420k Hydraulic Drilling Unit

420k HYDRAULIC DRILLING UNIT

The reliable and flexible 420K HDU /HWO Unit has been designed for side track drilling and workover operations offshore. The 420k satisfies your need for high quality, safe and efficient operations.

The pipe is lifted by a cable /pulley system which is powered by three vertical positioned hydraulic cylinders. The rig is capable of racking “doubles”. The mast is self-erecting allowing the rig to work on small platforms with limited crane capacity. The sub-frame enables to skid the rig from well to well efficiently. The footprint of the rig is reduced by integrating tanks and other equipment in the sub frame of the rig.
