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 n Ideal configuration for dynamically positioned semisubmersible rigs and drillships n Compact cylinder head design n Nodular cast-iron block with integrated ducts for lubricating oil and charge air n Segmental camshaft design n 25° tilt capability in all directions n Engine design based on the higher requirements of heavy fuel oil n High efficiency turbocharger n Cylinder liner, only cooled outside the engine block n Engine control terminal with analog instrumentation in robust cast casing n Connecting rod, oblique split design n Compact module for lower valve drives and injection pump drives with cam followers n 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
