Shaft Generators - Electrical, Lighting and Power
A marine shaft generator converts main-engine shaft power into electrical power for shipboard services. It can reduce auxiliary-engine fuel consumption and support lighting, hotel loads, pumps, navigation equipment and other electrical systems during passage.
ProShipWorks provides end-to-end support to source and supply Shaft Generators 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 | Marine installations commonly reference IEC 60092 series, including IEC 60092-301 for electrical rotating machinery and IEC 60092-302 for low-voltage switchgear assemblies. Manufacturer and vessel-specific requirements also apply. |
|---|---|
| Class Approval | Systems may be designed, tested and approved to the requirements of DNV, ABS, Lloyd's Register, Bureau Veritas, ClassNK or another applicable classification society. Approval depends on vessel type, installation and project specification. |
Installation, Maintenance & Safety Information
| Installation Notes | Confirm shaft speed, torsional characteristics, power rating, voltage, frequency and alignment before installation. Install the generator, gearbox, coupling, control system and protection equipment according to the approved drawings and class requirements. Perform insulation, rotation, synchronization and load tests before commissioning. |
|---|---|
| Maintenance Tips | Inspect bearings, couplings, shaft alignment, ventilation, cooling and cable terminations at scheduled intervals. Monitor vibration, temperature, insulation resistance, excitation and protection alarms. Follow the manufacturer's lubrication, inspection and overhaul intervals. |
| Safety Notes | Isolate and lock out the main engine, shaft line and electrical system before work. Prevent unexpected shaft rotation and backfeed from the main switchboard. Use appropriate arc-flash, electrical and rotating-equipment protection, and ensure testing is performed by qualified personnel. |
