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.

Generalized complex damping and spectral bandwidths for seismic responses of offshore platforms

Authors: Chen, Yung-Hsiang

Article Type: Research Article

Abstract: An efficient method to compute the seismic response of an offshore platform in still water is presented. The structure is modelled by a three-dimensional space frame with lumped parameters and the dynamic response is determined by the mode-superposition method. Both the effects of the nonlinear drag force and the mode-damping coupling are also taken into account. The random nonlinear drag force is linearized by the method of the least square in statistical sense, and the mode-damping coupling is uncoupled by use of the concept of the generalized complex damping. As a consequence some important spectral bandwidths for all vibrational modes … Show more

Effects of distributed roughness on the skin friction of ships

Authors: Kauczynski, W. | Walderhaug, H.

Article Type: Research Article

Abstract: In order to study the influence of different distributions of paint roughness on ship skin friction resistance a calculation method has been developed. The method is based on conformal mapping technique for describing the ship form and uses a momentum – integral method for calculation of three-dimensional turbulent boundary layer characteristics. The velocity shift due to paint roughness has been determined by experiments. Calculations for five Series 60 ships have been carried out and diagrams for practical applications are presented. Some examples of local roughness effect calculations and other possible applications of the presented method are also included.
