This patent describes an apparatus for use in inspecting, cleaning and/or performing other tasks in connection with a welded joint between intersecting tubular members of an offshore platform which are located a substantial depth beneath the water surface. It comprises a support body including a main portion having a throat in one side thereof so that it may be moved onto one of the tubular members whose peripheral end edge is welded to the other member, and means connected to the main portion for movement between outer positions to the side of the throat to permit the body to be moved onto or removed from the one member, and inner position tightly engaged with the one member for clamping the body thereabout, a carrier mounted on the support body for rotation thereabout and having a throat in one side thereof which, when the carrier is in a first rotative position, is generally aligned with the body throat to permit the carrier to be moved with the body onto or removed from the one tubular member. The carrier has means thereon for inspecting and/or cleaning the joint as the carrier is rotated into other positions about the body, and means responsive to the supply of power from a remote source for moving the clamping means between inner and outer positions, rotating the carrier about the body, and activating the means for inspecting, cleaning and/or performing other tasks in connection with the joint.
