          In the year 2007, a joint venture Shanghai Marine Propeller Design Co., Ltd. was found by DMPC and China Ship Scientific Research Center. Then we leaped to a new stage that we can design and research marine propellers by ourselves. There is a team of experts who are specialized in propeller design and hydrodynamic performance research in this design company. They have decades of years' of experience of design and model tests, and advanced theories come out of tests for propeller efficiency, cavitation, vibration, noise and strength, which allows to best performance propellers. Now we can design and manufacture different types of marine propellers, and the performance can fully meet the needs of the shipyards and owners.
