A century of KOTUG history
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. In 1934 a third tug was bought: ‘’Brabantia’’ (later renamed ‘’Antonie’’). Adriaan Kooren registered ‘Towage Company Adriaan Kooren BV’ in 1934. He started out as an independent towage broker to become a tug owner, employing the tugs in the dredging and (port) construction industry in Rotterdam.
During the 2nd World War, the Kooren family managed to save their tugs "Frans" and "Adriaan".
After the war, Antonie Kooren and his 5 sons joined forces and started their own tug boat company. As partner in this venture, Adriaan settled in a wooden office at the ‘’Boompjeskade’’ in Rotterdam.Read more
