Mammoet awarded contract by Saipem
Mammoet, the global leader in engineered heavy lifting and transport, has been awarded a contract by Saipem to carry out the heavy-lift scope for the construction of Beccs Stockholm – one of Europe’s first large-scale projects for carbon capture and removal.
Bioenergy with Carbon Capture and Storage (BECCS) is a method for permanent carbon removal, by capturing carbon dioxide (CO₂) from biogenic emissions at a combined heat and power plant and storing it underground.
When ready in 2028, the Beccs Stockholm plant will capture and store 800,000 tonnes of carbon dioxide annually from the biogenic flue gases of Stockholm Exergi’s existing combined heat and power plant. The plant will see Stockholm becoming one of the first cities in the world to capture biogenic CO₂ on a large scale.
The site is owned and operated by Stockholm Exergi and the project has been part funded by the European Innovation Fund and the Swedish government.
Mammoet will support with the lifting of around 23 components weighing between 50t and 280t, and two larger components – the stripper and absorber – weighing around 1,500t.
These two heaviest items will be lifted by one of the world’s largest land-based cranes – Mammoet’s PTC 140 DS – a 3,200t class ring crane that can lift weights of up to 5,000t. They will be delivered to the site on a barge horizontally, before being orientated to a vertical position using a 1,250t crawler crane and the PTC crane prior to installation.
Several other crawlers, ranging from 300t to 800t, will also be on site to support the assembly of the main PTC crane and lifting of the smaller components.
As the PTC must be assembled on an area reserved for the build, Mammoet must assemble and disassemble the crane within a short timeframe.
Pieter van der Weele, Senior Project Manager at Mammoet, said: “Timing and planning are essential for this build. We have just four weeks to assemble the PTC, which will be achieved with two teams working in two shifts.
The installation stage is also a window of four weeks, and then we must break the crane down again in six, freeing up the area so that it can be used to build the remainder of the plant”.
Mammoet will take the PTC 140 to Stockholm in April 2027 and will begin assembling the 150-meter-tall crane. With the project site close to Stockholm city center, residents will be able to witness its role in the construction of this landmark decarbonization project.
