Best in Class Commercial Grade Optimization for Diesel Electric Pleasure Craft

Miami, Florida – Caterpillar Marine is pleased to introduce the new Multi-Engine Optimizer (MEO) tool into the yachting market. MEO leverages proprietary performance data and patented control algorithms to provide intelligence for power management systems. MEO works by advising power management systems on which engines to operate and enables the use of dynamic asymmetric loads to drive the combination of engines and loads to create the lowest possible fuel consumption.

“MEO is designed to operate in conjunction with any system, new or retrofit,” said Theodore Wiersema, product manager for Caterpillar Marine. “The PLC-based system contains proprietary performance data and control algorithms providing the highest overall fuel efficiency or NOX reduction. MEO enables a stable bus while engines of different size and rated speeds simultaneously share load operating at different targeted fuel set points. The cost savings can be quite significant depending on the load profile of vessel and the types of engines on the bus,” said Wiersema. 

“It is our opinion that it is impossible to more efficiently utilize your engines then through the efficiency offered by MEO. Our proprietary performance maps and control algorithms provide precise control to the exact combination of engines and load points that drive the lowest fuel consumption or lowest NOX production,” said Wiersema.

The 700cm wide MEO cabinet can be installed in an engine or control room and requires less than six wire connections. “MEO is viewed by marine societies as an advisory system and will have type approval certification. As an advisory system MEO can be turned off at any time allowing the existing power management device to return to its normal operating procedures to provide an extra layer of protection and safety,” said Wiersema.

By mixing and matching engines and independent load points, MEO allows engines to provide power at their most efficient point. Compared to the common scenario of engines operating at an equally shared load the MEO system creates an unlimited combination of virtual engine rooms to match each particular vessel load.

MEO is now available for purchase and is backed by the worldwide Cat® dealer network with trained technicians to ensure service support is never out of reach. To learn more about MEO and meet the Caterpillar marine experts, stop by the Caterpillar exhibit #F407 at the Miami International Boat Show, or at the Miami Yacht Show on Collins Avenue at exhibit C-13/CC35-37. Both shows will be held February 15 – 19, 2018 in Miami, Florida.

What if you could create one big, customized virtual engine out of your individual off-the-shelf engines?

The days of having four or six identical engines always operating at an equally shared load could be over. Because Cat® MEO gives you the flexibility to have any combination of small, medium, and large diesel-electric and mechanical-hybrid engines and batteries all operating at independent load points – creating one big virtual engine that is customized to each vessel.
