Effective as of 1 April 2022, MEPC.1/Circ.864/Rev.1 updates the 2019 guidelines for on-board sampling to verify the sulphur content of fuel oil used on board ships. We have developed a convenient kit to help you comply with the new regulations. Designed for easy installation onto the fuel system of your inert gas generator, it supports sample extraction during operation, and can be easily and safely managed by your vessel crew. Contact us for a quote or for more information on how can we can support you with compliance.

TECHNICAL INFORMATION
SYSTEM DESCRIPTION AND CONFIGURATION
The main purpose of the inert gas production plant is to produce the required quantity of inert gas with the specified oxygen content. The overall inert gas system consists of a combustion air blower, feeding air to the generator where the production of inert gas takes place. The generator has a design capacity as specified, and is automatically operated. In case the produced inert gas capacity is larger than the demand, the system automatically reduce its production.
The main sub-systems for an IGG are:
- Combustion air blowers
- Combustion chamber/scrubber
- Fuel system
- Control system with valves & instruments
- Deck water seal & P/V breaker
Operation and maintenance
- Graphical LCD operator terminal, all major process parameters displayed on the screen
- Combustion chamber and cooling jacket in high performance austenitic stainless steel (ASTM N08904)
- Easy access to burner and combustion chamber by hinged burner front door (no tools required)
- Easy inspection and easy replacement of scrubber components by entering man hole and removable top plate
- Easy installation
- Data communication between panels
Options:
LCD operator terminal functionality

SYSTEM APPLICATION
In accordance with the SOLAS convention, all vessels over 8 DWT carrying hydroncarbon based cargo must supply inert gas to create a non-explosive atmosphere with oxygen below 8%, and establish positive pressure in cargo tanks & deck line. IGG must be operational during all discharges of cargo. To achieve inert gas notation for the vessel, the Inert Gas system must be 125% of cargo pump capacity.
Combustion inert gas systems are commonly used on:
- Product tankers
- Chemical/product tankers
- Offshore vessels like FPSO/FSO's
- S-Max and A-max tankers
- Shuttle tankers
- Petroleum product barges
SYSTEM APPLICATION
Combustible Inert gas systems are used for:
- Primary inert cargo tanks
- Prevent Oxygen from entering cargo tanks
- during discharge
- Purging of tanks
- The Inert gas generator in fresh air mode
- Used to gas free tanks prior to inspection
- Ventilating of tanks

RULES AND REGULATIONS
The Maritime Protection Inert Gas Systems are built in accordance with 1974 SOLAS Convention with latest amendments, and are fulfi lling all of Class, IMO’s guidelines and the demanding conditions of shipboard operation.
|
Protecting small ships with inert gas systems Industry calls for revision to the rules
We’re supporting initiatives within the industry to install inert gas systems on oil and chemical tankers less than 8000dwt. If you are carrying a flammable cargo, then you should have an inert gas system onboard. |
