Instrumentation and gas analysis for the marine industry

Fuji Electric's measuring instruments support shipbuilding professionals and shipboard crews in :

  • Guaranteeing the reliability and durability of on-board equipment
  • Optimizing storage capacity
  • Facilitate ship navigation, maintenance and operation
  • Securing maritime transport
  • Prevent leaks and protect the environment
  • Improving energy efficiency and ship performance

We understand that our measurement and control instruments are essential to shipbuilding and maintenance, which is why we've made sure they're robust, durable and easy to install.

optimize the storage capacity of the ship's tanks and vats

Optimize the storage capacity of the ship's tanks and vats

Tankers carry oil, chemicals, gas and other liquid products such as bitumen and oil.

Energy companies specializing in the transport of fossil fuels choose their vessels on the basis of performance, efficiency, storage capacity and on-board technology.

monitoring a ship's water system

Monitoring a ship's water system

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.

ballast water pressure detection

Facilitating marine navigation

To correct the ship's list or reduce dunnage, the water level in the ballast tank is adjusted. Ballasting and deballasting operations are highly complex, but are essential to improve sailing performance. Deballasting carried out in poor conditions can pose ecological problems.

Ensuring constant performance of ship engines

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.

control of fuel distribution

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.

Securing and improving the performance of industrial ship cranes

For safe loading and unloading operations, it's important to control and regulate sway or oscillation. Whether for quay cranes, container cranes, harbor cranes or any other marine cranes, these swaying movements can be limited by installing a variable speed drive at the electric motor input. The braking energy generated by the variable speed drive can be entirely fed back to the power supply, thus promoting energy savings.

Analyze exhaust gases from the ship's stacks

By facilitating compliance with stringent emissions regulations, reducing harmful gas discharges and promoting energy efficiency, Fuji Electric's gas laseranalyser makes a significant contribution to environmental protection, aligning marine operations with the goals of sustainable development and environmental preservation.

Fuji Electric's innovativeZQS laser gasanalyser for marine exhaust gases, designed for scrubbers and exhaust gas cleaning systems (EGCS), represents a significant step forward inadherence to MARPOL Annex VI regulations on sulfur emissions, in line with International Maritime Organization(IMO) guidelines. By offering fast, accurate, real-time analysis of exhaust gases, particularly SO2 and CO2, this technology enables ships to continuously monitor emissions with unrivalled precision.

The fast response time of the laser gasanalyser , combined with its ability to determine exhaust gas conditions after the cleaning process, enables optimized control of SOx scrubber pump operation. This ensures compliance with sulfur emission limits, while improving fuel economy and reducing operating costs. Its compact design, a fraction of the size of conventional analysers , facilitates installation, both for retrofitting existing vessels and for incorporation into new ships. What's more, the system's stability, extended maintenance cycles and resistance to dust accumulation guarantee consistent performance and low maintenance requirements.

For additional gas measurement, Fuji Electric'sZPA infrared gasanalyser is specifically designed for marine applications. Robust and reliable, it enables accurate 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.
