It has been becoming general that an axial vibration damper is installed on the crankshaft of long-stroke diesel engines in order to minimize the axial excitation forces transferred to the hull through the thrust bearing. But the report that the axial excitation force increased at MCR in spite of the establishment of the damper has been occasionally presented, and besides the fact that peak to peak value (P-P) of the stress fluctuation at crank pin fillet increased in some cases as compared with P-P of the case without the damper has been confirmed as a result of full scale measurement. Therefore, the authors developed the new evaluation system for the vibration and the crank pin fillet stress of the crank shaftings with the axial vibration damper, and introduce the details in this report. In this system, the natural vibration and forced vibration are evaluated by means of a complex eigen value solution. The calculated results of the axial vibration response and crank pin fillet stresses have been compared with the measured ones, and the both show a fairly good agreement respectively.

A numerical simulation method of the motion of a rowing race boat is developed in order to evaluate the performance of oar size and rowing pattern. The driving force of blade is measured experimentally. The resistance of the boat is referred to the experimental result carried out in a towing tank. The motion of crew, which is most important in the simulation, is evaluated from the equation of a boat motion where the other terms are experimentally measured. These measured external forces are modeled by Fourier series or polynominal expressions. The equation of a boat motion is numerically solved by use of Runge-Kutta method. The Simulated boat velocity and force acting on blade are compared with the measured ones. The experiment was carried out in cooperation with the crew at Hiroshima University. Good agreement with the simulated results and measured ones shows that the present simulation method has merit to evaluate the rowing performance. Through the present simulation method, outboard length, blade area, stroke rage and phase of catch are evaluated.

In the strip methods of OSM, NSM and STF, the wave exciting forces are expressed in terms of the added-mass and damping coefficients evaluated at the encounter frequency, ω_e. In the Newman's strip method, however, they are expressed in terms of the coefficients as a function of the incident wave frequency, ω_o, In this paper, it is assumed that the diffraction potential for the vertical exciting forces is periodic in the x-direction (the x axis is positive forward), while the diffraction potential for the horizontal exciting forces is slowly varying in the x-direction. From these assumptions, it is obtained that the vertical exciting forces should be calculated on ω_o and the horizontal exciting forces should be calculated on ω_e. The exciting forces on a model of S-175 container ship in regular oblique waves are measured in IHI Seakeeping and Maneuvering Tank and the test results are compared with the calculations on ω_e and ω_o. The followings are conclusive results ; 1) Test results of heave exciting forces and pitch exciting moments are in good agreement with the calculations on ω_o, and show no effect on the forward-speed. 2) Test results of sway exciting forces and yaw exciting moments show a good agreement with the calculations on ω_e.

It is said that electrification of the auxiliaries on small cargo ship is more useful than that of steam drive. The O.S.K steamer"Ondo Maru"(680 gross tons) had installed a main diesel engine of 600 B.H.P., steam driven auxiliary engines and an oil burning boiler. The fuel consumption was too much and so the next ship of same type"Mihara Maru"had installed the electric driven auxiliaries of d.c. system, and got good result. These valuable experiences tell us that the electrification is more useful than steam drive. The electrification of the auxiliaries had almost adapted the d.c. system, by the reason that the characteristics for winch and windlass are more suitable than a.c. system. Therefore, the a.c. system for auxiliaries of cargo ship has been disregarded. However, it is considered that the a.c. system for the auxiliaries of small cargo ship is worth studing. Now, our company decided to build two small cargo ships of"F"type (about 510 gross tons) and I am planning the electrification of the a.c. 230 volts, 60 cycles, 3 phase, for the auxiliaries. Here we call, temporarily, the ship less than 500 gross tons, as the"small cargo ship". The ship of"F"type is installed a main Diesel engine of 550 B.H.P. and following auxiliares, The generater for the source of these auxiliaries are two sets of 55 k.v.a. which are drived by a Diesel engine respectively. (a) Winches 4 sets of 15 k.w. (b) Windlass 1 sets of 15 k.w. (c) Capstan 1 sets of 2 k.w. (d) Pumps 6 sets of 0.75 to 5 k.w. There are other electric installations as follows : (a) Room heaters. (b) Ordinary illuminating lamps and navigating lamps etc. (c) Wireless telegraphy. (d) Radio direction finder. (e) Echo sounding equipment. The electrification of winch, windlass and capstan by the induction motors of pole change wound rotor type, shall have many points of consideration. In this paper, it is concluded that the electrification of the auxiliaries on small cargo ship by a.c. system is rather suitable for quick building of ship, and cheapness of equipments and easy maintenance of auxiliaries.

This engine is of two-cycle airless-injection type and has been developed by Mitsubishi Zosen Kaisha after about five years of experiments and studies. The first four sets of the engine were adopted by Osaka Shosen Kaisha for their M. Ss. "NANKAI MARU" and "HOKKAI MARU" and the actual service records have now been obtained. This paper deals with some special features of the engine, such as the scavenging, combustion, mechanical efficiency and construction.
