Based on the experience of China Shipbuilding Co. Industry Culture Heritage Survey Project, this article describes the basic concepts and definition related to industry culture heritage preservation and re-utilization. The naval architecture and marine engineering industry cultures are significant in Taiwan's mechanical industry development due to their close relations with multiple industries and national defense industry. Suggestions to both industries are proposed: the most urgent is to keep important historical materials and documents, and the history research on these two industries. The re-utilizations of their culture heritage can also help them to improve their public relation, communication with general public, and to promote the value of the industry.
