North Sea Boats Built An Armoured Troup Carrier With MAFI Equipment

The X18 ATC (Armoured Troop Carrier) referred to as the "tank boat" is a carbon fibre hulled vessel that can carry 60 troups with a cruising speed of 30 knots.


Powered by twin 1700 hp MTU diesel engines this beast of a boat is capable of a top speed of 50 knots and is highly manouverable and extremely stable.


Designed not just as a support vessel but also as a first line of defence, this incredible  boat is just under 20m in length and runs a jet drive system. It needs only 5 crew for operation and has a range of 600 nautical miles. With a draft of less than a meter it can access area's where more traditional vessels aren't able to operate.


With an operational area of high temperatures and humidity it is important that the massive motors are properly cooled and that the engine room remains free of any salt ingress challenges.

Marine Air Flow's TankBoat Engine Room System Details


For any vessel operating in east Java, protection from the elements is essential to not just the lifespan of the enigne room components but also the safety of the crew.


As with other vessels we have equiped in this area, we chose a two stage air intake system, primarily for its capabilities in larger seas. In conjunction with the double stage grilles which we used on the air intakes, we used single stage grilles for the air outlets.


Stainless steel air dampers and our AC High Volume fans completed the system supplied for the X18.   


Equipment Supplied By MAFI
