What sort of radar do I need to be able to make use of Seaview Realtime software?

You will need a High Frequency (HF) phased array radar.

What is the difference between a phased array radar and a compact antennae?

Although compact antennas are much easier to install there are questions over how accurate and reliable the data provision is, particularly for good wave data. Seaview Realtime provides customers with surface-wave, wind and current and for this reason works with phased array radars. Our closest radar partners are Helzel and Neptune although if you have a different phased array HF radar we should also be able to work with this.

I already have a HF radar, how many channels (i.e., antennas in my phased array) do I need to be able to use Seaview Realtime software?

The more channels you have the better. The software itself does not need to know the size of your array but it works best with 12 channels and above. We advise a minimum of 16 to minimise antenna sidelobe influences which can reduce the accuracy of wave measurements.

Can I see some examples of your wave data?

Data is often sensitive to the purchasing client. Clients who are happy to share their data do so on our website www.seaviewsensing.com.

Where else do you have deployments?

We have installations all over the world including the UK, France, Oman, Australia and the US. Our website shows further details of our deployments: www.seaviewsensing.com.

My project is not long term, is there a problem in moving my radar to another location once it is finished?

In theory, there shouldn't be a problem although you will probably need help at your second location for reinstallation. Roving software licenses are available for this situation.

What are the benefits of using Seaview Realtime instead of wave buoys, current meters or other in situ instrumentation?

Seaview Realtime software is not in direct competition with wave buoys or current meters. And, in fact in some cases we work in addition to in situ instruments. The difference between our measurements and those of a wave buoy or current meter is that we are land based and are not at risk to fishing or shipping hazards. Also, our software provides measurements at many different locations across the radar field of view. Generally, wave buoys do not measure surface current or wind, whereas Seaview provides this information simultaneously with the wave measurements. Seaview software possibly has a higher set-up cost, the maintenance costs are significantly lower over the long term.

How much does the Seaview Realtime software cost?

It really depends on the particular project but as a guide the software usually costs a tenth of the cost of the radar.

I don't know what the best solution is for me, is there anyone that can help me and point me in the right direction?

Our company founder, Prof. Lucy Wyatt, is available to work on a consultancy basis. Lucy acts as an impartial advisor.

Is the software affected by offshore rigs and wind farms?

Offshore wind farms do make it difficult to measure waves close to the turbine locations when they are in operation. Current measurement does not appear to be affected. Offshore rigs do not affect the data.

What are the main benefits of using Seaview Realtime software?

Seaview Realtime software provides full directional spectra data, measuring waves (as well as currents and winds) across a field and not at one particular location.

As the radar system is located onshore, the equipment is easy to service and maintain, is not at risk to shipping or fishing equipment and provides a good long-term data solution.

Gaining concurrent, long term wave, wind and current data over a large area may help not only in feasibility studies and system design, but may also allow refinement of the application specification and aid installation, so reducing costs.

The met-ocean data may also be used in the operation of the equipment, for example, providing long-range real-time data may allow precautions to be taken as storms are measured, approaching the generators.

How will I receive the data?

You can monitor and download the data on our dataviewer via the internet. Files with directional spectra (these cannot be downloaded directly for the dataviewer) and/or specific parameters can be delivered automatically to you via FTP.

Can the software be used for forecasting?

The software cannot strictly be used for forecasting. However, the long term historical data can be utilised for prediction purposes.
