SEA CHEST INLET
The sea chest inlet design is optimized and tailor-made for each system. During the design stage, we study the risk of cavitation and the wake occurrence. A well-designed system is cavitation free, which reduces noise and vibration, and generates a minimal wake which does not interfere with propeller and water jet efficiency..
EXHAUST OUTLET
The exhaust design follows a one-design principle, similar to the sea chest, where each outlet is designed for your particular vessel, engine and speed range.
It is important to keep correct back pressure in the exhaust in order for the engine to work properly. Our experience and knowledge enables us to optimize the outlet to obtain an optimal back pressure. The result is verified through a CFD analysis. Furthermore, a small interceptor is often designed in front of the outlet in order to receive a constant flow of gases, which reduces pulsations and thereby reduces noise and vibrations.
