With the introduction of one belt, one road strategy, the coastal economy of China has developed rapidly. This has also caused the increasing number of marine engineering projects, especially marine architecture. Obviously, the ocean engineering project has become an important factor affecting the national economic development, which is a technology and capital intensive and complex project. For marine construction engineering, we must do a good job in cost control, which will directly affect the quality management and budget management of the project. Under the new market environment, marine construction engineering must take project development as the main profit model, which requires us to control the cost of the whole process of the project. Through Early value management, residual value estimation method and other methods, we can control the cost well, which can also better control the progress and budget. Firstly, this paper analyzes the main characteristics and calculation methods of cost control. Then, according to the actual distance of Dingcheng project in Yantai. Finally, some suggestions are put forward.
