Game-changing modular derrick drilling machine

Aker Solutions designs and delivers modular derrick drilling machines (MDDMs) to advanced drillships. The innovative technology of the MDDM gives maximum up-time, extreme performance, enhanced safety and improved efficiency.


The company has put considerable effort into identifying the current and future limitations of available top drives and the related design and components. The result is Aker Solutions' modular derrick drilling machine, the MH MDDM 1000 AC™. 

The MH MDDM 1000 AC™ is designed to achieve savings through downtime prevention by reducing repair time from days to only a few hours, thus offering the most advanced capabilities in the offshore drilling industry. Other benefits include reducing out-of-service time for overhauls and annual load path inspections, which can be done offline or during a rig move.

Aker Solutions maintains that the unit will play a pivotal role in clients’ increasingly aggressive well programs. In recent years these programs have take top drives to their operational limits. As a result, top drives now have higher failures rates, because they are working harder and wearing faster than ever before.

In addition to the benefits of its modularity, the MH MDDM 1000 AC™ is based on novel design principles and factual operational data resulting in superior quality design of critical components such as bearings, main shaft and motors.

The MH MDDM 1000 AC™ enables rig operators to expand the search for new sources of energy while obtaining maximum up-time, extreme performance, enhanced safety and improved efficiency.

Characteristics

  • The MH MDDM 1000 AC™ design is based on the analysis of downtime of 72 top drives from vendors over a five years period.
  • Modular design allows for replacing individual modules, thus reducing its impact on the critical path of the operation.
  • Significantly improved main bearing design based on actual measurements from high-end deepwater rigs .
  • Extensive use of mechanical, hydraulic and electrical quick connectors reduces time to repair.
  • Designed to support tough requirements, including a 99.9% uptime. This is a true 6th generation top drive.
