This unit has the capability of welding 50-foot stiffened plates together to form module panels with a single welding pass.

FRASER Circle 11 on Reader Service Card Fraser Shipyards, Inc., located in the Port of Duluth/Superior at the west end of Lake Superior, recently completed a busy winter. The yard converted the USS Great Lakes Fleet, Inc.'s George A. Sloan to die- sel power. Sea trials were held in June this year. In addition, the ship- yard performed major as well as routine repair and maintenance work on several other Great Lakes vessels. The current backlog of work scheduled for the drydocks includes six vessels for five-year inspection and routine repairs. In addition, Fraser maintains a fleet of work- boats that service vessels in the port on an around-the-clock basis. The decline in tonnage on the Great Lakes as a result of the down- turn in the economically depressed steel industry has adversely affected the yard, which had been a leader in vessel lengthenings and self-unload- er conversions. Fraser management is confident that their efforts to sur- vive the recession in the shipbuild- ing and repair industry have strengthened the yard. They plan to aggressively pursue their market share of conversion and repair work in the future.
