LNG FGSS and Bunkering System:

Zicom studies each vessel unique chartering needs and configure our modular system to suit your operational requirements. We provide system solution for low-pressure(LP), high-pressure(HP) and Dual Fuel gas engines and augmented with matching boil off gas(BOG) management solutions.

The BOG management solutions can be a Low Pressure Compressor system where BOG is being conditioned for auxiliary engines and consumables. We can also provide a much more efficient and flexible High Pressure Compressor system(Patent) where BOG is conditioned for use in either high pressure gas engine and low pressure auxiliary engines and boilers. We partner with established maritime research institutes and classification societies for research, development, validation and fine-tuning of our system.

Our scope of supply includes:

  1. System Design and Analysis
  2. Bunkering System and Storage Tanks
  3. Fuel gas preparation system including HP/LP fuel pumps, HP/LP BOG compressors, Water/Water-glycol system
  4. FGSS controls system, including shipshore link, Emergency Shutdown, BOG management, Gas detection.


We offer solutions catering for the operational needs of different vessel profile. These ranges from larger vessels with a longer sailing time as well as smaller compact harbour crafts, offshore support vessels.

Tankers, Bulk Carriers, Container Vessels
Long Voyage and Route Flexibility requiring efficient High Pressure FGSS with Active Boil Off Gas Handling System
AHTS, Tugs, Crew Boats, LCT
Dedicated operational profile with compact and simple Low Pressure  FGSS


Competitor’s LNG FGSS limitations for vessels requiring longer sailing times:

In response, ZICOM Innovative Design allows BOG to be fed to MEGI together with HP-Pump. This allows BOG to be consumed during sailing by the MEGI. Tank can always be kept at low pressure ensuring a cold LNG in all conditions


Our System Advantages:


1 – With just one compressor the tank can be constantly kept at very low pressure of  ~1barg. This ensures that the LNG inside the tank is as well at a low temperature of ~ -150oC
2 – Allows easy BOG management by consuming BOG in MEGI thus providing full flexibility during sailing
3 – The system can be used for all kinds of vessels with any tank size and smaller LP-consumers
4 – Tank pressure can be kept very low thus keeping the LNG at low temperature and the tank cooler
5 – Superior control system implementation requires no LNG recirculation to tank
6 – Utilisation of just a peak-shaving valve ensures minimum gas recycling back to tank during MEGI load change
7 – Bunkering time cut-down significantly due to tanks arriving at a convenient conditions. Less BOG production during bunkering and hence no wastage
