FROM CONSTRAINED SITE TO CLEAN REMOVAL
After precise planning, we defied the cramped conditions of the site and removed a 94t choke coil and the associated radiator for our client. Our specialists from the assembly team were supported by a 500t mobile crane for the removal of the element.
The scope of the order also included transport to the disposal site. Our drivers safely steered our “love boats” with radiator and choke coil in tow to the disposal port using a 3-axle semi-trailer truck and a 4+6 low-bed combination.

CONSTRUCTION OF A BOILER PLANT
SEELAND was commissioned to install two steam boilers and two hot water boilers in a new boiler plant in Neumünster. To ensure rapid unloading and swift lifting of the two 85t, 10m long hot water boilers, as well as the two 74t, 8m long steam boilers, the SEELAND team used innovative implementation solutions and modern, tried-and-tested assembly equipment. A 400t mobile crane, the company's own lifting equipment, and a 100t mobile crane were also utilized. SEELAND supported the client with a full-service package to ensure the efficient execution and optimal preparation of the assembly project.
SEELAND engineers worked with the client to develop a professional and individually tailored concept, including risk assessment, crane assembly and positioning planning, feasibility studies, transport and assembly studies, and precise 3D CAD visualizations. After a successful planning phase and the creation of all graphic visualizations of the individual processes, the procedures were defined for the entire SEELAND team, followed up with the installation of the boilers.
TRANSFORMER REPLACEMENT IN THE HEART OF HAMBURG
SEELAND recently carried out a challenging transformer replacement at the substation on Ottersbekallee in Hamburg-Eimsbüttel. The installation project, which took several days, involved removing an old 72t transformer, transporting it away, and then transporting and installing a new 81t transformer. Due to limited space in the middle of the idyllic residential area, it was necessary to transfer the respective transformers on the street in front of the substation premises using our own lifting equipment.
The SCCP-certified SEELAND assembly team carried out the removal and installation of the transformers in a professional manner. To meet this challenge, SEELAND used its own special equipment such as lifting frames, vehicles, and mobile cranes. All preparations relevant to the project were also managed by SEELAND.
INSTALLATION OF CONVEYOR BELT BRIDGES
After SEELAND had efficiently and professionally dismantled the two conveyor belt bridges that were destroyed by fire, the new ones were installed a few months later. The two bridge segments, which were up to 34m long, were custom-made with special dimensions and professionally installed by the twelve-member SEELAND team at a combined heat and power plant in Hamburg. With the help of two 100t mobile cranes, the new bridges were first lifted from the temporary storage area onto the designated semi-trailers and transported within the company.
The two 43t structures were then lifted one after the other by two 220t mobile cranes in tandem and quickly and safely installed by the SEELAND assembly team. The project was carried out over four consecutive days and was completed on schedule thanks to the 3D CAD visualization created in advance by SEELAND.
SUSTAINABLE HEATING FOR 35,000 HOMES
Thanks to the professional installation, delivery, and alignment of three 52t, 9m long heat absorption pumps in a waste incineration plant in Hamburg, the hot exhaust can now be used for district heating. As a result, from the end of the year, around 35,000 homes will be able to be heated without polluting the environment with additional coal or gas combustion.
SEELAND was able to actively support this nationally unique and EU-funded energy project for two weeks and promote climate protection. Using our own 150t mobile crane, a transfer track, electric chain hoists, and other special equipment, our installation team safely and quickly installed the three steam-powered heat absorption pumps, and then aligned them the following week using our own lifting frame. As part of the preparations, the upper and lower parts of the pumps were temporarily stored by SEELAND and transported to the construction site.
360° FULL SERVICE AFTER FIRE DAMAGE
In this project, SEELAND was tasked with dismantling two old conveyor belt bridges for its client at a combined heat and power plant in Hamburg and then reinstalling new bridges at a later date. The structures, which were up to 34m long, had been damaged by fire and needed to be replaced. The task was to move maximum loads of 43 tons at a height of 36 meters with pinpoint precision.
SEELAND provided the client with comprehensive support to ensure optimal preparation and efficient implementation of the project. In collaboration with the client, our engineers developed a customized and professional concept including feasibility studies and risk assessments, crane assembly and footprint planning, transport and assembly studies, and 3D CAD visualizations. This type of planning is part of the “engineering” service that SEELAND offers in-house. The second step was to execute the meticulously planned procedures. The first, front conveyor belt bridge was divided into two parts and lifted by two 220-ton mobile cranes in tandem. The cranes handled the second conveyor belt bridge in one piece. The three bridge segments were moved internally by SEELAND. A heavy-duty roller (semi-trailer) was used for transport. Two 100-ton mobile cranes, also provided by SEELAND, then unloaded the conveyor belt bridges onto the designated storage area. The SEELAND team on site consisted of a total of 15 employees.
DISMANTLING OF WATER TANKS
Two water tanks with a diameter of 2.72m and a length of 5m had to be replaced in a combined heat and power plant. The challenge for the SEELAND assembly team was to lift the two tanks, weighing 1.3t and 1.8t, within a very confined hall, remove them, and install the new tanks. The heavy goods experts used an electric crane and two half-shells with tank rollers to lift, remove, position, and fit the heavy objects.
The use of the CO2-neutral Pick & Carry crane meant that the work could be carried out quietly and with low emissions inside the hall. Due to the space constraints and the narrow entrance and exit, the tanks were laid down horizontally lengthwise and moved into position for transport. The new water tanks were installed within two days. Precise planning in advance was necessary to implement the project.
TRANSPORT AND INSTALLATION OF THE MINIATURWUNDERLAND BRIDGE
SEELAND was contracted to transport and install a pedestrian bridge in Hamburg's Speicherstadt warehouse district. The bridge connects the old and new exhibition areas of Miniatur Wunderland, which are located in two warehouses opposite each other. The Hamburg tourist attraction wanted to expand its exhibition space and give visitors the opportunity to reach the warehouse buildings via the new crossing. The steel and glass structure, manufactured by bridge specialists, is around 25m long and weighs 38t.
SEELAND's contract included the transport to and installation of the pedestrian bridge at Hamburg's Speicherstadt, as well as all logistics services related to the project. This also included assessing the feasibility of the project in terms of local conditions, obtaining geostatic reports, and procuring the necessary permits for transporting the bridge.
A large 750t mobile crane was utilized to assemble the pedestrian bridge, which was erected with the help of a 100t telescopic crane. The SEELAND team used 12 ballast vehicles with a length of 18m and counterweights totaling 204t to erect the large crane.
DISMANTLING OF THE HAMBURG BILLE BRIDGE
To ensure rapid dismantling of the over 100-year-old railway bridge, the SEELAND team deployed two special cranes, each with a load capacity of around 220t, and a 60t brake car with a pulling force of 80t. The lifting mast for the 500t mobile crane will be assembled on the floating pontoon from the land side. SEELAND is providing 12 heavy-lift and assembly specialists to carry out the work.
RELOCATION OF AN AIRCRAFT SEGMENT
The relocation of a 19m long, 9t aircraft segment in Hamburg required precision work from the entire SEELAND team. With the help of the Palfinger “Optimus” loading crane (PK92002-SHG with PJ 125E), every angle in the hall could be optimally utilized, thus guaranteeing the safe and rapid completion of the project.
REPLACEMENT OF TWO DRIVE SHAFTS
SEELAND developed a new steel structure in a four-week planning phase for the replacement of two 40t drive shafts in an aluminum plant. The size and weight of the transport equipment and the weight of the drive shafts played a decisive role in this project. The limited space available and the structural integrity of the shafts were taken into account.
To complete the job, the company used two lifting frames (360t, 160t), a crane tractor, a 70t mobile crane, and a semi-trailer with a 6x4 Arocs tractor in addition to the steel structure.
TRANSPORT AND INSTALLATION OF THE NEW U4 ELBE BRIDGE
SEELAND was commissioned to transport and install a new pedestrian bridge in Hamburg. The bridge elements, manufactured by Lamparter in Hessisch Lichtenau, weigh between 75 and 120t.
SEELAND's contract covered all logistics services related to the bridge construction project, from planning to execution. This includes feasibility studies, obtaining the necessary permits, and transporting and installing the bridge elements.
The bridge parts prepared at the Pella Sietas shipyard in Hamburg were transported to Baakenhöft on a dock pontoon, and then on to the Elbe bridges on heavy-duty trailers. A 500t and a 700t mobile crane were used in tandem for loading.
HOLSTEN BREWERY RELOCATION
The Holsten Brewery commissioned SEELAND to plan and execute the relocation of fermentation tanks from Altona to Hausbruch, where regular operations commenced in April 2019. Weighing up to 35t and measuring up to 24m in length, the tanks hold half a million liters of beer.
SEELAND was responsible for excavating, loading, transporting, and temporarily storing the individual fermentation tanks. A 700t mobile crane was used to lift the individual tanks out of the brewery building and load them onto a 40m long low-loader. The use of the flatbed trailer, which was seven meters high in total, required many logistical measures to be carried out in advance, such as turning traffic lights, pruning trees, and setting up extensive road closures.
