Dalian marine propulsion VLOC super large marine propellers successfully accepted and delivered

On June 2, 2017, the super-large marine propellers supplied by Dalian Marine Propulsion Co., Ltd. for China's 400,000-ton ore sand carrier (VLOC) were successfully accepted and delivered to Shanghai Waigaoqiao Shipbuilding Co., Ltd.
 
        It is reported that the propeller has a diameter of 11.2 meters, a finished product weight of 71.86 tons, and four leaves. It is a double-ship class of DNV GL and China Classification Society (CCS). The design of the Shanghai smald propeller propeller is jointly established by Dalian Ship Push and 702. The company's design is the largest diameter marine propeller in the world. The design of the propeller has been transferred to several international pool tests in Norway and Sweden. In the competition of fair comparison test, it has defeated three international famous propeller design companies in the rapid test and air bubble test.
 
        The propeller has a large diameter and a side slope angle of 24.5 degrees, which is close to the large side-inclined propeller. It is also unique in the history of oars in the world. Its material properties and numerical control processing requirements are high, and it is difficult to customize the tooling. Through careful organization and careful arrangement, Big Push Company has overcome many difficulties and successfully completed the manufacturing task in 60 days, creating a new record for the manufacture of super large marine propellers. The successful and smooth delivery of the first product of this product once again demonstrates the competitiveness and brand advantage of Dalian Shipbuilding in the international propeller market.
 
        Since 2016, Dalian Shipbuilding has contracted 30 orders for the world's largest and most advanced 400,000 tons VOLC propellers. The propellers delivered this time are the first propellers in this batch of orders, and 29 of them will follow. Delivered between 2017 and 2018.
