BAY SHIPBUILDING

Circle 10 on Reader Service Card

Bay Shipbuilding Corporation in

Sturgeon Bay, Wise., is a wholly owned subsidiary of The Manitowoc

Company, Inc. Bay was established in 1968 when Manitowoc relocated its shipbuilding and repair opera- tions to Sturgeon Bay. Since that time, an aggressive expansion pro- gram that included renovation, new facilities and equipment, land ac- quisition, and dredging has greatly increased the yard's capabilities, making it one of the most modern shipyards on the Great Lakes.

Drawing workers from a three- county area, Bay is Sturgeon Bay's largest employer. It is a full-service yard with complete in-house capa- bilities to design, engineer, build, repair, convert, repower, retrofit, or jumboize salt-water ships and tug/ barges up to 730 feet in length, and

Great Lakes ships up to 1,100 feet long. Since its founding, Bay has built 34 vessels including 17 self- unloading bulk carriers ranging from 550 to 1,000 feet in length.

The yard's current orderbook in- cludes three 700-FEU container- ships for Sea-Land Corporation that are being built to the most optimis- tic construction schedule attempted in the U.S. since World War II. In addition to new ship construction and vessel repair, non-marine in- dustrial products are ideally suited to Bay's extensive fabricating and machining facilities.

Capital improvements made over the years included a 1,158-foot-long, 140-foot-wide graving dock com- pleted in 1976. This dock can be divided by portable gates to allow the flooding of one end while work continues in the dry end. A 200-ton- capacity gantry crane added in 1978 spans both the graving dock and the adjacent block assembly area that is used to construct individual hull and deck sections.

Bay also has a 7,000-ton floating drydock, 604 feet long and 70 feet wide, used primarily for survey, re- pair, and conversion.

A computerized lofting system has been installed to expedite the process. This system numerically controls both a dual-head plasma arc burning machine, with a 22- by 41-foot water table, and an oxygen fuel burning machine.

A 30,000-square-foot expansion to the existing heavy fabrication shop was completed in 1981. A higher (continued on page 20) 12
