The GASPOC project delivers its value through both new products and services as well as through new data, features and functionalities inside well-established products and services to allow an immediate impact via known market pathways. GASPOC thus contributes to or delivers the following list of products and services:
High-quality and realiable metocean data is fundamental to the success of any marine project.
You can save time gathering, analysing and reporting metocean data with DHI’s Metocean Data Portal.
The global portal enables you to download and validate 40 years of wind, wave, water level and current data, as well as retrieve interactive analytics or download time series data through a user-friendly interface or API.
With the subscription based service, improved efficiency is experienced across all stages of your offshore or coastal project—from feasibility, planning and design, to construction and operation.
GASPOC contribution:
Planned for August 2022: A new high resolution accurate Global Wave Model dataset covering 43 historical years 1979-2021.
Planned for March 2023: Automated access to your private Fast Wave and Fast Flow model results and auto reporting functionality
With MIKE 21 Spectral Waves, you can calculate wind-waves in all seas – easily and accurately.
The numerical model can calculate the size of wind-generated waves and swell to produce metocean data as a solid and cost-effective foundation for a multitude of offshore or nearshore wave sensitive engineering activities, e.g. Offshore Wind Energy activities.
This advanced 3rd generation wind-wave modelling software offers a pioneering flexible mesh approach and highly efficient engine parallelisation.
MIKE 21 Spectral Waves enables you to properly resolve the physical environment and governing wave processes by calculating wave climates at the regional and local scale when high spatial resolution is required.
GASPOC contribution:
Released 24 November 2021: Research based new Source term formulations we well as input correction to neutral wind speed included in Release 2022.
These are a prerequisite for the accurate new long term Global Wave Model data sets and the wave siting data in the Global Wind Atlas.
Short description: ModelSkill is designed to be your modelling validation assistant. It should be useful enough to use every time you do a metocean simulation. Modelskill will make it easy to assess the skill of a metocean model by comparing model results with measurements also when result is split on several files (2d, 3d, yearly, …), to compare the skill of different calibration runs, to compare your model with other models, to use a wide range of common evaluation metrics, to create common plots such as time series, scatter and taylor diagrams, to do aggregations. And it should be difficult to make mistakes by verifying input, trustworthy by having >95% test coverage and easy to install.
GASPOC contribution:
During 2021 and H1 2022: Support for efficient comparison against satellite altimetry data via aggregation in spatial bins and improved scatter plot including data density visualization.
MIKE Metocean Simulator is a GASPOC initiated new data and application driven metocean downscaled wave modelling workflow. It transfers regional scale modelling results from the Metocean Data Portal (MOOD) to the local scale of offshore wind farms, access and cable corridors as well as ports and thus generates new project specific data sets in the data portal.
PyWake is an open-sourced and Python-based wind farm simulation tool developed at DTU capable of computing flow fields, power production of individual turbines as well as the Annual Energy Production (AEP) of a wind farm. The software solution provides an interface to both a selection different engineering models as well as CDF RANS (PyWakeEllipSys). It is highly efficient in calculating how the wake propagates within a wind farm and can quantify the interaction between turbines. The main objective of PyWake is to calculate the wake interaction in a wind farm in a computationally inexpensive way for a range of steady state conditions. It is very useful for computing the power production of a wind farm while considering the wake losses for a specific wind farm layout configuration.
GASPOC enhanced the technical merge of PyWake function and GWA data, including the interface, data transmission from GWA to PyWake, test PyWake function with the new input. The input data include wind speed and turbulence intensity at given heights.
PyWAsP is a powerful software tool that allows users to easily access the functionality of WAsP, the leading tool for predicting wind resources of wind turbines in different terrain. With PyWAsP, users can easily integrate WAsP’s powerful wind resource prediction capabilities into their own Python-based applications and projects. This allows users to take advantage of the advanced wind resource prediction capabilities of WAsP without needing to learn the intricacies of the WAsP tool itself. So, whether you are a professional wind energy consultant, a researcher in the field of renewable energy, or simply someone interested in wind resource prediction, PyWAsP has something to offer. With its intuitive Python-based API and comprehensive documentation, PyWAsP makes it easy for users to get up and running quickly and start using WAsP’s powerful capabilities to their full potential.
GASPOC enhances the PyWAsP function in receiving data from Global Wind Atlas (GWA), including siting parameters. GASPOC enriches the GWA with global ensemble data for the extreme winds and turbulence data in the coastal and offshore area, at 10 m, 50 m, 150 m, 200 m and 250 m.
Convenient near real-time marine altimetry satellite data for modelers.
Near real-time global sea surface height, wave height and wind speed data, conveniently packaged for hydrodynamic modeling.
Brief description: This portal hosts many global data layers for wind energy applications, including wind resource data and siting parameters at several heights relevant for modern wind turbines, see the figure-(a) below and the drop-down list. Before GASPOC, the data cover all land area and coastal zones (200 km offshore from shoreline), at a spatial resolution of 275 m.
GASPOC contribution: GASPOC adds data layers over all water area, including particularly the 50-year wind and turbulence intensity. The 50-year winds are calculated using the spectral correction method based on several reanalysis products: CFSR, MERRA2 and ERA5. Within GASPOC, the spectral correction method for TC-affected areas has been further developed by generalizing the calibration methodology to MERRA2 and ERA5 as well as a spatial expansion of the TC-affected zones based on long-term best track data. See the figure-(b) below. The turbulence intensity is calculated using ERA5 data with turbulence considering 2D turbulence, sea state and stability effect.
Short Description: The Vento Maritime Offshore Weather Service is a web service that provides metocean data analytics that tailormade for planning any marine operation in connection with planning of installation, operation, and maintenance of an offshore windfarm. The standard setup make use of global ERA5 hindcast data and HYCOM surface current reanalysis data. However, if the customer prefers metocean hindcast from even higher quality regional or local model setups this can be included. Furthermore, if the customer has measurement data this can be included to make a validation of the hindcast data and therefore provide vital quality measure of the hindcast data and the analytics calculated. Additionally, a ramp up / ramp down analy-sis will be carried out to validate the calculated weather windows. This analysis will also provide a quality as-sessment of how well the hindcast model will perform when forecasting during project execution.
GASPOC contribution: GASPOC provides access to spectrally corrected, global hindcast data for even higher accuracy in the calculated metocean statistics. Furthermore, it provides the possibility to utilize downscaled very high-resolution local wave model setup. This is crucial for customers planning near-shore marine operations, where coarser global hindcast models will not suffice.
Vento Maritime Offshore Weather Service provide tailor-made consultancy related to marine weather and ocean environment.
We can answer the following questions for you:
Customized forecast, hindcast and advice to marine projects are offered along with specialized risk analysis reports. A MetOcean consultancy report will be tailored to your individual requirements, focusing on the parameters that are most important, so that you can confidently plan structural designs or marine operations and thus reduce expensive operational down-time.
