12CM43C Offshore Generator Set

  • Overview

Engine Design


 - World-class reliability and durability
 - Incorporates years of proven component reliability and
 - durability in marine industry
 - Medium speed long-stroke engine design
 - Ideal configuration for dynamically positioned semisubmersible rigs and drillships
 - Compact cylinder head design
 - Nodular cast-iron block with integrated ducts for lubricating oil and charge air
 - Segmental camshaft design
 - 25° tilt capability in all directions
 - Engine design based on the higher requirements of heavy fuel oil
 - High efficiency turbocharger
 - Cylinder liner, only cooled outside the engine block
 - Engine control terminal with analog instrumentation in robust cast casing
 - Connecting rod, split off design
 - Compact module for lower valve drives and injection pump drives with cam followers
 - Optional Flexible Camshaft Technology (FCT)

Ease of Installation


 - Standard modular design allows for ease of installation and reduced complexity
 - Installation-friendly, due to pumps and filters installed on the engine
 - Cooling water system with simple plug-in connections
 - Full range of factory-installed engine attachments allows customization and reduction in installation time

Packaging Concept


 - Assembled, tested, and validated as a package to minimize package vibration and maximize component life

Improved Serviceability


 - Large inspection openings allow for convenient access to core engine internals for easier serviceability
 - Core engine components designed for reconditioning and reuse at overhaul
 - Worldwide dealer network with factory-trained technicians means that parts and support are never out of reach
 - Simplified parts spectrum by using single-pipe exhaust gas ducting
