Marine Generator Service — Naval, Commercial Shipping and Offshore
Marine and naval operators run generator fleets under saltwater corrosion, confined-space generator rooms, vessel dry-dock constraints and class society compliance cycles. TEMISA Power Gen serves main, auxiliary and emergency marine generators for naval vessels (SEMAR), commercial shipping and offshore platforms. Marine-grade rewinding with tropicalization, class society compatible documentation (ABS, DNV, Lloyd's Register) and dry-dock coordination. CFE LAPEM W4200-12 and ISO 9001:2015.

What marine and naval operators are solving today
A marine generator never operates in clean conditions — saltwater, vibration, confined access and dry-dock-driven outage windows are the daily operational reality. Every overhaul has to satisfy the class society surveyor and the vessel chief engineer at the same time.
- Saltwater corrosion accelerating insulation aging and metallic component degradation
- Class society compliance — ABS, DNV, Lloyd's Register, Bureau Veritas or RINA inspection cycles
- Confined-space generator rooms with limited maintenance access in commercial vessels
- Vessel dry-dock windows that constrain when major overhaul work can be executed
- Shock and vibration loading on naval vessels under operating conditions
- Emergency generator readiness for SOLAS or naval mission requirements
- Multi-OEM generator fleets across a single vessel — main, auxiliary and emergency units

FAQ
Frequently asked questions — Marine and naval generator service
Preguntas que recibimos con frecuencia. ¿No encuentras la tuya? Escríbenos a ventas@temisa.mx.
Do you support class society inspections (ABS, DNV, Lloyd's Register)?
Yes. Our overhaul and rewinding documentation is structured to be compatible with class society inspection requirements. Reports include insulation resistance, polarization index, Hipot, surge comparison, IEEE 115 acceptance protocol and dimensional records — the data the class surveyor needs to clear the generator after overhaul. Final class approval is issued by the surveyor, not by TEMISA.
Can you service generators while the vessel is in dry-dock?
Yes. We coordinate with the shipyard and the vessel chief engineer to extract the generator (or send a field crew on board) during the dry-dock window. In-shop overhaul lead time is scoped to fit the dry-dock schedule. For tight windows, we mobilize parallel teams on multiple generators across the same vessel.
Do you tropicalize windings for saltwater service?
Yes. Marine alternator rewinding includes tropicalization — Class F/H insulation, marine-grade varnish (typically polyester or epoxy systems certified for marine service) and VPI impregnation. The rewinding spec is documented under CFE LAPEM W4200-12 with traceability to the materials used.
Do you serve Mexican naval (SEMAR) and commercial shipping clients?
Yes. We have service experience with Mexican naval operators (SEMAR — Secretaría de Marina) and commercial shipping companies. Documentation is delivered in English or Spanish as required by the operator. For naval vessels, we follow the specific procurement and clearance procedures required by the naval authority.
Do you service offshore platform generators?
Yes. Offshore platform generators (oil and gas platforms in the Gulf of Mexico) are supported under our marine and oil & gas sector capabilities. Field mobilization to platforms requires HUET training, BOSIET certification and operator-specific safety clearance — coordinated case by case with the platform operator.
