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.

Controllable pitch propellers, their suitability and economy for large seagoing ships propelled by conventional, directly-coupled engines

Authors: Kapsenberg, C.

Article Type: Research Article

Abstract: Models of a tanker of 32,000 t.dw., 16,000 BHP and a freighter of 12,300 t.dw., 7,800 BHP, each propelled alternatively by a fixed blade propeller and a controllable pitch propeller, were extensively tested in the towing tank. In addition to the hydrodynamic results some thought is given to the possible consequences of an engine room arrangement in which the main engine is constantly turning in the same direction with only restricted variation in the number of rpm. The economic aspects of controllable pitch propellers are also considered.

Natural frequencies of free vertical ship vibrations

Authors: Vreugdenhil, C.B.

Article Type: Research Article

Abstract: The present investigation deals with some problems in the calculation of ship-hull vibrations. For practical purposes only the determination of natural frequencies of free vertical vibrations is considered. Especially one assumption, that the influence of the mass-moment of inertia is negligible, is investigated. Therefore a number of computation-methods is considered on their possibility of taking that influence into account. Two methods appear to be useful: (1) the Holzer-Myklestad method (Prohl’s method); (2) a method using influence functions, that has not yet been applied to ship vibration. Computations with these two methods were carried out on … Show more
