Mauro, F. (author), Kana, A.A. (author)The focus on digitalisation in manufacturing is spreading to other industry fields, including large and complex objects like ships. Such interest introduces the concept of Digital Twins in supporting designers and operators through the whole ship-life cycle. However, the term Digital Twin is typically abused in the shipping industry, many...review 2023

Odendaal, Kirsten (author), Alkemade, Aaron (author), Kana, A.A. (author)The adverse human contribution to global climate change has forced the yachting industry to acknowledge the need to reduce its environmental impact due to the client's increasing pressure and potential future regulations to limit the ecological effects. Unfortunately, current real-world data presents a significant disparity between predicted...journal article 2023

Milatz, Bas (author), de Winter, Roy (author), van de Ridder, Jelle D.J. (author), van Engeland, Martijn (author), Mauro, F. (author), Kana, A.A. (author)The prediction of the statutory attained subdivision index is a challenging issue for the initial design of ships due to the design freedom offered by a probabilistic damage stability assessment. To this end, optimisation techniques integrated with a parametric model of the internal layout may generate a preliminary subdivision design,...journal article 2023

Doornebos, Patryk (author), Francis, Moreno (author), le Poole, J.J. (author), Kana, A.A. (author)This paper explores the design and feasibility of a 200-passenger, 30- to 40-knot emission-free ferry as a potential variant of the traditionally powered Coastal Cruiser 200 ferry currently operating in the Chinese Pearl River Delta. The Pearl River Delta is one of China’s most densely urbanized regions and faces numerous social, health, and...journal article 2023

le Poole, J.J. (author), Duchateau, E.A.E. (author), Hopman, J.J. (author), Kana, A.A. (author)Design rationale is a promising way of capturing design decisions and considerations for later retrieval and traceability to improve collaborative design decision-making. To achieve these perceived benefits for early-stage complex ship design, this paper first elaborates on the development of a proof-of-concept design rationale method. The...journal article 2023

De Kwant, Jochem (author), Hekkenberg, R.G. (author), Souflis-Rigas, A.S.R. (author), Kana, A.A. (author)This article examines the potential implications of using iron powder as an alternative fuel on the design and performance of container ships. Iron powder is a relatively new alternative energy carrier and one in which little research has been done into the application on-board vessels as part of the maritime energy transition. The key...journal article 2023

Zwart, Robert H. (author), Bogaard, Jordi (author), Kana, A.A. (author)Trim optimization improves the energy efficiency of ships, thus reducing operational costs and emissions; however, trim tables are only available for a limited number of ships. There is thus a desire to develop additional, more accurate trim tables without the need for expensive model testing. The objective of this research was to develop a...journal article 2023

le Poole, J.J. (author), Duchateau, E.A.E. (author), Hopman, J.J. (author), Kana, A.A. (author)The development of concept designs during early warship design stages is essential to inform stakeholder dialogues on technical feasibility, affordability, and risk. One of the key aspects of warship concept designs is the layout of systems in the overall arrangement. The adoption of real-time design processes, such as concurrent design, require...journal article 2022

Streng, J.E. (author), Kana, A.A. (author), Verbaan, J.H. (author), Barendregt, I.P. (author), Hopman, J.J. (author)In order to reduce fossil fuel consumption of the Royal Netherlands Navy (RNLN) by 70% in 2050, the use of alternative fuels on the large naval surface vessels is examined. This paper examines the implications for the design and operational effectiveness of these vessels by performing two case studies of the Zeven Provinci¨en air defence and...journal article 2022

(author), Zwaginga, J.J. (author)This paper describes two new modular ship design activities for graduate education at Delft University of Technology that have been developed during COVID. First, a new 2-hour hybrid format (in-person and virtual participation) game was designed to teach students modular design for offshore support vessels (OSVs). Second, an 8-week MSc-level...conference paper 2022

Valcalda, A. (author), de Koningh, D. (author), Kana, A.A. (author)The introduction of the ‘Safe Return to Port’ (SRtP) regulations strongly impacted the design of passenger ships. To meet the functional requirements of these regulations, the systems on board reached an extreme level of complexity in terms of redundancy and segregation, considerably increasing the difficulties to assess the compliance of the...journal article 2022
