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.

Lowest natural frequencies of structures with rigid-body degrees of freedom

Authors: Hylarides, S.

Article Type: Research Article

Abstract: In this paper three methods are described for the derivation of an invertable stiffness matrix of structures with rigid-body degrees of freedom.

Marine diesel engine exhaust noise

Authors: Janssen, J.H. | Buiten, J.

Article Type: Research Article

Abstract: Data are given on the acceptability of exhaust noise on bridge wings due to the gaspulses of large low-speed marine diesel engines, directly coupled to a constant pitch propeller. ISO noise rating numbers are used. For full speed ahead N 75 is the upper limit of acceptability. The background noise due to auxiliaries is not treated in detail but should be substantially less.

Marine diesel engine exhaust noise

Authors: Buiten, J. | Janssen, J.H.

Article Type: Research Article

Abstract: Simplified scale models are shown to be useful for determining the low-frequency sound transfer properties of an exhaust system of a large low speed marine diesel engine. Experimental results of a full-scale system including silencers closely agree with model results. Ways of constructing, simplifying and investigating the models are indicated. Resistance modelling is discussed. A practical example of calculating the exhaust sound pressure level on a bridge wing due to a typical two-stroke six-cylinder engine with two turbo-superchargers and symmetrical exhaust is treated extensively. Remaining problems are summarized.
