marine grid survey
The modern world fleet is today equipped with frequency converters, computers, LED lighting, UPS etc. These products may reduce the energy consumption, however they come with several downsides.
They all create current harmonics; this is especially important to know about and handle on a vessel since it is an island grid with generators operating as a soft and sensitive grid.
PERFECT GRID QUALITY
The perfect power has a power factor of 1 where the current is in phase with the voltage for each phase. The phase voltage is phase shifted 120° without any unbalance. The voltage and current are sine wave.
The perfect power quality does not exist, however we can identify the non-ideal characteristics and come with improvements.
POOR GRID QUALITY
There are many known problems to poor marine power quality like:
Unwanted tripping of breakers
Shorter lifetime of equipment
Non-compliant class requirement
GOOD GRID QUALITY
The benefits of an improved marine power grid are:
Less problems and off-hire
Longer lifetime of equipment
Less fuel consumption
OUR MARINE GRID SURVEY
STADT can support with a marine grid survey where we come onboard your ship for a power quality measurement.
Our marine grid survey will include:
Pre-study of the grid
Grid Quality Report
Suggestion for improvements
