Aker SolutionsDrilling TechnologiesTop drivesTop drivesAker Solutions delivers reliable and flexible top drivesolutions. Since 1982, our top drives have been indaily operations around the world. Our systems aredesigned for rough conditions and comply with thestrictest approvals for the drilling industry. We providesolutions ranging from portable land rig applications toextreme deep water applications.MotorsAC, DC and hydraulic motors are offered. All our drivemotors are designed specifically for optimum variablespeed performance and certified for operation inhazardous area.Gear boxesThe top drives are equipped with high quality gearboxes. We use the highest quality selection of gearsand bearings to maximise machine uptime.Pipe handlersThe top drives include a remote controlled,multifunctional pipe handler. Pipe handlers can rotatefreely, and are equipped with automatic positioningto ensure safe, easy and accurate orientation. Ourknuckle link pipe handler is a well proven design withunique handling capabilities.Efficient directional drillingStandard AC top drives include tool face orientationsystem for controlling the direction of the down-holemotor. Accuracy of the deviation is easily maintained,as the direction only has to be adjusted every 90 ft(27 m).Control system and operator interfacesThe top drives are delivered with MH control systemfor optimal operation and lifecycle support. We delivera range of different equipment/solutions for operatorenvironments, from the simplest stainless steelpanels to the state-of-the-art MH DrillView operatorenvironment. We also deliver interfaces to third partyoperator systems.VFD/AC drivesOur standard delivery is ABB drives. We can alsodeliver interfaces to other drive types on request.> MH DDM 1000AC

Aker SolutionsDrilling TechnologiesTop drivesGame-changing modulartop driveAker Solutions delivers the MH modular derrickdrilling machine (MDDM) to advanced drill ships.This innovative technology gives maximum uptime,extreme performance and enhanced safety.Characteristics• The MDDM is designed to support toughrequirements, including a 99.9% uptime. This is atrue sixth generation top drive• The design is based on a downtime analysis of 72top drives from vendors over a five years period• Modular design and extensive use of quickconnectors improve maintenance and reduce theimpact on the critical path of the operation• Significantly improved main bearing design thatis based on actual measurements from high-enddeepwater rigsInnovative cooperationOffshore drilling contractor Transocean and AkerSolutions have designed a radically improved derrickdrilling machine that provides enhanced safety,efficiency and drilling uptime. The companies haveput considerable effort into identifying the currentand future limitations of available top drives and therelated design and components.Modular design improves uptimeTo offer the most-advanced capabilities in the offshoredrilling industry, the MDDM is designed to achievesavings through downtime prevention, reducing repairtime from days to a few hours. The modular designallows for quick replacement and repair of modules.Other savings include reducing out-of-service time foroverhauls and annual load path inspections, whichcan be done offline or during a rig move.Novel design principlesIn addition to the benefits of its modularity, the MDDMis based on novel design principles and factualoperational data resulting in superior quality design ofcritical components such as bearings, main shaft andmotors.A change in industryIn recent years top drives have been taken to theiroperational limits by increasingly aggressive wellprograms. As a result, top drives now have higherfailures rates, because they are working harder andwearing faster than ever before. The MDDM will playa pivotal role for clients’ efforts to overcome thesechallenges.Main benefitsThe MDDM enables rig operators to expand thesearch for new sources of energy while obtainingmaximum uptime, extreme performance andenhanced safety.> MH MDDM 1000AC
