W2Power: Snapshot Today ▪
W2Power is a patented technology that uses proven platform technology and offshore wind turbines available today. This allows major de-risking of wind power in deep waters.
▪
Can be built, installed, maintained and repaired world-wide, at any sea depth.
▪
Platform is wind-vaning, eliminates turbine yaw, lower cost and increased uptime
▪
Industry leading power per foundation and mooring/connection point: 12 MW - More efficient use of foundation, cabling, installation, operation & maintenance, decommissioning - Lower LCoE than any other known contenders (on specific sites) - Excellent multi-use capability for additional economic activities
▪
A prototype will be demonstrated at sea in Canary Islands: Project DEMOWIND WIP10+
W2Power Key dimensions • Large but light-weight semi-submersible: up to 12 MW wind power on one foundation. • Uses commercial WT’s for optimised mass & torque distribution, e.g. 2 x SWT-6.0 • Extensive testing in MARINET • TRL 6 project on-going . Has completed TRL advancements using 8 test campaigns in 4 laboratories in 3 countries
• 1 : 6 Scale prototype to be sea tested at PLOCAN (Canary Islands)
Main Dimensions − Hub height: 90 m
− Distance between tower bases: 90m − Beam during construction: 72m − Power: up to 2 x6 MW (aprox 132 m rotor diameter) − Operational draft: 15 m − Displacement: 7500 m3, near 4000 tn of ballast
W2Power Economics and benefits ❖ The best 12MW platform solution is to use two 6MW turbines: Lower loads (static and dynamic) on the floater ▪ Benefits of platform self orientation ➢ Elimination of active yaw system in the turbines, responsible for long downtime periods and expensive single breakdowns.
➢ Self-orientation of the platform means less absolute misalignment (no yaw threshold). Platform allows for up- or downwind turbines. ➢ Allows closely spaced turbines on leaning towers (smaller platform) ▪ Benefits of leaning towers and twin wind turbines
➢ Allows for smaller floating platform (< rotor diameter) and vertical reach of nacelle from a barge (cheaper O&M) without crane vessels ➢ Smaller wind turbines for the same power • Lower cost per MW and today’s technology
• Lower height. Cheaper assembly and maintenance ▪ Benefits of a light but big semi-submersible platform, ➢ You can have smaller volume and draft in the columns for the same stability (reduces construction steel need)

W2POWER MULTIUSE PLATFORMS EnerOcean was a member of the FP7 Project TROPOS (2012-2015), led by PLOCAN, Ocean of Tomorrow call, previous to current BLUE GROWTH. TROPOS focused in the development of multiuse solutions that: Suitable for : • Mediterranean Sea • Subtropical Seas • Tropical Seas
Integrate aspects related to: • Transport • Energy • Aquaculture • Leisure
Have modular design: • Central unit with internal and external modules • Multiple satellites to provide energy and to produce offshore aquaculture products
W2POWER MULTIUSE PLATFORMS 3 Conceptual designs and four implentations were considered: Leisure Island Modules: • Visitors Center • Food & Beverage • Accommodation • Nautical Activities & Marina • Safety & Environmental Monitoring • Photovoltaic Plant (large external) • Energy Storage
Green & Blue ‘Crete’ Modules: • Fish Aquaculture • Algae Aquaculture • Processing Plant • Substation • Quick Reaction Maintenance Base (small external) Satellite Units: • Wind + PV + fish cage + algae floater
Green & Blue ‘Taiwan’ Modules: • Fish Aquaculture • Algae Aquaculture • Processing Plant • OTEC plant (small external) Satellite Units: • Submersible fish cage + algae floater
Sustainable Production Concept Potential Modules (various designs): • Bunkering • LNG • Repair Terminal • Security, Surveillance and Anti-Piracy • Container Terminal

W2POWER MULTIUSE PLATFORMS Performance and interactions Validation : -
Test at UCC-BEAUFORT (HMRC) - National Ocean Wave Basin in Cork (Ireland) . April/june 2014
W2POWER BLUE&GREEN CONCEPT Studied initally as one of the case of energy and other uses in FP7 MARINA Platform project (power and fish aquaculture, Norway case) Deeply studied in FP7 TROPOS project for the Mediterranean Sea (near Crete, power, fish and algae production). Synergies with Wind and PV exploitation
Tank testing of platform and fish cage combination at 1:100 scale. Currently at TRL 4 Very good economics and use of the free space and volume available. Up to 120m – 130 m long and 30-35 m deep cages. Up to 40000 m3. 5000 – 7000 Tn/year of fish Potential use of a base port , central semi (TROPOS) or factory ship (freezer trawler) as central processing unit with 20-50 platforms.
Benefits as an Multiuse platform • Significant revenues addition in the same sea space (2050%more), access to cleaner seas for fish farming, lower concentration of fish and their waste (lice and infections risks). • Better economic cycle of the joint investment (CAPEX/OPEX share timing). Sharing of OPEX costs
• Sharing of mooring (floating line and submerge lines ) and very stable access platform offshore. Big space between columns allow for fully assembled cage float in and out • Better access to power for ancilliary services (grid connected). No risk of fuel spilling. • High feedstock storage capacity into the columns. Reduced number of travels.
W2Power for multiuse ❖ Platform designed for Multi-Use from start ▪ Different Hybrid power production: ➢ Wind and wave energy production (grid connected or near offshore consumption
➢ Wind and PV (mainly for the shadow effect for aquaculture ▪ Different energy and aquaculture species and products combinations: ➢ Wind/wave/PV and/or Salmon, seabream/bass, amberjack, meagre, ¿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, surveillance. ➢ Vessel support ➢ …
