Variable Frequency Drives - Electrical, Lighting and Power
Marine variable frequency drives (VFDs) control the speed and torque of AC motors used aboard ships and offshore vessels. They improve energy efficiency, provide soft starting, and support automation of pumps, fans, compressors, winches, thrusters, and other shipboard auxiliaries.
ProShipWorks provides end-to-end support to source and supply Variable Frequency Drives for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Typical requirements include IEC 61800-5-1 for electrical safety, IEC 61800-3 for EMC, IEC 60092-504 for special features of control and instrumentation equipment, IEC 60533 for electromagnetic compatibility on ships, and applicable IACS E10 requirements. Certification depends on the exact drive configuration and vessel project. |
|---|---|
| Class Approval | Marine-approved configurations may be available with DNV, ABS, Lloyd's Register, Bureau Veritas, and ClassNK approvals. Approval is model-, enclosure-, installation-, and application-specific; verify the manufacturer's current type-approval certificate before procurement. |
Installation, Maintenance & Safety Information
| Installation Notes | Install according to the manufacturer's marine installation manual, approved drawings, and vessel classification requirements. Provide suitable ventilation or cooling, cable segregation, grounding, EMC measures, short-circuit protection, and accessible isolation. Confirm motor compatibility, rated current, overload duty, harmonics, and bypass requirements. |
|---|---|
| Maintenance Tips | Inspect terminals, cooling fans, filters, heat sinks, enclosure seals, and ventilation paths at planned intervals. Remove salt deposits and dust using approved methods, check alarms and stored fault logs, and verify cooling performance. Re-torque electrical connections only according to the manufacturer's procedure. |
| Safety Notes | Isolate, lock out, and verify absence of voltage before service; DC-link capacitors may remain charged after shutdown. Use appropriate PPE and arc-flash procedures. Do not bypass protective functions, operate with covers removed, or connect a megohmmeter to the drive without following the manufacturer's instructions. |
