13 Drawworks braking systems The drawworks in our standard configuration includes three independent braking systems: Primary active braking system: The drawworks main drive motors, supplied by Aker Wirth, not only have a driving function but are also used for regenerative braking. For braking, the drawworks motors will operate in generator mode and feed back the braking energy into a resistor bank or to the mains until the load is stopped. Regenerative braking can preferably manage braking at low speed or no speed conditions, and can stop the load at predetermined positions. The disc brake represents the third braking system and is used for emergency braking and parking only. The disc brake and the associated callipers are kept open by a hydraulic system thereby providing a fail-safe mechanism. In case of an emergency such as loss of power, hydraulic failure or system failures of the drives, all callipers will be applied. Secondary active braking system: The second braking system is a dynamic brake, which is an electromagnetic braking device. This brake is a high energy absorption device thus maintaining appropriate braking torque at higher drawworks speeds. Under lowspeed or no-speed conditions the eddy current brake can only produce low or no braking torque. Under these conditions the regenerative brake takes most of the load. Emergency and parking braking system: 13

14 Drawworks control systems Autodriller System Aker Wirth offers a complete state-of-the-art Drawworks Control Package (DCP) consisting of DICS - Drawworks Interface and Control System ZPS - Zone Positioning System including dynamic Anti-Collision System functions ECS - Eddy Current Brake Control System ADS - Auto-Driller System WPS - Wireline Protection System DBS - Dual Brake System BBS - Battery Back-up System DICS Drawworks Interface and Control System The DICS is the drawworks control interface to all communication partners such as driller interface HMI, VFD system, MCC system, Zone management system, etc. The DICS comprises also the drawworks control functions for the gear, lube and brake control system. Features: Single interface for all communication partners Full drawworks control of all mechanical functions Simple integration into any HMI system Communication protocols: Profibus DP, S7, Ethernet ZPS Zone Positioning System The Zone Positioning System (ZPS) or so called Anti- Collision System is designed to protect the travelling assembly when approaching the natural limits of the drilling derrick. It will slow down and stop the drawworks when the travelling assembly reaches dedicated positions in the derrick to prevent collisions with the derrick crown or the drill floor. In addition the system calculates the safe braking distance at any time based on the actual load and speed (kinetic energy monitoring). The system is also capable of positioning the drawworks to driller-defined work points to assist the drilling operation. The ZPS is ready to interface to the Zone management systems via the DICS. The PLC of the Aker Wirth ZPS is based on fail-safe hardware components and therefore state-of-the-art design. This design is suitable for fulfilling the requirements of SIL 3.

15 All control systems are based on Siemens S7 programmable logic controls Efficient performance you can trust ECS Eddy Current Brake Control System The ECS is designed to improve the performance and reliability of the eddy current brake while at the same time providing a degree of redundancy by providing independent control of the coils. Features: Brake current control Coil resistance and temperature measurement Separate SCR for each pair of brake coils Alarm indication Water volume and temperature control Drawworks drum speed control from the main drive system. This Auto-Driller system is able to control the ROP triggered by various interactively set parameters and can also be used as an emergency back-up for the main drive. In case of a major failure of the drawworks main drive, the drill string can be secured from the bottom into cased hole at a reduced speed. During drilling, automatic operation control is possible on any of the following parameters: constant speed, constant weight on bit, constant standpipe mud pressure and constant DDM or top-drive torque. Additionally the operator can interactively set limits to the drilling parameters. ADS Auto-Driller System The integrated auto-driller as independent system confirms redundancy to the main drive system. AC frequency controlled independent drive arrangement Maximized drilling efficiency Automatic drilling operation Minimized downtime Smooth block control The capability to build in an Auto-Driller is easily given by adding an extra AC drive arrangement, independent A high degree of sensitivity and accuracy of control can be achieved. This allows maximum service life of the drilling tools and a reduced workload for the drilling crew while providing maximum adherence to the desired drilling parameters.
