WP3 – Advancement of modelling tools for OWE

Overview

Objectives: To advance existing numerical models (including OWF wake models, ocean–wave–ice models, biogeochemical models and ecosystem models) for evaluating cumulative impacts of OWFs, both for individual OWFs and large-scale OWF groups.

(Lead: FMI / Co-lead: HEREON)

Tasks

The WP3 is divided into five main tasks:

We will further develop the workflow to calculate wind wakes behind OWFs at basin scale using the open-source software pyWake, including verification of these offline wake computations using simulations from the weather model HARMONIE with parameterization of the atmospheric wake effects (at 2.5 km resolution).

The state-of-the-art impact-resolving ocean–wave models will be further advanced for both individual OWF and large-scale applications. For individual OWF, the impacts of turbine foundations on the ocean and waves can be explicitly resolved by the unstructured-grid ocean–wave model SCHISM–WWM (5 m resolution, HEREON). The regional–basin scale models with parameterization of turbine bases (with resolution up to 50 m) will then be calibrated towards SCHISM–WWM high-resolution performance.

We will implement a parameterization for OWF impacts on sea ice in the NEMO–SI3 and ROMS–CICE model systems, using regional setups in the north-eastern and southern Baltic Sea on a sub-kilometer-scale resolution. We will also assess the footprint of wind turbines by employing a Lagrangian model to simulate the trace from each wind turbine in a drifting ice field.

With inputs from models developed in T3.2–T3.3, we will adapt existing impact-modelling tools to assess OWF impacts on: (i) Fouling including multi-use sites (dedicated to low-trophic aquaculture) (SCHISM–WAM–ECOSMO; MAR–PHY–BGC); (ii) The spatial ecological connectivity of key species and the potential for OWFs to serve as stepping stones for non-native species by estimating species dispersal pathways using OpenDrift; (iii) Water quality, productivity and organic/mineral particle exports using ROMS–ERSEM; (iv) Water quality and optimal habitat of four commercially fished species (CEMBS–ECOFISH).

Models developed in T3.1–T3.3 will be tuned and calibrated against observations (from WP2) to achieve improved performance for targeted sub-regions. In selected sub-regions, we will demonstrate further reduction in model uncertainties by assimilating: (i) Satellite-derived water quality variables; (ii) Ocean and ecosystem data, including OWF and aqua-farms. In all cases, the 2010–2020 period will be used for calibration and validation.
