Focus 30 crane completes first project
By Niamh Marriott05 October 2021
Mammoet has completed the first lift using the first unit of its Focus 30 crane, performing a top-and-tail lifting operation in tandem with a 500 tonne mobile crane, to install a vessel at a refinery in the UK.
The Focus 30 is designed to deliver significant lifting capacity at complex sites. As it is erected vertically in sections, the crane requires no laydown area during assembly of its boom. It can be built away from active plant, and less infrastructure must be disrupted or closed during its use.
The company explained that a conventional crawler crane would need to be built over a nearby pipe rack and cause a site road to be temporarily closed for a number of days but the Focus 30 was manoeuvred in sections around key infrastructure and its boom was raised within the area of the crane’s own footprint, reducing disruption.
Journey to site
Mammoet transported the new vessel 3 kilometres from a local port using 36 axle lines of SPMT. It was then positioned in a staging area so that the transport arrangement could be reconfigured to suit onsite requirements.
To facilitate the onsite route, a bespoke ‘book end’ transport frame was used, alongside the hydraulic stroke of the transporters themselves, to navigate the vessel under a number of low pipe racks. Once it reached its installation location, the Focus 30 and a 500 tonne mobile crane were used in tandem to lift the vessel and set it securely on its foundations.
