Study on side structure resistance to ship-ship collisions

Ships and Offshore Structures, 2007
Double hull (DH) tankers may be more effective than single hull (SH) tankers in pollution prevention because they have a second barrier, the inner skin, to oil outflow in the event of side damage. The actual effect of DHs calls for quantitative study. This paper presents a comparative study on the side structure resistance to collisions.

Ship Resistance and Propulsion

2011
Ship Resistance and Propulsion provides a comprehensive approach to evaluating ship resistance and propulsion. Informed by applied research, including experimental and CFD techniques, this book provides guidance for the practical estimation of ship propulsive power for a range of ship types.

Added resistance of ships in waves^†

Ship Technology Research, 2015
Added resistance of ships in waves is determined by a newly developed potential flow method, a Rankine source method, a strip method, and by RANS (Reynolds-averaged Navier-Stokes) equations solvers. For 10 ships, results of all these methods are compared with each other, with published computed and experimental results, and with approximation formulae ...

Skin Friction Resistance of Ships

Journal of Ship Research, 1957
The International Towing Tank Conference (ITTC) is to hold its 8th meeting in Madrid in September of this year. One of the subjects to be discussed will be the perennial one of how to estimate the resistance of a ship from that measured on a small-scale model in a towing tank.

Analysis of viscous ship resistance

International Shipbuilding Progress, 1954
It has been said that “our knowledge of viscous pressure resistance is completely inadequate”. The author thinks, however, that the physical mechanism of resistance caused by viscosity can be stated and that sufficient theoretical and experimental material on this question is available to start a statistical evaluation.

Numerical Estimation of Ship Resistance

2011
Introduction The appeal of a numerical method for estimating ship hull resistance is in the ability to seek the ‘best’ solution from many variations in shape. Such a hull design optimisation process has the potential to find better solutions more rapidly than a conventional design cycle using scale models and associated towing tank tests ...

The Wave Resistance of Ships

1973
Publisher Summary Waves follow a moving ship and the propagation of these waves is associated with the presence of a gravitational field. Water is endowed with viscosity, and anybody moving through a viscous fluid, experiences a resistance, partly because of tangentially acting stresses on the body, but partly also because boundary-layer growth, and ...

Ship resistance in thick brash ice

Cold Regions Science and Technology, 1980
Abstract The mechanical properties of thick brash ice are considered, with special emphasis on the friction angle ф for a linear Mohr-Coulomb failure criterion. The static equilibrium of a uniform brash layer is discussed, and the internal stresses are given for neutral, active, and passive stress states.
