A method of decommissioning an offshore structure 502comprising a topside (504a, Fig 3a) mounted on a jacket (504b, Fig 3a) comprising rotating the offshore structure from a substantially vertical orientation to a substantially horizontal orientation as a single piece, for transportation to shore. Also disclosed is a barge 500 for decommissioning offshore structures comprising a support frame (504, Fig 3a) for supporting an offshore structure comprising a topside and a jacket. The support frame is mounted on the barge and configured to rotate between a loading configuration to facilitate loading of the barge with the offshore structure and a transport configuration to support the offshore structure during transport. The support frame comprises a first portion (506, Fig 3a) disposed at a first end of the support frame, the first portion configured to support the topside of an offshore structure; and a second portion (508a-d, Fig 3a) disposed between the first portion and a second end of the support frame, the second portion configured to support the jacket of the offshore structure.
