For China's shipbuilding, 2011 was extremely extraordinary, and the deepwater pipe-laying crane "Ocean Oil 201" was built for trial flight. The “Ocean Oil 201” ship built by Rongsheng Heavy Industry for China National Offshore Oil Corporation has a total length of 204.65 meters, a width of 39.2 meters and a depth of 14 meters. It is the first self-propelled deep-water pipe from domestic design and construction. Heavy ships can work in the global unlimited area except the North Pole. The completion of the deepwater pipe-laying crane "Ocean Oil 201" will fill China's gap in the field of deepwater equipment, and together with other deepwater development equipment built by CNOOC, China will become the world's 3,000-meter deepwater development club.

The development of the main marine engineering equipment and new marine engineering equipment is a strategic need for the development of national marine resources and an important part of the "Twelfth Five-Year Plan for the Development of National Strategic Emerging Industries." The manufacture of new offshore engineering equipment must be inseparable from advanced manufacturing equipment. In the construction of "Offshore Oil 201", the Trident CNC plasma cutting machine designed and manufactured by Farley Company contributed.

The shipbuilding industry is the earliest and most profitable industry in China. With more than 20 years, CNC cutting has been rapidly developed and widely used in major domestic shipyards, completely changing the inefficiency of manual and semi-automatic cutting. It fundamentally solves the bottleneck problem that has long plagued the cutting and cutting section of the ship during the construction process, and has become a booster for promoting the rapid growth of China's total shipbuilding volume. The cutting equipment is used in the shipbuilding industry, mainly for the hull steel plate blanking. The original blanking process needs to be staked out by the actual scale--making the prototype--drawing the line on the steel plate--using manual or semi-automatic cutting so many complicated The process, and the use of CNC cutting equipment for ship steel sheet cutting, its superiority is mainly reflected in saving man-hours, stakes platform and sample materials, while reducing the labor intensity of workers, greatly improving work efficiency. Therefore, time savings and ergonomics are the most important technical indicators required by the shipbuilding industry for cutting equipment. Specific to the characteristics of the equipment, the most obvious is the large gauge, generally more than 6,500 mm, so that the cutting of large-scale steel plate is not limited.

Farley Company is a research and development and production company of fine CNC plasma equipment specializing in FARLEY·LASERLAB brand under the Huagong Laser. As the world's leading brand of cutting and welding technology, FARLEY·LASERLAB products are widely used in ships, engineering machinery, locomotive manufacturing, aerospace, boiler containers, petroleum pipes, food machinery, textile machinery, electrical cabinets, metal manufacturing and other industries. For the characteristics of the shipbuilding industry, FARLEY·LASERLAB designed and produced the Trident CNC plasma cutting machine. Trident CNC plasma cutting machine uses a high-rigidity monolithic steel frame beam, which can withstand five times the weight of the same industry in the same cross-sectional area. The low-travel and high-beam construction ensures maximum stability and optimum combination while also facilitating the loading and unloading of large plates.

Trident CNC plasma cutting machine features high acceleration, no slag cutting, etc. It has torch collision protection, zero position control, programmable working zero, retrieving work zero, speed control, height control, automatic arc breaking diagnosis, laser Coordinate positioning, 250mm lifting range, user setting machining origin, zoom function, safety function and other functions. The equipment is suitable for precision machining of high quality thick plates, especially in the marine industry. The Trident CNC plasma cutting machine combines precision linear bearings, special rigid low-profile rails, AC servo motors and precision planetary gearboxes to ensure high precision, high rigidity and minimal backlash, and is easy to adjust. The application of the AC motor ensures an optimized acceleration, and the bilateral drive system of the rack and gear ensures accurate positioning and smooth movement of the torch. In this way, the Trident CNC plasma cutting machine is more flexible, more efficient and more stable than its competitors. In addition, the Trident CNC plasma cutting machine is also equipped with a plasma bevel cutting device independently developed by FARLEY·LASERLAB, which can cut the groove at the same time of cutting the material, eliminating the need for the subsequent beveling process after cutting, so in the middle, Thick plate cutting is far superior to general CNC plasma cutting equipment. Through the powerful 3D software CAM function, the device can complete complex bevel cutting work at one time, and can perform various types of bevel processing such as X, Y, etc. and can process batch processing of materials.

Combining good control, accuracy, practicality, user-friendliness, high reliability and perfect diagnostics, the Trident CNC plasma cutting machine is a weapon in the shipbuilding industry.

From the cutting of one piece of steel plate to the formation of so many steel plates, pipes and equipment to form a ship that can go to the deep sea of ​​three kilometers, the wisdom of man is really amazing. While we are proud of China's shipbuilding industry in the midst of a difficult situation, we must not forget that the Trident CNC plasma cutting machine plays an indispensable note of this melody. With the voyage of “Offshore Oil 201”, FARLEY·LASERLAB fine CNC plasma cutting equipment will surely open a new chapter for Chinese manufacturing in the shipbuilding industry with its excellent performance!
