​The South Harbour on Heligoland is set to undergo extensive refurbishment. This is part of the modernisation of the federal government’s fleet of multi-purpose vessels: the new specialised vessels are around ten metres longer than their predecessors and require modifications to the quay facilities.

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.

Ammunition in the port of Heligoland

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.

Restrictions on recreational craft

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.

Jill Grigoleit was born in Hanover in 1985. An early childhood memory is the large collection of YACHT and SURF magazines from her sailing and surfing enthusiast father. However, growing up in a small Swabian village on the Neckar, she had less to do with water sports in her childhood, apart from a few trips to the Baltic Sea with her family. After studying journalism in Bremen and Hanover, she went into television for a few years. Through a few lucky coincidences, she ended up on the water in 2011 and then returned to the written word professionally. For over ten years, she lived with her family on a houseboat in their own harbor south of Hamburg and wrote a book about houseboat building and life with children on the water. Since 2020, she has mainly been writing travel reports and features about people who live and work on and near the water for BOOTE. She has been a permanent member of the Delius Klasing water sports editorial team since January 2024.
