Nitrogen generators for vessels and retrofit applications

OXYMAT designs marine nitrogen generators for vessel retrofit projects built around real onboard constraints.

Each project is assessed by OXYMAT in-house specialists, taking vessel layout, purity requirements, available space, compressor setup, piping, control system integration, and other project-specific needs into account. Depending on the application, we work with both PSA and membrane technology to adapt each system to the vessel.

Our approach includes:

Initial vessel assessment and onboard survey
Evaluation of vessel layout, nitrogen demand, available space, existing control systems, and installation conditions before system design begins.

PSA or membrane selection
Technology selection based on required purity, flow, footprint, and operational requirements.

Integration with existing systems
Adaptation of system layouts, piping, compressor setups, and control system interfaces to fit existing onboard infrastructure.

Customized project design
We design and develop systems for both new installations and highly customized vessel retrofit projects with specific layout, control system, and integration requirements.


Gas carriers

Nitrogen systems are used on gas carriers for inerting and controlled atmosphere applications. Systems are designed to integrate with existing onboard setups, with focus on stable supply, space constraints, and operational reliability.

Chemical tankers

Chemical tankers require consistent nitrogen supply for cargo tank inerting and safety. Systems are selected based on purity requirements and adapted to vessel layout, supporting both newbuild and retrofit installations.

DUAL-FUEL VESSELS

Nitrogen is used in dual-fuel systems to support safe operation and controlled environments. Systems are designed to integrate with engine room layouts and existing fuel system configurations.

OXYMAT marine nitrogen generators

Nitrogen onboard is used across multiple operations, from purging to blanketing and cargo handling. Requirements vary, and systems must adapt accordingly.

OXYMAT marine nitrogen generators are designed to handle these shifts in demand. The system allows fast transition between operating modes, supporting both lower and high purity requirements within the same installation.

In addition, dry air can be supplied for cargo ventilation and drying of hold spaces, depending on vessel needs.

Systems are delivered as both standard configurations and engineered solutions, adapted to the vessel, application, and onboard layout.

Applications include

  • Drying of cargo tanks
  • Inerting/purging cargo tanks
  • Padding cargo tanks
  • Pipe purging
  • Super stripping
  • N2 storage (HP)
  • Inerting hull spaces (cofferdams)
  • Gas freeing (dry dock)
