Marine & Offshore Transformer DGA Monitoring — Salt-Fog, Vibration, Remote

The Most Demanding Environment

Offshore platforms combine every challenge: salt-laden atmosphere causing accelerated corrosion, continuous low-frequency vibration, limited access (quarterly at best), and the highest service visit cost in the industry — $2,000–8,000 per technician trip.

Offshore Wind Substations

Offshore wind GSU transformers face salt fog (ISO 12944 C5-M), 0–100% daily load cycles accelerating thermal aging 3–5×, and limited weather-dependent access. The DGA-200 with LoRa wireless transmits up to 10 km to the platform communication mast — no cable pulls required. Read the offshore wind case study →

FPSO & Marine Vessels

Permanent inclination (15° list), corrosive atmosphere, and space constraints. Classification society compliance: DNV-ST-0145, DNV-CG-0339, ABS Steel Vessel Rules Part 4, Lloyd’s Register Part 6 Chapter 2.

Wireless: The Offshore Imperative

Running a single RS-485 cable across an offshore platform costs $5,000–15,000. LoRa eliminates this — one gateway serves up to 100 monitors. For unmanned platforms, the optional 4G LTE module transmits directly to shore.
