1.Large ship base structure
Qidong COSCO Marine Engineering Co., LTD., the world’s largest offshore wind power installation ship solid pile frame (gearbox).
The jack-up wind power installation vessel Voltaire (N966), built by Qidong COSCO Marine Engineering for Jan De Nul Group in Europe, is specifically designed for the transportation, lifting and installation of offshore wind turbines, connectors and bases. The ship mainly consists of a more than 3,000 tons of winding pile crane, operating depth of more than 80 meters, payload of about 14,000 tons, can accommodate 110 people. The vessel is equipped with four pile legs to maintain stable working conditions on the sea surface and is equipped with a DP2 system. The product delivered this time is a total of 12 pieces of pile support (gear box) for the ship’s four pile legs, each weighing 90 tons.
The large ship base components weighing up to 90 tons are mainly made of 12mm thick steel plates. The welding requirements are extremely high and need to be done in full accordance with ISO5817-C standards. The main processing procedures are laser cutting, bending, welding and boring.

2.At the beginning of July 2017, our company produced 3 sets of special ship support structural parts for a large shipyard
Mitsubishi MVR45 for machining
Wuzhong double gantry mobile boring and milling machine for milling surface processing
3. 2,500 tons of duplex stainless steel plate for the world’s largest tonnage under construction 49,000 tons of chemical ships first ship supporting the project involves the ship plate material for the world’s highest grade of marine duplex stainless steel plate, in addition to corrosion resistance, mechanics, and welding and other performance requirements are more stringent requirements, the upper and lower surface roughness is required to be 5 microns or less, and the steel plate is not allowed to have both sides of the scratch Taking into account the special structure of the ship’s hull, ship plate Considering the special hull structure, extra wide plate width, longitudinal seam splicing, Ω-type (double Z-type) bending after welding, etc., this batch of molded products is extremely demanding on precision.
4.producing nearly 500 sets of ship components made of Q235B steel, with thicknesses ranging from 10mm to 12mm. These components required a meticulous process, including flattening, cutting, and welding, among other tasks.
5.Structural parts for ships
This batch of material is Q235B/25/30mm carbon steel material, due to the thickness of the material, we choose 2000T bending machine to do steel plate forming.
