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.

Reduction of the development of bilge vortices by discharge of air into the boundary layer

Authors: Kostilainen, V.

Article Type: Research Article

Abstract: The development of bilge vortices can be reduced by discharging small amounts of air into the boundary layer. Air bubbles turn the downward cross flow, thus reducing streamline convergence and vortex sheet separation near the bilge. The results of model experiments with a full ship form are presented. It is concluded that the system improves the wake distribution and it may be a useful precaution against propeller excited vibrations of full ship forms.

Calculation of the boundary-layer flow around three ship afterbodies

Authors: Raven, H.C.

Article Type: Research Article

Abstract: A description is given of a differential method for the calculation of the boundary layer on ship hulls, and its application to three slightly different ship afterbodies. The boundary layer equations are solved in a curvilinear coordinate system, together with two turbulence model equations. The results are compared with experimental data. The correspondence appears to be excellent on the greater part of the hull. In some regions, differences are present, which result mainly from the neglection of the potential flow-boundary layer interaction. The prediction of bilge vortex formation is examined, and the incorporation of higher order effects in the method … Show more
