3. Challenge - Slow Steaming
Challenges:
•
Slow steaming has become order of the day
•
Yet most engines are not built for slowsteaming
•
Danger of over lubrication
•
At lower RPMs, cold corrosion is likely to happen,
unless the engine is equipped with cylinder
lubricators that are designed to meet slowsteaming
requirements

4. Solution - Slow Steaming
Solution:
•
Hans Jensen Lubricators has products to secure
optimum balance between oil consumption and
cylinder liner wear:
• Lubtronic
• Mechtronic
•
Fresh cylinder oil with every piston stroke –
regardless of engine load (Fresh alcalinity)
•
Hans Jensen Lubricators have load regulations,
where consumption will adjust automatically when
load is changed

5. Challenge - Cold Corrosion
Challenges:
e.g 85% MCR
e.g 25% MCR (slow steaming)
Injection of fresh lube oil e.g every 4
piston strokes (intermittent)
Injection of fresh lube oil e.g every 12 piston
strokes (intermittent)

BN is needed to neutralize acids. You do not
need more oil, but better use and distribution.
Injection frequency should be 1:1

7. Challenge – New Engine Designs
Challenges:
•
More and more engines with Super- and Ultra Long
Stroke.
•
Cylinder liners on G-engines are more challenging to
lubricate adequately.
•
Prone to extensive wear due to the long distance
from injection point to TDC
•
Hans Jensen Lubricators has adapted to meet these
new challenges.

8. Solution – New Engine Designs
Solution:
•
Utilize scavenge air swirl to reach top of liner with Hans
Jensen SIP (swirl injection principle) lubrication system.
•
Injection of cylinder oil by high pressure.
•
Create uniform and stable oil film
•
One cylinder lubrication solution to fit all engine types –
Sulzer, MAN B&W and Mitsubishi

9. Challenge - New Regulations
Challenges:
•
All shipowners required to have a Ship Energy
Efficiency Management Plan (SEEMP).
•
Article 4.27 of the official IMO guideline for SEEMP
(ANNEX 19) states:
”Additional means to improve engine efficiency might
include […] Adjustment of cylinder lubrication oil
consumption…”

10. Solution - New Regulations
Solution:
•
Reduced cylinder oil consumption with Hans Jensen
Lubricators leads to higher engine energy
efficiency, thus contributing to ship owners SEEMP.

11. Challenge – Simple Operation
Challenges:
• With many tasks onboard a vessel, there is a
need for simple and flexible solutions
• Crew changes frequently, and cylinder
lubrication solutions should be easily
manageable and adjustable
Hans Jensen Lubricators A/S – www.hjlubri.dk – hjl@hjlubri.dk

12. Solution – Simple Operation
Solution:
• Automatic adjustment of consumption –
regardless of feed rate
• Electronic flexibility
• Training in correct use is part of the package
Hans Jensen Lubricators A/S – www.hjlubri.dk – hjl@hjlubri.dk

13. Challenge – Increasing Costs
Challenges:
• Increasing cylinder oil prices.
Hans Jensen Lubricators A/S – www.hjlubri.dk – hjl@hjlubri.dk

14. Solution – Increasing Costs
Solution:
• Implement technology with a potential for
reducing cylinder oil consumption
• Make sure that cylinder condition is good also
when slow steaming
• Savings from app. 30.000-300.000$ pr. year
• Slow steam and benefit from it!
