When the going gets though

High power, robust design, and low fuel consumption are the outstanding features of MTU's Electric Drilling Package.
Simple, safe operation and serviceability
MTU engineers have designed the EDP to be both powerful and easy to use and service. Access to common maintenance items such as filters, belts and batteries is quick and easy while belt and coupling guards, along with in board-located engine exhaust manifolds, provide safeguards against operator injury. Oil and fuel connections are facilitated by protected quickconnect fittings located conveniently at the front of the skid. Heavy-duty air filters, duplex fuel filters and a standard lube oil centrifuge spinner help extend maintenance intervals. In addition, the coupling element can be exchanged without having to move the generator, thus preserving ist original equipment alignment and eliminating the lengthy generator realignment process typically required during coupling service. MTU engineers also created a carefully customized, easily transportable skid base for the EDP, using finite element analysis to help find the ideal balance between weight and strength and to ensure stability and durability. The EDP’s control panel features a Murphy fullcolor display, analog gauges for oil pressure and temperature and coolant temperature, tachometer with hour meter, start/stop and emergency push buttons, a three-position selector switch including a lockout switch for maintenance, and IP65 protection. Output from generator sensors is integrated into the display panel to monitor bearing and winding temperatures. MTU even offers an optional integrated GPS-based system for remote monitoring and diagnostics of all engine data, which can also be used by service technicians to locate the drilling rig anywhere in the world.
Single-source responsibility means peace of mind
It’s clear that MTU listened and learnedwhat today’s drilling contractors need in a rig power system to compete and succeed in their rapidly evolving industry, and then designed the EDP to suit. But planning and executing the EDP design as a unit, rather than as a disparate system of independently outsourced components, virtually guarantees the high performance and peace of mind that drillers demanded. Because the EDP is a completely factory-built package, MTU has single-source responsibility for the entire system, a unique and valuable asset for drillers who already have enough to monitor on a hectic drilling job. Every component of the package is factory-certified and covered under MTU’s warranty, with EDP support available at authorized service locations around the globe. In the end, that combination of function-specific design and unrivaled worldwide support that sold Lyle Eastham and Big E on the very first MTU EDP. “I have a lot of positive feedback to give to the MTU team,“ he declares. “I think they’ve done a lot of hard work to design an engine that is going to be a presence in the land drilling industry…I appreciate that, because my job would not be possible had it not been for that engineering work. My job is to deliver a consistent service to my customers. I cannot do that without MTU delivering a consistent level of service to me.“
