Fuel reduction tool for multi-engine vessels
Caterpillar Marine has introduced a new fuel reduction tool which aims to achieve the lowest possible fuel consumption for multi-engine vessels.
The Multi-Engine Optimizer (MEO) tool works by advising power management systems on which engines to operate by using dynamic asymmetric loads to drive the combination of engines.
“MEO is designed to operate in conjunction with any system, new or retrofit,” said Theodore Wiersema, business process manager for Caterpillar Marine.
“The PLC-based system contains proprietary performance data and control algorithms providing the highest overall fuel efficiency. 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.”
The 700mm 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,” added Mr Wiersema.
By mixing and matching engines and independent load points, he said that 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.
