Cement Tankvaart

[Cement Tankvaart houseflag] image by Jarig Bakker, 31 Oct 2006

Today we deal in cement, that is to say, it is Cement Tankvaart’s turn to be introduced - the name means "Cement Tank Shipping". Largely belonging to the Dutch Enci BV cement group, itself part of the large German Heidelberg Cement concern, RTC or ‘Rederij Cement Tankvaart’ operates a fleet of nearly two dozen self-unloading bulk ships equipped with tanks, made up of vessels between 250 to 1350 metric tonnes.

These facts were gleaned from the Enci website, showing the fleet’s house flag at the bottom of this page: This flag is shown, as a drawing, on the Binnenvaart site but it is not very well done as confirmed by Jarig who saw it in the cloth. His description: green field, (stylized) white letters ‘c’ and ‘t’ enclosing a small black  letter ‘r’, together forming a logo taking up a large part of the flag.

Some Binnenvaart pages showing the flag (also on photo): vessels ‘Vijzelgracht’, ‘Raamgracht’, and ‘Rozengracht’ respectively: (click camera logo at bottom of page to get to another and better photo).

[Chemgas houseflag] image by Jarig Bakker, 19 May 2006

Jansen & Van Heck in their book “Duwvaart” (pp. 25-28) are very specific on the founding date of ‘Gastankvaart Maatschappij Chemgas BV’ at Rotterdam: 13 August 1965. They add that this firm (“Gas Tanker Shipping Co. Chemgas”) was originally the tanker division of the famous ‘NV Handels & Transport Maatschappij Vulcaan’ at Rotterdam… to be commented upon in future, I hope.
Briefly put, Chemgas transports gas, liquid gas, and ammonia.

As usual, this source shows the house flag in b/w: on a blue field is a white lozenge containing the black outline of a hexagon with black dots on the corners and three blue waves running through this hexagon.  See this chemical-looking flag flying, here. Image above after Josef Nuesse’s site, where however we find a second flag.  This one, on a white field with one blue triangle in the upper hoist and a similar one in the lower fly (each bearing three white waves), shows the emblem encountered before in a slightly modified form.  The black dots have become little black circles and the three blue waves seem to be flowing away towards the fly!  Lastly, under the hexagon we read ‘Chemgas’ in black lower case letters.

So there is a bit of a problem, “Duwvaart” gives the blue flag under the name ‘Chemgas’ whereas Nuesse shows two flags, one of which is largely white and bears the name ‘Chemgas’ but stating both of them as belonging to ‘Chemtrans’.

We encounter the second emblem or logo on the company website.
“Chemgas (a name used throughout, jm) provides logistic services for waterway transport and bulk storage of chemical gases and LPG. These services are based on our highly efficient and flexible fleet of purpose-built inland- and seagoing barges operating in Europe.”

There seem to be separate transportation divisions: ‘Chemgas Shipping BV’ and ‘Compagnie Fluviale de Transport de Gaz S.A.’ or “River Gas Transport Co.” at Lyon, France (it has a logo in the national colours but I have not yet found a flag).  Also found on the net was the name ‘Chemgas Intercoastal’.

Could it be that the name Chemtrans was never really used by this firm?

[Cotrano houseflag] image by Eugene Ipavec, 21 Dec 2007

The website of the Dutch company Cotrano BV is under construction (hence, slated for future visit): The company seat is Krimpen aan de IJssel, a little town where the River IJssel joins the Nieuwe Maas to almost immediately reach Rotterdam if you travel downriver.

A sand and gravel extractor and seller, Cotrano – a member of both CBRB and VBKO (Dutch association of waterway construction and dredging companies) – operates its own fleet of vessels. See following Vlootschouw page showing ‘Cotrans 8’: The flag is flying and for good measure it is also painted on the steering hut of this barge.  Furthermore said house flag appears – as a drawing – on the Binnenvaart site which describes the careers of a number of ships mostly named ‘Cotrans [number]’: orange field, a white trapezium between two white horizontal stripes (not touching the flag’s horizontal edges); on the trapezium an orange stylized initial ‘C’ alongside an orange triangle, both placed above an orange wave.

The drawing is too sketchy to rightly determine the width of the various stripes (OWOWO) but it might be 1:1:4:1:1.

[CTA houseflag] image by Jarig Bakker, 3 Mar 2005

Jan Mertens reported this link with mainly Dutch houseflags. CTA - white flag, blue open ship, containing red "ct8".
I think this is "Container Terminal Acht (8)"...

[CVV houseflag] image by Eugene Ipavec, 20 Aug 2008

No shippers’ union or logistics group this time but C.V.V. or 'Coöperatieve Vereniging van Vletterlieden' (i.e. Cooperative Association of Flatmen/Boatmen), established at IJmuiden which is at the mouth of the North Sea Canal linking Amsterdam to the sea. Website (in Dutch)  showing the house flag (as a flagoid and a real life picture of the flagoid):

What do ‘vletterlieden’ of flatmen do?  They help moor all kinds of vessels, tow, transport goods and personnel to and from said vessels, fight oil spillage, help pilots and other specialized personnel, etc.  Field of activity is IJmuiden port complex including the locks.  Organized into work groups of ten, the entire organization employs about fifty people, most of them being cooperative owners; it has been active “for almost sixty years now”.

Equipment consists of so-called winch cars and tractors, a few cars and four motor boats.   See ‘Werkmateriaal’ (left menu) to get an idea and admire the flatmen’s skill in throwing cables: short fims reached via red titles at end of first subpage ‘Het “Haakie”’ (i.e. the hook).
The photos on the site do not show the flag.

Blue flag with white diamond touching the edges, black initials ‘C.V.V.’ in the diamond (which has been drawn with a black holding line possibly absent in real life).
