Benefits & Features
Engine Design
- World-class reliability and durability - Incorporates years of proven component reliability and - durability in marine industry n 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 n High efficiency turbocharger - Cylinder liner, only cooled outside the engine block - Engine control terminal with analog instrumentation in robust cast casing n Connecting rod, oblique split design - Compact module for lower valve drives and injection pump drives with cam followers - 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 n 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
