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 shortcircuit 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.
