“…More and more sensors for enhancing the convenience and safety of passengers and crew are being deployed in the ships to collect information such as the hull form of the ship, speed, pressure, temperature, and so on. A number of ship wireless sensor network technologies aimed at increasing the safety of a ship have been developed [1,2]. The replacement of conventional wired links with wireless connections in ship systems presents a number of challenges regarding system reliability and safety.…”

This paper presents a statistical characterization of Ultra-Wideband (UWB) channel for ship cabin environment based on measurements carried out in the frequency-domain and covered the frequency band of 6-9GHz. According to the results of measurement, it is observed that rays arrive in clusters, so we describe the multipath propagation with the classical S-V model. The main purpose is to study multipath propagation behavior, particularly the phenomenon of clustered multipath components. An efficient cluster automatic identification algorithm based on wavelet analysis is employed for clusters identification of the discrete UWB channel impulse responses (CIRs). Then, the statistical characterizations of multi-path components (MPCs) are examined. Finally, simulation results of the proposed statistical model are compared to measured data demonstrating reasonable agreement. The results are helpful to model the UWB propagation channel in such environment.

“…Metallic structure of bulkheads and watertight doors severely decrease the power of received radio signals. Moreover, due to the metallic environments on board ships, propagation effects like the multipath can be a serious cause of received signal degradation [9]. The solution can be the installation of repeater nodes to overcome metal obstacles.…”

“…Similarly, the wireless communication seems to be reasonable application, where either the object is situated in an inaccessible place or where the structure of the cable connections is expensive. Since deploying full-scale wired sensor networks on a ship leads to complexity and high costs, Cho et al proposed a Wireless Sensor Network (WSN) solution [9]. Fundamentals and many interesting information related to this solution namely WSN technology, can be found in [10].…”

This paper is dedicated to some aspects of maritime on-board safety improvement. The contribution of this article is a proposal to extend wireless communication on the ship, supported by examples of solutions that have not previously been used on board. Analyzed aspects concern the measurement and control signal transmission in hostile marine environment. A problem to solve is formulated, how to reduce a negative impact of this environment on effectiveness and reliability of maritime on board communication. The proposed ways for solving a problem under consideration cover recommendations concerning some aspects of ship construction and implementation of wireless sensor network. The main topic faced by the paper is concentrated on case study-based ZigBee as well as WiFi networks implementation in the area of the acquisition of data from sensors and measuring transducers connected to the terminal network. The exemplary implementation of ZigBee network, elaborated in Gdynia Maritime University is related, firstly, to the configuration of a simple wireless measurement and control channel, and secondly, to wireless communication channel supported by autonomously working microprocessor measurement and control system. WiFi networks were also tested in the same area of application. Finally, some concluding remarks are formulated.

“…There are issues with ZigBee application on board ships. In [56], the authors have researched into ZigBee WSNs for shipboard use and have found that there are problems with signal penetration of the ship hull. Signal attenuation due to low power transmission and interference with the existing WLAN and Bluetooth technologies has been found to be a prevailing issue.…”

A B S T R A C TSeagoing vessels are highly complex systems. Major requirements of marine vessels are continuous running time and high production output. As such, these systems require high availability and reliability, and are dependent on preventive maintenance procedures. Development of diverse range of sensors, combined with overall reduction in price, enabled implementation of condition based maintenance in such systems. Large increases in fuel cost, environmental restrictions and further crew reduction are current trend in maritime industry. Considering marine sector emphasis on the reduction of fuel consumption, environmental restrictions, and reduction of crew size, implementation of condition based maintenance is favourable, especially with regard to lost man-hours. However, high initial cost of installation on moving vessels, necessary crew training and additional sensor maintenance inhibits implementation of condition based maintenance. Replacing wired monitoring system with wireless ship-board sensor network would mitigate the above mentioned problems. However, current research of wireless sensor networks is based on terrestrial installation. This paper analyses the application of wireless sensor network technology on board seagoing vessels. Practical engineering solutions, including sensor types, configurations and wireless network topologies have been identified and reviewed.
