China continues to lead the global wind energy market. In 2016, more than 23 GW of wind power were installed and with the increasing number of offshore wind projects on the agenda in the East China Sea, we now offer our clients operating in these areas, a full metocean forecasting system.

East China Sea

ConWX Metocean Forecasts for East China Sea uses market’s best and most accurate weather models. The system provides detailed data for all metocean parameters, so you can you can plan and operate you offshore project, confidently and safely.

Winter is here and the season of high wind production. Is your wind park at peak conditions and ready for it? Want to know the best time for service and maintenance to benefit from high wind production? The solution is a solid O&M system!

This is especially needed for today’s large wind farms where production rates can differ up to 100% within a park. These production differences are mainly caused by shadow and wake effects.

Shadow effects are highest in wind speeds between 6 and 12 m/s with significant production differences on the front and end rows in the farm. ConWX offers a full O&M system that forecasts production for the individual turbine and/or sectors in the park.


In that way, you will know which turbines are most suited for maintenance and avoid those with the highest production on that specific day.  Any wake or lee effect due to wind direction and atmospheric stability related changes are recognised and forecasted. Like seasonal changes such as sea breezes are adapted into the systems’ knowledge and algorithms.

With ConWX O&M system you get:

  • Production forecasts on turbine and sector level.
  • Forecasts on wake and shadow effect
  • Up to 8 daily updates
  • Forecasts 156 hours in advance
  • 99.7% system uptime
  • Web site presentation
  • 24/7 customised service

raw weather data

With experience from countless wind power projects all over the world, ConWX has the data you need to carry out successful wind site assessments. ConWX Hindcast Data has proven best in test several times and we compare our data towards actuals on a regular basis, to ensure our customers are provided with the most accurate data.

Our hindcast data can be acquired for single points, entire grids, covering entire Europe, USA, India, China, Taiwan and Japan. Likewise, we can provide data in different resolutions and time series lengths, all tailored to your specific needs and requirements.

At ConWX, we have recently carried out a new comprehensive metocean study of the Arabian Gulf, based on hindcast of a continuous 30 year period (1986-2015) and 200+ storm events.

The hindcast data are ConWX mesoscale-modeled data generated from historical global analysis field models. The models used are the IRIE weather model, Wavewatch III, version 3.14 wave model, and GETM current model. All models have been re-calculated 30 years back with a spatial resolution of 3-10km using boundary input from the global model ERA/ECMWF.

The Weather and Wave Models are based on complex physical equations of fluid dynamics and thermodynamics and use current weather conditions as first input to mathematical computer programs.

ConWX Arabian Gulf MetOcean Hindcast utilizes hindcast models of higher resolution and more powerful physics than the previous studies for the Gulf region (e.g. PERGOS). In contrast to existing climate data for the Arabian Gulf, ConWX hindcasts are of most recent date and for a longer continuous period.


ConWX Arabian Gulf MetOcean Hindcast Deliverables include:

  • Extreme values for wind speed, wave height, water level, and ocean currents
  • Hindcast data expressed with annual, monthly, and hourly frequency in tables
  • Time series of weather, waves and ocean currents for +200 storm events for the 30 year period 1986-2015.

ConWX are proud to announce that we have developed a brand new logistics tool to use in connection with development and maintenance of offshore wind parks. We have named the new system “ConWX Metocean Logistics Tool” as it enables you to plan single or sequenced offshore operations.

The actual system is an advanced simulation tool that uses high-resolution meso-scale hindcast data from weather, wave and current models to calculate the expected waiting on weather (WoW) for an offshore operation or a combined series of operations. The module includes data for a long list of parameters, making it easy and cost-effective for you to use.

With this new planning-tool, the user is able to define weather parameters and threshold values, relevant for craning, jack-up and mobilisation etc. in one and same system. Once these data are provided, the system calculates operation duration and the expected WoW on monthly basis with percentile likelihoods.

Within minutes, the system then generates a PDF-report and a graphical presentation that is send on e-mail, making it easy for you to adjust or re-calculate operational scenarios. The offshore operations are simulated using a 15-year metocean time series in hourly resolution, which provides a solid base for statistics generation.

You as offshore planner is thereby provided with a highly accurate picture of the expected duration of offshore projects as well as the associated waiting on weather risks, helping you save time and operational costs.

ConWX Metocean Logistics tool is available as a module in the Online Forecast and Hindcast System.

Please contact us for a live demonstration of the new logistics system.
