Classified complete solutions for marine engines

Complete classified systems

Complete classified systems with ship controls from Bosch Rexroth and engine technology from Bosch unload engine manufacturers.

Manufacturers of medium-speed and high-speed ship engines can clearly reduce their design and classification workload with complete solutions from the Bosch Group. The optimized Common rail systems, which have been especially designed for operation with heavy fuel oil and diesel fuels, also drastically reduce consumption. This enables engine manufacturers to meet the emission limits which have been set with EPA Tier 4 and IMO 3. The modular ship controls in the Marex product family of Bosch Rexroth cover all types of ships and propulsion systems. All those complete systems are certified by international classification societies which represents an advantage for engine manufacturers.

Until now, engine manufacturers had to coordinate various suppliers for engine technology and ship controls, clarify interface problems on their own, and finally get the results certified by classification societies in a complicated process. With a complete solution from one source, Bosch takes over all these tasks and shortens the time to market for manufacturers. In future, both the common rail system for heavy fuel oil and the maritime common rail system for conventional diesel fuel are planned to function with a higher injection pressure of 2200 bar. This will enable optimized fuel consumption with a reduction in operating costs, and help to fulfill future emission standards. Engine control units adapted for marine applications control the common rail functions and optionally regulate the downstream systems for exhaust gas treatment. Those classified engine solutions round off the ship controls in the Marex product family to an integrated complete system. They communicate digitally with the engine management and fulfill all the specifications for redundancy and safety. Numerous alarm and safety functions ensure the maneuverability in any operation condition. Moreover, the Marex controls monitor the entire powertrain and inform the ship operator about the technical condition of all the critical components. This increases their availability and facilitates the scheduling of maintenance and repairs.

Based on electronic components especially designed for use in maritime applications, Marex controls have proven themselves in ship engineering and have been certified by international classification societies for decades. They consist of a wide range of control elements and visualization tools for the navigation. A modular design makes them ideal for all ship sizes, from yachts to cruise ships. They sensitively control all common ship propulsion systems. This complete solution is suitable for both new builds and replacement of existing controls. In over 80 countries, marine technology experts support engine manufacturers and shipyards in designing and commissioning these complete systems.
