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.

Cavitation scale effects

Authors: Kuiper, G.

Article Type: Research Article

Abstract: Observations of cavitation on a ducted propeller of a VLCC showed abnormal discrepancies with the cavitation pattern, observed on model scale in comparable conditions. To establish the cause of these discrepancies variations of propeller loading, model wake, nuclei content of the fluid and propeller boundary layer were applied. The condition of the propeller boundary layer was found to have a major effect in this case and application of roughness at the leading edge could remove the differences between model and prototype.

Ship hull surface using finite elements

Authors: Pramila, Antti

Article Type: Research Article

Abstract: The paper describes a new method using finite elements for ship hull surface design. A constrained variational principle is proposed in which the fairness criterion is included in the actual functional and the given design coefficients are as constraints. Constraints can be treated by using Lagrangian multipliers or penalty functions. The finite element method is used to solve the variational problem. The final resulting equations in both the cases are derived. Some examples employing rectangular and triangular elements are presented.
