High-durability lubricants engineered for dynamic sea environments, anti-corrosive power transmission systems, and offshore rig diesel gensets.
The search for offshore energy reserves has pushed drilling operations into ever-deeper waters, exposing equipment to some of the most hostile environments on Earth. Modern marine drilling units, jack-up rigs, and Floating Production Storage and Offloading (FPSO) vessels operate under relentless conditions characterized by extreme hydrostatic pressure, heavy mechanical friction, saltwater-induced oxidation, and wide temperature swings.
In these high-stakes commercial operations, equipment failure is not just an inconvenience—it translates directly to catastrophic downtime costs, severe safety risks, and potential environmental liabilities. Offshore lubricating solutions must act as more than just a barrier between moving metals; they are integral components of structural preservation and operational runtime optimization.
Marine atmospheric environments are saturated with chloride ions, which rapidly accelerate pitting corrosion on metal contacts. Furthermore, the massive mechanical stress placed on top drives, mud pumps, and subsea drawworks shears standard polymer viscosity index improvers. Once sheared, the oil drops in viscosity, leading to boundary lubrication where metal-on-metal contact occurs. To survive these parameters, wholesale offshore oil exporters must supply lubricants that balance high-temperature shear stability (HTHS) with low-temperature fluid flow for subsea piping deployment.
A high-tech pioneer integrating R&D, advanced blending processes, and global logistics since 2009.
Established in 2009 and headquartered in the industrial hub of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has spent over 15 years engineering high-performance lubricants. As a trusted partner for heavy-duty industrial and maritime clients worldwide, the company manages the full lifecycle of lubrication development from fundamental lab-scale chemical synthesis to high-capacity fully automated packaging.
Longhai proudly manufactures its proprietary brand "Century Longhai" alongside the internationally recognized, strategically aligned British "A Ba" series. Our comprehensive catalog ranges from diesel and gasoline engine oils, industrial gear oils, and anti-wear hydraulic fluids, to highly specialized marine transmission oils, anti-freeze, and automotive urea solutions. Protecting our clients’ long-term investments, all core product lines are fully backed by product quality liability insurance underwritten by the PICC (People's Insurance Company of China).
Offshore drilling structures are complex, distributed engineering environments. Each segment requires specialized chemical formulations to assure reliability and compliance with maritime environmental laws.
Offshore drawworks deploy massive tension systems to hoist and lower drill strings. They rely on high-performance industrial gear oils (such as China L-CKC and L-CKD heavy-duty gear oil) to prevent gear tooth spalling under high shocks. Our formulations contain active sulfur-phosphorus EP (extreme pressure) additives that react at high temperatures to form a resilient protective boundary layer.
The BOP stack represents the ultimate safety barrier against high-pressure gas kicks. The hydraulic fluid operating these systems must transfer power instantly without compressible bubbles. Longhai's anti-wear hydraulic oil features superior air-release properties and high shear stability indexes, assuring quick BOP actuation when safety tolerances are breached.
Offshore installations operate self-contained mini-grids powered by massive dual-fuel turbines or diesel gensets running continuous cycles. Turbine lubricating systems demand extreme oxidative resistance to avoid varnish formation. Longhai's wholesale turbine oil is formulated with high-purity base oils and advanced oxidation inhibitors, extending oil life and preserving bearing integrity.
Operating under rigorous global frameworks to ensure reliable deliveries to major ports and offshore platforms.
Longhai Technology operates a state-of-the-art 131-acre manufacturing center equipped with precision blending lines. Our filling lines utilize metering mechanisms that guarantee volumetric accuracy of 1‰ to 2‰ while increasing production speeds by 20% to 35%.
To serve international offshore projects, compliance with rigorous standards is non-negotiable. Our manufacturing site and internal control laboratories operate in full alignment with international quality structures:
Our operations are certified under ISO 9001:2015 (Quality Management System), ISO 14001:2015 (Environmental Management System), and ISO 45001:2018 (Occupational Health & Safety Management System). Furthermore, our premium automatic transmission fluids carry direct approvals from Mercedes-Benz, proving our capacity to satisfy the strict lubrication parameters set by the world’s leading engineering OEMs.
Custom chemical engineering to meet unique environmental pressures, regional compliance codes, and specific machinery profiles.
We modify viscosity indexes, pour points, and add specialized rust inhibitors to create tailored lubricants that comply with demanding API, ACEA, and marine OEM specifications.
We offer diverse packaging formats optimized for offshore logistics, ranging from industrial-grade intermediate bulk containers (IBC totes) to heavy-gauge steel drums designed to handle maritime transport.
Every product batch is accompanied by comprehensive laboratory test reports (including ASTM-compliant testing for viscosity, total base number, and water separation speed) ensuring consistent quality.
Evaluation of machinery, operating temperatures, moisture exposure, and local regulatory laws.
Developing custom chemical blends in our state-of-the-art testing laboratories.
Simulating extreme pressure and marine environments to verify performance benchmarks.
Precision automated blending, safe container filling, and robust packaging for global export.
Post-delivery analysis, oil life monitoring, and ongoing logistical support.
Modern offshore drilling operations face increasingly strict environmental regulations. Under the United States Environmental Protection Agency’s (EPA) Vessel General Permit (VGP) and international OSPAR commission directives, equipment interfaces exposed to ocean water must use Environmentally Acceptable Lubricants (EALs). These regulations affect thrusters, controllable pitch propellers, stabilizers, and subsea deck equipment.
Traditional mineral oil-based lubricants present high toxicity risks and persist in marine ecosystems in the event of an accidental spill. To address these concerns, our R&D roadmap focuses on developing advanced synthetic ester and polyalkylene glycol (PAG) base oils. These synthetic matrices provide:
Formulated to degrade rapidly in aquatic environments, reducing toxic bio-accumulation in marine food chains.
Utilizes advanced zinc-free anti-wear agents to minimize chemical damage to delicate marine organisms.
Synthetic bases naturally resist oxidation, reducing oil replacement cycles and lowering operational waste.
By transitioning to advanced synthetics, offshore drilling operators can easily comply with international environmental frameworks while maintaining the load-carrying capacity and wear protection required by heavy-duty offshore equipment.
