Seafloor Drill Rig

Seafloor Drill Rig HD-500 is specially designed for marine geological exploration. It is suitable for various high efficiency drilling techniques such as diamond wireline coring, wave compensation directional drilling, continuous circulation coring and so on. The main body includes power system, hydraulic control system, drill rig components, power head feeding, hoisting winch, pull-up casing winch, wireline coring winch, hoist impact, power head, energy storage, mud transmission and blender system. Energy switching can be conducted easily at customers' will in accordance to the conditions at the construction site.

• Adopts modular design and therefore can be detached or installed easily. It has strong drilling ability and high reliability.
• The rig has a self-made 4-speed gearbox. It has high strength and easy for maintenance. Besides, it has wide range of speeds and can be manipulated continuously between 0-1200. In addition, it has large torque which is beneficial to the speed selection for various drilling processes involving diamond drilling as the main body.
• It has spindle stroke of 6.5 meters which is beneficial in increasing the drilling efficiency. Fully equipped meters which allows visualizing and monitoring of parameters such as torque, pressure, oil temperature, power system and so on. Thus, the working process and drilling conditions of the equipment can be mastered to prevent as well as reducing the drilling accidents.
• Key components such as hydraulic pump, motor, winch and main hydraulic components are from international well-know brand. The equipment has strong reliability. It has high standardization and generalization which is convenient for maintenance and cost saving.
• The hydraulic system adopts the reliable new structure seals, hydraulically driven mud pump and mud agitator. Therefore, the drilling process does not require other auxiliary power.
