Up to the present, 17・5 kg/cm^2 G. and 365℃ were the highest pressure and temperature in steam plants of merchant vessels, in this country. The steam condition of 27 kg/cm^2 G. and 390℃ was adopted in these new ships, where coal was the fuel, in order to improve the whole plant efficiency, also save weights and spaces of boilers. The three main boilers are the Mitubisi three drum type marine water tube boilers, having the heating surface of 385 square meters each, equipped with the Taylor multiple-retort underfeed stokers for burning the Fushun coal, the horizontal type convection superheaters and the tubular air preheaters. On the official sea trials of the S.S. "Oryoku-Maru, " the whole plant efficiency of 18.9% was obtained.

The antarctic whaling tanker, "Nisshin Maru" (22, 000 tons deadweight) was successfully built on 28th 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.[table]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 was also paid 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 epochmaking record of speely 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 : [table]

The new Antarctic Observation Ship has certain features such as a semicircular bottom and a large lunching weight considering the hull scantling.To enable the lunching of this vessel to be successfully carried out, the lunching berth was extended some 40 M into the sea and this was accomplished by using 6 flaoting tanks, which operated on steel balls. We summerize here about the enforcement of the plan for this vessel.

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. 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. 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.

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 using 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 problems 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 solve these problems will be protested.

The "Argentina Maru" is the first motor passenger and cargo ship to be constructed under the special Shipbuilding Subsi〓y of the first grade gr〓nted by the Japanese Government, and this magnificent Round-the-Wor1d Liuer is wholly of Japanese construction aud materia1s. In vi〓w of these circumstances, it seems to be appropriate to make some reference to the ship ; therefore a general description of the vast design, construction, equipment, etc., is given in this paper.

Japan's first postwar submarine "Oyashio" was launched at No.1 Building Berth at Kawasaki Dockyard on May 25,1959. Representing the latest fabrication techniques in the construction of all-welded undersea craft, this vessel is now commissioned under the Japanese National Defense Agency.This paper deals with the records of fabricating and welding techniques used for the construction of this craft. Summerized below are the points worthy of special mention : 1) Used for inner hull structure were weldable high tension steels, HT 50 and HT 60,and various quality tests were performed on each of the steel plates used.2) The so-called unit cylinder assembling system was adopted in order to shorten the period of construction.3) The length as well as the fabricating sequence of the unit cylinder assembly were decided in accordance with the results of the fabricating tests on models.4) Many kinds of special jigs were devised in order to maintain the circularity of the inner hull structure and used successfully in the construction.
