How our nitrogen systems are supporting the green transition
Engines operating on fuels such as LNG, ammonia and methanol require a nitrogen system for safety reasons. For example, for LNG-powered cruise ships, nitrogen will be used to purge the fuel gas system before and after engine start-up, and when maintenance work is carried out to create a safer, more stable environment.

TECHNICAL INFORMATION
SYSTEM DESCRIPTION AND CONFIGURATION
Nitrogen systems typically consist of three major sections – compressor(s), generator, and storage and distribution system. Depending on your application, the nitrogen can be delivered directly to the cargo or void space, or stored in a receiver for later use. A booster compressor can be included to provide nitrogen at higher pressures, filling 200 or 300 bar nitrogen cylinders. Optionally the system can be designed to operate with two different purities simultaneously.
The Maritime Protection nitrogen system uses maritime quality rotary screw compressors to achieve the optimal amount of feed air supply. A choice of compressors are available, based on your preferences and requirements.
The nitrogen generator has an advanced feed air treatment system. Combined with unique functionalities this ensures high quality air, prolonging the lifetime of the membranes. The nitrogen generator separates air into its component gases by passing low pressure compressed air through hollow fibre semi-permeable membranes. By this the air is divided into two streams; nitrogen which holds purity level between 95% and 99,9% and remaining oxygen enriched air which is vented to a safe area.
Rapid system start-up enabling the system to reach purity and dew point quickly and improve operational efficiency. The system has a unique pressure and flow control that automatically adjust the capacity based on the cargo operation.
