When did Bergen Mekaniske Verksted end?

Bergen Mekaniske Verksted (BMV) was nationalized in 1987 and became part of Kværner. Kværner itself went through several changes and reorganizations, eventually being acquired by Aker Solutions in 2006.

Therefore, while BMV itself ceased to exist as a separate entity in 1987, its legacy and some of its operations continued under Kværner and then Aker Solutions.

It's important to note that this isn't a single "end" date, but rather a series of transformations and transitions.
