WSV finally took delivery of its new large hopper dredge
Osteriff in December.
The ship was ordered in late 2016 from Pella Sietas and was originally planned to be commissioned in December 2018. Officially there were then delays in procuring equipment - unofficially delays were because the shipyard didn't pay for dredging out the river sludge and thus couldn't launch the ship as it couldn't lower the pontoon it was sitting on. Construction "continued" until the shipyard went bankrupt for a second time in 2021 and finally folded. End of 2022 WSV contracted Blohm+Voss (NVL) to complete the semi-finished ship. Due to this history cost increased from 95 million to 142 million Euro. Sea trials were conducted October to November 2025, federal flag hoisted on Dec 17th.
Osteriff will be stationed in Wilhelmshaven next to the Bundeswehr's main naval base and - among other similar tasks - is used for dredging the seaside path to the base to maintain its accessibility. She'll also be used in the Weser and Elbe estuaries, although especially in the Elbe dredging is mostly contracted out. Osteriff is a 133m long mid-sized commercial-design hopper dredge with about 12,000 tons / 7,500 m³ transport capacity and facilities for 24/7 two-watch operations - for which WSV also maintains two crews for her.
Pella Sietas built two other ships of the same design for a German company before. Both now operate for other owners around South-East Asia and Australia. Offhand one is being used in an ongoing decade-long contract to dredge at the port of Melbourne.
WSV operates an older hopper dredge of near-identical size -
Nordsee - and was originally planning to operate both in parallel. In particular the commercial dredging industry is pushing for WSV to retire
Nordsee (and contract them instead). This is somewhat unlikely since a) WSV tends to retain older ships until no longer viable to run and b)
Nordsee was rebuilt in the 80s to also support pollution control operations.
