The core applications requiring grease in the Offshore industry include: electric motor bearings, general bearings, open gears, wire ropes, jacking and skidding.
The fundamentals for product selection are compatibility, base oil viscosity, method of application, re-lubrication frequency and re-lubrication quantity. A comprehensive range of Castrol greases is available for offshore applications.
Castrol Speerol SY1002 is a lithium complex No.2 thickened lubricating grease based on synthetic base oil. The grease contains antioxidants, corrosion inhibitors and Extreme Pressure / Anti Wear additives.

Castrol Tribol 4747 high-temperature synthetic grease enhanced with lithium complex thickener, corrosion inhibitors and antioxidants is a clear multi-service lubricant designed to extend the service life of rolling and sliding bearings in heavy-duty applications and at elevated temperatures. Because of the high base oil viscosity Castrol Tribol 4747 provides a heavier oil film for applications at slower speeds, higher loads and/or higher temperatures resulting in excellent protection against friction and wear. Castrol Tribol 4747 grease is also suitable for use when loads are moderate to heavy and speeds are slow to moderate.
MOLUB-ALLOY 860-460 2ES
Castrol Molub-Alloy™ 860 ES greases are high-performance multi-service lithium complex greases formulated from premium petroleum base oils, lubricating solids and a combination of corrosion inhibitors specifically chosen for protection against corrosive process waters. These are designed to extend the service life of bearings in heavy-duty applications at elevated temperatures sustained for long period of time, at slower to moderate speeds and higher loads.
MOLUB-ALLOY 936 SF HEAVY
Castrol Molub Alloy 936 SF Heavy Open Gear Grease is an advanced solvent-free lubricant developed specifically for heavily loaded open gears and jacking racks on all types of heavy duty equipment on Offshore and Onshore assets. The range is compounded to give maximum protection to mobile and fixed equipment while helping to minimise potential pollution to the marine environment. It forms a tough lubricating film on the friction surfaces which is resistant to pressure and shock loads as well as unfavourable ambient conditions.
MOLUB-ALLOY 6040/460-1 1/2
Castrol Molub Alloy 6040/460-1 1/2 is calcium complex highly water resistant EP grease. High performance multi-purpose grease for use in plain, antifriction bearings. The extreme pressure properties are most evident in application with frequesnt start-up, slow speeds or where high or unexpected loads take place. Particularly suited as a curved tooth couplings grease for offshore applications transmitting high horse power.
Molub-Alloy 777-2 ES
Castrol Molub-Alloy 777-2ES series are multipurpose greases designed for very heavy duty service at slow speeds in adverse environments. These greases operate effectively in plain bearings, journals, and in antifriction bearings other than precision and high speed. They exhibit excellent adhesive and cohesive characteristics and, yet, are highly resistant to mechanical shearing.Primary applications Offshore are FPSO turret bearings (Bucyrus approved), ball and roller bearings, bushings, slides, screws.
Castrol Tribol 3020/1000 lithium greases with TGOA were designed for very heavy duty service in adverse environments. Through their formulation and advanced TGOA additive system, they are able to withstand the shock and heavy loading commonly found in the processing of primary metals as well as in cement, construction, and mining industries. Primary application offshore is curved tooth couplings on thruster packages, however can be used in gearboxes which are not oil tight and heavily loaded rolling and sliding bearings.
Castrol BioTac OG is a high performance environmentally responsible OSPAR compliant open gear grease with no substitutable components. All the components of Castrol BioTac OG have been selected for their low environmental impact, either from the PLONOR* list of chemicals or following a thorough assessment of their biodegradability, potential for bioaccumulation and their toxicity towards marine species. It is highly resistant to water wash-off and provides excellent corrosion protection. The grease is used Offshore in rack and pinion gearing on the legs of jack-up drilling rigs where high load carrying performance of the grease helps minimise wear on pinion teeth and guides. *PLONOR – Pose Little or No Risk to the Environment (OSPAR definition)
High Temp Grease
High Temperature No.2 Lithium complex grease is a high performance multi-purpose grease , suitable for use across a wide range of operating temperatures, extreme pressure and a variety of speeds. The grease is formulated to be used in general plain and rolling bearings, slides and bushes, onshore and offshore installations where greater extremes of pressure and temperature may be prevalent.
Spheerol AP2 & AP3
Spheerol AP 2 and AP 3 are lithium-based greases incorporating solvent-refined base oils. Both greases contain oxidation and corrosion inhibitors, which help to ensure long service life and a high level of protection for metal surfaces. The greases are water-resistant. Spheerol AP 2 and AP 3 are mainly intended for use in plain and roller bearings of all types and in all kinds of machinery under normal load conditions. . Spheerol AP3 is particularly suitable for use as electric motor grease.
Castrol Spheerol LMM is a multi-purpose lithium base grease . manufactured to close control of drop point, penetration number, alkalinity and ash content to offer high stability, long life, excellent resistance to changes in consistency and good water-proof quality. Spheerol LMM grease mainly used in plain and rolling element bearings subjected to heavy loads and excessive vibrations, at low and medium speeds. The incorporation of solid lubricant in Spheerol LMM grease makes it particularly suited for the lubrication of reciprocating and sliding motion elements, chains, swivels and shackles, flexible joints, where the prevention of scuffing and fretting is desirable.
Spheerol EPL RANGE
Castrol Spheerol EPL range of greases are lithium 12-hydroxy base products designed with high quality refined mineral base oils and fortified with extreme pressure (EP) additives as well as corrosion and oxidation inhibitors. These greases have been formulated with a special EP package that provides high film strength under high loads and shock loadings.
Spheerol SX2 is a calcium complex sulphonate grease providing superior performance benefits in the highly aggressive conditions experienced in the marine environment: resistant to both fresh and salt water providing a high level of corrosion protection. Spheerol SX 2 is a multipurpose lubricant specifically developed to provide enhanced lubrication and protection for bearings, wire ropes and open gears found usually in Offshore environments. Always check your equipment manual and consult with a Castrol Technical Service Engineer to choose the right product for the right application.
