Maritime Communication

The enhanced automation of the shipping industry has increased the demand of real data exchange. The ship-owners are looking more and more to optimize the operational cost of ship, to monitor remotely the cargo and to ensure a satisfactory level of safety and security, in compliance with the international maritime organization requirements. As per international convention for the safety of life at sea requirements, a conventional ship must carry a global maritime distress safety system, depending on the sea areas where it is operating. We assume that assuring a reliable communication service in the shipping industry is a challenging issue, in an era of internet of things and the need for a ship to be continuously connected to its ecosystem. This connectivity should be with a high data rate transmission. However, the future implementation of autonomous ship beside the existing conventional ship as an alternative for a sustainable maritime industry, requires the implementation of a reliable and cost-effective communication carrier, capable to transfer operational data on live basis from ship-to-ship and from ship-to-shore without interruption with a very low latency. To achieve this goal, we propose in this work, the implementation of 5G network as a maritime communication carrier, using unmanned aerial vehicle base stations, which are placed at optimum positions. This placement results in a maximization of uplink and downlink communication data rate, low latency and efficient optimization of transmission power. These make of 5G a potential maritime communication service carrier, capable to support the safe operation of deep-sea conventional vessels and the future deployment of autonomous ships.

Liquified natural gas (LNG) as a fuel source for shipping is a ready-made solution for the maritime industry. LNG is a clean fuel that meets the current environmental regulations set by the International Maritime Organization (IMO) to lower the sulfur content of marine fuel from 3.5% to 0.5% by January 2020. LNG is also competitive in terms of price and the increasing availability of fueling terminals. This technological readiness promotes the adoption of LNG powered ships, and the demand for such ships is increasing and is projected to increase in the future. LNG fuelled ships (LFS) comply with the tightened emission regulations, and major industry players have predicted that more than 10% of the world fleet will be using gas as a fuel by 2035. The rapid increase in the design and use of LFS has to be carefully monitored to ensure a successful transition. The design of ship and containment systems for LFS is usually carried out using risk-based design processes. Monitoring and advisory solutions are critical to ensure that changes take place in a safe manner. The experience and lessons learned from designing a suitable database framework and data analytics for traditional ship design are presented, and the knowledge transfer and applications for LFS are discussed. Additional critical parameters that are specific to LFS are discussed, and procedures required to ensure quality data collection to provide necessary solutions for the future fleet are presented. The importance of monitoring quality and quantity of the bunkering process with traditional fuel is outlined along with strategies to adopt and promote infrastructure readiness for the increase in LFS use. Data management and big data analysis for decision making is becoming increasingly apparent in many industries, including the shipping industry. Therefore, the inclusion of the systematic design of data acquisition and analytics systems for newly designed LFS is needed. This will accelerate data-driven knowledge generation and design improvements, promote safe and efficient ship operations, and provide a solid foundation for automation. The synergistic blending of solutions from fuel suppliers, engine makers, containment providers, sensor makers, logistics and government will be needed to ensure the global growth and sustainability of LNG fuelled shipping.

Data Rate Transmission

<p>High data rate communication in terrestrial wireless scenarios can be accomplished by setting up Base Stations (BS) on the ground. But applying the similar technique to maritime communication may not be suitable because owing to the geographically constrained nature of the ocean, henceforth, MF/HF modems, extensive-distance transmission characteristics with low data-rate are commonly employed in maritime communiqué. Inmarsat is conservatively used in Maritime satellite communiqué in order to reimburse for low data-rate transmission of MF/HF modems, but its main negative aspect is high cost. To improve the transmission speed along with low price, in general, a network whose architecture is similar to Vehicular Adhoc Network (VANET), that permits peer-to-peer transportation without BS, i.e., ad-hoc network is critical. An ad-hoc network for nautical environment named as Nautical Ad-hoc Network (NANET) was proposed. Multiple access and duplexing schemes are used to implement the nautical network for corresponding NANET scenarios. </p>

This chapter examines the ideological and economic dimensions of the Zionist concept “conquest of the sea” that emerged in the 1920s and 1930s by focusing on the role played by Arnold Bernstein in the emergence of an example of a Jewish shipping industry during the interwar period. In 1895, Theodor Herzl characterized the future Jewish state as the end product of an organized mass migration and endorsed the notion of “conquest of the sea” as a necessary component of this process. The chapter first provides a background on the Palestine Shipping Company founded by Bernstein before discussing the spatial factors that influenced the emergence of a Jewish shipping industry. It suggests that the construction of a Jewish maritime “space” was guided by ideological clashes, economic and political interests, and personal networks.

AbstractEdge offloading, including offloading to edge base stations (BS) via cellular links and to idle mobile users (MUs) via device-to-device (D2D) links, has played a vital role in achieving ultra-low latency characteristics in 5G wireless networks. This paper studies an offloading method of parallel communication and computation to minimize the delay in multi-user systems. Three different scenarios are explored, i.e., full offloading, partial offloading, and D2D-enabled partial offloading. In the full offloading scenario, we find a serving order for the MUs. Then, we jointly optimize the serving order and task segment in the partial offloading scenario. For the D2D-enabled partial offloading scenario, we decompose the problem into two subproblems and then find the sub-optimal solution based on the results of the two subproblems. Finally, the simulation results demonstrate that the offloading method of parallel communication and computing can significantly reduce the system delay, and the D2D-enabled partial offloading can further reduce the latency.

Design And Construction

The design and construction of any marine vessel designed on a computer-assisted design (CAD) system, from a nuclear aircraft carrier to the smallest work boat, requires the interaction of many electronic databases, all of which must be continually updated for the work to proceed. The exchange of this information, especially geometry, in digital format is accomplished using many different tools and techniques. Much has been presented to the marine community about the tools used, such as the Initial Graphics Exchange Specification (IGES) and the Standard for the Exchange of Product Model Data (STEP), and how these tools might be used for exchanges in the future, but little has been presented on how production data exchanges actually occur. At Electric Boat, current submarine programs cannot wait for future data transfer solutions. Design and construction data must be exchanged among various activities, internal and external, with such volume as to make manual reentry of data an unrealistic solution. Because of the complexities associated with the electronic exchange of these data, the General Dynamics (GD) Marine organization of Electric Boat has a dedicated group that both performs production data exchanges and researches and implements new methods of electronic transfer. This paper discusses the rationale for and the formation of the data exchange group at Electric Boat, along with its place within GD Marine. It then presents an overview of the tools used by the group and how production transfers occur, both routine and unique. Notable transfers provide examples of how the group works to solve transfer problems. Importantly, this paper shows how many of the exchange standards developed for the marine industry actually work in production. Special emphasis will be placed on the exchange of solid models in a day-to-day environment. The paper concludes with a look at the future of production data exchanges for Electric Boat and the larger marine industry.

Radio Access

Future-generation radio access networks (RAN) are projected to fulfill the diverse requirements of user equipment (UE) by adopting a heterogeneous network (HetNet) environment. Necessary integration of different radio access technologies (RAT), such as 2G, 3G, 4G, wireless local area network (WLAN), and visible light communication (VLC) is inevitable. Moreover, UEs equipped with diverse requirements will be capable of accessing some or all the RATs. The complex HetNet environment with diverse requirements of UEs will present many challenges. The HetNet is likely to suffer severely from load imbalance among the base stations (BSs) from inheriting the traditional user association scheme such as max-SINR (signal-to-interference-plus-noise ratio)/max-RSSI (received signal strength indicator), unless some sophisticated schemes are invented. In this paper, a novel scheme is devised for a joint-user association for load balancing, where BSs are densely deployed and UEs typically have a certain degree of mobility. Unlike most of the present works, a dynamic network is considered where the position and channel condition of the UEs are not fixed. We develop two complex and distributed association schemes based on probability and d-choices, while carefully considering both loads of the BSs and SINR experienced by the UEs. Numerical results validate the efficiency of the proposed schemes by showing a received data-rate fairness among UEs and an improvement in the UE’s minimum received data rate.
