Schematic overview of HERCULES-C Work Package Groups.


The building blocks of the project HERCULES-C are the various Subprojects. The whole HERCULES-C Project is made up of 50 Subprojects. Each Subproject has several Activities. A cluster of related Subprojects makes up a Work Package and there are 10 RTD Work Packages. A pair of related Work Packages (WP) makes up a Work Package Group (WPG). The project comprises 5 RTD Work Package Groups covering a wide spectrum of marine engine research and development. The Work Package Groups are parallel Tracks of continuous R&D activities, which exchange high level information throughout the Project. The Partners work in groups at Subproject level, with specific targets. Work is consolidated into Work Packages and reported with written De  liverables or presented as machinery Prototypes. There are also 3 non-technical Work Packages for Administrative Management, Technical Management and Dissemination Activities.
