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.

Variational principles associated with ship motions in waves

Authors: Isshiki, H.

Article Type: Research Article

Abstract: General variational principles for linear water waves are obtained. Reasonable algorithms to calculate hydrodynamic quantities, which are important in discussing ship motions in waves, are obtained from the standpoint of the variational principles. A general form of the equation of ship motions in ocean waves is discussed. A general theory of one-dimensional tidal waves is also discussed, and the corresponding variational principle is obtained. Using this principle, a simple numerical example is given to show the character and importance of the variational principle.
