On the use of the stochastic matched filter for ship wake detection in SAR images
AuthorsFabien Chaillan ; Philippe Courmontagne
Date published2006
AbstractDetecting straight patterns like ship wakes on a SAR image is not easy because there is not a priori information on orientation and position moreover SAR images are Speckle noised. This article proposes to describe a ship wake detection technique based on the discrete Radon transform and the stochastic matched filtering (SMF) used in detection. The association of these two processes leads to a detection algorithm that only requires the knowledge of the second order statistics of the signal to detect and the noise. Experimentation on real SAR images show the efficiency of the technique.

Online Response Test on Saturated Sand Seabed Underneath Structure Subjected to Ice and Seismic Loads
AuthorsM Hyodo ; T Fujii ; K Fukuda et al.
Date published2000
AbstractIn order to investigate the interaction between offshore structure and base ground subjected to seismic and ice loads a substructure on-line dynamic testing system was developed. A dynamic response analysis by computer and a pseudo-dynamic loading test which obtains the restoring force of material experimentally are combined by a computer on-line data processing system. The analyses were carried out on an offshore gravity structure based on sand seabed subjected to ice load and earthquake motion by this method. Unique response behaviour of base ground and structure was observed in this study.

AuthorsFuminori Tomosawa ; Shigeo Tsujikawa ; Tadashi Ono et al.
Date published2004
AbstractThis study aims to investigate the applicability of new materials to marine structures focusing on their durability. To this end a 5-year exposure test has been conducted from 1999 on 3 types of specimens (for corrosion observation tension testing and joint strength testing) made of 21 selected materials (6 nonferrous metals 8 steels 4 composite materials and 3 rope materials). The specimens are exposed at 3 sites: Okinotori-shima and Miyako-jima corrosive environments with high temperature and humidity and a thermo-hygrostatic room in a laboratory. This paper primarily reports on the results of appearance observation of specimens at Okinotori-shima and Miyako-jima carried out in 2002 as well as the findings from observation and experiments on specimens exposed for 3 years at Miyako-jima.

Study on direct hull cooling for next general shipboard thermal management
AuthorsPurwono F Sutopo ; Katsuya Fukuda ; Qiusheng Liu
Date published2008
AbstractOne of the important areas in ship development for the next generation of ships is thermal management. Good thermal management from large heat sources together with reliable cooling technology is the key to energy savings cost efficiency and upgrading a vessel's performance. In this study a conceptual design for thermal management configuration is introduced which will fulfil thermal handling requirements from various heat loads on board ship. The configuration adapts environments for the next generation shipboard cooling application on naval and marine vessels and proposes a model for the direct ship's hull cooling method using flat plate heat sink and water cooling as part of an integrated thermal loop system called TPCLT (two-phase closed-loop thermosyphon). The configuration trade-offs the applicable thermal handling methods for each kind specific purpose of equipments or devices and heat load network to gain the appropriate one. On this basis preliminary design study on the required configuration of the TPCLT with direct hull cooling method is described.

Three critical factors and their influence on the spread of microbiological waterborne diseases in sub-Saharan countries (with special emphasis on cholera)
AuthorsN L Musekene ; M Mepfumbada ; P Kempster et al.
Date published2006
AbstractIn recent years the magnitude of microbiological epidemic outbreaks has reached alarming proportions. Those hardest hit are from sub-Saharan countries. Outbreaks of acute intestinal bacterial infection caused by the bacterium Vibrio cholerae have claimed a greater percentage of lives in sub-Saharan countries than the rest of the world combined particularly amongst women and children. There are critical factors that exacerbate the spread of cholera amongst these populations. Poverty the lack of a proper water supply and sanitation the basic hygiene practice and absence of health systems need to be addressed in order to catalyze solutions to the growing problem. This paper focuses mainly on reviewing the status of cholera and the identification of homogenous attributes within the sub-Saharan African countries which are influencing the spread of such diseases. A containment programme is proposed to enable sustainable development to take place in the region.

Wave-current loading on a shallow water caisson
AuthorsD L Kriebel ; E P Berek ; S K Chakrabarti et al.
Date published1996
AbstractThe results of laboratory model tests were used to assess the accuracy of the API RP 2A method of predicting wave-current loading on a shallow water production caisson in extreme random waves. Model tests were conducted with a 1:20-scale model of a 36-inch diameter caisson in 50 feet of water. Tests were conducted in extreme (breaking) random waves both with and without in-line currents. Based on analysis of 138 extreme waves it was found that predicted in-line fluid velocities were 6% larger than measured values on average while predicted in-line wave forces and moments were 10% and 15% larger than measured values on average. Unfortunately not all predictions were overly conservative. Several large breaking waves produced measured forces and moments 1.5 - 2.2 times larger than predicted. For these and other breaking waves measured wave loads were strongly affected by dynamic amplification effects caused by ringing of the structure after wave impact.

A study on human factors in engine room
AuthorsH Shiihara ; N Sumi
Date published2000
AbstractA study is presented which is carried out to determine the characteristics of human error that are supposed to happen daily in an engine room. The results show that the majority of machinery failure on ships less than about 10 years old is attributable to human error. However constructive defects have greater impact than human factors on major failure in ships over about 10 years old. Future research is proposed to find out which characteristics of human error has the greatest impact on breaking the chain of mistakes caused by human factors when constructive defects also exists.

An experimental investigation of wave loads on a mat-like floating structure in waves with short length
AuthorsS Yamashita ; A Ito ; T Kabaya
PublisherAmerican Society of Mechanical Engineers - ASME
AbstractResults of a systematic series of wave-excitation tests to investigate the wave-induced loads on a very large floating structure are reported. The model consists of five identical module models; wave induced forces on each module were measured in regular and irregular waves with varying the incident angle of waves. Hydrodynamic pressure on the hull surface were also measured to examine the characteristic features of pressure distributions.

An Overview of Ice Loads on Slender Structures
AuthorsM E Johnston ; G W Timco ; R Frederking
Date published1999
AbstractThis paper presents in a concise and unified format the loads that have been measured on slender structures. Nine different structures have been examined and general information on the loads are presented. The data on slender structures indicate a maximum load of 2500 kN and show a reasonable correlation between the measured load and ice thickness. This correlation is encouraging since the data was collected from a wide range of structures that were in different types of ice regimes. In total it illustrates the load levels and general trends of load with increasing ice thickness for slender structures placed in ice covered waters.

Analysis of drift force on VLFS by the near-field approach
AuthorsTomoaki Utsunomiya ; Eiichi Watanabe ; Naoyuki Nakamura
Date published2001
AbstractAnalysis of wave drift forces for a Very Large Floating Structure (VLFS) is presented. The drift force can be calculated either by the far-field method or by the near-field method. This paper focuses on the near-field method by which the drift force acting on the floating body alone can be calculated even when it is accompanied by breakwaters. Numerical examples for drift force on a VLFS close to a breakwater are presented where the effect of the breakwater is found to be remarkable.

AuthorsJean T Ellis ; Douglas J Sherman ; Bernard O Bauer et al.
Date published2002
AbstractAn attempt is made to assess the impacts of brush bundles on boat wake energy and to determine if the degree of effectiveness depends on water depth. Field work was conducted on Georgiana Slough in August 2000. This study found that brush bundles are an effective method to reduce potential boat-wake induced levee erosion. After some background information the experimental design is looked at. Next results are discussed.
