Nederlandse Pacific Tankvaart (Caltex). I think you will find that there is no black edging to the white disc i.e. it is the normal Caltex Petroleum Corporation flag. One of the misleading tricks is for some sources to separate some colours by use of black lines and as they are not consistent with this format one is left unsure whether the lines are part of the design or not. The same comment applies to Shell Tankers.

by Jarig Bakker, 20 Oct 2003

N.V. Petroleum Industrie Maatschappij, Den Haag.
Houseflag: white with on the hoist in a vertical row red capitals PIM; in the fly a blue fimbriated oval with the firm's logo. (I searched on the Internet but couldn't find a logo like that; however the houseflagchart of "De Blauwe Wimpel", and "All about Ships & Shipping, 1959" have the same lettering of the logo.

Petroleum Industrie Maatschappij. Sources tend to offer conflicting detail with dates and exact names but it seems that the company originated around the 1890s as American Petroleum Co., which despite its name comprised a Dutch and a Belgian branch with a white flag bearing a saltire of the respective national colours i.e. a triband of the Dutch from upper hoist to lower fly and one of Belgium from lower hoist to upper fly, this being surmounted by a white diamond which most sources show as defined black but Talbot-Booth shows undefined, this diamond bearing the black letters "APC". Reed 1912 shows the letters as being "A.P.Co." with the 'o" enhanced and the dot under it but this seems incorrect. After WW1 the company split into two, probably following the takeover by Standard Oil Co. of New Jersey. The Belgian branch continued as American Petroleum Co. Société Anonyme Belge until May 1939 when it became Standard American Petroleum Co. S.A. and going by Talbot-Booth 1936 & 1937 it continued to use this original flag. In 1940 its 2 ships were transferred to the associate Panama Tanker Co.. Post WW2 they resumed becoming Esso Standard (Belgium) S.A. and continued with the basic flag but replaced the lettering with the blue "Esso". Around 1970 it became Esso Belgium S.A. but ceased as shipowners in the middle 1990s and I do not know whether it continued with its own flag up until then or whether it adopted that of the Esso Group.
The Dutch branch continued initially as American Petroleum Co. and adopted a new flag of white with a green bend bearing a diamond charged with the black letters "APC" and later became Standard Amerikaansche Petroleum N.V. when it adopted its first variation of the Esso flag placing the red letters "SAPC" in vertical line in the hoist before changing by or during WW2 to N.V. Petroleum Industrie Maatschappij.
At the end of the 1950s it became Esso Tankvaart Maatschappij with another change of flag and continued in shipping until the latter 1980s.

Nederlandsche Koloniale Petroleum Maatschappij

For the Stanvac house flags on FOTW-ws see the pages “Petrol company Houseflags (The Netherlands)” and “House Flags of U.S. Shipping Companies: ExxonMobil”.
For a number of years, a Dutch variant of this flag was flown by the ‘Nederlandsche Koloniale Tankvaart Maatschappij NV’ (i.e. Dutch Colonial Tank Transportation Co., Ltd) established at The Hague.

The following highlights were found on this interesting site relating the history of Standard Oil, Esso, etc. from a Dutch viewpoint: In 1926 the ‘Nederlandsche Koloniale Petroleum Maatschappij’ (i.e. Dutch Colonial Petroleum Co. founded in 1912 by Standard Oil and Socony Vacuum Corp.) started shipping oil between the Dutch East Indies and Singapore. 1935, name change to ‘Nederlandsche Koloniale Tankvaart Maatschappij’. Most ships lost during the war with Japan, 1942-1945. New name change in 1947: ‘Standard Vacuum Tankvaart Maatschappij'. Van Uden signed over tanker fleet in 1958; the next year Dutch ships were no longer welcome in Indonesia so the tankers were leased to Petroleum Shipping Services Co. Inc. (Panama). New name in 1959: ‘Standard Vacuum Petroleum Transport’ shortened to ‘Stanvac’ in 1960 which company no longer operated ships of its own.

The Dutch maritime discussion forum ‘Kombuispraat’ (i.e. “galley talk”) shows very interesting house flag material: The first flag plate is said to be pre-WWII, which I readily believe, with no. 12 showing the NKTM flag. The Stanvac relation is obvious given the white field, the blue company name – reduced to the key word ‘KOLONIALE’ – and the bulging red lines enclosing it. In this version, however, the red lines are lengthened and actually touch the flag’s edges.
