Reclassification of tankers
« on: March 14, 2023, 08:03:39 PM »
There is a new division of the tanker category.
In order to bring it in line with the other major categories, we have chosen to use age brackets in stead of subtypes. These subtypes gave continuous debate over what was what, and required permanent attention to get things correct.
As of now you will find the Crude Oil Tankers, the Chemical and Product tankers and the bunker/water tankers in one group Tankers. with the same age brackets as bulkcarriers, with one exception, the existing class Tankers built before 1970 remains unaffected.

The repatriation was done on the year of build taken from the Gross Tonnage database, and helped with the newer data that have been recently added. Yet there is a category "unclassified tankers" for which no year of build is known. The majority of this category consists of newer ships, and will be moved to the respective age category by adding the year of build in the data set. It may take a while before every ship will be in place, so we ask your for a little patience in this respect.

We think you will find this easier to deal with, but we encourage you to include more detail in the description of your photos.

EDIT: This post was written as a reply to an earlier contribution, posted by Pieter Inpyn. His post has now been removed and not by me. (PM)

Pieter, you have raised the following points:

The difference between categories is gone, yes but it was never there for tankers built before 1970, and did you have problems with that?

How do we see the correct category for the tanker sector in the new situation? Simple, it is the age bracket, like with all other categories, where age brackets are being applied.

How do I know the type in the new structure?

That is a point where we have worked hard in the past to make that visible, by systematically identifying the tankers suitable for products/chemicals/ crude oil versus crude oil only. The problem with tankers is their flexibility and also the great difference in tank layout. coatings, use of stainless steel etc. Furthermore during its span of life tankers tend to get employed in lower segments then they were designed for, for instance coatings could be deteriorate to such an extent that the ship can only carry black oil products to keep on trading. And yet it would still be in the same category in the old system. Look also at the many smaller easy chemicals/product tanker that find life extension by using them as bunker tankers. To end all the discussions about what a photo represents in terms of tanker type at the moment that the shot was taken, we have decided to go to age brackets and put some main categories together.

And therefore we do encourage people, like many do already, to make a description of the ship that would include some words about the actual usage of the ship. And yes, people who are interested can find more information elsewhere, for instance by looking at sites of the classification societies,  etc. We also have now the possibility to amend the ship type in our own database system (based on the GT Data) where we can amend the ship-type as  deemed appropriate, and even in more detail by adding IMO classes for chemical tankers, market identifier such as MR/LR1 LR2 Aframax etc, so the fear of losing sight of what the ship actually is, should not be exaggerated.

Thanks for creating and explaining this new classification, a far better solution than it was, particularly when searching the built year is much easier.
Best wishes, Manfred
