High pressure triplex mud pumps

5 High pressure triplex mud pumps Drilling equipment

The Wirth TPK series by Aker Solutions of tough, field proven models for high operating pressure and large flow include:

n Ratings from 800 to 2 200 input hpn Rear or top-mounted skid arrangementn Belt, chain or gear-driven configurationsn AC or DC drive motor configurationsn Operating pressure from 5 000 to 10 000 PSI

Wirth triplex pumps are extremely compact and occupy a minimum of space yet provide the high volume and high pressure capabilities necessary for today’s competitive drilling practices.

Wirth triplex pumps are engineered to produce a very high work capacity with the minimum RPM, reducing stress and wear to vital components. The long stroke design reduces the number of load reversals in heavily stressed components and increases the life of the fluid end parts through reduced speeds and valve operation. The fluid end has practical separate suction and discharge modules including the hydraulic valve closure system.

The hydraulic quick release system offers minimal downtime when replacing fluid end parts.

Main features of Wirth mud pumps:n Optimal smoothness of operationn Compact design, less weightn Pump drive units for permanent load operation, with a high degree of stabilityn Gear wheels and drive shaft of wear-resistant, heat treated steeln Hydraulic Quick Release Systemn Independent lubrication systemn Long lifespan of consumables itemsn Surveillance and control elements for early recognition of failuresn Full material traceability as standardn Fluid ends in stainless steel (optional) for increased life

Aker Solutions has manufactured pumps since 1905, the first pump bigger than 1 000 hp in 1961, followed by the 2 000 hp milestone in 1974.

Reducing downtime and maintenance costs is one of our major goals. Experience shows that Aker Wirth mud pumps, designed for longevity, are the most reliable, field proven and innovative units on the market. Constant improvements and new ideas reflect this.

Two independent in-house test stands demonstrate mud pump performance under full load conditions with high pressure testing up to 10 000 PSI. This assures highest possible quality control.

Aker Solutions also offers additional fluid end consum-ables suitable for various mud pumps, such as different type of valves, liners and pistons for each individual application.

To meet your requirements from desert to arctic environmental conditions, Aker Solutions provides full line of triplex, high pressure mud pumps. They can handle any drilling requirements for onshore or offshore applications.

Hydraulic quick release system

The hydraulic quick release system allows the maintenance crew to carry out routine operational piston / liner changes and fluid end maintenance with ease and a minimum of tools in complete safety.

This system ensures the highest possible degree of safety during maintenance procedures and therefore complies with current HSE requirements.

This hydraulic system is a significant factor with regards to our philosophy concerning safe, effective and easy maintenance.

The unique hydraulic tensioning system employs a hydraulic hand pump or a hydraulic power pack with connection hose and snap connector. Once the correct pressure is applied to relevant components, retaining nuts can be removed by hand.

This system ensures that an equal and correct, precalculated torque, which cannot be exceeded, is applied to all bolting, thus substantially increasing equipment lifespan when compared to traditional mechanical maintenance routines.

Wirth mud pumps premium line products are equipped with a fully integrated, patented hydraulic quick release system. This enables safe and easy maintenance of fluid end parts, i.e. fast-change tensioning system for fluid ends, for liner retention, changing valves and easy opening of valve covers.

The heave compensated drawworks embodies the same basic principle as any other drawworks. A wire rope runs from a deadline anchor over a crown block and a travelling block to a rotating drum powered by several motors. The heave compensated drawworks is used in normal drawworks operation to raise and lower drill string, liner and casing assemblies. The heave compensated drawworks is used in heave compensation mode when connecting the BOP, drilling, testing, etc, during fixed-to-bottom operations. Heave compensation is realised by measuring the vessel movements in the vertical plane and dynamically adjusting the position of the traveling assembly accordingly. The primary goals of the heave compensated drawworks are improved safety, optimum performance and control, and high reliability. The drawworks package is delivered complete with all necessary hydraulics, lubrication systems, cooling systems, instrumentation and controls and is fully operational from a remote location. The following are the essential functions of the Wirth heave compensated drawworks: n Normal operation to raise and lower the drill string, liner and casing assembliesn Heave compensation function during fixed-to-bottom operationsn Hoisting and lowering functions when facilitating disconnection from well

The Wirth heave compensated drawworks control system is designed with an anti-collision system as an integral part of the control system to prevent the main hoisting equipment (travelling block or top drive) from being run into the crown block or drill floor, as operating conditions may be as follows:

n Hoisting/lowering and related operations are automatedn The speed of the operation involved is too high for the operator to react in timen The driller and other personnel operating the systems do not have an adequate overview of the operation from the operating station The Wirth heave compensated drawworks is equipped with the required system condition monitoring system which is available on the drilling console to facilitate detection of abnormal conditions which may lead to critical malfunctions. Alarms are triggered in the event of abnormal conditions arising. These alarms include: n Anti-collisionn Slack-wire detectionn Failure in the hoisting systemn Fluid systems: temperature, flow and leveln UPS status and charge condition of batteriesn Primary power supply statusn Activation of emergency stop

Wirth active heave compensated drawworks

The AC powered Wirth heave compensated drawworks are based on the conventional single gear system and offer a design unique to the industry, available in a range from 4 500 hp to 13 000 hp.

This type of drawworks combines a modularized design with few mechanical parts, a small footprint and a light weight. A further advantage is the minimized maintenance work.

The Wirth gear-driven drawworks package consists of the following items: main frame, hoisting drum with Lebus system for any wireline size, compound gearbox, drive motors, disc brake, optional Eddy Current Brake. It is completely equipped with all necessary hydraulics, lubrication, cooling, instrumentation and controls. The drawworks will be fully operational from a remote location.

two independent disc brake systems to achieve maximum safety. In the event of a reduction or loss of braking force of the master brake, the second brake system will engage accordingly to compensate for the loss. Thus permitting full and continual operation of the drawworks until remedial work can be performed on the master brake.

Control of the drawworks disc brake, gear selection and operation of the auxiliary drives are controlled by the programmable logic controller (PLC) within the drawworks interface control system (DICS). Braking requirements are determined by the ZPS programmable logic controller which obtains information from the drawworks sensors, the “DCS” and the “VFD”.

The ZPS PLC algorithm calculates the degree of braking required and transmits the relevant signals to the braking systems (“VFD” and “ECB”). The main regenerative braking system is the primary braking system. It is supplemented by the eddy current brake if necessary. The third braking system operates in combination with the primary and secondary braking systems.

Wirth multi/two-gear drawworks – braking systems

The drawworks in our standard configuration includes independent braking systems.

Primary active braking system:The drawworks main drive motors, supplied by Aker Solutions, not only have a driving function but are also used for regenerative braking. For braking, the drawworks motors will operate in generator mode and feedback 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.

Secondary active braking system:The second braking system is an Eddy current brake, which is a dynamic electromagnetic braking devicee. This brake is a high energy absorption device thus maintaining appropriate braking torque at higher drawworks speeds. Under low-speed or nospeed conditions the eddy current brake can only produce low or no braking torque. Under these conditions the regenerative brake takes on most of the load. The eddy current braking energy is dis- sipated by water cooling.

Emergency and parking brake system: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.

Under normal operation conditions the callipers are only applied for parking, holding the load in a static condition and thus preventing its uninten- tional lowering or raising.

Wirth offhore multi and two gear drawworks are equipped with the Wirth Dual Brake System (DBS) which is an intelligent redundant PLC controlled system incorporating

All offhore Wirth single gear drawworks for mid- and deepwater application are equipped with two redundant PLC controlled disk brakes to achieve maximum safety. In the event of a reduction or loss of braking force of the master brake, the second brake will engage accordingly to compensate for the loss. Thus permitting full and continual operation of the drawworks until remedial work can be performed on the master brake.

The drawworks in our standard configuration includes independent braking systems.


Drawworks – control systems

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.

Your benefits:n Single interface for all communication partnersn Full drawworks control of all mechanical functionsn Simple integration into any HMI systemn Communication protocols: Profibus DP, S7, Ethernet

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 state-of-the-art PLC of the Wirth ZPS is based on fail-safe hardware components. This design is suitable for fulfilling the requirements of SIL 3.

Your benefits:n Safe and collision-free movement of the travelling blockn Protection against personal injury and damage to drilling equipmentn Auto-correlation of the brake capacity and the hook load (kinetic energy monitoring)n Fail-safe designn Easy retrofit; integration of existing protection systemsn Work point positioning to ease drilling operation

The integrated auto-driller as an independent system confirms redundancy to the main drive system.

n AC frequency controlled independent drive arrangementn Maximized drilling efficiencyn Automatic drilling operationn Minimized downtimen Smooth block control

The capability to build in an auto-driller is easily given by adding an extra AC drive arrangement, independent 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.

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.

Your benefits:n Continuous, automatic weight-on-bit, DDM torque, rate of penetration or pump pressure controln Emergency lifting and lowering capacityn Easy operation with simple handlingn Complete monitoring of the drilling processn Enhanced safety and equipment protectionn Maximised drilling efficiencyn Automatic drilling operationn Minimized downtimen Smooth block control

This unique system smoothes emergency stops. It avoids bird’s nest effects, thereby optimising protection for personnel and equipment.

The system controls the speed and load of the drawworks drum and the attached wireline. Depending on load and speed, WPS will smooth sudden stops to prevent the bird’s nest effect due to the installation of a combined hydraulic-electronic system controlled by the PLC.

Your benefits:n Protects your drawworks against the bird´s nest effectn Smoothes emergency stops during hoisting operationsn Fail-safe systemn Reduces downtime and equipment damage to save costsn Extends the wireline lifetimen Increases availabilityn Optimises number of roundtripsn Easy to retrofit on existing Wirth drawworks
