CYLINDER LUBRICATION AS AN EFFECTIVE MEANS TO SOLVE CHALLENGES IN SHIPPING 2013

MR. CHRISTIAN HANS JENSEN


Challenges in Shipping 2013

Slow Steaming

New Environmental Regulations

Need for more simple

Operation

Cold Corrosion

New Engine Types(G-Type)

Increasing Oil Prices


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


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

Solution:


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

Challenges:


Solution - Cold Corrosion

85% MCR

Injection of fresh lube oil with every piston stroke

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

Solution:


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:


Solution - New Regulations

• Reduced cylinder oil consumption with Hans Jensen Lubricators leads to higher engine energy efficiency, thus contributing to ship owners SEEMP.

Solution:


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 – Simple Operation

• Automatic adjustment of consumption – regardless of feed rate

• Electronic flexibility

• Training in correct use is part of the package

Solution:


Challenge – Increasing Costs

• Increasing cylinder oil prices.

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!

Solution:


Conclusion

Welcome the challenges of todays shipping market:

Slow steaming Cold Corrosion Introduction of new engine types (Ultra Long Stroke) New regulations (SEEMP) Simple Operation Increasing costs
