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.

Limit cycles in diesel/controllable pitch propeller propulsion systems using load control

Authors: Parsons, M.G. | Wu, J.Y.-C.

Article Type: Research Article

Abstract: Marine diesel/controllable pitch propeller propulsion systems using load control can experience limit cycling or hunting. Simplified fourth-order and eight-order models are developed to study the properties of these control systems. The backlash inherent in mechanical-hydraulic type engine governors is taken as the principal nonlinearity in the system. Describing function analysis and digital simulation are used to demonstrate the existence and characteristics of the limit cycles. The numerical example is based upon the characteristics of a 1000 foot Great Lakes bulk carrier with 8000 horsepower per shaft. It is shown that an active load control feature, which couples the pitch control … Show more
