There are some museums in Stavanger and I would like to say a few words about the Oil museum. It might sound strange but Stavanger is the "oil capital" in Norway. Most of the major oil companies have their Norwegian office here in Stavanger and I guess this is the reason why Stavanger was the natural choice for the location of an oil museum. The oil industy has meant a lot to the development of Stavanger and Norway in general and this is an industry that has been going on for about 40 years now.
Once you get into the museum you are taken on a journey through history. What was Norway like when the oil was created? How do we the oil when it is located several thousand meters below the sea bed? How do we get down to the oil? What can we make out of oil? What is it like for people that work offshore of the oil riggs? What has the oil meant for Stavanger as a city and so on. And on the way you will find lots of exhibits of drillbits, models of offshore installations, different submarines/lifeboats and there is even a replica of a drill floor where you can take a look at the tools that are used when drilling.
I find this museum interesting but that might have something to do with the fact that I’m a petroleum engineer. :-)
You get a pretty good view of parts of Stavanger harbour if you go out on the roof of the museum. And if you get hungey there is a pretty good resturant called "Bølgen og Moi" inside the museum.
If you want more information there are two good links that I have found. The first is to the official pages: http://128.39.97.19/oljemuseum/uk/hovedframe.htm. The other one is http://stavanger.clickwalk.no/area/4e.html
