Instrumentation and gas analysis for marine

< return to the range

It is vital for the marine industry to be able to monitor the exhaust gases from their ships in order to comply with international environmental regulations. Different monitoring solutions (gas analyzers, pressure measurement) can prevent marine pollution.

Fuji Electric measuring instruments support marine industry professionals during each phase of ship construction and operation in order to:

  • Reduce operating costs,
  • Increase yields,
  • Extend the service life of installations,
  • Reduce air pollution.

Fuji Electric’s laser gas analyser is capable of measuring and analysing both SO2 and CO2 in seconds. Its high-speed response time amounts to more precise, higher-resolution monitoring than conventional sampling analysers. The analyser determines in real time the state of exhaust gases after washing; thus, it optimizes the SOx scrubber’s pump operation based on alkali content in wash water.
This leads to improved fuel economy and reduced operating costs.

Fuji Electric’s laser gas analyser can be directly installed on the exhaust flue. Its high anti-dust performance guarantees stable analysis and facilitates low maintenance.

As part of the world’s smallest EGCS, Fuji Electric’s laser gas analyser is one-tenth the size of a conventional sampling analyser. Occupying less space gives it a major advantage over conventional sampling analysers and facilitates both retrofitting and installation in new ships.
