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.… Read more

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.
