Industrial grade formulations engineered for extreme mechanical stresses, thermal variance, and heavy machinery protection
The global offshore oil rig industry sits at the apex of ocean engineering, necessitating structural endurance under the most punishing atmospheric and marine conditions. As energy extraction moves into ultra-deepwater plays, drilling structures—including jack-ups, semi-submersible rigs, and Floating Production Storage and Offloading (FPSO) units—must withstand hyperbaric pressures, salt spray corrosion, and continuous mechanical loading. At this scale of industrial deployment, downtime is measured in millions of dollars per day, rendering the mechanical reliability of all moving components a mission-critical priority.
In this ecosystem, high-performance lubricating fluids act as the structural buffer. Heavy-duty offshore oil rigs require sophisticated anti-wear hydraulic oils, high-pressure gear lubricants, and robust turbine fluids to run their drawworks, top drives, cranes, and anchoring thrusters. Without these specialized fluids, the massive structures built by leading manufacturers cannot survive the harsh ocean elements.
China has transformed into the world's primary hub for high-end maritime equipment engineering. This structural ascent is powered by massive factory supply chain integration, steel manufacturing leadership, and the presence of dedicated lubrication pioneers like Shandong Longhai Lubrication Technology Development Co., Ltd.. Leveraging close proximity to raw material producers, advanced synthesis technologies, and streamlined port logistics, Chinese manufacturers deliver cost efficiencies and high-velocity shipping schedules that global competitors struggle to match.
Shandong Longhai Lubrication Technology Development Co., Ltd. was established in 2009 and is headquartered in Zibo, Shandong. It is a high-tech enterprise integrating R&D, production and sales. The company has been deeply involved in the lubricant industry for more than 15 years, has built a complete industrial chain system, and is committed to providing high-quality lubrication solutions for the global industrial and transportation fields.

The brand is insured by PICC China People's Insurance Company and quality insurance.
Ensuring operational reliability under extreme stress conditions with state-of-the-art production systems
Our filling production line adopts the principle of metering filling, which is suitable for filling various lubricating oils and ensures the filling accuracy of 1‰-2‰. While ensuring accuracy, it increases the filling speed by 20%-35%, effectively increasing industrial throughput.
Longhai Technology has always insisted on innovation-driven development. Our annual R&D investment accounts for more than 5% of total revenue. We have established strategic partnerships with universities and research institutions to continuously optimize lubrication technology.
Our expansive production base covers an area of 131 acres, with an annual production capacity of 200,000 tons. It is fully equipped with intelligent production lines and precision laboratories to satisfy custom technical needs from global oilfield operators.
Quality reliability and environmental stewardship are the structural cornerstones of our heavy industrial lubricants operations. Shandong Longhai Lubrication Technology has systematically validated its operational protocols through comprehensive certifications.
The company has passed ISO-9001-2015 quality system certification, ISO 14001 environmental management system certification, and ISO 18001 health management system certification. Furthermore, our automatic transmission lubricants have successfully secured the prestigious Mercedes-Benz certification, laying a robust foundation for product stability and global export safety compliance. The company strictly follows international standards and introduces foreign production processes and testing technologies to ensure that the products can still perform excellently under extreme working conditions, helping customers improve equipment efficiency and reduce maintenance costs.
Tailored lubrication performance designed specifically for heavy equipment operators and harsh marine environments
Offshore oil rigs require absolute hydraulic pressure consistency under ocean depths. Our premium anti-wear hydraulic oil prevents fluid shear, maintains viscosity under sub-zero temperatures, and protects deepwater drilling machinery from sudden high-pressure surges.
For land transport networks feeding components to ports and manufacturing plants, our CI-4 Plus and CF-4 heavy-duty diesel engine oils provide exceptional soot control, reducing wear and keeping heavy trucks operating efficiently over long distances.
Offshore generator stations and steam turbines operating on support vessels require rapid heat dissipation and water-separation properties. Longhai turbine oil provides a highly stable oil film, preventing rust under high humidity and salty offshore atmospheres.

Highly stabilized formulations for transmission, gear, hydraulic, and process machinery operations
Expert insights regarding industrial lubrication performance, maritime asset integrity, and supplier logistics
Offshore oil rig mechanisms, including top drives, crane hydraulics, and thrusters, operate continuously in environments characterized by high salinity, moisture, and extreme temperature variations. Standard lubricants degrade rapidly in these settings, leading to varnish formation, component rust, and mechanical failure. Utilizing high-specification industrial fluids, such as Longhai Anti-Wear Hydraulic Oil and L-CKD Heavy-Duty Industrial Gear Oil, ensures stable oil film protection, prevents oxidation, and keeps maintenance intervals to a minimum.
Our intelligent filling lines employ high-precision flowmeters and mass-balance metrics, securing a filling accuracy between 1‰ and 2‰. By standardizing manufacturing sequences, we protect batch consistency while improving processing speed by 20% to 35%. Every batch undergoes rigorous quality assurance checking in our dedicated, on-site laboratories before containerization.
