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.

Extrapolation methods of resistance tests results of shipmodels

Authors: Krezelewski, M. | Welnicki, W.

Article Type: Research Article

Abstract: In this paper the relations between the total resistance coefficient and the coefficient of pressure, friction, wave and viscosity resistance have been obtained on the basis of equations normalization for uncompressible fluid with the boundary conditions as well as a normalization of some general expressions for hydrodynamic reactions affecting the ships. This constitutes the foundation for a critical analysis of the ship’s resistance extrapolation methods. It has been proved that ah resistance coefficients can be functions of Froude, or Reynolds number simultaneously. These relations have created grounds for constructing four new equivalent extrapolation methods in which all extrapolation … Show more

Methods for computing stiffness and damping properties of main propulsion thrust bearings

Authors: Vassilopoulos, L.

Article Type: Research Article

Abstract: The study of longitudinal shaft vibrations of propulsion shafting systems requires knowledge of the thrust bearing stiffness and damping properties. The paper presents a step-by-step engineering procedure for determining these parameters using simplified structural model and elementary lubrication theory, but the utility of finite element and finite difference methods for more refined assessments is also mentioned. The paper deals only with integral bearings of the hydrodynamic, tilting-pad type. The net bearing stiffness is obtained by linearizing the behavior of its various elements, such as the collar, oil film, pads, buttons, links, rings, shims, housing and flanges. The derived … Show more
