Mammoet has secured the heavy lifting contract from Saipem for the construction of the Beccs Stockholm carbon capture project in Sweden, marking another major step forward for large scale decarbonization infrastructure in Europe.
The Beccs Stockholm facility, owned and operated by Stockholm Exergi, is expected to become one of Europe’s first major carbon capture and removal plants. Once operational in 2028, the site will capture and permanently store 800,000 tonnes of biogenic CO₂ annually from Stockholm Exergi’s combined heat and power plant. The project is supported by the European Innovation Fund and the Swedish government.
Under the contract, Mammoet will perform the lifting of approximately 23 components weighing between 50t and 280t, alongside two major units weighing around 1,500t each. The stripper and absorber units will be installed using Mammoet’s PTC 140 DS, one of the world’s largest land based ring cranes.
The 3,200t class crane, capable of lifting up to 5,000t, will work in combination with a 1,250t crawler crane to upend the massive components from a horizontal position delivered by barge before final installation. Additional crawler cranes ranging from 300t to 800t capacity will support assembly operations and secondary lifts on site.
According to Pieter van der Weele, Senior Project Manager at Mammoet, strict scheduling will be critical to the project’s success. The company has only four weeks to assemble the 150m tall PTC crane, followed by a four week installation window and a six week dismantling period to release the construction area for the next phase of plant development.
The PTC 140 DS is scheduled to arrive in Stockholm in April 2027, where its assembly near the city centre is expected to become a major visual milestone for the landmark carbon capture project.
