24 DrawworksDrilling equipmentWirth multi/two-gear drawworks –braking systemsThe drawworks in our standardconfiguration includesindependent braking systems.two independent disc brake systems to achieve maximumsafety. In the event of a reduction or loss of braking forceof the master brake, the second brake system will engageaccordingly to compensate for the loss. Thus permitting fulland continual operation of the drawworks until remedial workcan be performed on the master brake.Control of the drawworks disc brake, gear selection andoperation of the auxiliary drives are controlled by theprogrammable logic controller (PLC) within the drawworksinterface control system (DICS). Braking requirements aredetermined by the ZPS programmable logic controller whichobtains information from the drawworks sensors, the “DCS”and the “VFD”.Primary active braking system:The drawworks main drive motors, supplied by Aker Solutions,not only have a driving function but are also used forregenerative braking. For braking, the drawworks motors willoperate in generator mode and feedback the braking energyinto a resistor bank or to the mains until the load is stopped.Regenerative braking can preferably manage braking atlow speed or no speed conditions, and can stop the load atpredetermined positions.Secondary active braking system:The second braking system is an Eddy current brake, whichis a dynamic electromagnetic braking devicee. This brake isa high energy absorption device thus maintaining appropriatebraking torque at higher drawworks speeds. Under lowspeedor nospeed conditions the eddy current brake can onlyproduce low or no braking torque. Under these conditionsthe regenerative brake takes on most of the load. The eddycurrent braking energy is dis- sipated by water cooling.Emergency and parking brake system:The disc brake represents the third braking system and isused for emergency braking and parking only. The disc brakeand the associated callipers are kept open by a hydraulicsystem thereby providing a fail-safe mechanism. In case of anemergency such as loss of power, hydraulic failure or systemfailures of the drives, all callipers will be applied.Under normal operation conditions the callipers are onlyapplied for parking, holding the load in a static condition andthus preventing its uninten- tional lowering or raising.Wirth offhore multi and two gear drawworks are equippedwith the Wirth Dual Brake System (DBS) which is anintelligent redundant PLC controlled system incorporatingThe ZPS PLC algorithm calculates the degree of brakingrequired and transmits the relevant signals to the brakingsystems (“VFD” and “ECB”). The main regenerative brakingsystem is the primary braking system. It is supplemented bythe eddy current brake if necessary. The third braking systemoperates in combination with the primary and secondarybraking systems.

We keep your mud pumps running in first class condition – providing onsite inspections, repairs and complete overhaul as well as all associated parts.

Periodically we’ll inspect for wear, cracks and damage to critical components such as bearings, bull gear and pinion, conrods and crossheads. We’ll check the condition of your seals and other rubber goods and look for oil contamination. We’ll inspect your frame and ensure your pump is set up as per the manufacturer’s recommended tolerances, providing feedback and detailed reporting.

Where overhaul is required we’ll take care of complete disassembly, cleaning and NDT. Repairs will be made to machined components as necessary. Bearings, seals and other components will be replaced in line with our inspections. Motors will be overhauled, lube systems serviced and pulsation dampeners recertified. We’ll also check your fluid ends are in spec and can repair or replace. Your pump is then fully reassembled and commissioned.
