The beginning of MHWirth dates again to 1895 when drilling pioneer Anton Raky based the “Internationale Bohrgesellschaft Aktiengesellschaft“ (IBG), which quickly had its headquarters in Erkelenz, Germany. Being on the coronary heart of the oil enterprise proper from the start, he laid the inspiration of at present’s MHWirth.
In 1904, the corporate constructed its first mud pump, and since then, greater than 1500 mud pumps in several designs have adopted. MHWirth legacy of drawworks dates again to the 1950s, and in addition is historical past to ship Pyramid masts and substructures for land rigs. In the next many years the agency added piston diaphragm pumps to its portfolio serving the mining trade in addition to pile high drill rigs with Reversed Circulation Drilling (RCD) expertise for the development of basis buildings. That expertise additionally laid the inspiration for a later involvement in subsea mining. At that point, the Germany-based firm was well-known within the trade underneath the identify of “Wirth”.
In the early 1970’s, supporting the oil trade in Norway, Bjarne Skeie pioneered the drilling trade in Kristiansand. He constructed his first crane in 1968 earlier than he established Maritime Hydraulics.
In the 1970’s, France’s CEA, conducting underground nuclear testing on the atoll of Mururoa within the South Pacific, was utilizing a Wirth reverse circulating system to spud its 70 inches holes.
In the 1980s Maritime Hydraulics and Wirth began collaborating in oilfield tasks.
In 1990, MHWirth delivered the primary large-scale drilling rig for De Beers’ diamond mining vessel “Coral Sea”. This improvement laid the inspiration for a strong collaboration between MHWirth and De Beers, the world’s largest diamond firm. Ever since then, MHWirth outfitted 5 drill ships for De Beers to reap diamonds off the coast of Namibia in water depths of as much as 150 m. Continuous system upgrades and optimization throughout operation considerably improved the vessels’ efficiency.
The strategic partnership between De Beers and MHWirth delivered important features within the areas of asset utilization, gear availability and reliability with important enhancements in mining charge.
During mining operation, a MHWirth drill bit with as much as 7.2 m in diameter loosens the fabric from the seabed. The materials is then transported vertically by means of a big diameter airlift drill string (as much as 700 mm in diameter) to the drilling vessel for additional processing. Core of this expertise is MHWirth’s environment friendly and environmentally-friendly reverse circulation expertise, also called airlift expertise. Compared to different options, MHWirth’s airlift expertise makes use of solely strong elements with restricted complexity underneath water, thus maximizing gear availability and optimizing operational prices (OPEX). Thus, MHWirth drilling gear permits the vessels to function even underneath extreme sea situations.
In June 2009 Wirth Maschinen und Bohrgeräte Fabrik GmbH was generally known as Aker Wirth GmbH. This following the acquisition of the corporate by Aker Solutions of Norway. Wirth GmbH grew to become a completely managed subsidiary of Aker Solutions of Norway.
During that point, Aker Wirth constructed its first high drives. In addition to its drawworks portfolio, the award-winning RamRig was launched in 1996; a extremely environment friendly compensating system for semi-submersible and drillship operations.
In 1999 Wirth acquired Paurat, makers of heavy responsibility roadheaders. In 2001 it purchased microtunnelling producer Soltau. In September 2007, it offered its controlling share in its NFM soft-ground TBM division, 70% to China’s state-corporation NHI, Northern Heavy Industry Group and 30% to Niko Kleuters, beforehand a senior government and co-owner of Wirth.
The starting of a brand new period for the corporate began in 2014, when the brand new model “MHWirth” was established, reflecting the 2 robust manufacturers MH (from earlier Maritime Hydraulics) and…
