MH 2800 EG AC Drawworks:
Wirth gear-driven drawworks have created a new standard in terms of performance.
They provide increased safety, performance and availability while reducing weight, noise and vibration.
The GH 2800 EG AC Drawworks is furnished with 2 each Siemens AC Motors, rated 890 kW, Type 1SA2531-ONA03, ATEX.
An AC Drive (Frequency Converter) system is also available for the two drawworks motors:
Comprising two Siemens 1200 kW, 1100 A AC Drives mounted in one panel (circa 5.75 m long) in a common LER container.
Siemens model 6SE7041-2WL60-1AA0
Power requirement is 690 VAC, 3 PH, 60 HZ.
1 General
The Drawworks has a nominal rating of 2300 HP and is driven by two variable speed 690V SIEMENS AC motors.
The Drawworks Main Drive Motors have a dual function and are used to drive and brake the Drawworks.
2 Associated Systems & Packages
The Drawworks Main Drive Motors are powered from 690V variable speed drive.
The Drawworks package is a stand alone sub-system.
The communication between the respective Drawworks systems such as Drawworks Control System and Anti Collision System are established by the Drawworks Interface PLC (DIP). DIP communicates with the ASDS system via a Profibus DP serial line. Safety related signals i.e. emergency stop signals shall be hardwired.
Interface to the MCC will be established via the ASDS Profibus DP serial link. Siemens technical literature covering these systems should be referred to for definitive details of these systems.
3 Braking Systems
The Drawworks is equipped with two braking systems, these are:
3.1 Regenerative Brake
The regenerative Braking is the drawworks main braking system. During dynamic braking using the regenerative mode energy will be transfer to breaking resistors. The motor braking is generated from the DIP and executed by the Siemens Drive System. Detailed system description may be found in their technical
documentation for the VSD packages.
3.2 Disc Brake
The Disc Brake is operated via the Drawworks Control Cubicle. The Drawworks Disc Brake is coupled directly to the Drawworks drum shaft .The disc braking system comprises of a rotor disc, complete with two sets of callipers and a Hydraulic Power Unit (HPU) for brake operation.
This is a part of a Well Intervention Package. Link to more info for Listing ID: UL 04556.
AI DESCRIPTION
The Wirth GH 2800 EG is an AC drawworks system designed for drilling operations, featuring a single drum with disc brakes and powered by two Siemens AC motors. It's in excellent condition and has minimal operational hours, making it a reliable choice for lifting and lowering drilling loads.
