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 transmits over a single RS-485 run to the platform communication mast. Offshore wind DGA monitoring →

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.

Communications Offshore

Each monitor reports over RS-485 / Modbus RTU to the platform communication mast, which carries the data to shore.
