Rating Description These modules are to be used in continuous operation at varying load offshore drilling applications where maximum power is needed for short periods of time during initial starting or sudden overload. Refer to engine data sheet for additional information.
Features Single-Source Supplier – The entire power module is designed and manufactured in facilities certified to ISO 9001. Cummins Heavy-Duty Engine – Rugged 4-cycle industrial diesel delivers reliable power, low emissions and fast response to load changes. Generator – Form-wound stator and rotor; designed, tested and sized for drilling rig service; Industry-standard pitch windings; low waveform distortion with non-linear loads; fault-clearing short-circuit capability. Control System – Engine monitoring and shutdown functions with easy-to-read C-Command Elite panels for critical parameters, alarms and fault code information. Testing and Validation – Prototype-tested to verify computer-aided designs, confirm torsional stability and system functionality. Every Cummins engine is dynamometer-tested to ensure optimal engine performance. Low Exhaust Emissions – Engine certified to IMO Tier II and EU Stage IIIA compliant.
Warranty and Service – Backed by a comprehensive warranty and worldwide distributor network.
