Construction of a New Boiler Plant: Installation of Steam Boilers and Hot-Water Boilers
The Seeland team was commissioned with the installation of two steam boilers and two hot-water boilers as part of the construction of a new boiler plant in Neumünster. In order to ensure quick unloading and rapid lifting of the two 85 t and 10 m long hot-water boilers and two 74 t and 8 m long steam boilers, the Gustav Seeland GmbH team used innovative implementation solutions and modern, tried-and-tested assembly equipment. In addition, a 400 t special crane, proprietary lifting gantry equipment and a 100 t telescopic crane were used. For the efficient execution and optimal preparation of the assembly project, Gustav Seeland supported its customer with a full-service solution.
In cooperation with the client, Seeland engineers developed a professional and individually tailored concept including risk assessment, crane construction planning and footprint planning, feasibility studies, transport and assembly studies and precise 3D CAD visualizations. After a successful planning phase and the creation of graphical visualizations of all the individual processes, the second step was to define the processes for the entire Seeland team.
Transformer Replacement in the Heart of Eimsbüttel
The Gustav Seeland GmbH team were faced with a challenging transformer replacement at the substation on Ottersbekallee in Hamburg-Eimsbüttel. As part of the assembly project lasting several days, an old transformer with a weight of approx. 72 t was extracted and removed, and the new transformer weighing 81 t was delivered and installed. Due to limited space in the middle of the idyllic residential area, it was necessary to relocate the respective transformer on the road in front of the substation using proprietary lifting gantry equipment.
The SCCP-certified Seeland assembly team carried out the removal and installation of the transformers. To meet this challenge, Gustav Seeland used proprietary special equipment as well as its own vehicles and mobile cranes. All the significant preparation for the project was also managed by the Seeland team.
After Dismantling, the New Belt Conveyor Galleries are installed
After the Seeland team had efficiently and professionally dismantled the two belt conveyor galleries destroyed by a fire, the new ones were assembled a few months later. The two gallery segments, which are up to 34 m long, were custom-made with special dimensions and professionally assembled by the 12-person Seeland team at a combined heat and power plant in Hamburg. With the help of two 100 t cranes, the new galleries were first lifted from the storage area to the trailer provided for this purpose and relocated internally.
Subsequently, the two 43 t structures were lifted one after the other by two 220 t cranes in a tandem lift and quickly and safely assembled by the respective Seeland team. The project was carried out on four consecutive days and completed on time thanks to the 3D CAD visualization created in advance by Gustav Seeland GmbH.
Installation of Three Heat Pumps Drives Forward Climate Protection in Hamburg
Thanks to the professional assembly, installation, and alignment of three 52 t and 9 m long absorption heat pumps in a Hamburg waste incineration plant, the exhaust air there can be used for district heating in the future. As a result, as of the end of the year, it will be possible to heat around 35,000 apartments without polluting the environment with additional combustion of coal or gas.
The Seeland team was able to actively support this energy project, which is unique in Germany and funded by the EU, for two weeks. With its own 150 t mobile crane, a skidway, electric chain hoists, and other special equipment, the Seeland assembly team initially securely and quickly installed the three new steam-powered absorption heat pumps and aligned them the following week using its own lifting gantry equipment. As part of the preparation, the upper and lower parts of the pump were temporarily stored by Gustav Seeland GmbH and transported to the construction project in a just-in-time approach.
360° Service for the Removal of Two Belt Conveyor Galleries
In this project, Gustav Seeland was commissioned by a customer in a Hamburg combined heat and power plant to initially dismantle two old belt conveyor galleries and to add new galleries at a later date. The structures, measuring up to 34 meters in length, were damaged by fire and had to be replaced. The task was to move maximum loads of 43 metric tons at a height of 36 meters with the utmost precision.
For optimal preparation and efficient implementation of their project, Gustav Seeland provided the customer with 360° support. In cooperation with the customer, the engineers developed a professional, individualized concept including feasibility studies and risk assessments, crane superstructure and parking space planning, transportation and installation studies, and 3D CAD visualizations. This planning is an integral part of the “Engineering” service that Gustav Seeland now offers. In the second stage, the meticulously defined processes were implemented. The first, front belt conveyor gallery was divided into two parts and lifted down by two 220-metric ton cranes in a tandem lift. The cranes managed the second belt conveyor gallery in one go. The three gallery segments were transferred internally by Seeland. A heavy-duty trailer was used for the transportation. Two 100-metric ton cranes, also provided by Gustav Seeland, then unloaded the belt conveyor galleries in the designated storage space. The Seeland team on-site was represented by a total of 15 employees.
Disassembly of two water tanks
Two water tanks with a diameter of 2.72 meters and 5 meters in length had to be replaced in a thermal power station. The challenge for Gustav Seeland's assembly team was to lift the two 1.3-ton and 1.8-ton tanks within a very cramped hall, move them out and bring in the new tanks. The heavy lift experts used an electric crane and two half-shells with roller dollies to lift, outsource, position and adjust the heavy objects.
With the use of the CO2-neutral Pick & Carry crane, the work inside the hall could be carried out silently and with low emissions. Due to the space available and the narrow entrance and exit, the water tanks were placed horizontally lengthways and brought into position for removal. The new tanks were installed within two days. Precise planning in advance was necessary for the implementation of the project.
Transport and assemble of the Miniatur Wunderland Walkway
Gustav Seeland has been awarded a contract to transport and assemble a footbridge in Hamburg’s historic Speicherstadt warehouse district. The walkway will connect Miniatur Wunderland’s exhibition areas, which are located in two former warehouse buildings facing each other. The tourist attraction plans to enlarge its exhibition space and make it possible for visitors to access the two buildings via the new bridge. The steel-and-glass construction—which has been built by bridge specialist—measures some 25 meters in length and weighs 38 metric tons.
Gustav Seeland has been tasked with transporting the footbridge to the Speicherstadt warehouse district and installing it on-site, as well as with all logistics services connected with project execution. These included a feasibility study taking into account local conditions, the commissioning of geostatic reports, and the procurement of the permits required to transport the bridge.
A large, 750-metric ton crane—which itself needs to be erected using a 100-metric ton crane—will be used to assemble the footbridge. Seeland will be deploying twelve ballast vehicles, with a length of 18 meters and counterweights totaling 204 metric tons, to erect the large crane
Heavy Lifting for the Construction of the New Bille Bridge
In order to ensure rapid demolition of the 100 years old bridge, the Gustav Seeland Team intends to deploy two special cranes – each with a load-bearing capacity of some 220 metric tons – and a 60-metric ton brake car with a tractive force of 80 metric tons. The lifting mast of the 500-metric ton crane will be assembled on the crane pontoon from dry land. Gustav Seeland will be assigning twelve heavy-goods and assembly specialists, with the requisite expertise, to handle the project.
Relocation of an aircraft segment
Precision work was required from the Gustav Seeland Team when relocating a 19 meter long and 9 tons aircraft segment. With the help of the Palfinger "Optimus" (PK92002-SHG with PJ 125E) loading crane, every corner in the hall could be optimally used and guaranteed a safe and quick implementation of the project.
Replacement of Two Driveshafts
To enable the replacement of two 40-metric-ton driveshafts at an aluminum plant, Gustav Seeland developed a new steel construction during a four-week planning phase, with the size and weight of the transportation equipment and the weight of the driveshafts playing a vital role. Other factors included structural integrity and the limited space available.
In order to handle the project, the company not only deployed the steel construction, but also two masts (360 t, 160 t), a crane traction truck, a 70-metric-ton crane, and a semitrailer with a 6 × 4 Arocs traction unit.
Transport and installation of the new Skywalk U4
Gustav Seeland was contracted with transporting and mounting a new pedestrian bridge in Hamburg. The bridge elements, produced by Lamparter in Hessisch Lichtenau, weigh between 75 and 120 tons each.
The contract of Gustav Seeland comprises everything from planning through to execution of all the logistics services in connection with the bridge project. This includes checking the feasibility, obtaining the necessary permissions, the transport itself, and positioning the bridge elements.
For this, the bridge parts already prepared at Hamburg’s Pella Sietas shipyard will be taken to Baakenhöft on a dock pontoon and then to Elbbrücken on heavy-haulage trailers. Loading will involve a mobile 500-ton crane and 700-ton crane. The transport from Lamparter‘s steelworks in Hessen to Pella Sietas shipyard in Hamburg was already carried out on heavy-haulage trailers by road.
Relocation of the Holsten brewery
The Holsten brewery has commissioned Gustav Seeland to plan and carry out the relocation of fermentation tanks from Atlona to Hausbruch, where regular operation is scheduled to start in April 2019. With a weight of up to 35 tons and a length of up to 24 meters, the tanks contain half a million liters of beer.
Gustav Seeland was responsible for the lifting, loading, transport and intermediate storage of the individual fermentation tanks. The individual tanks were lifted out of the brewery using a 700-ton crane and loaded onto a 40-meter-long low loader. Thanks to the use of the seven-meter-high low-loader, many logistical measures had to be carried out in advance, such as turning traffic lights, pruning trees and setting up extensive road closures.
