A modular, high performance AC top drive for demanding drilling applications. Technical image of the ECI **0 Top Drive Tescos ECI top drive system represents a significant advance in electric top drive technology. Traditional induction or brush style DC motors have been replaced with liquid cooled, permanent magnet synchronous motors. These motors, capable of producing **0HP each, set the standard for reliability, durability and power density. Compact enough to fit into any triple mast, the ECI provides the performance and pipe handling features required for medium and deep drilling applications. The ECI system includes a uniquely engineered power system suitable for all drilling requirements. This system is compatible with most **0V AC rig power systems. The ECI top drive is available with an integrated swivel or can use the customers swivel. Casing load ratings of **0 or **0 tons are available. If applications require, the load path can be easily reconfigured. The modular ECI is available in **0 and ***0HP configurations. An ECI **0 system can also be upgraded to a full ***0HP. Operational Advantages The complete system including the top drive, torque system and power unit can be installed in less than one day. In most cases, no rig modifications are necessary. The ECI can be interfaced with the existing power supply with minimal degradation to rig power. The system is monitored using a dedicated diagnostic computer and specialized software. PA*4 permanent magnet synchronous motors have been successfully tested to *0G triaxial loading, making them the ideal choice for rough drilling environments. Modular design of the system allows drilling to continue at reduced HP with one motor. A double ball mud saver/safety valve is incorporated into the system design. The ECI package includes a specially designed torque system. The track/torque bushing configuration is simple to install and requires minimal maintenance. The ECI offers an expanded suite of hydraulic pipe-handling functions including elevator link-tilt, an extend/retract feature for making mousehole connections up to *0 in. from well center, **0° pipe-handler rotation, and grabber. The ECI grabber acts as a back-up tong for making or breaking connections and will accommodate tool joints from 3 in. to **3/4 in. OD. The entire ECI can be transported in three standard *0 ft. sea containers.
