The construction phase started on 1 September 2016 by disposing dredged sediment from the harbour basins of the Port of Harlingen to the new disposal location.
In the period 1 September 2016 to 31 March 2017 in total 300,188 m3 of dredged sediment was disposed in the new disposal location. In a second season, from 1 September 2017 to 1 December 2017 a total of 170,328 m3 was disposed. The mud was dredged from the harbour basins of the Port of Harlingen using a 604 m3 Trailing Suction Hopper Dredger named ‘Adelaar’ of the company De Boer Dredging.
Dredging operations were carried out daily during weekdays and weekend days, between 07:00 h and 19:00 h. The average cycle time was around 1:45 h. The realised number of mud disposals was dependent on appropriate high tides inside the available time window, and on other factors such as weather conditions and technical problems. An average number of approximately 22 mud disposals per week, with a weekly volume of 13,288 m3 was achieved.
