The federal government’s multi-purpose vessels carry out numerous maritime emergency response tasks. Among other things, they are equipped to deal with oil spills, have specialised tank systems for hazardous liquids and an on-board laboratory for analysing pollutants. In addition, they can secure distressed vessels using high-towing capacity and are equipped with a helipad. The quays in Heligoland’s South Harbour now need to be adapted to accommodate the new, significantly larger vessels.
According to the Elbe-North Sea Waterways and Shipping Authority (WSA), work has already begun. The breakwater is being extended and reinforced against scouring, and the harbour basin is also being deepened. The next step will be to rebuild the southern breakwater. The actual expansion is expected to begin in spring 2027. According to the WSA, this phase of the project alone will cost tens of millions.
Before construction work can begin, it must first be established whether there are any unexploded ordnance remaining on the future building site. Due to its history, Heligoland is still considered to be heavily contaminated with munitions. The Waterways and Shipping Authority has therefore issued a call for tenders to survey the harbour area.
For water sports enthusiasts, the situation in the South Harbour and the outer harbour has already changed significantly in recent years. Large sections of the South Quay and the outer harbour are now permanently occupied by crew transfer vessels and support vessels serving the offshore wind industry. The outer harbour now serves primarily as a transit area; anchoring is generally prohibited there. In addition, diving work takes place regularly, and construction work on the pier occasionally results in further restrictions.
