Power production

ISSUE: Reducing fuel consumption for power production
Auxiliary engines can take up a great deal of energy onboard vessels with large electrical needs. Reefers carrying food and other thermally sensitive cargo are an example of vessels with a high level of electrical needs for operating refrigeration systems. These vessels have energy-intensive mechanisms that require large power production capacity. Fuel consumption for this purpose can be costly if operational efficiency is not maintained between electricity production and usage. Diesel generators need to be monitored and controlled in order to ensure operational efficiency.

SOLUTION: The Marorka Power Plant Module

The Marorka Power Plant Module has the purpose of increasing control and efficiency of electricity production and consumption onboard. It includes monitoring of the electricity producers and consumers (if available) onboard, along with giving important support on the efficient operation of the generator sets. The Power Plant Module is designed to identify how the vessel's auxiliary engines can be run as efficiently as possible.
Power Plant Data Acquisition and Logging is connected to the Power Management System. Extra sensors are added when the necessary measurements are not accessible through the PMS system.
The Module has one main display section (Production), and there is usually one display section for each auxiliary engine (normally DG1, DG2, DG3).
The Production section gives an overview of total electricity production, fuel consumption, and therefore also calculated specific fuel consumption (SFOC). The user is prompted with a message if the diesel generators are not being run in the most efficient manner, and told how they should be run.
