The building blocks of the project HERCULES-2 are the various Subprojects. The whole HERCULES-2 Project is made up of 34 Subprojects. Each Subproject has several Activities. A cluster of related Subprojects makes up a Work Package and there are 8 R&D Work Packages. A pair of related Work Packages (WP) makes up a Work Package Group (WPG). The project comprises 4 R&D 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 Deliverables or presented as machinery Prototypes. There are also 3 non-technical Work Packages for Administrative Management, Technical Management and Dissemination Activities.


The HERCULES-2 overall structure is shown in Table below.
