The B4 - B5 - B 6 - B 7 en B 8 were build by Sleephelling Mij. Scheveningen.

Building numbers; 51 - 52 - 40 - 41 - 42

The B9 to  B 15 were the first self propelled bottom discharging hopper barges in the dredging industry and were equipped with a 225 BHP MWM engine. 

The B 9 - B10 - B11 and  B12 were build at shipyards in Groningen (NL)

The B14 was build at Worst & Dutmer in Meppel (NL)

The B15 was delivered by shipyard "De Liesbos" ( Amsterdamse Ballast Mij.) from Vianen (NL).

Off course the name "B13" was skipped, as sailing a vessel with that unlucky number was "not done" in the dredging world.

The  "Groningen" and "Utrecht" ( Building Nrs. 110-111) were build by Sleephelling Mij. Scheveningen and each of them was equipped with two MWM, 187 BHP engines.
