Ships have a lot of instrumentation and measuring devices that helps them run smoothly and safely and enabling them to make safe deliveries to the four corners of the globe.
pressure transmitterslevel probes, temperature probes, flow meters, variable speed drives, monitoring screens, analysers gas, all this equipment is essential for the optimal operation of a vessel, whether it's a cargo ship, container ship, tanker, chemical tanker, gas tanker, asphalt tanker, oil tanker, LNG tanker, refrigerated ship, ro-ro ship, bulk carrier, etc.
Fuji Electric offer instrumentation and gas analysis to help shipbuilding professionals and shipboard crews to:
Compliance with current standards
Plant safety
Production quality management
Environmental protection
We understand that our measurement and control instruments are essential to the construction and maintenance of ships. That is why we have made sure that they are robust, durable and easy to install.
Tankers carry oil, chemicals, gas and other liquid products such as bitumen and oil.
Energy groups choose tankers based on how well they perform, how efficient they are, and how much they can hold. The instrumentation on board the vessel is used to make sure that the volume of liquid being transported is optimal and to detect any leaks.
A ship's water tanks are located at the lowest point. A whole system of tanks, circuits and pumps is therefore required to distribute water on board. The same applies to efficient wastewater management.

The ballast tank is a tank of water that helps the ship move better. To adjust the ship, we change the amount of water in the ballast tank. This is called ballasting and deballasting. It's very complex, but it's essential to improve navigation performance. If we deballast in poor conditions, it can cause environmental problems.
Compressed air plays a vital role in many shipboard applications, from starting main and auxiliary engines to handling cargo and regulating control systems. High-pressure air, at 30 bar, is used for a variety of purposes, but mainly for starting the main engine. Reduced-pressure air, at 7 or 8 bar, is used to operate machinery on board ships. However, compressed air leaks represent a major challenge in the marine industry, not only in terms of safety, but also performance and energy efficiency.
Rapid detection and repair of leaks using compressed air flowmeters and pressure transmitters for shipbuilding are essential to maintain adequate pressure in compressed air systems. These measuring devices ensure uninterrupted, efficient operation of essential equipment. Uncontrolled leaks can lead to excessive energy consumption, as compressors have to work harder to maintain the required pressure. This translates into higher operating costs and a larger carbon footprint.
Controlling fuel distribution plays a crucial role in ensuring the constant, optimum performance of marine engines. Precise monitoring of the amount of fuel injected into engines ensures efficient combustion and a significant reduction in fuel consumption. By optimizing fuel consumption, flowmeters help reduce operating costs and the ecological footprint of ships.
Fuel viscosity control is a complementary and essential aspect of the marine industry. Fuel viscosity directly affects combustion efficiency and, consequently, overall engine performance. An accurate viscometer ensures that fuel is maintained at the optimum consistency for efficient combustion, reducing fuel consumption and pollutant emissions. This rigorous control also helps prevent engine problems linked to the use of poor-quality or ill-suited fuels, ensuring greater reliability and longevity of marine engines.
It is important to control and regulate swaying for the safety of loading and unloading operations. Whether they are quay cranes, container cranes, harbor cranes or any other marine cranes, these swaying can be limited by installing a variable speed drive at the input of the electric motor. Braking energy generated by the drive can be fully fed back to the power supply, thus promoting energy savings.
By facilitating compliance with stringent emission regulations, reducing harmful gas discharges, and promoting fuel efficiency, Fuji Electric's laser gas analyser contributes significantly to environmental protection, aligning maritime operations with sustainability goals and ecological preservation.
Fuji Electric's innovative ZQS laser gas analyzer ffor marine exhaust, designed for scrubber and EGCS (Exhaust Gas Cleaning Systems), represents a significant step forward in adherence to MARPOL Annex VI regulations on sulfur emissions, in line with International Maritime Organization(IMO) guidelines. By offering fast, accurate, and real-time analysis of exhaust gases, specifically SO2 and CO2, this technology enables ships to continuously monitor emissions with unparalleled precision.
The laser gas analyser's rapid response time, coupled with its capability to determine exhaust gas conditions after the scrubbing process, empowers optimized control over the SOx scrubber's pump operation. This, in turn, ensures compliance with sulfur emission limits while simultaneously enhancing fuel economy and reducing operational costs. Its compact design, a fraction of the size of conventional analysers, facilitates easy installation, both in retrofitting existing vessels and incorporating into new ships. Moreover, the system's stability, extended maintenance cycles, and resistance to dust accumulation guarantee consistent performance and low upkeep requirements.
For additional gas measurement, Fuji Electric'sanalyser infrared gas ZPA is specifically designed for marine applications. Robust and reliable, it enables precise measurement of gas concentrations such as NO, SO₂, CO₂, CO, CH₄ and O₂, essential for emissions control on board ships. Thanks to its advanced infrared technology, this device guarantees stable performance even under harsh environmental conditions, meeting the stringent requirements of the marine industry.
