On the prediction of hydrodynamic forces acting on a ship moving at constant drift
AuthorsN Sulficker Ali ; G Dhinesh ; K Murali et al.
Date published2005
AbstractEffects of incidence angle are important for all types of structures and vehicles including those for land sea air and space. Force and moment data for various angles of incidence play an important role in design. The effect of drift angle on a ship is investigated through towing tank tests and using CFD (computational fluid dynamics). Resistance and wave elevations obtained from the computational study are validated with experimental results. Detailed free surface mean velocity and pressure flow fields on the hull surface are obtained from the computational study for Fn ranging from 0.16 to 0.22 and for drift angle ß =0 5 and 100. The lateral force yaw moment and asymmetric flow characteristics are brought out in the computational study.

Shelf Location213c
AbstractAlthough a lot of research has been carried out on the hardware of the pc-based ERS (engine room simulator) there is little research on the educational method using them. The first phase involved carrying out education and training by the discovery learning and the instruction learning and investigated learning outcomes. The results are described from considering the following matters: relation between the learning method and learning outcomes; the type of the error that students tend to commit; influence of the application order of the learning method; an instructor's role in the individual learning; improving points for increasing learning outcomes.

AuthorsV I Yushin
Date published2000
AbstractThe features of functional dependences of wings' aerodynamic characteristics on their motion parameters and orientation relative to the ground surface are considered. The basic methods for obtaining a WIG craft's aerodynamic characteristics are experimental and calculation methods which require the results to be represented as a finite number of loads and moments for specified parameters of orientation and motion of the craft relative to the ground surface. The analytical representation of the airfoil outline and the influence of the outline form on the aerodynamics of wings moving near the ground are discussed.

The International Committee on Seafarers' Welfare: ILO convention 163 and recommendation 173
AuthorsR Rodriguez-Martos Dauer
Date published2005
AbstractWelfare facilities are sometimes still seen by some as something generous and philanthropic rather than as a necessary condition for maintaining a healthy efficient and safe crew. ILO convention 163 and recommendation 173 were adopted in 1987 as a response to the needs of welfare facilities on board vessels and in port. All those countries that ratified it assume responsibility for taking care of the welfare of any seafarers on board any vessel in their ports on board their own national ships. The development of this convention and recommendation are described in regard to the International Committee on Seafarers' Welfare created as an international umbrella organisation dedicated to the practical implementation of the International Labour Organisation instruments on Seafarers' Welfare.

An investigation of ballast water management methods with particular emphasis on the risks of the sequential method
AuthorsLefteris Karaminas
Date published2006
AbstractShips that carry large quantities of a particular cargo are invariably forced to spend time at sea without any such cargo. To achieve a seaworthy condition in terms of stability trim and strength seawater is taken on board to form the ballast condition. The IMO (International Maritime Organisation) has estimated that every year the world's fleet moves ten billion tonnes of ballast water around the world and that on average more than 3000 species of plants and animals are being transported daily around the world. Once these are introduced to local environment it is virtually impossible to get rid of them. This could have a permanent effect on the environment which could have a catastrophic effect on local fisheries. It is therefore imperative that the introduction of harmful aquatic organisms is prevented. LR (Lloyds Register) carried out an investigation on the various ballast water management methods with particular emphasis on the risks of the sequential method. Prompted by the fact that issues pertinent to the sequential method have not yet been fully appreciated by the industry LR began a two-part study using 26 existing ships of various types configurations and sizes.

Chord Stress Effects on Ultimate Strength of DT Tubular Joints
AuthorsD A Pecknold ; C C Ha ; W C Mohr
Date published1998
AbstractA new parametric strength prediction equation for compression DT joints subjected to chord stress is developed based on existing screened test data and on a new FE database that covers a wide range of joint geometries and significantly extends the information available on the effect of chord stress on static strength of compression DTs. This new strength prediction equation appears to provide a better fit to the data than either the current API RP2A (20th Edition) or IS0 proposed draft design guidance.

Effect of crystal orientation on behaviour of columnar grained sea ice
AuthorsC Zhan ; E Evgin ; N K Sinha
Date published1994
AbstractA constitutive model accounting for the effect of crystal orientation on the mechanical behaviour of columnar grained sea ice is used to predict the sea ice behaviour. The effect of crystal orientation on deformation and strength of columnar grained sea ice is looked into. Comparisons between model predictions and available test data are given for the dependence of the uniaxial strength on the loading direction. Firstly the sea ice model is looked at. Next dependence of sea ice behaviour on crystal orientation is discussed.

Effect of silt concentration on the cavitation NPSH curve of a centrifugal pump
AuthorsA Ladouani ; A Khaldi ; B Bekhti
Date published1995
AbstractAn experimental test rig is used to generate information on the effect of silt concentration on N.P.S.H. curves. Silt characteristics are provided. The test rig and the N.P.S.H. measurement procedure are described. The N.P.S.H results are presented. The effects of silt concentration on the cavitation flow rate and on the pump characteristic are discussed. Cavitation in centrifugal pumps discharging silt is accelerated due to rising silt concentration and flow rate leading to lower cavitation flow rates.

Influence of seismic shooting on the lesser sandeel (Ammodytes marinus)
AuthorsArne Hassel ; Tor Knutsen ; John Dalen et al.
Date published2004
AbstractA field experiment on the effect of seismic shooting on the lesser sandeel (Ammodytes marinus) was conducted on the fishing grounds in the southeastern part of the North Sea in May 2002. The distribution and occurrence of sandeel within the seismic shooting region were quantified by grab sampling at night and acoustic surveying during daytime. Based on fishery statistics from the commercial sandeel trawlers operating in the vicinity of the experimental area trends in catch landings of sandeel during the experimental period were also explored.

Potential long-term effects of limiting CO2 and air pollutant emissions on fuels and technologies on the US electricity sector
AuthorsM Miller ; G Hester
Date published2000
AbstractThis paper comprises some 20 overhead projection slides exploring the potential long-term effects of limiting CO2 and air pollutant emissions on fuels and technologies in the US electricity sector. It is concluded that emission reductions need to be co-ordinated with accelerated development of advanced low-emitting technologies and that an analytic process to evaluate the ability of alternative policies to achieve this be undertaken before policy decisions are finalised.

Wave induced forces on a submarine pipeline
AuthorsF Raichlen ; A Watanabe
Date published1997
AbstractThe wave-induced forces on an underwater sewage outfall were investigated using a laboratory model with the pipeline supported off the bottom on a pedestal faced with rock layers. Velocities were measured around the structure upstream and downstream. The virtual mass coefficient and lift coefficient were studied. The porosity of the rock support structure affected neither the virtual mass nor the lift significantly. The effect of the proximity of the structure to the free surface on the virtual mass coefficient was small but the effect on the lift coefficient was significant.

Current forces on a large pier near an existing pier
AuthorsSubrata K Chakrabarti ; Mark McBride
Date published2004
AbstractA new suspension bridge is being built over the Tacoma Narrows Washington. The bridge will be placed on a structure mounted on 2 large concrete caissons which will be exposed to strong currents. The caissons are being built at site while floating and moored in high currents. In order to determine the forces on the caisson due to current a series of scaled physical model tests of one of the caissons was carried out. The forces on the new caisson were measured in the presence of the existing bridge pier and the bottom contours of the Narrows were accurately modeled. The model scale was chosen as 1:100 and the tests were performed for the caisson at different drafts. This paper describes the test setup and measurement system for a series of fixed caisson tests and demonstrates the consistency of the test data. The measured inline drag and transverse lift forces on the fixed caisson at different drafts are presented and the effect of the fluid velocity and flow vorticity on the frequency contents in the forces is discussed. The interaction effect of the neighbouring existing pier on the current forces of the new caisson is investigated. Since the measured forces were applied in the design analysis of the caissons the scaling effect of the model test is also discussed.
