Huizhi Holdings is a backbone enterprise of manufacturing offshore oil drilling and production equipment in China. Based on strong R&D and manufacturing capability of onshore oil drilling and production equipment, Huizhi Holdings has entered the field of offshore engineering equipment since the early 2020s, and has maintained leading advantages in technology and performance in offshore fixed platform drilling rig. offshore cementing & fracturing equipment, offshore manifold products. The products of the National Technology Innovation Excellent Project Award are distributed in the Bohai Sea, the East China Sea and the South China Sea, and exported to the international market. Four fixed platform drilling rigs have been operating in China's Bohai Sea, and exported to the United States, Malaysia and other countries. Huizhi Holdings has accumulated technological knowledge to build 9000m jack-up offshore platform drilling package and 25000hp offshore fracturing vessel.
Fixed platform drilling rig, lightweight offshore drilling rig
•Optimized module design. 30% lighter than the same type of offshore drilling rig.
•It adopts bootstrapped mast. and can choose main drawworks or hydraulic winch for installation, which is suitable for offshore installation and maintenance.
Power drives include diesel engine, DC/AC frequency conversion,d hydraulic, hybrid drive, etc.
•Symmetrical arrangement for easy maintenance and high safety redundancy drawworks for offshore rigs.
Guylineless double section mast with telescopic cylinder for easy installation, maintenance and avoidance of drilling vessels in the sea.
• The whole area of toxic and combustible gas monitoring and alarm system, the rig has explosion-proof design to ensure safety.
• The substructure has fully enclosed sewage collection structure. It is green and environmentally friendly.
Fixed platform workover rig
• The upper and lower sliding double-layer substructure which can slide up and down can be longitudinally and horizontally sliding to each wellhead of the cluster well, and the top drive can be installed.
• Power drives include diesel engine. DC/AC frequency conversion,d hydraulic, hybrid drive, etc.
• Guylineless double section mast with telescopic cylinder for easy installation, maintenance and avoidance of drilling vessels in the sea.
• Module design is easy to lift.Lightweight and excellent capability.
• The structural parts are treated with marine anticorrosive technology such as spraying aluminum and hot dip galvanizing.
Removable offshore workover rig
• Platform crane can be used for mobilization, no need to use floating crane, which can reduce costs and improve equipment utilization,
• Based on the platform crane capacity, the maximum lifting module can be designed up t 8T-30T.
• Easy-to-relocate modular structure, the relocation cycle can be controlled within 20 days
