Castrol’s approach – Bio Range

Castrol Bio Range products have been created for a range of applications throughout vessels where leakages are a risk or there is an oil-to-sea interface

From reducing costs to environmental legislation, we understand the pressure the marine industry faces. That’s why we engineer lubricating products to perform at high levels even under demanding conditions. Our constant innovation helps reduce the environmental impact of spills and leaks from stern tubes, thrusters, bearings, hydraulic systems and deck machinery.  

Castrol BioBar, BioStat and BioTac are rigorously tested using industry standards for bioaccumulation, toxicity and biodegradability. The entire BioStat, BioBar and BioTac product ranges are registered under OSPAR and meet the US 2013 VGP criteria for Environmentally Acceptable Lubricants (EALs). This means you can be extra confident that the world-class products from Castrol truly suit your needs. 

Equipment

Environmental Risk

STERN TUBE

Oil can leak from stern tubes and thrusters, particularly if shaft seals are damaged or worn. Silt and mechanical damage from fishing nets or ropes can accelerate normal wear. Thrusters can be more affected because of harbour debris.

BOW AND STERN THRUSTERS

Oil can leak from stern tubes and thrusters, particularly if shaft seals are damaged or worn. Silt and mechanical damage from fishing nets or ropes can accelerate normal wear. Thrusters can be more affected because of harbour debris.

Header tanks ensure positive pressure on lubricants, so leakage is normally outwards instead of water coming inwards.

DECK MACHINERY

Greased bearings and open gearing of cranes winches and windlass are subject to water wash.
Hydraulic systems (deck hatches and cranes) can be subject to leaks through hose failures.
