Dredging for the mega-ships
The fairway of the Lower and Outer Elbe is being deepened and widened for the world’s largest vessels. The Port of Hamburg therefore remains one of the world’s leading ports.
Last year’s starting signal for adjustment of the fair- way on the Lower and Outer Elbe was a vital step to- wards ensuring the port’s future. Several dredging craft have since been deployed on deepening and widening the navigation channel between the Port of Hamburg and the North Sea so that mega-container- ships and bulk carriers can use the Port of Hamburg very largely unhindered.
In the Port of Hamburg itself, the Hamburg Port Author- ity that is responsible for such work has already com- pleted it. On the adjoining section downstream, the
Vessels already benefit from the first navigational im- provements. The already completed construction of the ‘passing box’ between Wedel and Blankenese much simplifies encounters between especially wide ships. Once everything is finished, ships with a com- bined breadth of 104 metres will be able to pass. In this section, the navigation channel is 385 metres wide, compared to just 250 metres previously. Another important sub-project of navigation channel adjustment relating to the ‘passing box’: Provision of a new leading light line at Blankenese. This serves to
Construction of new front and rear leading lights
support navigation for incom- ing shipping. Construction of the ‘passing box’ has shifted the path for incoming shipping southwards. This correspond- ingly affects the sight axis of the leading line. HPA – Ham- burg Port Authority therefore needed to set up new ones. Crews of incoming vessels have been able to navigate us- ing the new tower since the end of October. The old lead- ing lights will be dismantled by next spring.
Further measures also include construction of a new inverted supply siphon for the radar
tower on the island of Nesssand in a deeper culvert. This project was completed over a year ago. In addi- tion, the slope on the East bank of the River Köhl-
