It is well known that a submarine has the excellent propulsive performance in high speed. navigation in deeply submerged condition, but few papers have sufficiently shown economical feasibility of submarines for commercial use.The authors have studied about the feasibility of submarine tankers with a view to develop technical problems of commercial submarines. At first, the experiments on five submarine tanker models with the circular and rectangular hull sections were performed by method of three-component measurements at Mejiro No. 2 Tank.Examining the resistance, stability, floating draft and general arrangement of the submarine tankers, the authors chose the ST-2 type rectangular hull form as best for the submrine tanker. The lines of the ST-2 type hull form was shown in Fig. 3The ST-2 type submarine tankers with various dead weights and shaft horse powers were designed and their investment, operation cost, annual profit, freight rate per dead weight and capital recovery factor were calculated. The results of this study were summarized in Fig. 19 to 23. The best submarine tanker in the point of view of commercial feasibility was 40, 000 tons in dead weight and 20, 000 horse powers in shaft horse power under restrained condition within 14 meters in maximum floating draft. On the contrary to the previous opinions, was shown the fact that the submarine tankers would not be very fast than present conventional tankers. As shown in Fig. 23, the submarine tanker would not have commercial feasibility without drastically decreased cost of nuclear power plants.

The completion of the M. S. Tatsuta Maru, the sister ship of the Asama Maru and the biggest motor liner of almost wholly a Japanese production, is an important event for Japanese Shipping and Shipbuilding. On this remarkable occasion, it does not appear to be wholly nonsense to make some reference about these ships.<br>In this paper, a short review is made about the vast designs and long efforts to arrive at the final elaborate design of the Pacific Liners.<br>Some results are also picked up from those of the exhaustive trials, and finally, an attempt is made to lay out 2, 000 B. H. P. geared Diesel installation for a high speed Trans Pacific Liner which might come into question in future.

The first part of the paper deals with the combination comprising a triple expansion engine, with poppet valves for high and intermediate pressure cylinders, and direct coupled to the main shaft line, and an exhaust steam turbine, to utilize the energy contained in the exhaust steam from the engine, double reduction geared to the main shaft line. In this system, the turbine is to work for ahead direction only; an automatic friction clutch is to disengage the turbine when the main engine is to run in astern direction.Mechanical regilient coupling composed of friction disks and a number of coil springs is contained inside the first reduction gear wheel, and is arranged to take off uneven torsional shocks taking place due to the action of the crank shaft of the reciprocating engine.In the second part, description is given about the combination consisting of a set of double compound high speed engine, single reduction geared to the main shaft line, and a low pressure turbine, double reduction geared to the same line. In this case an astern turbine is also arranged. The exhaust steam from the engine is controlled with special manoeuvering valve to enter into either ahead or astern turbine as desired and the valve is to cooperate with the reversing mechanism of the reciprocating engine.Particulars of the ships having these systems of combination machinery are given in the attached table also the performance data of their maiden voyages are given in another table.A sketch of the design of the machinery space of twin screw engines and its brief description is given in the last part of the paper.

It has elapsed many years since the water tube boilers were introduced into marine use, with full success in European countries and in America. In Japan, on the contrary, this type of boiler has been used for some large cargo ships before the war and for a few kinds of War-time Standard Type of Ship under instruction of the former Japanese Navy during the war, but now no positive demands.It is generally recognized that through the possibility of high pressure and high temperature steam usiug the water tube boiler, the higher thermal efficiency and weight reduction in total engine part are gotten. This fact mokes us profitable to adopt the boiler in this country where fuel and steel are excessibly short. Nevertheless, there are hesitations in our ship world to adopt this type for marine boiler due to li anxiety of reliability and difficulty of handling.The prob ems on reliability and difficulty in handling. are as follows;(1) Danger of low water, (2) Trouble through feed water, (3) Easiness of coal burning.In this paper, the above problems should be investigated to clarify the reality, and if possible new design on the water tube boiler and finally the remedy to so ve these problems will be protested.

The antarctic whaling tanker, “Nisshin Maru” (22, 000 tons deadweight) was successfully built on 28 th Sept. '36 by the Kawasaki Dockyard Co., Ltd., Kobe, in the record of only 216 days from laying down of the keel to the delivery to Messrs. Taiyohogei Kabushiki Kaisha.The vessel is the largest tanker of its kind ever built in Japan, and the following dates indicate the extraordinary speedy program at which she was built in such a short period.The contract signed 28 th, November, 1935.The keel laid 26 th, February, 1936.The launching 1 st, August, 1936.The official trials 14 th, September, 1936.The Delivery 28 th, September, 1936.There were many difficulties which they had to overcome, such as : difficult construction on an ordinary building slip not well arranged with up-to-date crane equipments, unusual short time limit of construction, and hardship of prompt collection of materials, etc.They laid down therefore a strict schedule so as not to delay the delivery and by good luck, it was faithfully obeyed by the men of all departments of the Dockyard Co.Combined with the mutual co-operation of all men and proper supply of all necessary materials, the schedule was very satisfactorily carried out in good order.On the other hand, special attention wa so pa to the working hours as well as labour shifts so that the workmen should not be overworked either mentally or physically.Thus their earnest efforts have at last produced good results with such an epoch-making record of speedy ship building which has never been experienced in the world.In addition, this vessel adopted the “Isherwood Bracketless system, ” the simplicity of which has proved a good effect upon such a quick work as “Nisshin Maru.” The principal dimensions are as follows : Length over all…550'-0''Length between perpendiculars…535'-0''Breadth moulded…74'-0''Depth moulded to upper deck…48'-9''Load draught…34'-25/16''Gross tonnage…16, 764 tonsDeadweight…22, 000 tonsMaximum speed…14'5 knots

The present research has been conducted on the corrosion of the marine engines of about forty sunken ships by means of the field investigation or the deta offered according to the following items:(a) The relation between the corrosion and the period of the submergence of the materials.(b) Is there any difference in corrosion due to the kind of the engines(c) Is there any difference in corrosion between the ships of war-time standardized types and the ordinary ships? (d)Possibility or Impossibility of the reuse of the refloated engines.(e) The process of the repairs of the refloated engines.(f) The condition of the operation of the reused engine.The results obtained are as follows:(a) The corrosion makes progress rapidly at the outset. but after a few years corrosion makes progress gradually.(b) The extent of corrosion of the reciprocating engine is almost similar to that of the diesel engine. In the case of the steam turbine and the mechanical reduction gear, the extent of corrosion is comparatively slight. The boiler may be reused only by replacing the corroded smoke tubes with new ones.(c) The extent of corrosion in the ships of war-time standardized type is generally very remarable compared with the ordinary ships.(d) Corrosion generates on both the small-sized and larger-sized materials, but. as the extent of corrosion is more remarkable in the case of the smaller sized materials. the reuse of the smaller sized materials is almost impossible, while the reuse of the latter is possible(e) The process of the repairs is as follows: After the corroded parts of the engine are boiled in the soda solution, the corroded face of the friction parts are filed off. The other sound parts of the engine may be used without any treatment.(f) The operating condition of the reused engine is pretty good on the whole. The present research has been continued by the Maritime Institute since the writer's initial field investigation conducted in April, 1946, at Mitsubishi Dock Yard in Nagasaki on the corrosion of the main engine of the Kongo-maru, the refloated steamer of National Railway Corporation, receiving grants in aid from the Ministry of Transportation. the former owner of the above mentioned Institute and from the Ministry of Education, the present owner of the Institute.It would be a happy thing. if the present thesis could furnish even a little contribution to the refloating of the sunken ships in the future.

試験は, プロペラの回転方向として, 内回りと外回りの2つについて実施し比較した。試験結果をまとめると次の通りである。1. 内回りプロペラにおいては, 船尾が岸壁から離れ難く, 横移動が不能となる場合もある。外回りプロペラにおいては, 横力が明らかに大きいようであり, 船尾が岸壁から離れ易い。横移動が不能となることはない。2. プロペラ回転数の組み合わせをDS/S, S/Hと変化させても, 内回りプロペラ装備船の離岸性能の改善効果はほとんど見られない。同様に, 右舷舵角を0, ±35degと3種類変更させても, 離岸性能改善に大きな効果はない。3. 船の初期位置を岸壁からは離れたところに持ってくると, 横移動は容易となる。Fig.4に横移動試験結果の1例を示す。船影は10sec毎の右から左に動く模型船の位置を表している。内回りプロペラ (Inward) においては船がほとんど横に移動していないこと, 外回りプロペラ (Outward) においては所期の通り船尾が岸壁から離れた後で横方向へ移動していることが分かる。

In oil-tankers of Japan, it is very rare to have steam plants. “Kuroshio-Maru” which was recently completed has three main boilers of such a modern forced-circulating type as never been found formerly in our country. The steam condition of these boilers is 21 kg/cm2 G and 350°C. Each boiler generates steam 17, 000 kg/h at normal and 22, 000 kg/h at maximum. They are of the Kawasaki La-Mont marine water tube type and each has heating surface of 333 square metres excluding air-preheater, and is equipped with five oil burners, La-Mont water wall, superheater, economizer and tubular air-preheater. These boilers were adopted for the purpose to save space and to improve the.whole plant efficiency. One of these boilers was tested on land and obtained the efficiency of 87.29%.

The “Shinshu Maru” is the first ship equipped with Vulcan geared Diesel engines in Japan, and the propelling machinery consists, in brief, of two sets of Mitsubishi single acting, four-stroke-cycle, airless-injection, reversible Diesel engines of special design and two Vulcan hydraulic couplings with reduction gearing. These engines develop a total normal output of 2, 700 B. H. P. at 420 r. p. m., and this speed is reduced to 90 r. p. m. at the propeller shaft.The trials were carried out at one fifth loaded condition, and the results were quite satisfactory as follows : a) The maximum speed of 16302 knots was recorded with two engines at 100 r. p. m. on the propeller shaft, and 12.246 knots with one engine at 72 r. p. m.b) The minimum speed of 3.69 knots was recorded with one engine at 25 r. p. m. on the propeller shaft.c) Entirely uniform torque in the propeller shaft was recorded by the torsion recording apparatus.d) Easy manoeuvering.e) Reliability of running, etc.
