Device classification
Why do it:
move away from visual classification
Device classification
Why do it:
move away from visual classification
Increase detail
Increase use
Device classification
What is it:
Based upon physical principals of operation
Tidal energy - Primary method of
energy conversion used in
hydrodynamic subsystem
Device classification
What is it:
Based upon physical principals of operation
Wave energy – Exciting forces on
primary conversion component
Device classification
What is it:
Based upon physical principals of operation
Addressed by device subsystem

Device classification
What is it:
Based upon physical principals of operation
Addressed by device subsystem
Generic - Basic form of foundation /
anchor
Device classification
What is it:
Based upon physical principals of operation
Addressed by device subsystem
Medium level of description allows for comparison and differentiation
Tidal energy device descriptors
Device classification
Who will benefit:
Anyone requiring a base level of detail in order to conduct an equitable comparison of devices
e.g. Funding bodies, NGOs, device customers (utilities)
Performance specification
Why do it:
classify wave and tidal arrays
address differences between single devices and arrays
guidance on array metocean conditions
Performance specification
What is it:

Summary of WP5
• WP5 to be seminal work on arrays (can be built upon by future work)
• Qualitative Guidance formulated to be quantified by future work
• Designed to both inform and guide self-information concerning arrays
