In 2011, Svanemoellevaerket in Copenhagen needed renovation of their chimneys. One of the chimneys, which protrudes 101 meters above the quay, had large patches of rust which sent rust droplets onto the other chimneys – and at the same time onto the boats in the local marina, which could result in large costs for cleaning the boats.

Oersted therefore decided to have all the chimneys washed down and at the same time to have the surface of the rusty chimney renovated.

All surfaces were washed down with a solution to remove the rust. There was only one method for this job – hands on! The damaged parts of the rusty chimney were ground down and subsequently surface treated. After this treatment, Oersted had a five-year guarantee on the surface treatment of the chimney.

During the work period of six weeks, there were four rope access technicians working on the chimneys every day.


The task was solved within 6 weeks.
