The journal International Shipbuilding Progress (ISP) was founded in 1954. Each year four issues appear (in April, July, September and December). 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.

Abstract: BACKGROUND: Understanding how and why the development of conceptual ship designs sometimes become ineffective is essential for ship design firms. Our proposition is that in many projects, uncertainty influences negatively the effectiveness of the decision-making process. OBJECTIVE: The objective of this article is to quantify the perception of uncertainty in conceptual ship design processes. METHODS: In this article, we propose a research model to study such a phenomenon. The research model is tested using multivariate regression analysis, building on a survey conducted among 23 shipping companies. RESULTS: Our model suggests that 14% (R …2 ) of the variability in the effectiveness of decision-making processes in ship design can be explained by changes in the perception of uncertainty. We can extract three interesting insights from this research work for the ship design practitioners as to how to improve the effectiveness of their design processes: (i) put more effort into the contextual factors affecting the ship design process, (ii) improve the communication with vessel owners and other stakeholders, and (iii) improve the agility of the design process. CONCLUSIONS: This study contributes to research on uncertainty in ship design processes by: (a) proposing an investigative model, (b) developing and testing a survey instrument and (c) running a multivariate regression analysis to study the effect of perceived uncertainty on the effectiveness of decision-making processes in conceptual ship design.
