Reducing CO₂ emissions: Why lubrication technology matters in the decarbonisation of shipping

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.

The interplay between combustion, lubrication, and emissions

Optimised cylinder lubrication is fundamental to reliable, efficient engine operation. Precisely timed dosing reduces friction and deposit‑related losses, protects rings and liners, and helps avoid oil‑derived particulate formation. Conversely, excessive cylinder‑oil feed elevates particulate emissions and undermines overall efficiency.

Why smarter lubrication equals smarter emission reduction

• Precision dosing cuts cylinder oil use substantially. Electronically controlled systems have demonstrated savings of up to ~50% in service and test programmes.
• Lower oil and fuel burn means lower CO₂. Reducing wasted lubrication and associated losses supports improved fuel efficiency — reducing both operating cost and emissions.
• Effective lubrication supports performance under EEXI and CII. By sustaining efficient engine operation and carbon‑intensity outcomes, advanced lubrication assists day‑to‑day compliance efforts within these regimes.
  

The strategic adoption of advanced lubrication technology aligns with the broader goals of sustainable shipping. For shipowners focused on reducing CO₂ and total cost of ownership, investing in precision lubrication systems — such as HJ Lubricators — delivers measurable, near‑term gains that complement the regulatory pathway.

Conclusion: Charting a course for decarbonised shipping

In the drive towards the IMO’s 2050 ambition, embracing smarter cylinder lubrication is a practical move that delivers immediate emission reductions and operational savings on board today’s fleet.
