Numerical analysis on added resistance of ship by 3D Green Function Method
AuthorsYoshiyuki Inoue ; N M Golam Zakaria
Date published2005
AbstractIn the present competitive market undertaking a ship mission on schedule and on time is important. Predicting increased resistance of a ship to her governing wave climate is therefore important. At present there are several methods available for dealing with the problem of resistance increase in waves. Most of these methods are based on the calculation of motion responses by Strip Theory or Slender Ship Theory. Although these methods are easy to use and produce acceptable results some of their shortcomings (due to the neglect of 3D hydrodynamic effect) make them unable to provide enough estimation of the increase of resistance in waves especially for fuller ship form vessels. The 3D Green function method with forward speed is now able to estimate better all relevant hydrodynamic responses and is therefore becoming increasingly popular. Linear potential theory is used to describe the fluid motion. The 3D sink-source technique with forward speed is applied to determine hydrodynamic forces for surface ship advancing in waves at constant speed. After solving the motion equation in frequency domain radiation potential due to motion responses is calculated to obtain the total potential of the flow field. Then total potential and its derivatives are obtained to assess the added resistance in waves by near field approach. To show the validity of the numerical code the present numerical results for motion responses and wave loads on ships are compared with experimental data as well as with some numerical results achieved by different approaches. Next the added resistances given by present numerical calculation byX38576 A numerical analysis on the deformation of decomposed granite soil foundation using elasto-plastic model

Development of a range of on-line lubricant and machinery condition sensors for engine monitoring
AuthorsThomas Kent ; Chris Leigh-Jones ; M Hutchings et al.
Date published2004
AbstractLaboratory-based oil analysis programs are currently the accepted method for assuring oil and machinery condition. They provide accurate results in a controlled manner often with additional expert interpretation from the lubricant supplier. The market for off-line lubricant analysis equipment is well served but coming under pressure especially from a requirement to reduce manpower or to continually monitor critical systems. A typical example would be the US Military who need a 70% reduction in manpower for the next generation of front line ships. There is a need to develop reliable and relatively low-cost on-line instrumentation capable of replicating a laboratory analysis providing information on both lubricant and machinery condition. A 3-year research programme was undertaken to investigate the practicality of a number of techniques for monitoring oil and machinery condition realised as an on-line device. Included in this were techniques of magnetometry cyclic voltammetry impedance spectroscopy (Q) capacitance or resistance and microwave. Many of the laboratory techniques used in oil analysis can be replicated in an on-board design. However an on-line realisation of the techniques used for example titration are impractical for reasons of complexity or reliability. Previous research has shown that it is possible to develop on-line instrumentation that does replicate laboratory techniques but these types of systems again have cost and complexity considerations that severely limit theiX44478

Diesel engine design - virtual product development with focus on NVH
AuthorsChristoph Steffens
Date published2007
AbstractNowadays engines face an increased customer expectation regarding noise and vibration. This trend requires the use of simulation tools in early phases of the development process. The virtual engine development process at FEV is described as well as the indispensable interaction with the design and testing activities. FEV has been using virtual development methods for NVH optimisation of engines and transmissions for more than 20 years. Typically attention centres on the optimisation of excitation mechanisms as well as on the structural transfer behaviour vibrations. Fully parameterised simulation models are used in all phases of development. Depending on the current design status of the development the detailing of the simulation models can be adapted. Based on comparative simple rigid body models at the start of the development decisions regarding engine global data like bore stroke cylinder distance and positioning of engine mounts can be made. Later in the development when more design parameters are fixed the depth of simulation models is increased until a fully flexible model allows the NVH behaviour of the complete power unit to be predicted. Such a simulation is carried out using a hybrid simulation approach based on Finite-Element and Multi-Body simulation. On the one side excitation mechanisms are treated.

Improved insight in roll motions of ultradeep water FPSOs based on a comparison of calculations model tests and full-scale measurements on the Girassol FPSO

AbstractThe roll motions of ultradeep water FPSOs are examined based on a comparison of calculations model tests and full-scale measurements on the Girassol FPSO. Full-scale measurements of the motions of the Girassol FPSO were taken over a one-year period. During this same period also vessel draft wave height and wave direction were recorded. This allows motion transfer functions to be calculated as a function of the FPSO loading condition. A comparison is made between measured full-scale response and the combination of diffraction analysis and model tests. Wave frequency motions in six degrees of freedom and the heading have been measured on board of the Girassol FPSO located West of Africa. The monitoring campaign also includes wave measurements by means of a directional wave rider buoy as well as the drafts trim and heel. A new methodology is presented to compare the results of the theoretical analysis in long-crested waves with the measurements offshore in short-crested waves. Results are presented and discussed and conclusions drawn.

Temporal and spatial variation in predation on juvenile herring (Clupea harengus L) by Northeast Arctic cod (Gadus morhua L) in the Barents Sea in 1984-1997
AuthorsGeir Odd Johansen
Date published2002
AbstractThe main purpose of this work is to identify important periods and geographical areas for predation on juvenile herring by cod in the Barents Sea based on stomach content data from cod covering the period 1984-1997. The study focuses on broad scale temporal and spatial trends. The trends are related to population dynamics and distribution of juvenile herring and climatic variation in the Barents Sea. The analyses cover: (1) year-to-year and seasonal variation in the occurrence of herring in cod stomachs (2) the relationship between occurrence of herring in cod stomachs and abundance of juvenile herring and capelin (3) identification of the main geographical areas for predation by cod on juvenile herring and its seasonal variation and (4) climatic effects on the main geographical areas for predation by cod on juvenile herring. The results are discussed in the context of the broad scale ecosystem dynamics in the Barents Sea during the period of interest.
