The museum has a small section set aside to shipbuilding and mechanical engineering. Ships of metal have been built in Bergen since 1857, and Bergens Mekaniske Verksteder (BMV) was Bergen’s most important iron shipbuilders. Apart from models of Bergen-built ships and steam engines displayed throughout the exhibition, this part of the exhibition includes a model of a 26,000-ton (deadweight) ship under construction in sections. This was a building method introduced in great scale during World War II and which has continued ever since. The exhibitions also include a dominant model of an engine room from a freighter of around 8000 deadweight tons. An impression of the true size of such an engine can be made by a cylinder of a cutaway diesel engine from the M/S Hallanger (built in 1927).
