“…A study in [69] examines the conversion of a cargo ship used in SSS in Norwegian waters into an autonomous ship, along with the design of the crewless ships of the future. It was concluded that when compared to other shipping types, such as ocean-going vessels, MASS adoption on SSS routes with frequent port calls is anticipated to show a larger economic margin for the operators.…”

This paper presents the comprehensive state-of-the-art on the challenges that short sea shipping currently faces across the world. The concept and its relationship with coastal shipping are introduced, followed by a review of the EU policies for short sea shipping and its practical impacts in modal split. A survey of the literature on the strong and weak points of this form of transportation is carried out, aimed at explaining the difficulties in achieving relevant modal shifts from road to sea. The experience with short sea shipping across the world is described and discussed, providing a global perspective. The paper then discusses the main challenges and opportunities in this field, namely decarbonisation, autonomous navigation, and digitalization. Conclusions are drawn on the possible impact of these game changing developments in this segment of the shipping industry.

“…Various methods have been proposed in the past to estimate the cost of building a conventional ship (Caprace, 2009). Based on these methods, MUNIN (2015) and Dantas et al (2023) have estimated costs. Based on the above, this study has determined that the cost of transportation by ship is shown in the following Table 5.…”

“…These studies show that autonomous vessels are economically profitable, and when operated on actual routes, costs can be further reduced through route optimization. Dantas et al (2023) compare the operating costs of a typical Norwegian short-haul vessel with those of a conventional autonomous vessel (TAS), and a new configuration of autonomous vessels (NGAS) with reduced crew living space and other functions made unnecessary by unmanned autonomous vessels and concluded that the reduction of crew facilities on autonomous vessels helps to reduce costs. As for the impact of automation technology on crewing demand, Kretschmann (2017) proposed a system in which instead of crewing autonomous vessels, autonomous vessels are monitored from a remote operations center (ROC).…”

In Japanese coastal shipping, there is a need to introduce automation technology to alleviate the shortage of seafarers, but its introduction has an indirect impact on coastal shipping due to the interaction between transportation demand and freight rates in a market with a variety of stakeholders. Therefore, it is difficult to make decisions about its introduction. This study uses a simulator that mimics the Japanese cargo market to evaluate the impact of the deployment. The results show that the introduction of autonomous vessels, even in the middle of development, may bring benefits, and that remote maneuvering technology with a crew on board may not produce positive impacts.

Sustainable agriculture has become increasingly important in Tunisia due to the drought that has been affecting the country's climate in recent years. This has become a major threat to the economy, making it necessary to explore alternative methods of agriculture that are more sustainable. Moreover, smart hydroponic cultivation based on renewable energies has become increasingly widespread, promoting the quality and efficiency of agricultural production despite weather parameters variations and global warming. This work aims to create a sustainable agriculture system in Tunisia through the design and implementation of a smart photovoltaic (PV) hydroponic greenhouse. The greenhouse will utilize advanced technology to optimize plant growth and reduce water usage, while also incorporating solar panels to generate renewable energy. The end goal is to create a self-sufficient and eco-friendly agricultural system that can provide fresh produce to local communities year-round. In this work, we are interested to the automation of the hydroponic greenhouse (HG)’s thermal conditioning system based on an asynchronous motor pump and powered by a PV generator. In the first stage, we analyzed the mathematical modeling of a stand-alone PV-HG system that consists of a PV generator, a three-phase inverter, an asynchronous motor pump, and a hydroponic system. After that, we developed a Field Oriented Control based on proportional integral (PI) regulators to adjust the rotation speed of the asynchronous motor pump, which aimed to provide the cooling and heating needs of the plant. The simulation results demonstrated the effectiveness of the proposed system . Additionally, we designed and implemented a smart system based on the internet of things (IoT) to enable remote control of internal and external parameters of the HG. This intelligent solution utilizes sensors, microcontrollers, and other devices and ensures the monitoring and the maintaining of the ideal growing conditions for our plants, guaranteeing that they receive the proper amount of temperature, humidity, and lighting. This type of system can be an invaluable tool for maximizing yields and achieving optimal results. With the right approach and attention to detail, we can create a sustainable and efficient growing environment that will help our plants flourish year-round.
