This is the highest credit rating in the D&B rating model and is awarded to 4898 companies, i.e. 4.4% of the registered companies in Denmark Top of page MAN B&W Marine Engine Programme We have noted that our name is listed in the MAN B&W Marine Engine Programme (4th Edition April 2003). We appreciate this confirmation of our status as approved supplier. At the same time, however, we are concerned about the misconception possible due to the way the text is written. The higher consumption of cylinder oil specified for "Hans Jensen Mechanical lubricator" is based on the MAN B&W chosen use of our lubricators, and the chosen non-return valve design for the injection of the cylinder oil. It is not based on an optimal use of our products. For explanation of the technical background for the above, please see www.hjlubri.dk/flensburg3.pdf Top of page UPDATES - april 2003 SIP - What is new compared to other solutions? We are currently often presented with the question: "Please compare SIP lubrication to other solutions so we can understand the difference." In this connection, we are happy to make a general presentation of how we view SIP in relation to alternatives in cylinder lubrication. - SIP is a new principle for distributing the cylinder oil on the entire circumference of the liner wall. In the design, we have taken into account that piston rings moving vertically are not designed for a proper circumferential distribution of a minimal cylinder oil quantity.
- Based on the engine designer argument: "cylinder liner wear is primarily corrosive wear" SIP is a principle designed to allow fresh supply of cylinder oil to the upper liner wall at every engine revolution. This is done, in order to give best operating conditions for the additives in the cylinder oil.
- SIP lubrication is acknowledging that correctly utilized, mechanical lubricators can provide adequate and proper timing for injection of cylinder oil.
We are not aware of any other cylinder lubrication oil feeding system providing similar functions. Introducing the SIP system and requesting the sceptics to express their hesitation in technical arguments, we are faced with none. Therefore, if your request for SIP lubrication is faced with hesitation, please let us have the technical arguments. We shall be happy to reply to relevant scepticism. At worst, we can learn and improve! - Experience from installations confirm that we are on the right track. - Currently our reference list includes approx. 70 SIP installation projects.

UPDATES - december 2002
Owners wanting more SIP applications We are happy to see that owners carefully applying SIP as a test, are convinced! Noting that our reference list is rather short when it comes to the number of owners applying the system, this is actually a strength when we look at the number of vessels. In average the owners have each 8 vessels applying the SIP solution. Initially penetrating the market this way is much more interesting than seeing many owners with a few installations.
Prevention of corrosive Liner Wear Liner wear is by the two largest designers of 2-stroke diesel engines attributed to corrosion created by acid developing from the sulphur content in the fuel oil. SIP lubrication is the only standard cylinder lubrication system forcibly providing fresh acid neutralizing cylinder oil to the entire circumference of the cylinder liner for every revolution - hereby a very good reason to apply SIP lubrication!
Engine Designers' "No Objection" When an engine designer applies the term "No objection" to the application of SIP we trust it means: NO OBJECTION. Following the applications in service and receiving updates confirming good performance data, we look forward to the day when you as customer see the effect of this; technical arguments invalidating the no objection is - based on gained experience - not foreseen. For applications on NEWBUILDINGS and RETROFITS alike we have the necessary close cooperation with the engine designers and/or engine maker in order to ensure that we apply the correct design data and do not risk conflict with the design of the engine.

HANS JENSEN LUBRICATORS GOES WORLDWIDE WITH GOLTENS Oslo, Norway, 25 November, 2002 - Danish cylinder lubrication specialist, Hans Jensen Lubricators A/S has awarded Goltens an "Authorized Service Provider" agreement for its line of cylinder lubricating equipment, featuring the leading lubrication technology, Swirl Injection Principal (SIP). The agreement confirms Goltens' strong market standing in the global ship repair and service industry and meets Jensen Lubricators' demand for a trusted, worldwide service partner. Jensen Lubricators manufactures lubrication systems for 2-stroke engines and is a recognized supplier to leading diesel engine manufacturers. "Jensen Lubricators manufactures state-of-the-art lubricators and a growing number of shipowners and operators are appreciating the advantages of this company's SIP technology, i.e. considerable cylinder oil saving and low wear rates," says Preben Liltved, vice president, Goltens Europe. Says Liltved: "Installing and servicing Jensen lubricators perfectly matches Goltens' business activity in the retrofit and diesel engine repair and maintenance service markets." "Goltens' staff of trained technicians, engineers and mechanics are accustomed to the major makes of main and auxiliary diesel engines and are the optimal service partner", says Thomas Jensen, vice president sales, Jensen Lubricators. He confirms that Goltens' staff would undergo special training to undertake retrofit, service, and mounting jobs, when and where required. Says Jensen: "Up to now, Jensen Lubricators has used its own skilled engineers for installation. But we felt that Goltens' speed of service, worldwide network and skilled mechanical staff ensured proper performance of this type of work." Says Jensen: "We are convinced that clients are best served with specialists to undertake many jobs. Ships must depart on time with the job successfully completed. This agreement is made to ensure better service to our international customers." SIP lubrication can be installed as retrofit on all major engines, i.e. MAN B&W, Sulzer and MHI designed 2-stroke engines and, according to Goltens, there is huge growth potential for SIP in the retrofit market. "SIP lubrication grants operating economy and is a must in the retrofit segment. Our focus will be to support shipowners with retrofit SIP systems on a worldwide basis," says Liltved. Says Liltved: "We are ready to undertake full retrofit responsibility and send our engineers to every corner of the world. We will also take part in sea trials when required to confirm that an installation and setting has been properly done."
About the SIP system Cylinder wear and cylinder lubrication oil consumption are essential parameters for the operating economy of large 2-stroke diesel engines. Products able to minimize cylinder wear and/or the consumption of cylinder oil are increasingly in demand. The SIP lubrication concept meets both of these demands. Tests have shown a potential of up to 50% cylinder oil savings without trade-off liner wear.

"Sovereign Maersk" continue to be EXTREMELY low (actually being difficult to measure in spite of the now many operating hours). A clear sign of stability. Application of SIP as RETROFIT is now done on engines with designer denominations from short stroke to super long stroke engines. The engine bores ranging from 500mm to 900mm. The performance is good. Application has not been without initial problems, but none have been ascribed to the basic function of the SIP solution. We have gained the experience easing the application on coming installations. For RETROFITS, we are currently establishing relations with a number of reliable partners, allowing us to provide the necessary know-how around the world where your ships are best accessible for installation and service. NEWBUILDINGS are also specified with SIP lubrication. Engine makers have different views on their standard desired solutions. Valid technical arguments against the SIP solution, however, still remain to be heard. The rapidly increasing experience data supports this situation. An attitude of "no objection" from the most sceptical engine designers indicates that they acknowledge the performance seen and we regard this as an important step towards a formal approval. No objection can best be interpreted as: No foreseeable negative effects. For applications on NEWBUILDINGS and RETROFITS alike we have the necessary close cooperation with the engine designer and/or engine maker in order to ensure that we apply the correct design data and do not risk conflict with the design of the engine.

CIMAC Circle A CIMAC Circle was held in Hamburg on September 26th. The subject was: "Interaction between engine design, cylinder lube oil dosage and cylinder condition" In connection with this Theme we have had the following correspondence with CIMAC, and suggest interested parties to draw their own conclusions: 2002.09.06: Dear Mr. Kyratos - President We have received the invitation to the CIMAC circle at SMM and signed up to participate. At the same time, however, we have been looking at the compositon of the panel with the intent to understand how the selection of the panel has been made. As we have not been able to see the line, we would appreciate if you could enlighten us in this respect. For example we see no representation at all from the side of the providers of cylinder lubrication equipment - a group we belong to, and where ideas and experience is also generated and collected. Your soon reaction shall be appreciated regards, Thomas Jensen Hans Jensen Lubricators A/S
2002.09.19 Dear Mr. Jensen, we submitted your inquiry to Mr. Carl-Erik Egeberg, who is the responsible organiser and chairman of the event. His comment is as follows: 'The panel has been composed of representatives from a user, from the two largest engine designers and the two largest suppliers/designers of cylinder lube oil. Unfortunately a mistake as slipped-in in the title of the Circle as "lube oil dosage" should be "lube oil design". We are sorry if this mistake has caused confusion.' Looking forward to meeting you in Hamburg next week. With best regards Martina Pelzer CIMAC Central Secretariat Phone: ++49 69 6603 1567 Fax: ++49 69 6603 1566 e-mail: martina.pelzer@vdma.org ------------------------------------------------------
2002.10.02 At the CIMAC Circle in Hamburg it was said that the presentation material used would be available on the CIMAC home page. We cannot locate it. Please inform how we get to that material. Thank you beforehand. Thomas Jensen Hans Jensen Lubricators A/S
2002.10.04: Dear Mr. Jensen, the material will be placed on our website hopefully by end of next week (Oct. 11). It will be put under Congress&Events, CIMAC Circle 2002. With best regards Martina Pelzer CIMAC Central Secretariat
2002.10.11: Dear Mrs. Vacra, we have noted that the presentation material is apparently not yet on the home page, but also noted that you indicated the date as being "hopefully by..". Now we must be closer to the time where it happens, please let us now have some more specific information about when the material is available. We see that you have apparently had time to put a kind of press release on the homepage but not yet the material for the members. Your soon reaction shall be appreciated regards, Thomas Jensen Hans Jensen Lubricators A/S
For interested parties who did not have time to participate, we shall be happy to explain further. Top of page
Mitsubishi Heavy Industries press release
On 2002.08.06 Mitsubishi Heavy Industries published a press release which among others informed that the first retrofit of SIP lubrication has successfully been installed in a 7UEC85LSC diesel engine. In case further information is requested in this connection, we are at your disposal Top of page
The first MAN B&W engine born with SIP lubrication
The first MAN B&W engine born with SIP lubrication, a 10K90MC-C engine designed for HHI newbuilding 1410, was successfully tested at Hyundai Heavy Industries last week (week 17'02). The shop trial of a newbuilding with SIP lubrication is a natural consequence of the retrofit experiences presented at the CIMAC conference in Hamburg one year ago. The purpose of SIP lubrication is to ensure a good cylinder lubrication at a reduced cylinder oil quantity as compared to present standard. To solve this task, SIP lubrication sprays the cylinder oil onto a large area of the cylinder surface before the piston passes during its upward movement. With an improved distribution over the entire cylinder liner circumference, a small quantity of cylinder oil induces the same function which earlier required a larger oil supply. The results presented one year ago have been maintained in the continued operation: Cylinder wear of 0.013mm/1000h at a lube oil consumption of 0.44 g/BHPh (MCR) on an MAN B&W 12K90MC engine.
Equally interesting results are expected from the retrofit installations running on Wärtsilä Sulzer engines. Top of page Cheap Newbuildings - Low Costs for Whom? A 30-50% reduction in cylinder oil consumption, and a better cylinder liner condition is
possible with HJ SIP Lubrication as presented in our paper at the CIMAC conference in Hamburg.
The intense competition in the field of ship newbuilding and engine manufacturing has turned the focus very much towards building cost reductions. Reactions from both shipowners and engine manufacturers give us the distinct impression that building cost reductions are considered of higher value than long term benefits in operation. For some "asset players" this is of course acceptable, but for shipowners with long-term operation in mind
this situation may not be so beneficial. Consequently, we now emphasize more on life long cost performance of our lubrication systems: HJ SIP Schmierung - is the best solution in the market for minimizing the operation costs in connection with cylinder lubrication.
- applies well known and proven technology
- ensures in a simple and logical way that cylinder lubrication oil is properly and evenly distributed over the circumference of the cylinder liner.
Thus, we are presenting a new solution with long-term benefits. The choice of HJ SIP Lubrication for a newbuilding will result in very limited cost differences for the engine maker in comparison to other choices of execution. Our recommendation to you is therefore: Be an active partner in the decision of the equipment for your newbuildings, whether the choice is to decide for yourself, or to follow the recommendations of the engine maker or designer. Today's choice is tomorrow's result.
