What buyers should know first
Marine generator inquiries need more detail than a basic land-based generator request. Before quotation, confirm vessel type, duty, voltage, frequency, cooling method, installation space, classification or survey needs, and whether the set is for auxiliary power, emergency use, or port operation.
In practice
Marine buyers should provide installation drawings where possible and ask the supplier to confirm cooling, exhaust, vibration isolation, and service clearance.
Procurement checklist
- Confirm running load, starting load, voltage, phase, and frequency.
- State whether the generator is for standby duty, prime duty, or mixed project use.
- Confirm silent canopy, open-frame, containerized structure, ATS, or manual transfer needs.
- Send altitude, ambient temperature, installation space, ventilation, and noise limits.
- Request datasheet, engine model, alternator model, controller details, drawings, and packing dimensions.
Common configuration mistakes
Many RFQ problems start when buyers compare only kW or kVA. Rating basis, motor starting demand, site condition, fuel autonomy, service access, and transfer equipment can change the correct configuration. For project comparison, review marine diesel generator set options and the diesel generator product catalog.
FAQ
What should be sent before asking for price?
Send the load list, voltage, phase, frequency, expected running hours, site condition, enclosure preference, and transfer requirement.
Is standby rating the same as prime rating?
No. Standby rating is for emergency backup. Prime rating is used when the generator carries variable load for longer operating periods.
Should ATS be included in every quotation?
ATS should be included when automatic utility-to-generator transfer is required. Manual or temporary systems may use different switching arrangements.
Can the supplier choose the final size from limited information?
A supplier can suggest a planning range, but final sizing should be checked against real load, starting current, site condition, and project engineer requirements.
