On Site Line Boring Machining Project—Marine Pipe Laying Barge Retrofit
Furmanite was recently awarded a contract to perform on site line boring on the new construction retrofit of a Marine Pipe Laying Barge. The barge was being fitted with a new pipe spool and arm braking system. The 9” x 6” brake arm pin bores were set in a series of five pad eyes each with a forty inch span from left pad to right pad with the corresponding set of pads on the opposite side of the spool, totaling a thirty foot span from the outside pad starboard side to outside pad port side. The tolerances required were +/- 0.001” in concentricity and diameter over the entire thirty foot series of bores.
