An integrated vessel data management method, comprising: receiving vessel data collected from at least one vessel equipment ; converting the collected vessel data to a standardised data format by using an integrated vessel data management apparatus to apply a vessel data model, VDM, to standardise and define data associated with the vessel equipment of each marine vessel, and to objectize all devices from the marine vessel itself to an end sensor and define a relationship between said objects and attributes thereof, wherein the VDM defines a mapping relationship between a non-standardised format and the standardised data format, the mapping relationship being defined by a VDM configuration file that provides a mapping tool to a user of the integrated vessel data management apparatus , said VDM configuration file including metadata for defining information of each marine vessel based on the VDM, including: a vessel part describing the arrangement structure of vessel equipment in each marine vessel and hierarchically defining vessel equipment by systematic classification; a system part defining a system that collects vessel data from the vessel equipment in each marine vessel; and a data type part describing the structure and attribute of the vessel data collected from the vessel equipment in each marine vessel; and transmitting the converted vessel data in the standardised data format to an external device , wherein the integrated vessel data management apparatus identifies each vessel data according to a VDM Path in transmitting and receiving vessel data based on the VDM, the VDM Path comprising identification information for identifying particular vessel data on the VDM. receiving vessel data collected from at least one vessel equipment ; converting the collected vessel data to a standardised data format by using an integrated vessel data management apparatus to apply a vessel data model, VDM, to standardise and define data associated with the vessel equipment of each marine vessel, and to objectize all devices from the marine vessel itself to an end sensor and define a relationship between said objects and attributes thereof, wherein the VDM defines a mapping relationship between a non-standardised format and the standardised data format, the mapping relationship being defined by a VDM configuration file that provides a mapping tool to a user of the integrated vessel data management apparatus , said VDM configuration file including metadata for defining information of each marine vessel based on the VDM, including: a vessel part describing the arrangement structure of vessel equipment in each marine vessel and hierarchically defining vessel equipment by systematic classification; a system part defining a system that collects vessel data from the vessel equipment in each marine vessel; and a data type part describing the structure and attribute of the vessel data collected from the vessel equipment in each marine vessel; and a vessel part describing the arrangement structure of vessel equipment in each marine vessel and hierarchically defining vessel equipment by systematic classification; a system part defining a system that collects vessel data from the vessel equipment in each marine vessel; and a data type part describing the structure and attribute of the vessel data collected from the vessel equipment in each marine vessel; and transmitting the converted vessel data in the standardised data format to an external device , wherein the integrated vessel data management apparatus identifies each vessel data according to a VDM Path in transmitting and receiving vessel data based on the VDM, the VDM Path comprising identification information for identifying particular vessel data on the VDM. <EOS>
