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.

Coupled transverse shaft vibrations of modern ships

Authors: Vassilopoulos, L. | Bradshaw, R.

Article Type: Research Article

Abstract: The design of main propulsion shafting systems for modern ships, such as VLCC’s, LNG carriers and high-speed containerships, is to a great extent dictated by the requirement of vibration-free performance in service. It is the purpose of this paper to present a method for predicting analytically in the design stage the coupled transverse vibration characteristics of a given propulsion shaft system and to illustrate it with typical examples. A brief description of the basic problem is first given and this is followed by a review of earlier theoretical work in this field. The transfer matrix approach for the solution … Show more

Use of two-dimensional unsteady flow theory with low aspect-ratio blades

Authors: Murray, M.T.

Article Type: Research Article

Abstract: It is known that if two-dimensional aerofoil theory is used to calculate the mean forces on a marine propeller blade, the answer obtained is likely to over-estimate the true answer by a factor of typically three. It is shown that when unsteady forces (at blade-rate frequency) are being calculated, the use of unsteady two-dimensional aerofoil theory is much more acceptable, being associated with errors of about 25%. It is pointed out that the more accurate unsteady lifting-surface theory is prohibitively expensive for use regularly as a design tool. and further, that the accuracy of the answer may be limited in … Show more
