Offshore Equipment

SJ is a backbone enterprise of manufacturing offshore oil drlling and production equipment in China. Based onstrong R&D and manufacturing capability of onshore oil drilling and production equipment, SJ has entered thefield of offshore engineering equipment since the early 1990s, and has maintained leading advantages intechnology 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 aredistributed in the Bohai Sea, the East China Sea and the South China Sea, and exported to the internationalmarket. Four fixed platform drilling rigs have been operating in China's Bohai Sea, and exported to the UnitedStates, Malaysia and other countries. SJ has accumulated technological knowledge to build 900om jack-upoffshore platform drilling package and 25000hp offshore fracturing vessel.

Other products include coiled tubing units, snubbing units, drawworks, masts, crown blocks and traveling blocks, swivels, rotary tables, mud pumps, and high-pressure manifolds.

Applications

SJ offshore equipment serves the full spectrum of marine oil & gas development:

• Fixed platform drilling & workover – Modular drilling systems designed for platform integration with minimal footprint

• Jack-up rig applications – Compact, high-performance equipment optimized for self-elevating units

• FPSO / FLNG support equipment – Production stimulation, cementing and fracturing packages for floating production systems

• Shallow water, deepwater & ultra-deepwater projects – Custom-engineered solutions for any water depth

• Subsea production support – HPHT fluid control products for wellhead and christmas tree applications

• Offshore well intervention – Snubbing units and coiled tubing equipment for live-well operations

Our equipment has been exported and deployed in major oil-producing regions including the Middle East, Africa, and Southeast Asia. Recent deliveries to Kuwait's state oil company mark a breakthrough into the Middle East’s high-end market. Sinopec Oilfield Equipment Corporation has also signed strategic cooperation agreements with ADNOC, sharing technologies and providing equipment support for unconventional oil and gas development.

OEM / Customization Solutions

Not every offshore project follows the same blueprint — and neither do our solutions.

SJ offers full OEM and ODM customization for offshore equipment. Whether you need specific hook load ratings, modified mast heights, specialized fluid control configurations, equipment adapted for unique platform constraints, or pressure ratings beyond standard ranges, our engineering team works alongside your technical staff to deliver equipment that fits your operation like a glove.

What we can customize for you:

• Structural modifications (mast height, substructure design, skidding systems)

• Power system configurations (diesel-electric, AC-VFD, DC)

• Control system integration (Si-driller, third-party automation interfaces)

• HPHT fluid control components (custom pressure ratings, sizes, materials)

• Corrosion protection packages for specific marine environments

• Compliance with classification societies (ABS, DNV, BV, CCS upon request)

With over 2,100 sets of precision equipment, seven dedicated production lines (drawworks, gear boxes, cylinders, masts, high-pressure manifolds, plunger pumps, post-treatment), and three assembly lines, we turn custom specs into delivered hardware.

We also provide on-site inspection, testing, and retrofit services through our third-party accredited inspection subsidiary — meaning we're not just a supplier; we’re a lifecycle partner.
