system over the design lifecycle. A system approach is chosen that gives sufficient
insight and at the same time is kept manageable. The prime operational functions,
namely wind energy production and mussel farming, are the main components of
the system identification diagram (Fig. 4.4). The diagram illustrates the two main
systems, their support systems, and the system boundaries. The two main systems
are supported by three support systems:
1. Operations & Maintenance System
2. Meteorological & Nautical Navigation System
3. Transport System (for details see Annex 1)
The physical building blocks of the systems (dashed lines) are defined as
‘functional packages’. The functions: power distribution onshore, mussel unload,
factoring, and distribution, are not included because it is assumed that these (sub-)
systems are available in adequate capacity.
