TOP DRIVES
Electric Top Drives
Hydraulic Top Drives
Top drives technology has gradually become almost the norm and standard in most drilling operations in the oil and gas industry today. The reason for this choice is not far-fetched, increased safety and performance is the major drive for the use of top drives. At Drillmec, we have over thirty years of experience in designing and producing top drives.
We offer mainly two classes of top drive which are the Hydraulic Series (HTD) and the Electric Series (ETD). We design portable top drives with permanent installation for both offshore and onshore drilling processes.
Our top drives are specially designed for easy integration with various mast designs and support both directional and horizontal drilling processes while delivering high performance and safety. Our standard top drives feature all the key elements of top drives such as standard washpipe, hanger assembly, link-tilt-system, remote-controlled and manual IBOP, and many others.
Electric Top Drives Series (ETD Series)
We design electric top drive that is transportable, permanently mounted on different mast configurations for deep drilling rigs. Some of the features include:
• AC motor powers the system
• Separate control panel controls system
• Maximum speed range of between 200 rpm to 219 rpm
• Power rating range of between 450 kW (600 hp) to 850 kW (1150 hp)
• Maximum drilling torque range of between 43,200 Nm (31,662 lb/sqft) to 80,000 NM (59,000 lb/sqft)
•Maximum pull up static load of between 245 mt (550,000 lbs) to 680 mt (1,500,000 lbs)
Hydraulic Top Drives Series (HTD Series)
Our hydraulic top drive series are designed to deliver high performance, can be fitted to almost any mast design available. It has the following features:
• Maximum speed range of between 180 rpm to 190 rpm
• Power rating range of between 403 kW (5340 hp) to 470 kW (630 hp)
• Maximum drilling torque range of between 36,000 Nm (28,765 lb/sqft) to 53,000 Nm (39,090 lb/sqft)
• Maximum pull up static load of 226 mt (500,000 lbs) to 317 mt (700,000 lbs)
