Slashing MPC Values by 85%

The challenge 

An offshore drilling platform in the offshore oil & gas industry experienced recurring reliability issues within its compressor lubrication system. Independent oil analysis revealed severe varnish contamination (MPC value 43.0), alongside poor ISO cleanliness, leading to bearing failures, filter blockages, and overheating during operation.  

Customer savings & impact 

Following continuous Delta-Xero oil filtration, the operator achieved measurable improvements critical for offshore operations: 

• Varnish potential reduced dramatically, with MPC values falling from 43.0 to 6.1 

• ISO cleanliness improved from 22/20/17 to 16/14/10, restoring oil to satisfactory operating condition 

• Unplanned downtime eliminated, with bearing failures, blockages, and overheating resolved 

The full case study shows how contamination was reduced over time, why traditional filtration failed, and what this meant for uptime and maintenance cost offshore.
