Bay Shipbuilding Progressing With Construction Of Sea-Land Containerships

Bay Shipbuilding Corporation of Sturgeon Bay, Wise., recently attained three major milestones in the construction of three D-7 containerships being built for Sea-Land Service.

Hull 735, the first of the 710- foot vessels in the series, was floated out of Bay's 1,158-foot graving dock and berthed at one of the yard's outfitting piers. On the same day, the after end of Hull 736, including the machinery space, was floated forward to its completion position in the dock. Each ship will be powered by a low-speed Mitsui/B&W 7L70MC diesel rated at 22,000 bhp.

The third event took place just three days later, when the keel was laid for Hull 737 in the after end of the graving dock. Erection began immediately on the after end of Hull 737, the final vessel in the three-ship series.

When Hull 736 is ready to be floated out of the dock and moved to an outfitting pier, three large intermediate gate sections will be installed to isolate Hull 737 from the flooding waters of Sturgeon Bay.

After pump-out of the dock, the three gate sections will be removed and erection of Hull 737 will be completed in its present location.

This float-out/float-forward procedure allows Bay maximum utilization of its graving dock, making it an efficient tool in ship construction and repair.

Bay Shipbuilding, a subsidiary of The Manitowoc Company, is one of the largest and most modern shipyards on America's "North Coast," the Great Lakes.

The Wisconsin shipyard contin- ues to pursue both new construction and vessel repair projects. Presently under contract, in addition to the three Sea-Land containerships, are two 6,000-cubic-yard, hydro-dump barges for Great Lakes Dredge & Dock Company.
