Challenge - Slow SteamingChallenges:
• 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
Hans Jensen Lubricators A/S – www.hjlubri.dk – [email protected]
Solution - Slow Steaming
• 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

Challenge - Cold Corrosion
e.g 85% MCR
Injection of fresh lube oil e.g every 4 piston strokes (intermittent)
OCCURS WITH COMPETING PRODUCTS
Liner wall – high temperature
Liner wall – Low temperatureSulphuric acid condensating
e.g 25% MCR (slow steaming)
Injection of fresh lube oil e.g every 12 piston strokes (intermittent)
OCCURS WITH COMPETING PRODUCTS

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

Challenge – New Engine Designs
• 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.
Challenges:

Solution – New Engine Designs
• 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

Challenge - New Regulations
• 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…”
Challenges:

Challenge – Simple Operation
• 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
Challenges:

Solution – Increasing Costs
• 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!
