Electrified retrofit
Mechanical drilling rigs adopt electric drive instead of diesel-engine drive, to raise efficiency and reliability, reduce drilling cost, and reduce pollution. The catalog applies this retrofit to rigs such as the 40LDB, 50LDB, and 70LDB.

System features
- Flexible configuration matched to equipment already on the rig, to meet the rig's power requirement
- Variable-frequency motor drive, with little effect on the grid and a wide speed range
- Remote diagnosis of on-site faults
- Remote monitoring of operating parameters
Case captions for this work, including Indonesia 1500HP and a Sinopec mechanical-rig retrofit, are on where the systems run.
Direct-drive and permanent-magnet motor rows printed on the same spread are on drilling motors.
