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 effectiveness of a bow thruster at low and medium ship speeds

Authors: Norrby, Ralph

Article Type: Research Article

Abstract: The manoeuvreability of a ship is poor at low speed, but it can be improved considerably by installing a bow thruster. The model tests which KMW have carried out at HyA show that the thrust from the bow thruster jet does not change with speed. However, the pressure distribution on the hull is changed by the jet so that the resulting side force and turning moment vary with the ship speed. For a 60,000 TDW tanker with a 1500 HP bow thruster the turning moment decreases to 50% at 4 knots and increases again for higher speeds. At 15 … Show more

Analysis of the modified strip theory for the calculation of ship motions and wave bending moments

Authors: Gerritsma, J. | Beukelman, W.

Article Type: Research Article

Abstract: A detailed comparison is made of calculated and measured ship responses to regular head waves. The comparison includes an analysis of the hydrodynamic force distribution along the length of an oscillating ship model in still water, the wave force distribution on a restrained model in waves and the wave bending moment distribution in regular head waves. The calculations are carried out according to the modified strip theory, which includes some important forward speed effects. The analysis shows that the calculations are sufficiently accurate for practical purposes, at least in the frequency range which is of interest.

Universal propeller charts for ship design

Authors: Volker,

Article Type: Research Article

Abstract: When designing a ship, we first have to settle the efficiency of the screw propeller, its number of revolutions and its diameter. The decision about the other details of the screw will follow when the ship is under construction. Two propeller charts are offered which may easily serve all design purposes. An example of a full-power thrust curve for a tug is given considering fixed and variable pitch propellers. The problem of shallow immersion of screws is touched. Throughout the new symbols of the International Tank Towing Conference are used.
