Gas protection motors are explosion-proof combustion engine drives for ships that have to travel in the presence of explosive or flammable gases or vapors.

Gas protection motors are able to suck in air polluted with explosive gases and burn it. Depending on the degree of gas contamination, there is a power reduction, e.g. For example, from around 8,500 kW to around 4,000 kW (per engine) for the North Sea emergency tug that is under construction . For this purpose, the two main engines of this ship are equipped with the appropriate protective devices (sensors, flame arrester , quick-release flaps). The function is checked on a suitably equipped test bench .

Gas protection motors are used in particular in tugs that have to rush to the aid of tankers or gas tankers affected by accidents , as these represent a high potential risk. If the ships are unable to maneuver, the emergency tugs provide a tow connection and prevent further damage or even catastrophes from collisions or stranding .

Examples of such ships in Germany are the multi-purpose ship Neuwerk or the emergency tug Nordic , which has replaced the previous emergency tug Oceanic in the North Sea since January 1, 2011.
