How did the shipping sector welcome sulphur 2020?

The first of the VLSFO fuels we use on our ships since January 1, 2020 impressions showed that not all parties were well prepared for this preparation process. Especially the subject When we consider it from the technical point of view, the most basic of a ship for commercial activity The requirement is that ship machinery can be operated efficiently without malfunction. we all know

What have we experienced after January 1;

Some companies did not encounter any problems. He sees it as a chance and We want to point out that there is no guarantee that they will not encounter. The underlying We can show the instability of fuels as a reason. Fuel purchased from many countries It is not compatible with each other and even alone causes machine damage. can be.

- A group of companies experienced Cat-Fines because they received fuel with high Al + Si ratio, and some companies

Although it was not a very high value, it was faced with cat-fines. Well more Even in HFO fuels used before 1 furnace, Al + Si ratio is higher, the ship was not facing the Cat Fines problem. At this point, a I want to make a point. All coaches are usually more than this amount or They dealt with the island scarcity, but they forgot the molecular structure. Molecular structure even if the amount is small the small Al + Si passed through your filters easily. Therefore a 10 micron filter Those who do not consider their suggestions should once again consider the issue. - Separator efficiency has become a debatable issue. Of fuels and Good for fuels with low temperatures due to their low flash point we could not provide separation. Some brands went to revisions in separators, many brands but did not change.

- Continuous low tbn due to the use of low-sulfur fuel in cylinder lubrication Companies using cylinder oil must be prepared for piston and liner damage.

It Although your machine manufacturers will give the most accurate answer at this point, a general information It is more correct to use BN 70 and BN40 oils every 1 week.

Manufacturers have stated that it will be, but especially in BN100 users, liner shine and There were problems with oil not sticking to the cylinder wall. Most oil companies are also We are experiencing difficulties due to the fact that we cannot meet at this point and produce a single type of oil.

Conscious to comply with company instructions to manage oil use in operational terms You must have ship managers. Where old information changes, constantly new In a period of knowledge, traditional thinking systems benefit nobody. it is clear that it will not. -For all fuel types, pour point, sediment, catfin sa, paraffin or aromatic mixture Suitable working conditions should be provided by paying attention to and viscosity. - Companies that suffer from layer damage cannot provide spare liners and pistons or can be provided for long periods. Not prepared for this process in terms of spare parts we got caught - Ships passing to MGO at ports will not be able to go from ship to ship before 1-2 hours. With the change, the complete VLSFO from the system by switching to thin fuel at least 3-4 hours before they must make sure that the fuel is purge. This is because with some fuels, MGO Even in the amount of VLSF fuel mixing and waiting fixed, especially in the fuel create adhesive properties and barrelplunger, such as fuel indexes It causes the staff to hold back. This grip is not a simple grip, it When you touch each other, you cannot separate your hands or keep the plunger from the barrel.

strong enough that you will have to tie it in a vise and disengage it.

In these days when there are many problems related to new fuels, the ship stores a reserve fuel and preferably MGO on-board I would like to emphasize the necessity. Also a very meaningful price between VLSFO and MGO When the risks taken by making the account book due to the lack of difference We can drive our machines with MGO until the fuels are characterized for a while longer. It should not be forgotten that this process should be handled by all parties in all aspects. It is a necessary issue and we can take more effective measures by sharing their experiences.
