404 Transferring a Brick Building by Water In the October Marine ReEvIEwW men- tion was made of the transfer of a brick building from the plant of the Manitowoc Boiler Works to the yard of the Manitowoc Ship Building & Dry Dock Co., Manitowoc, Wis., in one of the sections of a floating dry dock. The problem was an interest- ing one because obviously in trans- ferring the structure from the wharf to the floating dock means would have to be resorted to to overcome the submergence of the dock, and thus any strain upon the building it- self: How this was accomplished is told. in the following from the ship Ee ous SAT aaa THE MARINE REVIEW made so that the floating dock would remain at a constant draft during the transfer. This was effected by mak- ing two heavy plate and angle brack- ets which could be bolted to the end of the floating section, utilizing the bolt holes ordinarily used in connect- ing the sections. These brackets were _five feet vertically and three feet hori- zontally, and when bolted in position overhung the edge of the wharf. The level of the dock floor was then lowered by the admission of water ballast, the brackets having been ad- justed to rest on the edge of the wharf, the pressure being judged by the crushing of soft pine pieces placed under them. The amount of water ballast was calculated as sufficient on being pumped out to raise the brack- ets from the wharf after the weight of the building was fully taken on the NS o 2 ne -- = am SKETCH SHOWING HOW THE BRICK: BUILDING WAS PLACED ABOARD . THE FLOATING DOCK building company: "Timbers were placed under the brick building and it was moved from its foundation to near the edge of the dock in the usual way. A single sec- tion of the new floating dry dock which was to be used in transporting the building was then disconnected and towed from the yard to the Boiler Works dock, a distance of one-half a mile. The problem was to transfer the brick building, weighing approx- imately 170 tons, from the solid wharf to the comparatively uncertain and yielding support of the floating dock section without straining the structure and thereby seriously damaging the building. It will be evident that at some period of the transfer the brick building would be partly supported on the dock and partly on the floating 'pontoon, and arrangements had to be dock. As the weight of the building was gradually transferred from wharf to pontoon the water ballast was pumped out, care being taken to keep a moderate pressure under the brack- ets all the time. When the building was fully carried on the floating dock the balance of the water was pumped out, the brackets freeing themselves from the wharf and the section was ready for towing to the new site for the building. In unloading the same plan was adopted and the building was landed on its new foundation without any evident sign of stress." The Manitowoc Ship Building & Dry Dock Co., is now. making: an .ad- dition to the brick building which when completed will contain the com- bined forces of the boiler shop and shipyard. The company is consoli- dating both plants in the one yard. November, 1913 i Items of General Interest There are at present building on the Clyde five vessels to be driven by Diesel engines.

The Standard Oil Co., New Jersey, has given contract to the Newport News Ship Building & Dry Dock Co. for an oil tanker 460 ft. long by 60 ft. beam and 29 ft. deep. The Alaska Pacific Steamship Co., through its president, H. F. Alexan- der, has purchased the steamers Ad- miral Schley and Admiral Dewey from the United Fruit Co. Andrew Scott, of London, secretary of Lloyds Register of Shipping, and James French, formerly surveyor for the United States and now principal surveyor at Glasgow, are making a tour of American shipyards. In order to provide suitably for the tourist traffic during the coming sea- son on the canal zone, the Panama railroad has decided to add a trip through Gatun lake as one of the reg- ular features of its sight-seeing serv- ice. Gatun lake covers 164 square miles. We do not realize the wonders of electrical transmission until it is brought home to us by some striking fact. At one minute after 2 o'clock on the af- ternoon of Oct. 10. President Wilson touched an electric button to blow up the Gamboa dyke. At two minutes after 2 a message was received in New York that the dynamite explosions had taken place: The wonders of wireless are exemp- lified in little things as well as in big ones.
