      Promulgator ：keler      Time：2016-02-24
Sham major national scientific and technological research projects focus on new products to fill the gaps in the field of marine engineering equipment of deep-sea exploration.


Ø advanced all-digital AC frequency conversion control technology, intelligent driller rig operations.


Ø using self-developed affordable hook load, wind load and hull derrick swing and other dynamic to dynamic loads, the ability to adapt to strong sea conditions.


Ø Tour models use active heave compensation means drillstring and compensation winch, safe and reliable operation.


Ø use of wireless remote control and battery-powered submarine base plate, to achieve power transmission, deck space and cost savings.


Ø using pipe processing apparatus to realize the drill string stacked enhance mechanized operations.
