摘要：
A method of servicing a pipe bundle or riser bundle employs a specially configured hoist having a rail that supports multiple lifts. A selected satellite pipe/conduit of the pipe bundle is both lifted and pulled horizontally in order to remove it from a plurality of supports that hold the satellite pipes together in spaced apart positions. During removal of a satellite pipe, the lifts elevate, then travel with and hold the pipe as it moves horizontally away from the bundle.
