CAT Targets Cruise for its Multi-Engine Optimizer
Caterpillar is touting its Multi-Engine
Optimizer (MEO) as a solution for ex- isting cruise ships to burn less fuel, run cleaner, keep uptime and reliability high while keeping costs down.
Caterpillar’s MEO is designed to lay over the top of a vessel’s existing power management system, using proprietary performance maps and control algo- rithms to advise the system on which engines to operate and at what load. The second, Asset Intelligence (AI), is a total vessel monitoring solution that collects and analyzes data from onboard systems, then provides recommendations on when and how to take action. Speci? cally Cat contends that MEO and AI can:
