PROJECT OVERALL GOAL

1. Develop, build and install research floating platforms to assess wind, wave and otherenvironmental conditions.

2. Develop floating substructures to support current multimegawatt offshore wind turbinesfor 50‐200 m sea depths at a competitive cost


PROJECT ORGANIZATIONPHASE 1:

Theoretical and functional validation. COMBSHORE project funded by CDTI (Finished)

PHASE 2:

Design, construction and installation of experimental floating platforms.

POM project funded by CDTI(Feb. 2009‐ Feb. 2011)

• Scale tests in water tankScale tests in water tank.

• Installation and instrumentation of 2 floating met masts.

• Installation and instrumentation of a 300kWWT on floating platform.

• Constructive, logistic and O&M development for floating offshore WTs.

PHASE 3:

Installation of grid connected multimegawatt floating WT

Consortium: Apia XXI, Instituto Hidráulico de Cantabria (IH), Transportes Lasarte, Erzia, Ecol


•Development of numerical analysis procedure for floating structures based on commercial FEM and

MAJOR ACHIEVEMENTS

Development of numerical analysis procedure for floating structures based on commercial FEM andMBS codes + in‐house developed routines (hydrodynamics)

• In‐house design and construction of experimental water tank for scale models with wave and windloadingg

•Performance of wave loading tests for different floating substructure design alternatives using scalemodelsmodels

•Design, construction and installation of a 100m long floating met‐mast nearby Santander

• Development and installation of a monitoring and communication system

•Design and construction of a 130m long floating met‐mast (current assembly on dock in Santander)
