The future of offshore wind

– Offshore wind will move to deep waters and worldwide deployment

– Floaters are the logical solution, as proven by the oil & gas industry

– Combined utilisation of wind with wave energy and/or other marine uses (aquaculture) is an attractive prospect if done properly:

• Large wave resource in many ocean areas

• More hours of renewable energy production and better price

(wind and wave are not always simultaneous, swell)

• Better use of marine space (MSP)

Snapshot Today

W2Power is a patented technology that uses proven platform technology and commercial, proven, offshore wind turbines. This allows major de-risking of wind power in deep waters.

• Can be built, installed, maintained and repaired world-wide, no deployment depth limits.

• Platform is wind-vaning, eliminates turbine yaw, lower cost and additional reliability

• Highest power per foundation: >10 MW wind, >12 MW with wave power)

- More efficient use of foundation, cabling, installation, operation & maintenance, decommissioning

- Lower LCoE than any other solutions (single-turbine floaters, independent wind & wave resource...)

- Excellent multi-use capability for additional economic activities

Current EU funded

project 2016-2018:

WIP10+

W2Power Technology: to TRL 4

Marinet projects “W2P Sea States Tests”, “W2P Mooring and wind” (2012-14)

• Facilities: Universities of Edinburgh (Scotland) and Cork (Ireland)

• Tank tests: Multi-directional sea states for performance validation (1:100 scale) with scaled-down full design of the mooring and initial wind force simulation.

• WEC’s characterization and global behavior in operational and survival modes

• Compatibility with other economic activities on the platform (aquaculture).

• Specific test campaign on the validation of the WEC’s (wave energy converters)and a new innovative control system developed, validated at 1:30 scale.

• TRL = 4 achieved after validation of the main components individually

W2Power Technology: to TRL 5

Marinet project: “W2P TRL5 Validation” (2015)

FloWave TT (Edinburgh): Current and Wave Tank.

Test programme Objectives:

• Fully achieve a Technology Readiness Level (TRL) of 5 for the W2Power platform

• Validation at 1:40 scale of the full scale design, mooring and wind force simulation.

• Validation of WEC’s influence on the platform,

operational and survival modes limits.

Configurations:

• Platform without WEC’s

• Platform with WEC arrays and max. wind force

W2Power Technology: to TRL 5

Results:

• The mooring design was fully validated w.r.t. stationkeeping and max. load in mooring lines.

• The maximum acceleration measured in normal and survival operations are in line with results of previous testing.

• Limited currents (< 1m/s full scale) don’t affect significantly the platform behaviour.

• The tests incorporated wind turbine inertias and forces simulation into the tests (thrust force control using system of lines and pulleys is an effective method).

• When the wind blows in a different direction than the wave angle, this does not significantly affect the wind power production.

• Measured RAO’s are similar to previous test results on the platform at 1:100 scale, when including rotating inertia of wind turbines and wind thrust effects.

WIP 10 + Project :

• Scale up and test at sea

• Prototype in the water by 2017 (WIP10+ Project)

– Approved for DemoWind Funding (H2020 ERANET Cofund)

– EnerOcean (project leader), Ingeteam, Ghenova (Spain), TTI (UK)

– TRL 6 by functional validation at sea (PLOCAN, Canary Islands)

“Satellite” projects to study added functionalities

(Multi-Use platforms / applications).

Business development: Equity need for next stages is clear. EnerOcean is active in

Multi-use Platforms. W2Power in TROPOS Project

• The TROPOS project (2012-2015), led by PLOCAN, has been one of five large EU funded projects on multi-use platforms.

• TROPOS focused the application of these platforms to be:– Suitable for Mediterranean, tropical and subtropical seas

– Integrating activities related to Transport, Energy, Aquaculture, Leisure

– W2Power proposed as a solution for “Mediterranean” seas.

This “Green & Blue” concept development is part of the EU

Oceans of Tomorrow project TROPOS (GA 288192) (2012-15)

W2Power WIP10+ unit

• Semisubmersible serially built “anywhere” and fit depth

from 50 m: Less site sensitive than fixed wind turbines

• Less than 72 m beam while built, potential manufacting

in many dry docks around the World (several in EU)

• Eliminates turbine orientation, allows for inclined towers,

reducing platform size and maintenance costs

• Same power (swept area) with less height than single 8-

10 MW turbine, less thrust torque, visual impact, ...

Benefits as Twin turbine platform

• Large but light-weight semi-submersible:up to 10 MW wind power on one foundation.

• Uses commercial WT’s for optimised mass & torque distribution, e.g. 2 x SWT-4.0-120

• Consider an interesting case for Mediterrean seas using suitable wind turbines, e.g. 2 x MHI Vestas V112- 3.45 MW. (Results FP7 TROPOS)

• Extensive testing of the «wind» only version in MARINET as base case for all models

• TRL 6 project on-going . 1:6 Scale prototype to be sea tested at PLOCAN (Canary Islands)

− Hub height: 90 m

− Distance between tower bases: 90m

− Power: up to 2 x5 MW (126 m rotor diameter)

− Operational draft: 15 m

− Displacement: 7500 m3, near 4000 tn of ballast (30m3)

Different Hybrid power production:

Different energy and aquaculture species and products combinations:

Wind/waver/PV and/or Salmon, seabream, amberjack, meagre, seabass, ¿tuna?

Seeweed, microalgae

Enabling additional research on multi-use energy applications, e.g.

Integration with electrical sub-station

On-board energy storage ( ICAES, flow batteries, …)

Offshore desalination

Environmental monitoring, survillience.

Vessel support

…

EXPLOITING DEEP WATER RESOURCES AT AFFORDABLE COST

Platform designed for Multi-Use from start

• Semi’s can be serially built “anywhere” and fit depths from 50m

• Fish cage and fish production equipment fully supported on

platform

• Up to 50% additional revenue from fish, on an 8-MW windpower

platform, at low added capex

• Can accommodate 40.000 m3 fish cage

Benefits as Multi-Use

• A full hybrid platform in development since 2009, today a Spain / Norway joint venture.

• Large but light-weight semi-submersible:up to 10 MW wind power on one foundation.

• Uses commercial WT’s for optimised mass & torque distribution, e.g. 2 x SWT-4.0-120, can be hybridised with 2 to 3 MW wave power and various other economic uses.

• Extensive testing and R&D in FP7 projects: MARINA Platform, MaRINET, TROPOS &Spanish national projects SeaMar, Offshore2Grid.
