The journal International Shipbuilding Progress (ISP) was founded in 1954. Each year two issues appear (in March and September). Publications submitted to ISP should describe scientific work of high international standards, advancing subjects related to the field of Marine Technology, such as:

  • - Concept development
    - General design of ships and offshore objects
    - Ship and offshore structural design
    - Hydro-mechanics and -dynamics
    - Maritime engineering and machinery systems
    - Production processes of all types of ships and other objects intended for marine use
    - Production technology and material science
    - Shipping science, economics, and all directly related subjects
    - Ship operations
    - Offshore and ocean engineering in relation to the marine environment
    - Marine safety
    - Efficiency, lifecycle, and  environment
    - Ice-related aspects for ships and offshore objects.

  • The contents of the papers may be of a fundamental or of an applied scientific nature and must be of the highest novelty and rigor.

A power prediction method and its application to small ships

Authors: van Oortmerssen, G.

Article Type: Research Article

Abstract: A mathematical model is derived by which it is possible to describe the resistance and propulsion properties of ships as a function of the Froude number, the Reynolds number and the general form and propeller parameters. The coefficients of the mathematical model have been calculated for small ships such as trawlers and tugs from random tank data, obtained from the N.S.M.B.-statistics. With the present method it is possible to make an approximation of the resistance and required power which is accurate enough for design purposes. The method is suitable for programming.

On the stability of ship motion in regular oblique waves

Authors: Haddara, M.R.

Article Type: Research Article

Abstract: The nonlinear equations of motion of a ship sailing in regular oblique waves are formulated and an analytical method is developed to obtain an approximate solution for them. The stability of the steady-state solution is investigated by examining the behavior of the solution of the equations of the first variation of the equations of motion. This study shows that the existence of unstable motion is predicted for certain cases if we take account of nonlinearities in the equations of motion. This instability is very sensitive to variations in the nonlinear damping coefficient in roll.
