Introduction To Industry Scenarios
The core of offshore wind power and offshore platforms is deep-sea high salt spray, strong storm/wave impact, strong corrosion, wide temperature range (-30 ℃~60 ℃), unmanned operation, long-term service (20-30 years), and DNV/ABS/CCS certification requirements.
Typical measuring points:
Offshore wind power:
Tower/foundation: liquid level (preventing seawater backflow), pressure (structural stress), monitoring of marine organism adhesion
Offshore booster station: fire water tank level, pipeline pressure, cooling system level/pressure, transformer oil level
Submarine cable: protect the liquid level and pressure of the pipeline (prevent water ingress)
Offshore platform (oil and gas/multifunctional):
Production compartment: Crude oil/natural gas level, pressure, oil-water interface
Public compartments: fresh water/sewage tank level, fire/compressed air pipe network pressure
Pile leg/conduit frame: liquid level (preventing seawater intrusion), pressure (structural monitoring)
Life module: Drinking water tank, sewage tank liquid level

Addressing Industry Issues
Deep sea high salt spray+strong storm, extremely short instrument life
Ordinary instruments corrode/fail within 1-2 years, frequent replacement requires offshore lifting operations, high cost, and affects service life.
Tower/platform water accumulation+structural stress, high safety risk
Failure to timely discharge water corrodes steel structures and foundation failure; Structural stress monitoring lags behind platform deformation/collapse, resulting in catastrophic losses (in the billions of yuan range).
Strong lightning+long-distance transmission, signal easily interrupted
There are many lightning strikes at sea, long wiring, signal packet loss/interruption, lightning strikes burning instruments, monitoring paralysis, and inability to operate remotely.
Unmanned operation and extremely high cost of manual inspection
Offshore platforms/wind turbines are remote and require boats/tower visits, resulting in low efficiency, high risks, high costs, and lagging data for manual inspection.
Long service life (20-30 years), strict reliability requirements
Ordinary instruments cannot meet long-term stable operation, frequent maintenance affects production capacity, and increases the overall life cycle cost.
