Propulsion equipment lubricants

In the offshore sector Castrol BioStat protects marine thrusters, stern tubes, spur, planetary or helical gear units or rolling and sliding bearings. It is resistant to breakdown by hydrolytic, thermal or oxidative mechanisms and is biodegradable in the marine environment. It has reduced potential for bioaccumulation and low toxicity to marine organisms should it enter the sea.

The Alpha SP gear oils is a range of high quality mineral lubricants enhanced with sulfur/phosphorus extreme pressure additive technology, providing outstanding thermal stability and high load carrying capacity. The range is particularly suitable for use in thrusters and pitch control in offshore applications.

Suitable for thruster steering and retractor systems, these premium high viscosity mineral oils are enhanced with anti-wear and anti-corrosion additives and a shear-stable viscosity index improver to help maintain viscosity over a wide temperature range. It has excellent hydrolytic stability and separates rapidly from water contamination.

Castrol Molub-Alloy 6040/460-1 1/2 is calcium complex highly water resistant multi-purpose EP grease. It suits applications with frequent start-up, slow speeds or where high or unexpected loads take place and works well as a curved tooth couplings grease for offshore applications transmitting high horse power.

This lithium-based grease incorporates solvent-refined base oils. It is water resistant and contains oxidation and corrosion inhibitors that offer a high level of protection for metal surfaces. Primarily intended for use in plain and roller bearings of all types, in all kinds of machinery under normal load conditions, Spheerol AP3 is suitable as electric motor grease.

This calcium complex sulfonate grease performs well in the marine environment. It provides a high level of corrosion protection and resistance to both fresh and salt water. Spheerol SX2 is a multi-purpose lubricant that gives enhanced lubrication and protection for bearings, wire ropes and open gears found in offshore environments. In propulsion applications is used for void spaces (hubs) and general greasing.

Castrol Tribol 3020/1000 lithium greases with TGOA are designed for heavy duty service in adverse environments, like those found in primary metals processing and cement, construction, and mining industries. Offshore applications include curved tooth couplings on thruster packages, and can be used in non-oil tight gearboxes and heavily loaded rolling and sliding bearings.
