Svitzer Mjølner: 28 wheelhouse windows restored after 15 years at sea
After about 15 years in service, the wheelhouse windows on the tug Svitzer Mjølner were covered in mineral deposits, sea salt and chemical residues. In April 2024, while the tug was in dock II at Assens Skibsværft, we restored all 28 wheelhouse windows in about four days and protected them with a 2-year glass coating.

We removed the deposits and polished all 28 wheelhouse windows while the tug was in dock II – about four days of work.
The result
The windows came out like new and are protected with a 2-year glass coating that makes them easier to keep clean.
