1 High Modifications Push Kness & associated structure / reinforcement

SNAME (Structure/Load) - (Robert Allan) Engineer and design fabrication drawings and fabricate pushing pads and structure upgrades for possible additions of transvers or longitudinal stringers and possibly spider webbing of trusses between to strengthen stern of barge to accept the Tug Seaway Guardians pushing knees to mate for pushing configuration and still allow for the use of the Robinson Bay and new HT-60 tug in the notch. Possible upgrades would include vertical doubler pads welded on stern to allow for wear of pushing knees, C-channel welded to sides of pushing pads to reduce side deflection and keep tug pushing knee pads centered on doubler pads, vertical deck structure to continue contact to tug pushing knees during all trim configuration of both vessels and to transfer force through all structure below deck. Below deck there may need to be additional gussets and deflection beams installed to transfer load to longitudinal deck and overhead stringers, any other structural additions that is engineered in to transfer load throughout structure. (See supporting pictures of below deck notch structure) (Adjust fixed stone ballast as needed for trim after steel structure added for knees and gangway) (Design and layout and selection of all associated deck fittings to moor Seaway Guardian, Robinson Bay and HT-60 vessels)(Update and modifications of drawings to show new structure and upgrades)
