Influence by Shear Wave of Ice with Sea-surface to Sound Propagation Characteristics in Arctic Ocean using Elastic Parabolic Equation Method
Shear Wave of Ice Sound Propagation Characteristics Elastic Parabolic Equation Method
2009/8/19
Characteristics of pulse propagation in Arctic Ocean were calculated by elastic Parabolic Equation (PE) method based on rotated Pade approximation. It was assumed that the transmitter was placed at 10...
On the Influence of Loading Condition on Characteristics of Hydrodynamic Forces in Steering Motion—Study with a Component-Type Mathematical Model—
Hydrodynamic Forces Acting on a Hull Component-type Mathematical Model Loading Condition Coefficient of Hydrodynamic Characteristics
2009/5/12
The authors have developed a component-type mathematical model of hydrodynamic forces acting on a ship hull in steering motion that is deduced from the simplified vortex model. This mathematical model...
On Influence of Propeller Geometry on Underwater Noise of Propellers
Propeller Underwater Noise Cavitation Highly Skewed Propeller Propeller Design
2009/5/12
Low-level noise propellers with a higher propulsion performance are required lower incipient cavitation number of tip vortex cavitation and even if tip vortex cavitation is developed, to depress the u...
Influence of Surface Properties of Coatings to Frictional Resistance
Frictional Drag Reduction Self-Polishing Paint Water-Repellent Paint Sand Roughness Scale Effect
2009/5/12
In order to clarify correlation between properties of coating on ship hull surfaces and frictional resistance, experimental studies were carried out. A rotating cylinder type dynamometer was newly dev...
Influence of Outrigger Position on the Performaces of a High Speed Trimaran(1st Report: Resistance and Wave Wash)
Outrigger Position High Speed Trimaran
2009/4/30
Influence of outrigger position of a high speed trimaran on the resistance and wave wash was investigated by the tank tests changing 9 outrigger positions of the trimaran model. The trimaran is compos...

Outrigger Position High Speed Trimaran
2009/4/29
Influence of outrigger position of a high speed trimaran on the maneuverability was investigated. The trimaran is composed of the center hull with L/B = 8.0 and B/T = 3.57 where L, B and T denote the...
Influence of Outrigger Position on the Performaces of a High Speed Trimaran
Outrigger Position High Speed Trimaran Wave-Induced
2009/4/29
Influence of outrigger position of a high speed trimaran on the wave-induced motion was investigated. The trimaran is composed of the center hull with L/B = 8.0 and B/T = 3.57 where L, B and T denote...
Development of a Weather Adaptive Navigation System- Influence of Weather Forecast
Weather Adaptive Navigation System Weather Forecast simulations
2009/4/29
We propose a new navigation system to decrease fuel oil consumption and CO2 emission from ship. To decrease them it is important to avoid rough seas and to reduce the speed of ship. Therefore the syst...

In the previous paper, influence of applied stress, residual stress and toughness of welded joint on brittle crack propagation was analyzed based on a fracture mechanics model developed by the authors...
Influence of the Body Shape and the Trapped-air on the water impact problem
Trapped-air Body Shape
2009/3/30
In this paper, the influence of the body surface and trapped air on the water impact problem is discussed. It is assumed that the water surface can be expressed by a subsequence of circular hollows, a...
