2. Supply chain

i. O&M

ii. Bottlenecks/restrictions

3. Electrical connection

i. Configuration

ii. Scaling

iii. Power quality

4. Spatial layout

i. Device/site matching

ii. Interaction effects

iii. Installation, O&M

Performance assessment

1. Performance specification

i. Devices within an array

ii. Whole array

2. Reporting

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

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
