The new Kongsberg Maritime MetaPower® torque & power monitoring system,
facilitates cost-effective operation by providing vital data to enable a vessel
to maintain or increase speed while saving significant amounts of fuel, and reducing
CO2 and NOx emissions. As a vital application for optical engine operation, MetaPower®
is part of Kongsberg Maritime's growing Green Ship product portfolio.
Improved fuel and emissions performance
MetaPower® provides improved fuel and emissions performance by measuring
torque and power transferred from the main engines to the propellers. It also helps
to reduce maintenance and extend engine life, by comparing the power output and
fuel consumption, which provides valuable information that can be used to avoid
over-stressing the engine.
MetaPower® measures torque through patented IR laser technology, providing
several benefits over conventional torque measuring systems. Because it does not
require sensitive electronics (strain gauges) glued to the shaft it suffers no mechanical
wear, no zero point drifting over time and is not affected by ambient temperature
changes or centrifugal forces. This means that maintenance of the system can be
carried out by the crew in just minutes. It is also easy to re-install after stern-tube
A key part of the system is the MetaPower® Torsional Oscillation Analysis
Software (TOA). TOA is a tool for recording, measuring and analysing variations
in torque, which enables cost and time saving preventive maintenance planning and
corrective actions. TOA software makes it easy to detect operational disturbances
in an engine by showing differences in rotation frequency on a sound engine against
that of an engine misfiring on one of its cylinders.
MetaPower® can be delivered as a standalone installation, or integrated
with the K-Chief automation or AutoChief propulsion control system. AutoChief
also integrates the AVL engine performance and optimization system (AVL EPOS™) as
well as other performance monitoring sensors, providing a complete solution for
engine monitoring that supports the Green Ship concept.
