Wärtsilä/Hamworthy Inertgas-Generatoren (IGG) sind auf Tankern >20,000 DWT SOLAS-Pflicht. Der IGG verbrennt Fuel Oil in einer Brennkammer, wäscht und kühlt die Abgase und drückt das inerte Gas (ca. 2-4% O2) in die Cargo-Tanks, um eine explosionsfähige Atmosphäre zu verhindern. Wärtsilä/Hamworthy hat geschätzt 30-35% Marktanteil bei IGG-Systemen.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
