WP5 Commercial-scale device specifications



Last updated: 19 December 2016

Lead: Head of Commercial Design Jørund Moseid

Work in this WP is carried out by FPP AS NUF, supported by FPP A/S and FPP Ltd as necessary.

Objectives of the work package:

  • Establish commercial-scale product specifications for manufacturing commercial devices/arrays.
  • Maintenance of IPR and protection of new results or alterations.
  • Data review and validity.

Key focus is to further develop and define product and site specifications/restrictions for the P80 UK device and get third party data review on design and data from FPP’s extensive experimental test programs.

Summary of work performed in WP5


Environmental data gathering

Since the identification of the two potential project sites FPP Ltd, supported by FPP A/S, has collected a range of environmental data for these sites to help inform the design process.

In period 3 FPP Ltd has drafted and submitted the report D5.1 covering the environmental data for the two selected sites. The report provides an overview of the data collected to date as well as detailing the data that will be required to progress the development of the site and technology. An overview of the development process has been produced by FPP Ltd and will be built upon to detail the exact data sets and studies required.


Definition of realistic design restrictions

Design Basis and Functional Specification has been issued to sum up the requirements for the concept period of the P80 design adaption. This document forms the basis for the ongoing design work. The design basis issued in draft revision has been commented by the third party Lloyds Register. A new revision has been issued with an updated mapping of requirements to meet IEC 62600 and IEC61400. The mapping forms the basis for further technology evaluation to be carried out in the next part of the work.


 Design adaption based on restrictions

The design work carried out as part of this task is concentrated around the following focus areas:

  • Global design of the platform - now completed.
  • Hydrodynamic design - optimisation of the first issue of design has been carried out.
  • Wave absorber - the overall geometry of the upper section of the wave absorber has been optimised to minimise forces and reduce overtopping, making the motions and forces more predictable, thus minimising risk.
  • Power Take Off (PTO) design - the PTO design adaptation has been initiated with our industry partner and will start in the next period as a succession of the global design and the development of the platform itself.
  • Electrical system design - two potential vendors have been identified and one proposal for a configuration has been used as a basis in the modelling of the mooring system. Next step here is to complete the electrical load list for emergency/intermittent power consumption as well as developing the power generation system based on the input from the WTG design and the WEC design.


IP assessment

FPP has worked actively internally and with partners on further protection of already obtained IP in overseas markets.

Together with an IP consultant a patent/idea pipeline document has been developed as steering tool. This document is continually used at design and review meetings to keep continued focus on securing protecting and increased valuation.
