40-250kVA Diesel Cummins Generator Marine

Product Overview

The 40-250kVA Diesel Cummins Generator Marine integrates Cummins’ global reputation for reliability with specialized maritime engineering, delivering critical backup power for commercial and naval vessels. Powered by Cummins’ proven NTA855-DM marine engines—renowned for durability in saltwater environments—it achieves ≤85dB(A) noise levels (at 7m) and efficient 48.94L/h fuel consumption (on 250kVA model at full load). Its compact design (≤2,500kg for 250kVA unit) and IP23-rated enclosure (resistant to salt spray and humidity) make it suitable for installation in confined marine engine rooms.

Features

High Torque Output: Delivers 4,500 N·m torque at 1,800 rpm, providing robust power to drive propellers, thrusters, and heavy marine equipment—ensuring reliable performance even during sudden load changes common in vessel operations .

Remote Monitoring & Management: Cummins’ Marine Insight system enables real-time tracking of engine health, fuel usage, and emission levels via satellite or cellular connectivity, with diagnostic alerts sent directly to shore-based maintenance teams—optimizing service scheduling for vessels .

Certifications: Certified by Lloyd’s Register (LR) and compliant with IMO Tier II emissions standards, with optional ABS and BV approvals, ensuring it meets the strict safety and environmental requirements of global maritime authorities .

Applications

Naval Vessels: Powers communication systems, radar equipment, and emergency life support systems, with redundant power configurations (parallel operation) to ensure mission-critical functionality during military operations.

Offshore Rigs: Supports drilling equipment (mud pumps, hoists), living quarters (HVAC, lighting), and safety systems (fire suppression) on offshore oil and gas platforms, with corrosion-resistant coatings (epoxy primers and polyurethane topcoats) protecting against saltwater damage.

Ferry Services: Ensures reliable power for passenger amenities (lighting, restrooms, catering), propulsion systems, and navigation equipment, with 24,000-hour overhaul intervals for main engines—minimizing service disruptions for daily ferry routes .

FAQ

Q: What alternator brands are used?

A: Standard units feature Stamford HCM434D alternators (known for low harmonic distortion ≤3%), with optional upgrades to Marathon MP-H-250-4 alternators for applications requiring enhanced power quality, such as sensitive electronic navigation equipment .

Q: Can it integrate with renewable energy systems?

A: Yes, its flexible control system allows integration with onboard solar panels and wind turbines, enabling peak shaving (reducing diesel use during daylight hours) and load balancing, which can reduce diesel consumption by up to 30% on hybrid-powered vessels .
