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.

Cancellation effect and parameter identifiability of ship steering dynamics

Authors: Hwang, Wei-Yuan

Article Type: Research Article

Abstract: The identifiability problem of hydrodynamic coefficients in a nonlinear ship maneuvering model is presented. The contribution plot of hydrodynamic coefficients is analyzed to show the cancellation effect. Slender-body theory is applied to show that the cancellation effect is inherent for the steering dynamics of ships. Parameter transformation is introduced to overcome the difficulty in the coefficient estimation of linear terms. A practical approach is suggested to identify the nonlinear dynamics of ships.

Ship-motions with forward speed in infinite depth

Authors: Guevel, P. | Bougis, J.

Article Type: Research Article

Abstract: We propose in this paper two 3D methods to solve the diffraction-radiation problem with forward speed. This physically complex problem is reduced to the determination of the potential of the flow around the immersed part of the body. Boundary conditions are linearized and calculated at the mean boundary position. The total velocity potential is obtained by summing incident, diffraction and radiation velocity potentials. Each problem is resolved by two 3D singularities methods (mixed distribution and sources distribution). The Green function is determined with the almost perfect fluid assumption, or with the perfect fluid assumption and a radiation condition at … Show more
