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.

The influence of the torsional rigidity of plate stiffeners on plate effectiveness

Authors: Williams, D.G.

Article Type: Research Article

Abstract: The torsional rigidities of a bulb stiffener and an “equivalent angle” stiffener are examined for the influence of the following parameters: end restraint; position of shear centre from enforced centre of rotation; web distortion; axial load; and distance between restraints. An effective normal, rotational restraint is evaluated for a stiffened panel in a system of panels, and a loss of plating effectiveness is obtained for three types of initial distortion of the panels. The study shows, for the configurations examined, that the cross-sectional shape of the stiffeners has very little effect on plate effectiveness, and that plate effectiveness … Show more

Results of systematic model tests of a stern trawler side launching

Authors: Zdybek, T.

Article Type: Research Article

Abstract: A series of model experiments has been conducted with a stern trawler model, in which the main parameters governing the motion of a side launched vessel were systematically varied. The paper presents the results of the tests in the form of dimensionless equations to enable launching characteristics of similar vessels to be predicted in advance. Practical applications of the results are discussed.

Practical aspects in the design of high-speed small propellers

Authors: Kruppa, C.

Article Type: Research Article

Abstract: Methodical series results and theoretical methods are discussed as suitable means of design, both for large blade area ratio noncavitating and fully cavitating propellers. The most common applications and aspects of installation are described, emphasis being placed on propellers which operate little submerged or even surface piercing. High-speed controllable pitch propeller applications and special problems encountered in model testing are dealt with.

A study of the extreme variance of rolling motion in random oblique waves

Authors: Haddara, M.R.

Article Type: Research Article

Abstract: The stability and stationary solution of the mean and variance linear differential equations for a ship rolling in random oblique waves are discussed. It is found that unstable motion may exist, under certain conditions, if the sea spectrum is peaked near one of the Mathieu’s equation resonance frequencies. The stationary solution is derived for the stabile case. Order statistics is used to study its extreme value distribution. The solution for the nonlinear problem is also outlined.
