“Why a Naval Architect likes an electric ship” for SPEEDAM 2008 Ischia, Italy June 11th – 13th, 2008
2008 International Symposium on Power Electronics Electrical Drives Automation and Motion, 2008Co-Authors: Rick HepburnAbstract:This paper examines why an electric ship is so desirable to a Naval Architect. A Naval Architect appreciates arrangeable volume, arrangeable equipment, large cargo capacity, large endurance, low thermal management, lots of bulkheads, few hull penetrations, equipment that is flexible and has multi-uses. Naval Architects also need equipment that is reliable, available, and maintainable to reduce impacts to required ship accesses and personnel required to do maintenance. The fundamental characteristic of electric propulsion is an enabling topology that matches well to the needs of the Naval Architect.

Heave and Pitch Motion Performances of a Ship Towing System Incorporated with Symmetrical Bridle Towline Model
EPI International Journal of Engineering, 2019Co-Authors: Ahmad Fitriadhy, Nur Adlina Aldin, Nurul Aqilah Mansor, Nur Aqilah Hanis ZalizanAbstract:An investigation on vertical motion characteristics of a ship towing system incorporated with symmetrical bridle towline configuration set a real challenge for the Naval Architect engineer. This paper presents a Computational Fluid Dynamic (CFD) approach to analyse heave and pitch motion performances in waves. Several towing parameters such as various towline length and towing’s velocity have been taken into account. Here, 1B (barge) is employed in the simulation; and designated as a towed ship. The results revealed that the subsequent increase of the towline lengths has been basically proportional with the increase of her heave motion; while inversely decrease in pitch motions. In addition, the effect of the extending towline length = 1.0 to 3.0 resulted in insignificant effect to the towline tension. However, the increase of the towing’s velocity from 0.509 m/s to 0.728 m/s has led to significantly increase her heave motion and the towline tension by 40.46% and 24%, respectively; meanwhile, the pitch motion barge has sufficiently decreased by 35.94%. This simulation has been beneficial for the towing operator to ensure a higher level of the safety navigation of ship towing system.

a systematic methodology to assess the impact of human factors in ship design
Applied Mathematical Modelling, 2009Co-Authors: Steven Deere, E R Galea, Peter J LawrenceAbstract:Evaluating ship layout for human factors (HF) issues using simulation software such as maritimeEXODUS can be a long and complex process. The analysis requires the identification of relevant evaluation scenarios; encompassing evacuation and normal operations; the development of appropriate measures which can be used to gauge the performance of crew and vessel and finally; the interpretation of considerable simulation data. Currently, the only agreed guidelines for evaluating HFs performance of ship design relate to evacuation and so conclusions drawn concerning the overall suitability of a ship design by one Naval Architect can be quite different from those of another. The complexity of the task grows as the size and complexity of the vessel increases and as the number and type of evaluation scenarios considered increases. Equally, it can be extremely difficult for fleet operators to set HFs design objectives for new vessel concepts. The challenge for Naval Architects is to develop a procedure that allows both accurate and rapid assessment of HFs issues associated with vessel layout and crew operating procedures. In this paper we present a systematic and transparent methodology for assessing the HF performance of ship design which is both discriminating and diagnostic. The methodology is demonstrated using two variants of a hypothetical Naval ship.

CDVE - Partner selection for interfirm collaboration: the context of ship design
Lecture Notes in Computer Science, 2009Co-Authors: Marina Solesvik, Sylvia EnchevaAbstract:There is a growing body of research devoted to the issues of cooperative design. However, there are still gaps in the existing knowledge on partner selection for cooperation. This paper intends to explore partner selection issues in the context of collaborative ship design. The study aims to fill a gap in the partner selection literature by proposing a quantitative technique based on formal concept analysis. An illustrative example of the selection of a partner for a project-based alliance in a Naval Architect firm is presented. The study has implications for practitioners and researchers.

8 – Intact stability regulations I
Ship Hydrostatics and Stability, 2003Co-Authors: Adrian BiranAbstract:Publisher Summary Analyzing the data of vessels that behaved well various researchers and regulatory bodies prescribed criteria for deciding if the stability is satisfactory. This chapter presents examples of such criteria. It also presents man-made laws. Laws of nature act independently of man's will and they always govern the phenomena to which they apply. If a certain ship fulfils the requirements of given regulations, it does not mean that the ship can survive all challenges, but its chances of survival are good because stability regulations are based on considerable experience and reasonable theoretic models. Stability regulations are, in fact, codes of practice that provide reasonably safety margins. All stability regulations specify a number of loading conditions for which calculations must be carried out. Some regulations add a sentence like “and any other condition that may be more dangerous”. It is the duty of the Naval Architect in charge of the project to identify such situations, if they exist, and check if the stability criteria are met for them.
