MarineDiesel engines are the lightest, and most compact, of any engine on the market in our class. That is indisputable fact.
Why does this matter?
Quite simply, MarineDiesel engines can fit into tight places that simply do not have the space for our larger competitors. On boats, especially RHIBs or small high speed craft, this is a very important product feature. RHIBs, in particular often have tiny engine compartments located immediately under the deck, with little excess room. The vessel pictured above is a recreational vessel with three engines. Engines made by our competitors would not only never fit in the limited space, but their extra weight would shift the LCG of the vessel considerably.
With catamarans or trimarans, a different problem emerges. The beam on each hull. Port or starbord, engine compartments are narrow, with little extra room.
This can be an issue in industrial applications, too. Our MDPT subsidiary is currently involved in a re-powering project involving armored vehicles. These vehicles are designed with precisely zero excess space, and the smaller, lighter MDPT engines make a big difference in vehicle performance and ease of operation.
In fact, the biggest problem we face in these cramped quarters is providing adequate cooling for the engines, whether on land or at sea. Engines produce a lot of heat, and that heat must be dissipated. Through years of experience, MarineDiesel has learned practices and techniques that provide adequate cooling, such as louver design, blowers, and engine placement.
