slopes and other kinds of geology, especially for high slope rock anchoring projects. Drilling operations consume less manpower and material resources, have high construction efficiency and high safety factor. It is also suitable for the construction of deep foundation pit support, reinforcement hole for anti-float anchor and foundation grouting, blast-hole in blasting project, high pressure sprinkling stake and tunnel pipe support hole, etc..

The drilling technology with casing of anchor drilling rig is designed to solve the problem that complex rock layers cannot be holed. The drill bit impacts rock continuously, and the broken rock is blown to the ground by the air pressure discharged from the gap between the casing and the drill pipe. The drill pipe and bit can be lifted after punching the hole, and the casing is placed in the middle of the rock layer, so that the rock layer doesn't collapse.
