Definitions
- the invention relates generally to ocean push towing and more particularly to an apparatus and method for rigidly joining and rapidly separating a push type tug and a barge having an indented stern.
- FIGURE 1 is a side view of the tug and barge in joined conditions with the receiving part or slip of the barge and a part of the tug shown in phantom,
- FIGURE 2 is a plan view of FIGURE 1 showing tug rubbing fenders engaged in barge channels, and
- FIGURE 3 is a cross-sectional view along section lines 3--3 of FIGURE 2.
- the barge is provided with a deeply indented stem 12 defining a slip 14 for engaging a tug 16- at least beyond the tugs center of gravity 17.
- the indented sides 18 and 20 defining the slip are oppositely serrated to provide a plurality of parallel longitudinal channels 22 spaced vertically apart above the water line.
- the tug 16 is a usual pusher type having port and starboard rubbing fenders or strakes 24 extending longitudinally adjacent the bow 26 to well aft of the center of gravity 17 of the tug. These rubbing strakes 24 extends longitudinally with the deck 28 and project laterally beyond the sides 30 of the tug and are cooperatively sized to fit in the channels 22 defined in the sides of the slip 14.
- the tug To engage the tug with barge for push towing the tug is driven by its propeller 32 slowly into the indented slip 14 to engage a pair of opposing parallel channels 22 0 "lee on each side thereof with its rubbing strake 24, the engaged channels 22 being the ones engageable in accordance with the relative drafts of the barge and the tug.
- the tug When the tug is fully engaged in the slip 14 it is rigidly attached to the barge by its rubbing strakes and the two vessels in effect become one for push towing.
- FIGURE 3 illustrates the engagement of the strakes in the upper channels 22 of the slip 14.
- the tug may be secured in the slip 14 by means of lines 36 fastened to and around bollards 34 and to quick release means 38.
- An improved marine push towing combination comprising a tug having a bow, a center of gravity, and sides; rubbing strakes attached to each side of said tug and extending longitudinally from adjacent said bow to abaft said center of gravity and transversely beyond said tugs sides; and a barge having a stern indented longitudinally for at least more than the distance from the bow to the center of gravity of said tug and transversely for not less than the width of said tug, the longitudinal side of said indented stern defining a plurality of vertically spaced opposing pairs of longitudinally extending channels, receiving in one said pair, dependent on the relative drafts of tug and barge, said rubbing strakes, whereby said mg is rigidly joined onto said barge for forward travel with said rubbing strakes engaged in a pair of said channels and rapidly separated therefrom when said tug backs down out of said indented stern.
