Features

Engine Design

Proven reliability and durability; Robust diesel strength design prolongs life and lowers owning and operating costs; Assembled, tested, and validated as a package to minimize package vibration and maximize component life; Market-leading power density; Long overhaul life proven in oilfield applications; Core engine components designed for reconditioning and reuse at overhaul

Ease of Installation

Engine and generator are mounted to an inner base, which mounts to an outer base assembly with vibration isolators; Installed with an integral drip tray to provide a single lift installation and to reduce shipyard scope of work complexity

Safety

E-stop pushbutton on instrument panel; Air shutoff and explosion relief valves; Configurable alarm and shutdown features; Extra alarm switches available for customer-supplied panel

Improved Serviceability

Large inspection openings allow convenient access to core engine internals; Reduction of Owning and Operating Costs; Long filter change intervals, aligned with service intervals; Excellent fuel economy - direct injection electronic unit injectors precisely meter fuel

Custom Packaging

For any petroleum application, trust Caterpillar to meet your exact needs with a factory custom package. Cat® engines, generators, enclosures, controls, radiators, transmissions - anything your project requires - can be custom-designed and matched to create a one-of-a kind solution. Custom packages are globally supported and are covered by a one-year warranty after startup. Testing Every Cat engine is full-load tested to ensure proper engine performance.
