Mawei Shipbuilding's first 23,500 ton product oil tanker successfully delivered
On January 19, 2018, Mawei Shipbuilding signed a contract with Singapore's OCEAN TANKERS for the construction of 10 large 23500DWT oil tankers. This cooperation is Mawei Shipbuilding's insistence on “precision of new products”, strengthening innovation drive and promoting product structure from industry. The result of the development of low-end and medium-to-high-end transformation also reflects the cooperation concept of mutual support and mutual benefit with OCEAN TANKERS. The "OCEAN CLOVER" has a total length of 155.00m, a width of 36.00m, a depth of 15.20m, a draft of 9.00m, a capacity of 40,800 tons, a speed of 14 knots, and an American Bureau of Shipping (ABS). It also has the function of oil transportation and refueling. It adopts double-engine double-blade double rudder design, and has a slanting mast with a bulbous nose. It is equipped with a hybrid water jet propeller for the Southeast Asia route near Singapore. In the process of building the ship, Mawei Shipbuilding has been striving for excellence and skill, and has overcome the difficulties and challenges of the first ship. In the profile cutting process, the advanced high-precision CNC profile cutting production line is adopted, and the robot arm with 360-degree rotary cutting is provided. The new production line directly programs the profile cutting data in the drawing design stage, and can smoothly complete the processing of various types of parts. , greatly improving the production efficiency and product quality of the product. During the construction of stainless steel pipe, the integrity of the cargo tank is a difficult point to break through. There are 2,200 stainless steel pipes in 14 cargo tanks, each of which has about 120 welds, each of which must be strictly inspected. . The project research team optimized the stainless steel welding process, and prepared the stainless steel pipe assembly auxiliary tooling in advance to effectively improve the pipe installation production efficiency. The pass rate of the stainless steel pipe inspection was 100%, which was highly praised by the shipowner. In the ship construction process, according to the modern shipbuilding model concept, and guided by the intermediate products, the unit armor is actively promoted. The “OCEAN CLOVER” cabin area has a total of 13 units, and the bottom of the cabin has been modularized for the first time in large-scale piping units, effectively reducing the cycle. "OCEAN CLOVER" adopts double rudder twin propeller propulsion system, which is more demanding than conventional single propeller single rudder ship. In addition to the accuracy requirements of the axle rudder system, it also controls the relative parallelism between the parallel and double rudder systems. And relative front and rear positions. The project team starts the precision control from the sub-group, strictly controls the segmentation and the welding deformation related to the shafting and rudder systems, and ensures that the relevant data is within the scope of the standard, ensuring smooth delivery and successful completion in the sea trial. Performance test of twin-machine twin-blade and single-machine single-blade. |
