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.

The effect of a nozzle on steering characteristics

Authors: van Gunsteren, L.A. | van Gunsteren, F.F.

Article Type: Research Article

Abstract: A method is presented for predicting how the steering characteristics of a ship are affected by fitting a fixed nozzle. The presence of a nozzle upstream appears to have a significant effect on the rudder forces. Full-scale manoeuvring trials carried out with two twin-screw tugs, one with open propellers and the other equipped with nozzles, confirm the predicted trends. It is concluded that propeller, nozzle and rudder should be designed in an integrated way to ensure that an optimum solution is obtained with regard to both propulsive and steering qualities.

A proposal of a method to specify the permissible region of instability in the steering characteristics of ships

Authors: Koyama, T.

Article Type: Research Article

Abstract: The way to specify the permissible region of instability of ships is proposed from the viewpoint that ships should be controllable for any human operator without difficulty. In the case of the steering of the ship (course keeping), where the motions of ships are small, we can approach that problem with a linear equation. The importance of the time constant T. as well as the proportionality coefficient K, was stressed. Assuming a very simple human operator model, which can be followed by any human operator, the permissible region was specified as a combination of T and K.

Maritime transportation of containerized cargo

Authors: Knobbout, J.A.

Article Type: Research Article

Abstract: Condensation may cause severe damage to cargo loaded in containers. The condensation phenomenon is discussed in general. Some major important factors with regard to the condensation risk have been evaluated theoretically as well as practically. A certain transportation situation viz. the transport of tins in cardboard boxes loaded in containers from Australia to Europe v.v. is simulated with the help of an electronic computer. The results from these calculations are compared with measurements that could be performed under normal practical conditions. Recommendations are given concerning the measures that can be taken to avoid or to minimize condensation. Proposals for … Show more
