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.

Wave resistance and lift on cylinders by a coupled element technique

Authors: Eatock Taylor, R. | Wu, G.X.

Article Type: Research Article

Abstract: This paper presents a new application of one of the most promising methods in ship hydrodynamics to free surface flow problems. It concerns a body having uniform forward speed in an incompressible and inviscid fluid. The method combines localised finite elements in the near field with representation by a boundary integral equation in the far field. The free surface condition is linearised but the body surface boundary condition is satisfied exactly. Calculations for different submerged cylinders are made, as a means of assessing the effectiveness of the new approach. Agreement with existing results is excellent, and it is concluded that … Show more

The design of autopilots using the pseudo-derivative feedback algorithm

Authors: Flower, J.O. | Sparrius, J.R.

Article Type: Research Article

Abstract: This paper is concerned with a simple method for the design of autopilots for ships. The method used is based on an automatic-control-design technique due to Phelan [1,2], based on physical arguments, and termed pseudo-derivative feedback control. When properly tuned (a comparatively easy task) such controllers are known to possess good transient behaviour when their set-point is altered and to be extremely good at alleviating output deviations due to step-changes imposed by external loads disturbing the system. This latter property appears to carry, over when the disturbances are sinusoidal in form and, by implication, stochastic in form. Such behaviour is … Show more
