Abstract:
A racking board for retaining tubulars is disclosed having a first finger, a second forger positioned generally parallel to the first finger and with a gap between the fingers serving as a storage area for tubulars. A first inflatable member is supported adjacent to the first finger and a second inflatable member is supported adjacent to the second finger, the inflatable members adapted to expand radially into the gap upon inflation so as to capture and retain the tubular. In some embodiments, a single inflatable member in employed to expand into the gap and retain the tubular. A method of racking tubulars is disclosed using elongate, inflatable restraints.
