Well, by putting weight/cargo in a floating hull you increase its displacement.

Displacement is a function of deadweight. The higher the deadweight, the higher is the displacemnt. However it does not offer a good insight in the size of the ship in terms of dimensions. A standard VLCC carries 320000 DWT these days so loaded displacement would be about  360000 tonnes. Typical dimensions are 330 meters overall, 60 metres wide and 30.50 depth.
A Triple E Maersk ship has a DWI of about 195000, same beam,same depth but roughtly 70 meters longer. Lightship would be probably around 40-45000, but I have no data on that.

So really displacement is not going to give you a proper size indication. And for more extrme figures, just look at cruise ships, which have hardly any deadweight to speak of.

OK, David, but they fulfill the same role as the yacht tenders, so these could be put there as well. But as Clyde mentioned, taking people from shore to an offshore contraption, whether floating or fixed is their main design purpose, so that is where they should be.  Like my hobbyhorse, an LR2 carrying crude oil is not a crude oil tanker but a product tanker.

I think I remember having seen some large cruise ships that carry their own passenger tenders on board, when visiting ports for which they are to big to enter, such as Monte Carlo. What category are these in?

De Hoop

The J. Smit yard in Alblasserdam was the first yard in the Veolme empire,which later culiminated in the RSV Gropu ans was subsequently dismantled. Newbuilding has ceased there ages ago and I doubt that anybody who was involved in that yard is still alive. There could be archives somewhere, but it would be difficult.

De Merwede Schipyard is still part of the IHC group, but their activities have been reduced significantly since 2015.  This is IHC's website
6  Shipspotters all over the world / Trip reports / Shipspotting at Rozenburg on: May 04, 2017, 12:42:57 pm
Since 01/05/2017 the Restaurant "De Veerheuvel" at the ferry terminal in Rozenburg has got new management. The previous manager lived in the small cottage at the back of the restaurant and the good news is that the new manager is planning to offer this as a B&B facility. I can hardly imagine a better starting place for shipspotting operations if you are not an inhabitant of our little village.

The Database is not something that the Admins can maintain. Up till early 2015 the data were supplied by the site Gross Tonnage, and the site software just incorporated their data. As GT data also included ships on order (by the IMO number), ships that were completed after the demise of GT (such as the ship you are referring to) still show some input on the data sheet on Ship Spotting, but soon, with orders placed for ships after the end of GT, the data sheet will be totally empty.

Efforts to link to another external data source have so far not been successful.

Paul (?). If you are having trouble identfying an older tanker, just sent me a message and I'll do it for you. And for that matter the older tankers are causing far less problems than the newer ones where the mix of product and crude tankers is much more diffuse.
When other people come up with extra info, it will still be the adimin who will have to physically add the info to the photo.

Perhaps a Port Authority could issue a permit for such ship to leave the port only when under tow. On the other hand, that would probably prevent the shipowner from doing anything and the burden of the removal of the ship will fall on the Port Authority.

Edit: I may have erroneously assumed that the ship was heading for a Turkish scrapyard.

Hi Dave, yes things are never as  straightforward as one would hope, however the Class says :

Main purpose:
Crude oil carriage
Additional purpose(s):
Oil products carriage at high temperature
Oil product carriage, low flashpoint (< 60 C)
Oil product carriage, high flashpoint (>= 60 C)"

Based on the additional purpose, one has to conclude that she can also carry light oil products, which I suppose means that she is coated, and therefore qualifies as a product tanker. From the pictures I have of her (As AGATE V) she looks like an bunkering tankers and just like so many modern bunker tankers these days, they carry HFO, which is even heavier than crude oil, but they are still considered product tankers. In Lloyds Register this particular ship is said to be a products tanker too.

As I said in the opening post here, many product tankers do carry crude oil form time to time, but non-coated crude oil tankers will never carry (light) products. (And also there are sometimes exceptions, because recently several newbuild crude tankers coming from Korean yards have been known to make their maiden trip carrying a full cargo of light diesel fuel to Western European ports)  

But David, this will always be discussions about what is what, and as long as we do not simply have an age-bracker system for tankers, just like for bulkcarriers, we have to follow what we have, and as it says on the main page, Shipspotting is the source of the best information, so let's all try to make that happen....

Interesting to know that people were already worried that she would not pass her second survey, as they found haircracks in the hull...

The purpose of my plea was to make people post in such a away that photographs (there are well over 2.2 million of them now)are easier to find and can therefore be more satisfactorily enjoyed.

While I appreciate what you say Pieter, if posters have to do too much research before they can post their photographs, many will not bother. Personally I feel that there are too many categories, and that they could be simplified without detriment to the site. However it may be too later to change anything now.

Most of the research has already been done and is reflected in the summary pages. Actually I cannot fully understand why people would not bother to post if they should do something by themselves. With due respect I would argue that most people like to know what they saw and tell us about it in a correct way, rather than just snapshooting about and empty the SD-cards on this site.

Dear Poster

During the last couple of years we have put considerable effort into reorganising the tanker sector. It had been somewhat neglected, but we feel now that it is back on track again. The most delicate task was to differentiate between crude oil tankers on the one hand and chemical and product tankers on the other, which, especially for the larger ships, is not immediately obvious from the outside.

Equasis is notorious in classifying many products tankers (i.e. there cargo compartments are coated to be able to carry lighter products such as gasoline and naphtha) as crude oil tankers, taking over the definition from Lloyds/Fairplay which calls them crude oil/products tankers. Equasis subsequently cuts of the second part of the definition and uses the crude oil part only.

This results that in many times photos are allocated to the crude oil category, which in reality should be under product tankers. It is a time consuming effort to check each shot all the time.

There is one way for everybody to help us preventing this. Underneath each picture there is a link to the summary page of the ship. After opening that page you can see to which category earlier posted pictures have been allocated. If you follow the "majority category" you will most likely choose the correct one. In case you seriously question "our" choice, do not hesitate to contact us, we do not claim to have perfect knowledge.

For new ships the summary page may not yet work satisfactorily, but you can always try to find new ships on the website of the owners or even the builders. This may sometimes give a proper indication whether the ship is a (clean)product tanker or not. Type indications for product tankers are generally MR/LR1/LR2 and now even LR3 ships (Suezmax Size)are becoming increasingly popular. If the owner calls a ship Aframax, or "dirty" one may assume that she is not coated, or that her coatings are no longer properly applied.

And yes, even clean product tankers can be used to carry crude oil, but no crude oil carrier can be used to carry lighter products, hence the differentiation. Many clean product tankers do also carry vegetable oils, but that should not result in them being classified as vegetable oil tankers.  

Many thanks in advance to everybody and keep the tankers coming.
