1.0 IntroductionAs the current industrial development, seaports have become a very competitive and well-developed industrial field in our country, so seaport management must be smart enough to remain competitive with other seaports. Core competency has become a critical point for a port business to survive in the high competency industry. Core competency is a specific factor that a company considers central to the way the company or its employees work. It meets three key criteria:1. It is not easy for competitors to imitate2. It can be widely reused for many products and markets.3. It must contribute to the benefit experienced by the end consumer and to the value of the product or service for its customers. This report aims to show the importance of core competency elements in attracting customers to use the service provided by the seaport. The critical element can be demonstrated from the perspective of location, safety and productivity.2.0 LocationAccording to information from Matitime and the Port Authority of Singapore (MPA), strategic location will be the element important to the success of the seaport. The strategic location of the seaport can enable the port to have a good connection with the global transportation network, market accessibility, a global meeting place and an extensive communications network. Ports are heterogeneous and differ significantly, depending on their location, in the types of ships and cargo that they can handle and the services they offer. However, some broad categories can be used to distinguish them. Ports exist in several different locations: deep water ports, shallow water ports, and ports on inland waterways, lakes, and rivers. In terms of volumes, the majority of freight traffic by river passes through the middle of paper goods in the port in order to control port security. Productivity as the concern of efficient use in seaport, high productivity operating seaport can be effectively used in innovation and resources to increase the added value of products and services. It is the true source of competitive advantage that creates long-term economic viability and achieves a better standard of living for all. Cargo volumes and container traffic at seaports have now increased with the intensification of global trade and the geographic dispersion of production. Furthermore, maritime transport of goods is also experiencing strong growth and profound changes today. Thus, port authorities need to identify their core competencies and also manage the production of distribution activities across regions of the country to make the seaport more competitive and efficient..
