Application 2. Offshore Platform Pumps Application 2. Offshore 2. Offshore Platform Offshore Platform Pumps Platform Pumps Pumps Five production pumps on this offshore platform feed oil into a pipeline taking the product to onshore facilities. Three of the 2,250 hp pumps were under control of adjustable speed drives to adjust the total flow to demand, and the other two were on fixed Five production speed. The pumps original on drives this offshore were obsolete platform and feed spare oil into parts a pipeline were difficult taking to the obtain. product In to addition, onshore the facilities. older drives Three required of the power 2,250 hp factor pumps correction were under and power control line of filters adjustable to keep speed the power drives clean. to adjust These the total filters flow were to demand, very noisy and for the employees other two working were on in the fixed equipment speed.

In addition, the older drives required power factor correction and power line filters to keep the power clean. These filters were very noisy for employees working in the equipment room for long periods. The oil production company wanted to: The • oil production Replace the company old drives wanted with new to: maintainable drives.

Throughout the process, strong application support from the TMEIC GE engineering office in Virginia proved valuable. The first of the three old drives was replaced with a Dura-Bilt5i MV. After evaluation, a second Dura-Bilt was installed on the second pump. Each drive is equipped with the components for synchronous bypass in the future, although the actual bypass The contactors first of were the three not old initially drives included. was replaced A power with study a Dura-Bilt5i performed MV. by After TMEIC evaluation, GE showed a second that the Dura-Bilt remaining was installed old drive on could the second operate pump. without Each any filters drive since is equipped it represents with the a small components portion for of the synchronous load the bypass platform. in the future, although the actual bypass contactors were not initially included. A power study performed by TMEIC GE showed that the remaining old drive could operate without any filters since it represents a small portion of the load on the platform. Benefits of the Dura-Bilt5i MV Pump System Benefits of the Dura-Bilt5i MV Pump System High Reliability. Advanced design including use of medium voltage Insulated Gate Bipolar Transistors (IGBTs), oil-filled capacitors, a built-in copper wound transformer, and surge and transient protection creates High Reliability. a drive with Advanced high reliability. design including use of medium voltage Insulated Gate Bipolar Transistors (IGBTs), oil-filled capacitors, a built-in copper wound transformer, and surge and transient protection creates a drive with high reliability. Low Harmonic Distortion. The 24-pulse rectifier’s low harmonic impact of less than 1.5% distortion gives clean operation without the use of filters, allowing the original filters to be disconnected. Low Harmonic Distortion. The 24-pulse rectifier’s low harmonic impact of less than 1.5% distortion gives clean operation without the use of filters, allowing the original filters to be disconnected. High Power Factor. The new system has a very good power factor of better than 0.95 and does not require any external power factor correction equipment. High Power Factor. The new system has a very good power factor of better than 0.95 and does not require any external power factor correction equipment. Compact Drive. The Dura-Bilt drive system fits in a smaller space than the original system because the transformer is integrated into the cabinet and the heat pipe cooling allows a very compact drive.

Pump System One-Line Diagram Platform MV Bus In this diagram, Drive 1 is shown with a synchronous bypass option, which can be added in the future. This option will allow the drive to: DB5i MV Drive 1 Motor 1 DB5i MV Drive 2 Motor 2 Older Drive Motor 3 Motor 4 Motor 5 • Start Motor 1 with low current inrush. • Bring the motor up to synchronous speed. • Synchronize the motor with the supply bus. • Put the motor across the line and disconnect the drive from the supply. • Allow Drive 2 to control Pump 2 flow as required by the flow demand. This configuration allows Motor 1 to run at full speed without the heat losses in the drive. The synchronous option can be extended to the second drive if required. Pump 1 Pump 2 Pump 3 Pump 4 Pump 5 Future Improvements The customer has the option in the future to retire the last old drive and install contactors on all motors and the two drives. With appropriate PLC control logic, the system will allow either Dura-Bilt to start and run any of the five motors, and put them across the line. This future system improvement will provide: • The maximum flexibility to operate the pumps under a wide range of situations. • Soft starting available for all motors to minimize system impact and deterioration of the windings caused by inrush current. • Reduction in the impact of drive downtime since no motor is dedicated to any drive.
