It was originally ordered for bridge construction and has since been used in several notable heavy lifts. ==History== The ''Marine Boss'' floating barge-crane was built for Murphy Pacific Marine. The barge was assembled by Zidell Explorations from scrapped ship steel in Oregon in 1966 and fitted in San Francisco with a heavy 500-ton revolving crane made by Clyde Iron Works to perform the heavy girder and deck-section lifts for construction of the 1967 San Mateo-Hayward Bridge. At the time it was the largest barge crane in the western United States. In the 1970s, ''Marine Boss'' was sold to J. Ray McDermott & Co., who had introduced the first 500-ton floating cranes for offshore platform construction in 1965 and were operating a similar fleet of barge-cranes under the McDermott Derrick Barge (DB) class. McDermott would later sell it for scrap in 1988 to Weeks Marine in New Jersey, who renamed it the ''Weeks 533'' and refurbished it from 1997-2000. ''Weeks 533'' is considered the flagship of the Weeks fleet. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Weeks 533」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
