Marine vessels, offshore platforms, and shipyards operate with complex electrical systems under demanding environmental conditions. Propulsion drives, welding machines, cranes, shore power systems, pumps, radar, navigation, and communication equipment may cause harmonics, reactive power fluctuation, voltage drops, and electromagnetic interference.

CNBYG provides reliable APF and SVG power quality solutions for Marine & Shipbuilding applications, helping customers improve power stability, protect critical equipment, and ensure safer electrical operation.

Solution Overview

Marine and shipbuilding electrical systems often include both sensitive equipment and high-power dynamic loads. On vessels and offshore platforms, propulsion systems, variable-frequency drives, pumps, and navigation systems require reliable power. In shipyards, welding equipment, cranes, heavy machinery, and shore power systems may create severe power quality problems.

CNBYG’s APF and SVG solutions are designed to improve electrical stability in marine and shipbuilding environments. The APF mitigates harmonics generated by power electronic devices, while the SVG dynamically compensates reactive power caused by motor loads, welding equipment, cranes, and shore power operation.

The system can be customized with compact cabinet design, enhanced protection, ventilation, communication, and installation options.

Customer Challenges

• Propulsion drives and high-power motor systems generate harmonics.
• Welding equipment and cranes cause reactive power shocks and voltage fluctuation.
• Harmonics may interfere with navigation, radar, communication, and automation systems.
• Limited electrical room space requires compact equipment design.
• Humidity, salt mist, vibration, and dust require higher equipment reliability.
• Shore power connection and load switching may affect voltage and power factor.
• Continuous operation requires stable and maintainable power quality equipment.

CNBYG Solution

CNBYG provides customized power quality solutions based on APF Active Power Filter and SVG Static Var Generator for marine vessels, shipyards, and offshore facilities.

The APF mitigates harmonic currents generated by propulsion drives, shore power systems, welding equipment, and other power electronic loads. This helps reduce interference with sensitive navigation, radar, communication, and automation systems.

The SVG dynamically compensates reactive power from cranes, welding machines, pumps, propulsion systems, and shore power systems. It helps stabilize voltage, improve power factor, and reduce reactive power losses.
