Our Products

Want to know what clients are saying about us?

Integrating our ROW oil detectors with offshore buoys, we can protect our desalination and power plant from unsuspecting oil spills from passing tankers.

Abu Dhabi, UAE

Desalination Plant

We use the ROW to monitor our water discharge from a sump pit before the water reaches a water treatment plant. Great product and service from LDI.

Antwerp, Belgium

Oil Refinery

The ROW has allowed us to apprehend polluting ships who illegal discharge oily ballast and waste water in our ports. A product worth investing in.

Riga, Latvia

Shipping Port

With ROW stable performance against water level change, flow rate change and foreign objects, while supporting our PLC for integration with our system.

Daejeon, South Korea

Hydroelectric Power Plant

Got questions?

We are focused on providing our clients with the highest
level of quality and excellent customer support.

1. Can ROW be mounted on a buoy or an UAV?

Yes, speak with us today to discuss available options buoy-based ROW.​ For UAV, it can and we are already working with partners on such systems. Sign up to our newsletter to receive updates for availability.

2. Is the ROW able to detect oil in all weather conditions?

Yes. For areas prone to fog, we recommend installing the ROW closer to targets to improve the effectiveness of the device as low cloud coverage scatters the signal to the device.

3. What is the area covered by the field of view?

The field of view of ROW is 0.05 – 0.4 m (Ø), focusing on this size of area allows the device to limit the averaged signal measured from the waters surface to reduce false alarms and increase sensitivity. Because oil spreads rapidly on water, in practice the area of water protected is much larger.
