Frequently asked questions
What TIDEWATCH does, and what it does not do.
Service
What is TIDEWATCH?
MomentCube’s subsea risk screening service for offshore wind. It computes scour at every foundation and exposure risk along every cable segment from ocean data, adds satellite evidence and ranks where MBES and ROV surveys should go first.
Who is it for?
Wind farm O&M teams, cable owners, survey contractors and teams reviewing new or overseas farms.
Do we need equipment on site?
No. It starts from public satellite and ocean data and runs in a web browser.
Which languages?
The interface switches between Korean and English.
Technology
Can satellites see the seabed?
No. Satellites see the sea surface and what is above it. Scour and exposure are computed from ocean forcing; satellites add indirect evidence such as vessels, structures and sediment plumes. The result is a survey priority, not a survey measurement.
What data do you use?
Copernicus Sentinel-1 and Sentinel-2 L2A, Open-Meteo Marine (waves, currents, tide) and GMRT bathymetry (GEBCO + multibeam). Satellite scenes are found through Element84 Earth Search.
Which engineering formulas?
Soulsby (1997) wave–current bed shear, the Soulsby–Whitehouse critical Shields number, Sumer & Fredsøe (2002) equilibrium scour and time scale, and MPM transport.
How often is it updated?
Ocean data daily, Sentinel-1 every 6–12 days, Sentinel-2 every 5 days on clear days. Re-scan at any time.
Getting started
Can we add our own farm data?
Yes. As-built coordinates, cable routes, foundation type and diameter, grain size, burial depth and past MBES/ROV results all improve accuracy.
Can we stop routine surveys?
No. It narrows the campaign. Keep statutory and insurance surveys for all assets.
How do we start?
Send the farm name, location, number of turbines and foundation type. We build the layout from satellite detection and send a first report.
Are the demo farms customers?
No. The Southwest Sea demonstration farm, Tamra and Horns Rev 1 are seed farms built from public information for pilot calculations.

Tell us the location, number of turbines and foundation type. We build the layout from satellite detection and return a first report with scour per foundation, exposure risk per cable segment and a survey priority list.
