Power unit and Mast drive type of Storm drilling rig
The modular design principle of the Storm drilling equipment allows for the selection of all key components that make up the drilling rig, starting with the power unit and the mast drive type.
The primary component of the power unit is an internal combustion engine. There are two types of internal combustion engines available for the Storm drilling equipment. The first option is a more powerful diesel engine with water cooling. The second option is a gasoline engine with air cooling. Below are the main characteristics of the diesel and gasoline engines.
