Widening MSC Geneva

According to NSB, the widen- ing method is a perfect option to enhance the competitive edge of older vessels as it increases the TEU capacity of modi? ed units by more than 20% while operating costs re- main the same. The Widening is easy to see with the naked eye, while the bene? ts and cost ef? ciencies are as readily evident to the shipowner.
