From 1 April 2023, Försäkringskassan will expand at Wihlborgs' Kranen 8 property in Dockan by 3,000 m². At the same time, the lease will be extended by six years. In 2016, Försäkringskassan decided to co-locate several of its operations at Wihlborgs' Kranen 8 property.

As of next year, Försäkringskassan will move additional operations in to its premises so that the total lease encompasses 15,000 m². In connection with the expansion, the lease will be extended by six years. Kranen 8, which is Kockum's old 1960s submarine hall, has been converted into a modern office environment housing restaurants, an auditorium and a penthouse for meetings and conferences.

The building has been certified to Miljöbyggnad Silver.
