Overview and history
2.5.5 Bremerhaven Overview and history
The Port of Bremerhaven is in northern Germany at the mouth of the Weser River. It is sixteenth-largest container port in the world and fourth largest in Europe. The container terminal is situated on the bank of the river opening to the North Sea. In the wet dock parts, accessible by two large locks, is one of Europe's largest RoRo terminals and industrial park.
The port's infrastructure and proximity to the North Sea have contributed to Bremerhaven's early engagement and ongoing participation in OSW projects.
The Port of Bremerhaven has supported several projects among them Germany's first OWF, Alpha Ventus, and the Nordsee Ost OFW.
Facilities used by OW sector
Port's existing quays were over repurposed and retrofitted by logistic companies over time to service specific projects and port is capable of handling both installation and fabrication activities for offshore wind turbines with capacities in the range of 6-10 MW. An overview of the main facilities dedicated to (or suitable for use by) OW projects are shown on Figure 2-34.

ABC Halbinsel is operated by BLG Logistics Solutions and has been used for both and production, transshipment and staging. Starting in 2011, after structural upgrades, 100 tripod foundations for Borkum West II were produced here in upright position. Since then, this terminal has also supported shipping out of towers, nacelles and other components. Not exclusively dedicated to OW, the
terminal is used for storage and shipping of all kinds of vehicles and heavy cargo. This terminal is located behind the lock.
Figure 2-35: ABC Halbinsel
The southernmost zone of the container terminal has been repurposed for staging (Nordsee Ost OWF), storage and transshipment of all OW components and can be seen in Figure 2-36. The main quay faces the open sea, with the Weser river shipping channel and is not restricted by locks. Further, it has a strengthened seabed to support jacking up.
At the back, behind a lock, there is a tide-independent quay which is backed by heavy load platform.

The main characteristics of the quays relevant for OW are summarized below in Table 2-.

By 2015, Bremerhaven had grown into a true offshore wind hub that hosts a diverse ecosystem of manufacturing facilities – foundations from WeserWind, blades from PowerBlades, offshore wind turbines from Adwen and both onshore and offshore wind turbines from Senvion - but since then, the port has been hit by closure after closure has left the it with no remaining manufacturing for offshore wind.
The first closure came in 2015, when the company WeserWind GmbH, which had occupied Lune hall at Labradorhafen for years and produced foundations, wind measurement masts and transformer units, declared bankruptcy.
In early 2018, after a decade in the port, PowerBlades closed its manufacturing there, due to a business decision to move the production to Portugal, where the labor costs were lower.
The closure of Adwen GmbH followed shortly thereafter in mid-2018. After being purchased from Areva by SGRE in 2016, the decision was made to consolidate servicing in Esbjerg. The presence at Bremerhaven has now been reduced to a service center.
In 2019, the last of the four offshore wind manufacturers at the port of Bremerhaven, Senvion GmbH, declared bankruptcy. The company was liquidated at the end of 2019 and the production site was closed.
A bright spot in manufacturing can be seen near the port of Bremerhaven on the left bank of Weser River, across from the planned offshore terminal, where the Steelwind Nordenham (subsidiary of Dillinger Huette) factory produces transition pieces and monopiles (output of up to 100 per year).
Factory is services by a dedicated 200m long quay with 6-10m LAT draught (tidal variation). Quay is designed for 1000 kN/m2 live load and is serviced by two static heavy-duty (800t) cranes able to work in tandem but does not support jacking-up in front of the quay. Laydown area is 18 ha.
The factory has produced 66 monopiles (up to 960t) for Merkur OWF (6MW turbines) during 2016 – 2017, wrapped up an order of 40 monopiles and 120 additional monopile sections for the Yulin Offshore Wind Farm off the coast of Taiwan in mid-2020 and recently received an order for 28 monopile foundations for the Arcadis Ost OWF in German waters.
In 2010, approaching the height of OW activity in the port, demand prompted the Senate of the Free Hanseatic City of Bremen to approve the plan for construction of new OW-specific trans-shipment facility on the Weser River. The proposed location (see Figure 2-37) offers both access to shipping channel unrestricted by locks and has 200ha of adjacent available estate (Luneplate) for future development of manufacturing facilities. Expected investment is 200 million euro.
Figure 2-37: Proposed location of new OTB (Luneplate industrial estate shown in blue) The planned extension, which is located in an environmentally protected area, has become mired in legal challenges and has lost political momentum. This loss of momentum was compounded with the recent loss of manufacturers at the port.
