“…Currently, investment projects dedicated to autonomous container short-sea shipping are subjects of growing interest, mainly due to the continuously growing volume of container transport [46]. One of the projects related to autonomous container ships is the ReVolt, where a concept vessel designed by DNV GL along with its model have been developed [17].…”

The development of autonomous ship technology is currently in focus worldwide and the literature on this topic is growing. However, an in-depth cost and benefit estimation of such endeavours is in its infancy. With this systematic literature review, we present the state-of-the-art system regarding costs and benefits of the operation of prospective autonomous merchant ships with an objective for identifying contemporary research activities concerning an estimation of operating, voyage, and capital costs in prospective, autonomous shipping and vessel platooning. Additionally, the paper outlines research gaps and the need for more detailed business models for operating autonomous ships. Results reveal that valid financial models of autonomous shipping are lacking and there is significant uncertainty affecting the cost estimates, rendering only a reliable evaluation of specific case studies. The findings of this paper may be found relevant not only by academia, but also organisations considering to undertake a challenge of implementing Maritime Autonomous Surface Ships in their operations.

“…The designer will also have to consider other objectives, beyond the optimised ones that will need to be satisfied. This will be achieved by integrating the present tool in the Holistic Optimisation Framework (Papanikolaou 2010;Priftis et al 2018), linked with the other parametric models.…”

“…Their arsenal is equipped with a plethora of methods, ranging from extremely fast and simple to very sophisticated, computationally intensive but highly accurate; have for the first time enabled the designers to implement a really holistic design optimisation (Papanikolaou 2010). This enables the decision-maker to assess the impact of the preferences expressed and trade-off between the various objectives Nikolopoulos and Boulougouris 2018;Priftis et al 2018). As all decisions taken are strongly or loosely linked with the allocation of the spaces onboard the ship, the optimisation of the arrangement has the potential to improve substantially the design of the vessel.…”

Modern optimisation methodologies have revolutionised the engineering sector and pave the way for innovation. In ship design, this has been spearheaded by the introduction of the Holistic Design approach that allows more attributes and performances of the end product to be assessed accurately and concurrently even at the early design phase. In this respect, the authors present herein a methodology based on the optimisation of the functionalities that the general arrangement needs to provide (in this case; adjacency, noise and evacuation flow). The methodology allows for a large optimisation space, several objectives and intrinsic control by the user at all the stages. By re-arranging the location of the spaces onboard, in relation to their position on the hull as well as between themselves, significant improvements can be achieved. More functional objectives can be incorporated through modularity and penalty functions, keeping the overall process simple and flexible to adapt to fluid early design requirements.

“…This is the approach investigated and further developed currently in the framework of the European Union funded HOLISHIP project (HOLISHIP, 2016(HOLISHIP, -2020. Based on previous works by the authors (Priftis et al, 2018a, Priftis et al, 2018b, the methodology starts with the creation of a detailed parametric model that captures both the main particulars and the internal compartmentation of the vessel, along with the integration of a number of numerical tools, purposely developed in order to determine each variant's performance. This allows the evaluation of a multitude of merit functions and design constraints, all part of the optimisation problem.…”

The paper addresses the parametric design and multi-objective optimisation of ships under uncertainty, applying the Holistic Optimisation Design Approach. The methodology starts with the creation of a detailed parametric model that captures both the external and internal geometric characteristics of the vessel, along with the integration of a number of numerical tools, purposely developed in order to determine each variant's performance. This allows the evaluation of a multitude of merit functions and design constraints, all part of the optimisation problem. In contrast to previous approaches, the uncertainties introduced by the physical and financial environment are incorporated in the model, providing a more realistic representation of the solution space to the decision maker. The developed methodology is applied on a case study of a Ro-Pax ship, optimised in the concept design phase with regard to the minimisation of the total resistance, required freight rate and building cost.
