Featured client case studies

CLIENT CASE STUDY: AET

Reducing feed rate by 32%

The marine vessel Eagle Varna was experiencing a high feed rate of the cylinder lube oil. Hans Jensen installed HJ SIP valves on MAN Alpha, which resulted in a significant reduction in cylinder lube oil consumption.

Engine: 7S80MC-C

CLIENT CASE STUDY: HAFNIA

Tripling liner life time

Hafnia, a member of BW Group, upgraded the engine’s cylinder lubrication system onboard their Medium Range Product Tanker, BW Egret, in January 2020. Liners previously had a wear rate that exceeded the maximum allowable limit.

Engine: 6S50ME-B

CLIENT CASE STUDY: COSTAMARE INC.

Face-off between HJL and standard lubrication system

A joint test with MAN Diesel & Turbo (MDT) and Hans Jensen Lubricators determined the effectiveness of HJ Lubtronic SIP over standard lubrication on a new, super-long stroke, electronically controlled engine which was prone to high rates of cylinder wear, cold corrosion and high feed rate.
