Abstract
An active, smartpipe stand (apparatus and method) for feeding and receiving pipe in a horizontal orientation to and from a pipe handling apparatus has a first pipe-lifting mechanism, a second pipe-lifting mechanism, and a pipe-rotating mechanism positioned between the first and second pipe-lifting mechanisms. The bottom of the first pipe-lifting mechanism is connected to the skid of the pipe handling apparatus. The bottom of the second pipe-lifting mechanism is connected to the skid of the pipe handling apparatus. The bottom of the pipe-rotating mechanism is connected to the skid of the pipe handling apparatus. Individual tubulars are unloaded, prepared, staged and sequenced, assembled and presented for delivery from horizontal to vertical. The pipe stand is positioned under the boom of the pipe handling apparatus when the apparatus is in the first position. The pipe stand extends within the skid structure.
