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.
Engine: 9S90ME-C

Cylinder wear in two-stroke marine engines
Efficient cylinder lubrication does not eliminate the wear of liners and piston rings completely. The goal is to control the cylinder wear rate and keep it on a normal level and to prevent other harmful types of wear. Cylinder wear in two-stroke marine engines refers to the gradual deterioration of the inner surface of the…

BLOG-POST:5 facts about advanced cylinder lubrication technology
1. What is the purpose of lubrication technology for marine engines? Lubrication technology for marine vessels involves the use of advanced lubrication systems to reduce friction between cylinder liner and piston rings by forming a thin and even oil film. Furthermore, lubrication prevents wear of liner and piston rings, neutralizes sulphuric acids, keeps the piston,…
