Trondhjems mekaniske Værksted or TMV was a major shipbuilding company in Trondheim, Norway.
Weidemann resigned from his managerial position in 1871 and founded Trondhjems mekaniske Værksted the following year.
The former location of the company's shipbuilding business is still referred to as TMV by some citizens of Trondheim.
Solsiden shopping centre was built on the grounds in October 2000, and the surrounding area now has several apartment buildings and a hotel.
The history of the area as a shipyard is preserved; the dry docks, many of the company buildings, and even some of the shipbuilding equipment (such as a large crane) is still present.
