murphy pacific marine built the "marine boss" floating barge-crane in 1966 with a capacity to perform the heavy box girder and deck-section lifts. the heavy lift capacity of "marine boss" enabled murphy pacific to raise much longer prefabricated girders than existing barge cranes would have allowed. box girder and deck sections were fabricated in murphy pacific's richmond yard and were carried by "marine boss" to the bridge construction site. "marine boss" was sold for scrap in 1988 to weeks marine in new jersey, who renamed it the "weeks 533" and refurbished it. "weeks 533" has since been used for several notable heavy lifts, including moving the concorde and "enterprise" onto the intrepid sea, air &amp; space museum and lifting the downed hull of us airways flight 1549 from the hudson river.
