Unlocking retrofit savings potential – one vessel at a time  As pressure grows to reduce emissions and cut operational costs, many shipowners and operators are adopting smarter lubrication strategies. But while the advantages of modern cylinder lubrication systems are well known, the actual savings potential is often less clear.  That’s why we’ve created a vessel-specific Read more

The maritime industry’s path to decarbonisation is shaped by ambitious regulatory initiatives, such as the IMO’s 2050 net‑zero ambition and requirements like EEXI and CII. While shipowners evaluate fuel choices and optimised propulsion, one critical lever, a smarter approach to cylinder oil control, often receives less attention despite its strategic impact on emissions and cost.

What is a cylinder liner? A guide for shipowners, operators, and marine engineers For shipowners, operators and marine engineers, understanding the function of cylinder liner within large marine engines is crucial for maintaining efficiency, reliability, and compliance in today’s maritime industry. In this article, we explore precisely what is cylinder liner, its importance in two-stroke Read more

Efficient cylinder lubrication is vital for the reliable operation of marine engines, supporting operational efficiency, emission reduction, and the prevention of costly wear such as scuffing. HJ Lubricators recommends integrating robust cylinder lubrication systems as part of a vessel’s holistic approach to engine care, particularly where maximising uptime and meeting stringent IMO emission requirements are Read more
