Automated Monitoring of Sea Conditions for Better Results

Subsea Structure Use Cases 

The HydroFi Modem – Wind Energy and HydroFi Modem- Oil&Gas are ideal for subsea applications common to the operations and construction of wind farms, oil and gas pipelines and structures, and port and harbor infrastructures. The HyFi Modem is connected to the preferred sensor and fixed to the side of a submerged structure at a depth of between 5-10m but can scale up to 30m with the use of the larger CSignum antenna. The receiver is then fixed to the same structure above the waterline to connect to either a shore network, SATCOM or cellular device for onward data transmission.

Subsea Structures – Use Cases

Structural Asset Health

Using the HydroFi Modems, operators can frequently and automatically measure pressure, flow, pollution, corrosion, strain, motion and fatigue as well as receive early alerts regarding the health and remaining life of their subsea structures without the cost and risk of sending teams of divers out for visual inspections.

Subsea Structures – Use Cases

Construction and Decommissioning

Using HyFi Modems, operators can monitor structure stress in real time and protect the safety of their crews as they build and decommission platforms, and monitor water quality during dredging operations to ensure there are no ill effects on surrounding environments.

Subsea Structures – Use Cases

Going Wireless in Adverse Environments

HydroFi wireless modems enable operators to cost-effectively fit systems into adverse environments which historically have resulted in cable failures and high maintenance costs. By using HyFi Modems, operators can automatically receive transmitted data in real-time rather than relying on infrequent, expensive and dangerous in-person visits to collect data.

Benefits

  • Only Transmission Across Water-Air Boundary Adds Flexibility

    CSignum technology integrates with most standard sensors to work with what you already have and is the only solution that can transmit digital data through the seabed, structures, water column and across the water-air boundary, so operators can automate and reliably send sensor data subsea, sea-to-air or air-to-sea, wherever they need to place modems and receivers above, on or below the water.
