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.

Research on bulbous bow ships

Authors: van Lammeren, W.P.A. | Muntjewerf, J.J.

Article Type: Research Article

Abstract: Model tests were carried out to determine the still water performance of a 24,000 DWT bulk carrier, provided with a large bulbous bow of hemi-spherical form. A comparison of the results with those of the same ship model, however, with conventional bow was made both for the loaded and ballast condition. Considerable savings in power were found for the ship with bulbous bow in the ballast condition. In the loaded condition practically no influence of the bulbous bow could be established. The results were checked on possible laminar flow effects by carrying out additional tests with extra turbulence … Show more

Model tests with nozzles and steering nozzles for trawlers

Authors: Muntjewerf, J.J.

Article Type: Research Article

Abstract: With a trawler model several nozzle propeller arrangements were tested in still water both free running and when trawling. Special attention was paid to turning ability and rudder head torques to be expected with steering nozzles.

The lateral control response of a hydroskimmer

Authors: Bluston, H.S.

Article Type: Research Article

Abstract: Methods are given for obtaining the Hydroskimmer response for the three lateral degrees of freedom with rudder and variable nozzle control systems. Solutions are obtained in terms of Laplace Transforms for any control input and in real time for a step control input. The solutions for the step input depend on functions of the craft stability and control derivatives and these functions are presented graphically in terms of the fundamental craft parameters. The parameters considered are the rudder chord, rudder area, rudder longitudinal distance from the C.G., craft beam, jet thickness and jet exit height. Skeg and water depression effects … Show more
