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.

On the propeller efficiency calculated by lifting line theories

Authors: Dyne, G.

Article Type: Research Article

Abstract: Theoretical investigations recently reported in the literature claim that it is possible to increase the propeller efficiency above the so called Lerbs’s optimum by increasing the tip load. The critical examination given below indicates however that this result is questionable, the main reason being inconsistencies in the lifting line theory. Thus check calculations show that the thrust derived from the momentum law is lower than the thrust computed by the law of Kutta-Joukowsky, especially for tip loaded propellers. To get the same thrust by the two principles a certain reduction of the pitch of the helical tip vortices is necessary.

Wave-induced motions and loads of tug-barge units, some design aspects

Authors: van Sluijs, M.F.

Article Type: Research Article

Abstract: This article reviews the results and methods associated with model tests in waves on seagoing tug-barge units. It considers the analysis of the observed phenomena which is based on experience gained from physical model tests carried out at the NSMB, the Wageningen/Ede Laboratories of the Maritime Research Institute Netherlands (MARIN). The results presented in this paper are based upon a limited number of model experiments and must be applied only with proper reserve. Although the present state of the art is that tests are still the only realistic method of predicting the behaviour and the loads that occur in … Show more

Prediction of extreme response values for ocean going vessels

Authors: Langley, R.S.

Article Type: Research Article

Abstract: The response of an ocean going vessel can often be represented as a Gaussian stochastic process. This paper presents a method of predicting the extreme values of such a process, allowance being made for the clumping of peaks. The method draws upon the considerable amount of published literature which is available concerning the limiting decay rate of first crossing probability of a linear oscillator, which is then modified to be applicable to a process having a general spectrum. Results of this method are compared with those of time domain simulation and much closer agreement is found than is obtained from … Show more
