Auramarine ammonia fuel system
Modular, installation-friendly fuel supply system for engines and other ammonia consumers
Auramarine has 50 years of experience in delivering fuel supply systems for a variety of different fuels. These fuels include marine fuel oils (distillates and heavy residuals), natural gas, biofuels
and methanol. The latest addition to this product offering is our ammonia fuel systems. Why ammonia? If produced in a sustainable way, ammonia can be a zerocarbon fuel and, together with methanol,
a key part of shipping’s energy transition to net zero. This is also what makes it a valuable addition to Auramarine’s green portfolio.
Our primary focus is to deliver a safe,
reliable and high quality fuel supply system. We are, therefore, taking part in ongoing
ammonia research and development projects.
Furthermore, we actively co-operate with
different ammonia experts, ensuring that
we stay at the forefront of industry innovation.
The scope of our delivery is tailored
to our customers’ specific needs
but, as with our methanol systems, we
can provide holistic solutions that cover a
comprehensive
scope of delivery. Auramarine’s
ammonia fuel supply system is suitable
for both two-stroke and fourstroke
engines as well as other consumers. All
safety, design and material requirements
are strictly followed. Dedicated designs are available for both high-and low-pressure
arrangements.

System scope
Auramarine’s most comprehensive scope
includes all necessary equipment from
bunkering through to fuel delivery for
onboard fuel consumers. More specifically:
bunkering units, fuel supply units, master
fuel valve manifold, reliquefying system,
ammonia mitigation system (ARMS), gas
and leak detection, bunkering water safety
system, ammonia control and safety system,
nitrogen generation system, as well
as tank design. Features of some main
components are presented next.
Functions and safety features
Bunkering station
- Leak detection, water safety system and a ship-to-shore link.
Auramarine tank design
- Design for tank connection space (TCS) to C-type tanks.
- Integration allows for compact installation.
Ammonia fuel supply unit
- Actively regulates and maintains the correct fuel pressure
and temperature.
- Measures fuel consumption.
- Filters impurities from liquid ammonia that could damage
the consumer.
Master fuel valve manifold
- Allows for isolating and nitrogen purging of one or
several consumer(s) from the system by utilizing double
block-and-bleed arrangements.
Nitrogen generator
- For purging & inerting of the ammonia system.
Vapour & gas separators
- Separates ammonia vapour from liquid ammonia,
where needed.
- Extraction of nitrogen and other trace gases from the
ammonia system.
Ammonia reliquefying unit
- Reliquefies boil-off gases from the ammonia storage tank
and other vapour sources.
Ammonia release mitigation system (ARMS)
- Featuring controlled combustion, capable of handling
ammonia release from the system.
- Ammonia content measurement.
Ammonia gas detection system
- Detects possible gaseous leaks.
- Alarm levels for personnel protection and explosive
atmosphere prevention.
Automation system
- Control of fuel supply unit and master fuel valve manifold
functions.
- Automatic purging of block-and-bleed valves.
Pilot fuel supply & diesel backup system
- Auramarine can offer pilot fuel supply system and fuel supply
system for the ships first fuel (e.g. bio-diesel).
