THE PROJECT

WIND2GRID aims to promote collaborative research and development integrating technologies, components and systems for innovative offshore substations, based on the development of a floating offshore substation.

Main aims

  • To develop new floating structure concepts valid for multiple locations, including shallow (60-100 m) and deep (around 1000 m) waters.
  • Advanced numerical modelling applied to research into the hydrodynamic behaviour of complex structures and dynamic umbilical cables.
  • Research into the dynamics of the mooring systems of large structures at varying depths.
  • Adaptability to future networks, research into novel power transmission systems (HVAC, HVDC).
  • Research into specific high-performance concrete for marine structures.
  • Research into hybrid coatings for rust-proofing metal components.
  • Implantation of Lean Manufacturing concepts and BIM methodologies for large marine structures.
  • Innovative submarine cable repair systems to reduce O&M costs.
  • Augmented reality and virtual reality concepts to optimise O&M (developing a virtual model of the substation).

WP0. Project coordination

WP LEADER: IDOM

Idom

Participants:

  • All

The purpose of the work package is to ensure the achievement of the technical objectives set and to monitor the progress of the project.

The technical progress of the project will be monitored to ensure the achievement of the objectives and the economic monitoring of the project's development to avoid significant deviations in the budget.

WP1. Design conditions and requirement specification

WP LEADER: IDOM

Idom

Participants:

  • All

The purpose of the first work package is to define the fundamentals of design to be implemented in all work packages.

The fundamentals of design to be defined will enable: (i) addressing the development of different subcomponents; (ii) validating the design; and (iii) implementing it in case studies.

WP2. Conceptual development of floating substation

WP LEADER: NAUTILUS

Nautilus

Participants:

The purpose of this work package is to develop an innovative solution for a floating substation.

  • Based on the design conditions identified in WP1, a comprehensive design will be undertaken, including the floating structure, the topside and the mooring system.
  • The dynamics of interarray and export cables will be analysed to define their design conditions. The development of key ancillary elements, including access and evacuation systems, will be addressed.

WP3. New materials and antidegradation systems

WP LEADER: GALVASALA

Galvasala

Participants:

The purpose of this work package is to analyse new materials for use in offshore structures.

  • It will focus on two types of materials: coatings for the protection against offshore erosion, and new concretes for large offshore structures.
  • In the case of coatings, the goal is the development and validation of a new coating.
  • In parallel, work will be carried out on the development of ultra-high performance concrete in order to increase the resistance of large structures while reducing weight.
  • In both cases, the ultimate goal is cost-reduction of offshore structures.

WP4. Advanced manufacturing and integrated logistics

WP LEADER: NAVACEL

Navacel

Participants:

  • All

The purpose of this work package is to demonstrate the technical and financial viability of floating substation operations to transport topside.

  • It seeks to define the means and procedures needed to manufacture, transport and install a floating substation in each of the phases of development of a construction project.
  • The manufacture, installation and operation of the topside, the floating structure, the mooring, and the cables will condition the design. Such conditions must be identified in the early design stages so that the elements facilitating the operations are included from the beginning.

WP5. Innovations in O&M for offshore substations

The final purpose of this work package is cost-reduction. In this case, it will be achieved through the improvement of different activities related to the operation and maintenance phase:

  • Development and validation of an undersea tool for repairing offshore cables, which would imply a cost reduction in state-of-the-art technology. The goal is to develop a concept tool and a set of manoeuvres that will help reduce the work time.
  • Reduction of installation time lines and provision of greater traceability of the devices installed by means of the development of a real-time management logic platform.
  • Production of a virtual model of a floating substation allowing systems and subsystems to be visualised, so it can be used as tool for maintenance optimisation.

WP6. Dissemination and exploitation of results

WP LEADER: IDOM

Idom

Participants:

  • All

This will contribute to place the Consortium members as well as Basque companies at the technological and industrial forefront of the power sector, both in the Basque Country and internationally.

A plan to exploit the project results will be defined and launched. This plan will focus on technological development, as well as facilitating training for project partners and Basque supply chain participants in the offshore wind power sector.
