The roots of KOTUG (four generations family Kooren) go back to the initial activities of Antonie Kooren, when he built his first tug in 1911.

After working for ‘‘Stoomsleepdienst Maas” and “Rotterdamse Sleepdienst”, Antonie decided to set up his own company. He bought a tug “Corrie” in 1919 and from that moment on, the white “K” emblem on the funnels was a fact. These tugs were mainly used for towage and dredging.

By this time, Antonie’s son Adriaan had registered as an independent towing agent, working mostly in offshore and dredging. This also provided employment for his 5 brothers.
