Inert Gas Generator (Tanker) · Boilers
The system generates a low-oxygen inert gas stream and supplies it to cargo tanks or associated spaces so the atmosphere is kept outside the flammable range during approved cargo operations. A typical IGG installation includes a combustion or gas-generation section, gas cooling and cleaning equipment, blowers, oxygen monitoring, pressure control, valves and safety interlocks. It is integrated with the cargo-tank inert-gas main and with deck isolation, non-return and pressure-protection arrangements required by the vessel design. Reliable oxygen measurement and correct gas pressure are essential because the system is a safety barrier against formation of a flammable cargo-tank atmosphere. The exact burner arrangement, gas capacity, oxygen limit and control settings are vessel-specific; refer to the manufacturer documentation and applicable statutory documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Function-test oxygen monitoring, high-oxygen shutdown or diversion, gas-temperature protection, blowers, combustion safeguards and deck isolation arrangements. Inspect scrubber/cooling sections, drains, demisters, fans, dampers and gas piping for deposits, corrosion and leakage. Verify the deck water seal or other approved non-return arrangements where fitted and inspect pressure/vacuum protection associated with the inert-gas main. All oxygen limits, test values and statutory checks must follow the approved vessel and manufacturer documentation.
Carry burner and ignition service parts, flame-detection components, blower bearings/seals as appropriate, oxygen-analyser cells and sampling components, valve-actuator kits, pressure/temperature sensors, scrubber nozzles or demister parts where replaceable, gaskets and control fuses. Critical spares should be aligned with cargo-operation risk and the vessel's redundancy philosophy.
