Today the news was made public that in February steamship Rotterdam will leave for Gdansk in Poland. Since November 25 last year the ship is in drydock in Cadiz for restoration of the exterior and painting. Work will be ready at the end of this month. The Rotterdam will have her grey hull again. It is expected that the Rotterdam will stay in Gdansk for at least six month.
Before the restoration of the interior of the ship can start, the ship will be made asbestos free and  safe. Much attention will be paid to restoring the lounges and cabins in their original state, answering to today's needs of comfort and safety. Heating, electricity, sound-isolation and sanitary will be renewed. Elevators and cabins will be restored while keeping the historical elements. Air-conditioning will apply to the Dutch climate. Also fire alarms and sprinklers will be renewed so the ship will have a high degree of safety.
Several European shipyards were considered, because the job to be done is complex and a lot of highly qualified workers are necessary. In the end Gdansk offered the best opportunities. The Polish partners are delighted to be able to contribute to the restoration of steamship Rotterdam. Please also visit www.derotterdam.com.
