BIOTAC OG

OSPAR compliant with no substitutable components. US Vessel General Permit 2013 compliant.
Castrol BioTac OG is a highly tenacious, high performance open gear lubricant developed specifically for the rack and pinion jacking mechanism of self-elevating mobile drilling rigs. This is one of the most arduous environments to which a lubricant can be exposed – not only is it subject to high loads and water washing in the splash zone, it also has to provide protection against corrosion to both the rack and pinion between rig moves. In addition, this is one area of operation where a lubricant is deliberately introduced to the marine environment in the course of normal use. The oceans and seas constitute the major part of our planet, using an environmentally responsible open gear lubricant can minimise environmental impact and help conserve marine biological diversity.
Castrol BioTac OG has been specifically formulated to minimise impact upon the marine environment. All the components of Castrol BioTac OG have been selected for their reduced* 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. As a result Castrol BioTac OG is OSPAR compliant and contains no substitutable components. It is key that the lubricant performance of BioTac OG is not inferior to those greases currently used on leg racks – any performance deficiencies would prevent its adoption or result in higher consumption, negating its environmental benefits. We have used the performance characteristics of the best available traditional lubricants as
the specification for Castrol BioTac OG and have matched these by using new additive technologies. The thickener structure is highly resistant to water washing and provides outstanding corrosion protection, ensuring that the volume of lubricant introduced into the environment is similar to when traditional products are used.
