Why ROV System Needs Static Frequency Converter
As a electric engineer, i have many years experience in power automation systems, I randomly see the common challenge, that is operation of Remotely Operated Vehicle (ROV): the power source. ROV and its delicate control systems—including motors, sensors, manipulator arms, and cameras—are often manufactured for a specific power standard, say 60Hz. However, the vessel’s power supply might be 50Hz, or vice-versa. This frequency disparity is not a simple inconvenience, but a threat to your entire operation.
Why a Static Frequency Converter is a need for ROVs:
Precision Motor Control: ROVs use AC motors. The motor’s operation frequency would be different from the incoming power frequency, imagine an different frequency on running may leads to damage to ROVs for a long-term run. A static frequency converter provides a solid output frequency (e.g., an ideal 60Hz from 50Hz input), ensuring precise and predetermined AC power to motor operation.
Protecting Sensitive Avionics: The voltage sags, harmonics, and frequency fluctuations from a poor power solution can cause data corruption, system resets, or even permanent damage. Our frequency converters provide a regulated pure sine wave output with low Total Harmonic Distortion (THD), creating a pure and clean environment for electronics.
Operational Flexibility & Safety: A vessel or offshore platform with a right static frequency converter is the key to succeed. Having a sufficient power rating is mandatory when sizing frequency converter, the safest way is to keep the sum of the ROV nameplate ratings below 60% of the converter’s kVA rating.
The Engineering Behind the Solution:
The converters we designed for these applications go beyond simple frequency conversion:
Ultra-fast transient response to handle the start-up/inrush current when motors start-up.
AC filtering to ensure compatibility with sensitive marine communication and navigation systems.
Marine type construction (corrosion-resistant) to withstand the harsh offshore environment.
In the high-stakes of marine operations, where an ROV downtime can cost tens of thousands per hour, a reliable static frequency converter isn’t just an electric equipment—it’s your primary assurance for a successful, safe, and efficient mission.
