Mammoet designed a bespoke gantry system with a capacity of 900 tonnes to life four tunnel boring machines out of a shaft above underground tunnels for the HS2 high-speed railway in the UK. Mammoet extracted the TBMs from the Green Park Way vent shaft, 35m above the twin tunnels, on a difficult site on the outskirts of London that sits near two live railways. Collaborating with contractor Skanska Costain Strabag JV and TBM manufacturer Herrenknecht, Mammoet extracted the front and middle sections of each TBM in a single lift and placed them onto SPMTs, transporting them to a disassembly area on site. Design of the system took nine months and each of the four lifts took 24 hours. (Image courtesy of Mammoet).

A drone view shows rotor blades and other parts for the ongoing construction of the Revolution Wind offshore wind turbine farm, staged on the State Pier in New London, Connecticut, USA. The Revolution Wind project, which is a joint venture between the Danish company Orsted and Skyborn Renewables, is located 15 miles off the coast of Rhode Island and is 80% complete with all offshore foundations in place and 45 of 65 wind turbines installed. Earlier this month, a federal judge ruled that Ørsted can restart the nearly-complete project after Revolution Wind sought a temporary injunction to lift a stop-work order issued by the Trump administration on 22 August.
