Marine Review FOUNDED 1878 SHIP OPERATION : Volume 64 Need New Ship Model Tank, Advance in Ship Design T THE recent meeting of the Society of A Naval Architects and Marine Engineers in New York, the president of the so- ciety strongly urged the authorization of funds to proceed at once with the construction of a new national ship model tank. If we are to keep pace with other maritime countries in the scientific development of ship design such a tank is a necessity. Itis of great importance to the merchant marine and to the navy. It will directly apply to both ocean going vessels and those on inland waterways. It is a national project, including aviation as well as all ship- ping. It would be largely self-liquidating since tests for private companies and individu- als are done at cost. As the president of the society pointed out, the navy department has selected a site and has completed plans and specifications for the new tank. Everything is ready to proceed as soon as the funds have been allotted. Importance of Research and Experiment The forward looking vessel owner realizes the vital importance, not only, of the skillful practical application of the most advanced ex- isting technical information to the design and construction of ships, but also that study, re- search and experiment should be encouraged in order to achieve still better results. This proj- ect, therefore, which is now before Harold L. Ickes, as public works administrator, should receive the support of every shipowner by go- ing on record in its favor. Of special significance also was the sugges- tion of the president of the society that a re- search be made on a large scale, into the eco- nomies of shipping. Due to the number of MARINE REVIEW SHIPBUILDING . December, 1934 CARGO HANDLING Number 12 problems involved and their complexity this re- search should be conducted by a governmental agency or by endowment of a research body at one of the larger universities. The vast range of the development of naval architecture and marine engineering in the past 124 years and the genius of one of its pio- neers are vividly brought to mind in the paper, presented at the meeting, reproducing many of Robert Fulton’s original drawings. That it may well be worth while to consider, on the basis of original design, the justification of what has come to be more or less, stereotyped standard practice in ship structural design is the interesting theme of another paper. Practical Design Is Advanced Again the valuable work of the United States experimental model basin is emphasized by papers on propeller design and measurement of propeller thrust on shipboard. Knowledge of both of these important factors in ship de- Sign is thus advanced. Is ground tackle, fol- lowing established routine practice, heavier than need be, is the question asked and partly answered in the affirmative, in another valuable contribution by the navy to ship design. Ventilation of ships including the currently important subject of air conditioning; arc weld- ed ship construction; marine and naval boilers, their design and application; bunker fuel oil problems; and safety in the design of small tankers, are some of the additional subjects covered in papers presented at the meeting and referred to in more detail beginning on page 11. These papers cover a wide range of technical information of value in the improvement of the design and operation of ships. In the United States navy there are no battle cruisers. The value of this type of vessel as demonstrated in action brings the author of the paper on the battle cruiser to the conclusion, ‘Large navies of the near future will be at a disadvantage without vessels of this type.”’ December, 1934 7
