In the previous report 1), 2), the authors discussed the stopping abilities of ships equipped with controllable pitch propeller (CPP), from a viewpoint of both sea trial results and theoretical computation about transient phenomena, by using a one-dimensional equation of ship motion. They described the CPP ship's superiorities in both its easy manoeuvring of astern-going and overa11 stopping abilities. As for the results of theoretical calculation it was found that CPP stopping characteristics can be estimated enough quantitative1y. In this report, the authors describe the fluctuating characteristics of shaft revolution number at CPP crash astern test, by solving simultaneous equations in respect to ship motion and prope11er-shaft revolutional motion. Furthermore, using the about computer program, the authors investigated influence of blade changing time on fluctuation of shaft revolution, CPP blade root strain, etc. It is also very important to investigate on stopping abilities of FPP ships in order to grasp stopping abilities of CPP ships. The authors devide transient phenomena of FPP ships into five ranges and fully examine each of them from actual astern test results. Based on these results, they calculated some transient phenomena of FPP ships with computer program and compare them with actual trial data and make some simulation to find important factors of stopping abilities of FPP ships. Finally they make comparisons of stopping abilities under the same initial condition, between CPP-installed and FPP-installed ships by astern programs for them.

This report mainly describes the 4-quadrant characteristics of the controllable pitch propeller. Using three kinds of models of controllable pitch propellers for high speed container ship, high speed reefer and large ore carrier, we have carried out the 4-quadrant open test at Kawasaki's circulating water channel. From polynominal regression analysis using 0.7R pitch ratio, these open characteristics can be expressed with sufficient accuracy as follows: K_t, K_q = Σ__iΣ__kC_<ik>P^iJ^k Only by this regression formula, the open characteristics can be expressed irrespective of various original pitch and area ratios. In regard to stopping ability, we have solved equations of ship motion by using the characteristics obtained from the above formula and made simulation analysis, and studied effect of C.P.P. pitch angle speed, effect of F.P.P. revolution changing time, and effect of C.P.P. pitch changing pattern for the case of Ship No.1120.

Recently KHI built three kinds of ships equipped with controllable pitch propeller (CPP). They are a reefer, a container and an ore/oil tanker and all of them are higher-powered ships in comparison with those built before. As speed and size of ships increase, necessity of better stopping abilities has been increased. Investigations on the stopping abilities of ships with fixed pitch propeller (EPP) have been reported in detail by many researchers, but those on CPP ships are very rare. As the first step of the investigation on the stopping abilities of ships equipped with CPP, the authors report on crash astern test results, measured at sea trial test of above mentioned ships and compare with those of FPP ships. Furthermore they show the results of computation about transient phenomena in case of CPP ships by using one dimensional equation of motion and compare them with sea trial results.

The "Argentina Maru" is the second ship built in Japan after the last World War which is originally designed as an emigrant ship. Her length and depth are same as the first ship "Brasil Maru", but many improvements have been made on various items. This paper takes up the most outstanding points out of them, such as, to pay more attention to stability, to adopt the sprinkler system for fire protection, and to adopt constant running system for water supply, etc.

Two liberty ships, the "EVILIZ" and the "EVICYNTHIA", were elongated and reconstructed at the Innoshima Shipyard of Hitachi Shipbuilding and Engineering Co. Ltd.. Seizing this opportunity the authors measured the distribution of the locked-in-stresses along the cutted cross section of the vessels. This paper contains the results of measurement and brief consideration on them.

This heavy derrick gear was installed in sister ships SHUNKOKU-MARU and SHUN-EI-MARU, completed in Kawasaki Dockyard Company in July and August, 1960, respectively. Both ships which are owned by Nihon Kisen K.K. and operated by Hinode Kisen K.K., having identical overall length of 132.480m and deadweight of 9,009t, were designed to load and carry extra-super-heavy cargoes, such as rolling stocks, barges, heavy machineries and etc. The most unique feature of the heavy derrick, which has the capacity of 180 tons, is the adoption of the so-called "2 hatch-1 derrick system", enabling one unit of heavy derrick to serve two cargo hatches. Adoption of this system realized decrease in weight of about 20% from the ordinary "1 hatch-1 derrick system". The gear consists of a tower mast installed on the ship center line of maximum diameter 3.600m, with a goose neck ring provided at its foot and with a 180 ton heavy derrick boom connected with the ring. Fall wire and topping lift wire, which are led inside of the tower mast, are wound by 35 ton steam driven heavy duty winches installed on both sides of the upper deck. A heavy derrick boom is capable of rotating about 320° from 70° swing out position at the forward starboard side to 70° swing out position at aft starboard side. In order to minimize the friction by rotation Of the goose neck ring, the ring is supported by 692 roller bearings. The results of 200 ton overload test carried out for the gear illustrated favorable agreement with the respective design values. Details, design and the test results of the gear are described below.

In the annexing table the relation is shown between P.S. and machinery weight investigated on 39 diesel driven vessels classified into three types, i.e., cargo vessels with electric deck auxiliaries, cargo vessels with steam deck auxiliaries and tankers. In each type of vessel, machinery weight is itemized into eight main sections: main engine, shaft & propeller, auxiliary machinery, boiler, funnel & uptake, piping, sundries and dynamo. Relation between weight percentage of each section and p.s. is indicated on graph. It is hoped that this investigation will be useful for basic design and cost estimation of vessel.

In vibration design of resonant avoidance to fore and aft vibration of superstructure, it is an important technology to estimate accurate natural frequency and to avoid it from resonant zone of blade or cylinder frequency in case of resonance. In this second report, authors investigated coupled vibration effect of local vibrating body such as funnel or dodger upon natural frequency of superstructure. By connecting funnel casing and deck of superstructure, natural frequency of superstructure becomes extremely high when its fundamental frequency exists higher than that of funnel. It is shown that this phenomenon can be applicable to avoid resonance in actual ship design of superstructure vibration. Long wings(dodgers)which exist at navigation bridge deck also affect the natural frequency of superstructure. Coupled vibration effect of dodger is found to lower natural frequency of superstructure.
