Five sets of Yuchai 16VC marine generator sets are configured as the core propulsion power system for an offshore wind turbine heavy transport vessel, supplying stable electric power for full-electric propulsion, dynamic positioning and all marine auxiliary loads during transoceanic wind component transportation.
1. Project Background
Offshore wind turbine transport vessels undertake long-distance marine transportation of oversized wind towers, blades and generator nacelles. Operating in variable offshore wave, salt fog and high humidity marine environments, the vessel's propulsion system requires continuous stable power output, strong anti-fluctuation performance and full marine corrosion protection. Reliable redundant power is critical to guarantee navigation safety, precise berthing and DP dynamic positioning when approaching wind platforms.
2. Why Adopt 5 Sets Yuchai 16VC Units
The five-unit layout realizes full N+1 power redundancy design for the vessel's all-electric propulsion system. Under normal transit conditions, 3–4 units run to match navigation load, with one standby unit reserved for maintenance or sudden heavy sea state power surge. All 16VC power packs adopt professional marine anti-salt mist, anti-corrosion coating and closed air intake design to resist long-term marine salt fog erosion. The unit features excellent transient load response to cope with frequent power fluctuation during speed adjustment, side drifting and dynamic positioning near wind farms. Multi-unit parallel control ensures balanced load distribution and avoids single-unit overload during peak propulsion demand.

4. Operation Value After Matching
Since being equipped on the wind transport vessel, the 5-unit Yuchai 16VC power system provides steady power support for long-distance cross-sea transportation of oversized wind turbine components. The redundant layout effectively eliminates navigation risks caused by single unit failure. Marine anti-corrosion structure greatly extends service life in coastal and open sea working conditions, cutting long-term vessel operation and maintenance cost. Excellent fuel economy reduces daily marine fuel expenditure during long voyage transit.
5. Frequently Asked Questions (FAQ)
Q: Why choose 5 units instead of fewer sets?
A: Wind transport vessels face constantly changing propulsion loads and strict DP positioning power demand. The 5-unit N+1 redundant scheme ensures enough reserve power for rough sea navigation and equipment maintenance without suspending transportation missions.
Q: What special marine treatments do these 16VC units have?
A: The whole machine adopts thick anti-salt mist paint, special marine air filtration system and anti-corrosion pipeline fittings, adapting to long-term high humidity, high salt offshore working environment.
Q: Can multiple 16VC units run in parallel automatically?
A: Yes, the supporting central control system realizes automatic parallel connection, average load distribution and automatic standby unit startup when any running unit breaks down.
