Marine Engineering
Outline Activities
The researches about ship motion in waves and developments of underwater vehicles and robots for ocean observations and exploration of ocean bottom resources have been carried out.
I have lectures of introduction of earth environmental engineering, calculation for ship design, ship design, ship drawings and ocean environmental intelligence in the under graduate school. And ship preliminary design and 3D-CAD for ship design are lectured in the graduate school.
I am a member of the Japan society of naval architects and ocean engineers, the international society of offshore and polar engineers and carrying out lectures for public and students.

1. Nitin D. Thulkar, Satoru Yamaguchi, Hydrodynamic Forces of DP Jack-Up Leg when Operating in Vicinity of Seabed, Journal of Ship Research, J Ship Res 1–12.
Paper Number: SNAME-JSR-03200020, 2021.10, [URL], Leg placement and removal are the two most critical operational modes for dynamically positioned jack-ups when working close to an offshore asset. Any positional deviation may lead to collision and damage to the asset. The industry operates with a weak link between the dynamic positioning (DP) system and the jacking system. Current DP systems operate without any sensors identifying the hydrodynamic force variations on the legs and spudcans, which vary between different leg and spudcan designs. When the spudcan is near to the sea bottom, the hydrodynamic force must be reported to avoid large positional deviations driven by the DP system. This article promotes a mechanism to measure these forces using Computational Fluid Dynamics (CFD) analysis to analyze the jack-up behavior, when the spudcan assembly is operating close to the sea bottom..

3. W Koterayama, S Yamaguchi, T Yokobiki, JH Yoon, H Hase, Space-continuous measurements on ocean current and chemical properties with the intelligent towed vehicle "Flying Fish", IEEE JOURNAL OF OCEANIC ENGINEERING, 10.1109/48.820745, 25, 1, 130-138, 2000.01, A research project to develop observation systems for heat, momentum, and material circulation in the ocean and atmosphere was carried out by the Research Institute for Applied Mechanics, Kyushu University, from 1992 to 1997, A pitch, roll, and depth controllable towed vehicle called "Flying Fish" was developed which houses an acoustic Doppler current profiler, CO2 analyzer, and sensors for measuring temperature, salinity, dissolved oxygen, pH, turbidity, and chlorophyll. The length of the vehicle is 3.84 m, the breadth is 2.26 m, the height is 1.4 m, the weight in air is 1400 kg, and the weight in water is roughly 0 kg.
Flying Fish enables us to obtain space-continuous data of physical and chemical properties efficiently in the upper mixed layer of the ocean. From 1994 to 1997, the vehicle was used for observations in the northern, southern, and central parts of the Japan Sea in a collaborative study by Japan, Korea, and Russia. Examples of data obtained are shown in this paper and the results of current velocities are compared with those taken by other observation systems..
