• The Power Control Room (SCR House) will be Top Lift Only, and be equipped with roof mounted handrails and an access ladder mounted on the outside (just as the original)

4- Model 1500 I-DRIVE SCR Drive Cubicles each equipped with electronic controllers, primary and secondary assignments, and 600V feeder circuit breaker switches

* KW/KVA limiting circuitry monitors the available power and compares it against the KW/KVA in use, so that the power consumed by the SCR system does not exceed the available power on the line.

* Control power will be 120 VAC for best contact integrity and line noise immunity. The system will be provided with a control power transformer to provide control for standard contactor logic and alarm function. Each SCR converter section will be assignable to two (2) loads. Assignment switching will provide 100% redundancy in case of converter or load failure.

Motor braking will be resistive loading to prevent possible generator over-speed under light loading conditions. Full control will be maintained to protect against impact shock to the driven equipment.

5) I-Drive module is a standard unit; interchangeable on any system, on shore/off-shore, single motor, two motor operation and series or shunt motors.

I-Drive Power Limiting protects the diesel engine/generator set(s) from dropping "Off Line" due to an overloading. When maximum KW or KVA capacity has been reached, the system "phases back" the outputs of the SCR drives connected to the AC Buss, and thus prevents the generator sets from dropping off line due to an overload.

The I-Drive SCR Control Module accepts four different current limit settings, which corresponds to the four possible assignments of the SCR drive. The I-Drive SCR DC cardrack test panel has four potentiometers where the Current Limits are set. The current limit settings are a separate module from the D/C module which allows changing the D/C module without resetting current limits.

The I-Drive Firing Circuit Regulator works in conjunction with the AC Buss Phase Sensing and the Six Gating Pulse circuits. The SCR firing pulses are referenced to the Three AC Lines, and timed to trigger the respective SCR"s at the correct instant.

There are six firing pulses (each spaced 60 degrees from the previous) in each cycle and all are adjusted simultaneously by the firing enable circuit to get the correct SCR firing angle.

This feature allows the I-Drive SCR drive to deliver more current for a short period of time than what is preset with the current limit Calibration as set on the DC cardrack test panel. This feature can be used in situations where high current is needed for short periods of time, I.E. for a drawworks motor. The amount of overcurrent allowed is set at the Timed-Overcurrent Module, from 110% to 130% of the present current limit for approximately 60 seconds. After the 60 seconds period, the current will revert to the normal current limit as set at on the I-Drive DC cardrack test panel so as not to damage or overheat the SCR bridge.

1. Over-temperature: When the SCR Blower is lost or the SCR house internal ambient temperature rises to an unacceptable level so that proper cooling of the SCR’s is not possible, a set of thermo-switches, mounted on the SCR bridge heatsinks detect when the temperature goes above 70 degrees C and signals an alarm condition

2. Blown Fuse: The SCR bridge has a set of semi¬conductor fuses for the protection of the SCR"s. If any of the fuses open, the FFAS (fuse failure alarm signal) is activated (isolated contact closure) and the firing pulses to the SCR bridge are automatically inhibited

The I-Drive SCR drive is of modular design, compact, NEMA type 1 A construction WITH DRIPSHIELDS, front access only. The D.C. control module contains the circuitry necessary to control the SCR Bridge’s output. The module is interchangeable between all I-Drive SCR systems. The module is furnished with no adjustments necessary. The module is easily disconnected for replacement should the need arise. This makes for a minimum of “down-time” should a failure occur.

The I-Drive SCR Bay cooling is assisted by a squirrel cage blower forcing air in the direction from bottom to top of the cabinet. Air is drawn in through a filter in the lower section of the front door. It then proceeds over the contactors, DC buss, and into the blower intake. The blower’s output airflow goes directly into the plenum below the SCR bridge, into the bridge heatsinks (the point of the most air flow resistance), out the top of the bridge, upward past the circuit breaker and AC buss, and out the top of the cabinet.

The I-Drive SCR Bridge is composed of three (3) identical and interchangeable modules (Phase Cells). Each Phase Cell has an AC input flag, a minus DC output flag, and a plus DC output flag. In the Phase Cells the discrete SCR devices have heatsinks on both sides. Thermodynamics proves that this allows the SCR devices to operate at a lower temperature than single sided “bricks” for the same device current. The lower the operating temperature, the more reliable the SCR device is. The system is designed for low maintenance and to operate in ambient air temperature up to 50 degrees C without air conditioning.

The I-Drive drawworks dynamic brake will slow the drawworks motors from full speed within eight to ten seconds after the foot throttle is released. The power of the free wheeling motor is fed back into a resistor bank. During normal operation the dynamic brake system is non-operative, and the drawworks is either OFF or operating at the desired cathead speed. If however, at any time the motor speed is higher than the DW throttle speed setting, and the foot throttle is OFF, the dynamic brake system is actuated, reducing the motor speed to the DW throttle setting.

The I-Drive foot throttle is constructed of rugged stainless steel throughout; built to withstand the environment normally encountered on the rig floor.

The I-Drive Drillers Console will be NEMA type 4X construction of #316 stainless steel1 outdoor weather proof and provided with air purge/pressurization fittings to allow use in a Class 1, Division 2 hazardous area. All assignment switches, hand throttles and controls will be front mounted on the door. All meters, instruments and annunciators will be mounted behind the front door with a safety glass view window provided to view the meters and instruments, etc. The door will be attached with stainless steel hinges and positive latching stainless steel latches.

One set of I-Drive generator control cubicles consisting of three (3) each I- DRIVE model 1200 engine/generator control modules, breakers and related equipment for the control of three (3) each engine/generator sets and a synchronizing and ground detection cubicle.

I-Drive AC Electronic Control Section contains the AC cardrack. Three modules plug into the AC cardrack. They are the Engine Electronic Governor module, Generator Electronic Voltage Regulator module and the Metering control module. All external connections to the AC cardrack are by barrier strip (screw type).

COOLING SYSTEM - In order to ensure compliance in use, optional or customer-supplied radiators must be capable of rejecting enough heat to allow proper operation at worst case site conditions, and also must supply 122 deg F (50 deg C) SCAC cooling water to the aftercooler inlet, with an SCAC flow rate of at least 100 GPM (379 l/m) with an ambient temperature of 86 deg F (30 deg C) and at-site conditions (including altitude considerations). Maximum allowable SCAC flow rate is 115 GPM (435 l/m). RADIATOR COOLED LAND BASED: Outlet controlled thermostat and housing. Jacket water pump, gear driven. Dual outlets: 88.9 mm O.D. (3.5 in) elbow hose connections. Aftercooler fresh water cooling pump (SCAC), gear driven centrifugal SCAC pump circuit contains a thermostat to keep the aftercooler coolant from falling below 30 deg C (85 F).

ENSCO 71 is a Jack-Up drilling rig which was originally constructed at the Hitachi Zosen shipyard in 1982. The original GE motor controls comprised five 1163 KVA generators and four 1800 ADC SCR units with associated auxiliary transformer feeders and jacking units. The SCRs were assignable to two 1600 HP twin-motor Mud Pumps, a twin motor 2000 HP Drawworks and a 1000 HP Rotary Table. A separate feeder drives a 1110 HP Top Drive. A fifth SCR was added by Hill Graham Controls in 1985 to power a third 1600 HP Mud Pump, which was cabled to the main busbars.

In early 2012, a decision was made to add a fifth 2500 KVA generator and an additional auxiliary transformer, to close-couple these to the main switchboard via a bus tie circuit breaker, and to include a dedicated feeder for the fifth SCR. A sixth SCR was also included in the switchboard extension to provide an alternative drive source for the third Mud Pump, effectively removing this load from the main switchboard. The switchboard extension, including full integration with the existing GE and Hill Graham equipment, was engineered and built by Zeefax.
