The paper examines current state and trends of the marine engineering and technologies around the world and attempts to extrapolate lessons for China’s development efforts. The major characteristics and tendency of the world ocean development come in the form of advanced equipment and technology, which are used as the main force for promoting ocean resource exploitation, ocean energy exploration and extraction as an important industry to the world's countries; living marine resources as a competitive focus, marine pollution management and prevention as the priority issue, and land-sea integration engineering as an important part for marine development. In-depth analysis of the aforementioned characteristics and trends allows us reach a list of important recommendations. Therefore China should strengthen its awareness of national ocean policy issues and enhance ocean development position as part of its the national development strategy; promote science and technology innovation; optimize marine industrial infrastructure and vigorously support emerging marine industries; improve its comprehensive management system and establish a mechanism for the coordinated development; strengthen protection of resources and the environment and keep sustainable exploitation on resource.
