Case study: Securing Performance After Smartlube 4.0 Retrofit
OEM precision. Proactive service. Zero compromise on uptime.
When a two-stroke engine onboard an in-service vessel was retrofitted with the fully electronic HJ Smartlube 4.0 cylinder lubrication system, the objective was clear:
- Reduce cylinder oil consumption
- Improve cylinder condition
- Ensure stable operation under varying engine loads
- Avoid off-hire and unnecessary downtime
The installation was completed during scheduled port calls – without immobilising the vessel.
This case highlights how structured commissioning and final system inspection ensure reliable performance after a retrofit installation.
From Production in Denmark to Commissioning in China
All Smartlube 4.0 equipment was assembled and thoroughly tested at our production facilities in Denmark before delivery.
To ensure smooth installation onboard:
- All cables, piping, bolts, and installation materials were supplied by HJ Lubricators
- The system was pre-configured and function-tested before shipment
- Installation planning was aligned with the vessel’s sailing schedule
The retrofit was carried out by HJ service technicians together with the vessel’s crew, allowing installation to be completed across port stays and during operation – eliminating unnecessary downtime.
Location: Huanghua Port, China
The Challenge
Retrofitting an advanced electronic lubrication system on a vessel already in operation presents several risks:
- Incorrect calibration is affecting the feed rate accuracy
- Incomplete integration with existing engine control systems
- Uncertainty among the crew regarding system handling
- Potential performance deviations during early operation
Without proper commissioning and inspection, even the most advanced two-stroke engine lubrication system may not deliver its full efficiency potential.
The Solution: Commissioning and Final System Inspection
This service visit focused on inspecting and approving the completed Smartlube 4.0 installation, ensuring that the system was fully operational and correctly configured.
The scope included:
Comprehensive system inspection
Verification of all installed components, injectors, control units, and sensors forming part of the new cylinder lubrication system.
Final adjustments and optimisation
Fine-tuning of parameters to match engine load profile and operational pattern.
Functional testing
Complete commissioning procedure to test all electronic and mechanical functions, ensuring correct oil dosage per engine revolution.
Crew training
Onboard instruction to ensure the crew felt confident operating the system, adjusting feed rates, and understanding performance data.
The Result
Following commissioning and inspection:
- The system was fully operational and verified
- All functions tested and documented
- Crew trained and confident in daily operation
- Installation completed without vessel immobilisation
The vessel can now operate with a fully optimised electronic cylinder lubrication system, supporting both fuel efficiency and emissions reduction.
Why Commissioning Matters
A proper commissioning process ensures that a newly installed lubrication system performs exactly as intended.
It is about:
- Verifying correct oil atomisation and distribution
- Securing optimal feed rate settings
- Preventing under-lubrication and cylinder scuffing
- Reducing excessive oil consumption
- Protecting cylinder liners and piston rings
With Smartlube 4.0’s fully electronic control, precise calibration is critical to achieving:
- Improved marine engine efficiency
- Reduced cylinder oil consumption
- Stabilised cylinder condition
- Lower risk of unplanned downtime
