Authors: Tang Ying , Liu Chunze , Cao Fengshuai , Shang Jianping 
Published: February 2023

AbstractWhen the double-line water-saving ship locks operate in the mode of filling and emptying mutually, the filling water process of one lock chamber and emptying water process of the other one are carried out at the same time, thus the situation of chambers waiting for each other is inevitable. Besides, the variation of ship navigating speed and safety interval time between two adjacent ships may have a more significant impact on the operation efficiency of the ship lock, which cannot be ignored. Combined with the actual condition of a planned lock on a canal in China, the throughput capacity and operation efficiency of the double-line water-saving ship locks under the mode of filling and emptying mutually are studied. A coupled operation simulation model of double-line locks is established, in which the mode of filling and emptying water mutually or independently is adopted. In the model, the whole operation processes of the locks are simulated. The simulation results show that the throughput capacity of the planned ship lock is reduced by 5.6%–7.8%, and the average lockage time is increased by about 10.8%, when comparing the mode of filling and emptying water mutually with independently. Besides, using average value of speed and safety interval time of ships is acceptable when doing research on the throughput capacity and operation efficiency of ship locks. The achievements can provide technical support for the analysis of the throughput capacity and operation efficiency of the water-saving ship lock.

AbstractThe Nord-Pas-de-Calais Division of Voies navigables de France (VNF), the French Waterways authority, is preparing a master plan for the development of turning basins for its ECMT class V network. In this frame, IMDC has been asked to carry out a comparative analysis (benchmark) of the different designs of turning basins in France and elsewhere in the world and to propose design criteria adapted for future developments (for ships of 110 m and 135 m) on the Nord-Pas-de-Calais network. The first part of the study consisted in a desktop review of available national and international guidelines or recommendations on the subject of turning basins design. This helped building a better understanding of the needs in terms of geometry for safe and/or comfortable turning maneuvers. Technical studies of built or projected turning basins on the Nord-Pas-de-Calais network were also analyzed to refine the knowledge on local conditions. Based on the findings of the desktop analysis, interviews of European waterways authorities, international experts and skippers were carried out to further improve the understanding of the problem, both from the infrastructure side as well as from the users’ side. On top of geometry concerns, the interviews tackled hydrometeorological constraints, operational and environmental aspects, auxiliary equipment, etc. From this, a draft technical reference system was proposed for future turning basins on the Nord-Pas-de-Calais network. It proposes two options, depending on whether the basin is located on two banks or on one bank only, and aims at offering each option in two safety and ease levels: a comfort level version, on which the turn must always be relatively easy, and a safety level version, on which the turn must always be possible, but with less ease. The designs were then tested using real time navigation simulations. Optimizations of some of the designs were also proposed to adapt to severe hydro-meteorological conditions. Finally, a decision tree has been developed to facilitate the selection of a design solution according to the local characteristics of the projected basin location on the network. This tool allows the selection of the geometry allowing the easiest turn possible according to the available space and the hydrometeorological conditions present on the envisaged site.

AbstractThe Authors developed a damage assessment system for mooring facilities. This system uses information on seismic motion observed by strong motion seismographs when an earthquake occurs in order to determine whether or not mooring facilities can be used based on the degree of damage suffered. The system creates maps estimating damage based on the results. Two methods are available for determining usability—immediate diagnoses and detailed diagnoses—and all calculations are performed automatically, from the acquisition of the seismic motion information to the determination of usability. The resulting maps estimating damage can be used to select surveyed facilities for on-site damage assessments, making this system an effective tool for supporting initial response systems after a disaster strikes.

Published: February 2023

AbstractThe layout of the navigable junction on the curved river was relatively difficult. The combination of the curved flow and the oblique flow would increase lateral flow velocity in the entrance area, which affected the navigable safety of the ship. There was a bend in the entrance area of the Zhaoxian Junction downstream and a large area of flood plain on the right bank of the downstream channel, which contributed to hardly meet the navigation requirements due to flow coming straight towards waterway affected by flood plain squeezed and river bend. In this paper, normality hydraulic model with 1/80 scale was employed to experimentally optimize the influence of different river regulation measures on navigable flow conditions considering the characteristics of river bend and another situation. The effective river regulation measures were proposed by moving sluice to the left, dredging flood plain on the right bank of sluice downstream and adjusting the operation mode of sluice gate. It was verified that dredging the downstream flood plain to 65 m elevation combined with the operation of left sluice can meet navigable flow conditions requirements. The research results could be used as a reference for relevant junction projects.

AbstractThe submerged dam is one of the commonly used schemes for the prevention and treatment of the pit-type collapse, which is often used in the pit-type collapse emergency treatment in Anhui and Jiangsu sections of the Yangtze River and has achieved good silt-promoting effects. However, the height of submerged dam lacks theoretical and experimental basis in the design and has been determined by experience in the past. Through the physical model of the pit-type collapse of Guizhou Village in the Yangzhong Reach, five different heights of the submerged dam were tested, and the flow velocity, flow direction and surface flow pattern of 12 points in the pond were measured. The test results show that the surface velocity of the inner surface of the submerged dam in the lower part of the pond increases due to the influence of the submerged dam, while the velocity of the bottom layer decreases, and the velocity of the inner side of the upper part mainly decreases; the average velocity in the pond decreases with the increase of the height of the submerged dam and there is a linear relationship between the two; considering that the engineering volume of the submerged dam has a square relationship with the height of the submerged dam, it is believed that the submerged dam should not be too high as long as it meet the sedimentation in the pond.

Published: February 2023

AbstractCompared with sea-going ships, inland vessels mostly sail in restricted waters, which may cause resistance and ship motions to change greatly. To ensure the safety of navigation, it is of great importance to study the hydrodynamic performance of inland vessels navigating in restricted waters. A 64 Twenty-feet Equivalent Unit (TEU) container vessel is numerically simulated at different speeds and water depth draft ratios (water depth/draft = 2, 2.5, 3, 4, 5, 16). The numerical methods are firstly verified and then applied to systematic simulations. The resistance components, ship motions, and details of flow fields are calculated and analyzed. Generally, the total, frictional and residual resistance coefficients increase with a decrease of water depth as expected. However, at relatively low speeds (Fr = 0.1129 and 0.1135) of h/T = 2, 2.5, 3, the resistance components change conversely that they decrease as the water depth gets shallower. This special phenomenon may be caused by the design of the ship hull or the use of the turbulence model that may not be appropriate. The residual resistance has the same trend as the total resistance and the lines are nearly parallel, which shows that the residual resistance is dominant in the component of total resistance. The ship squat phenomenon happens but is not severe in the shallowest condition (h/T = 2). With the water depth decreasing, the wave amplitude becomes larger and the wave crests near the ship bow and stern also increase, while the troughs change slightly at different water depths.

Published: February 2023

AbstractThe development and implementation of the River Information Services (RIS) concept started in the end 1990s with various research projects followed by national or regional implementation projects in the first decade of this century. The resulting national RIS systems haven’t been able to exploit the full potential of RIS when it comes to cross-border data exchange and interoperability. To overcome these gaps the concept of RIS Corridor Management was established aiming at linking the fragmented services together on a corridor to supply RIS along the complete route or network. The concept of RIS Corridor Management was taken up by the CEF (Connecting Europe Facility Programme) co-funded multi-beneficiary project RIS COMEX (www.riscomex.eu) with the goal to implement harmonized RIS services on European level. Within the RIS COMEX project the consortium of 13 countries realized a common and centralized single access point to Inland Waterway Information, the European River Information Services (EuRIS) System. EuRIS acts as European RIS platform fulfilling a great variety of information needs of inland waterway stakeholders like skippers, vessel and infrastructure operators, logistics and authorities. The system gathers relevant RIS information from the national systems in order to provide optimized fairway-, infrastructure- and traffic-related services in a single point of access for the users enabling reliable route- and voyage planning and sharing as well as traffic- and transport management on pan-European level. EuRIS provides access to its services via a user-friendly Graphical User Interface (GUI) or machine-readable Open Application Programming Interfaces (API).In order to guarantee sustainable operation of EuRIS a legal, organizational and financial framework has been setup by the partners. The core aspects concern the joint governance of the system operation as well as the legal basis for RIS data exchange and usage. The full operation and further development of EuRIS is a major milestone in the sector enhancing attractiveness and competitiveness of Inland Waterway Transport in Europe and setting the basis for connectivity to other transport modes and synchro modal logistic operations.

Published: February 2023

AbstractOwing to the high capacity, low costs, and environment-friendly characteristics, shipping has an important role in the sustainable development of the economy, society, and environment. However, with the development of the water transportation economy, the capacity of many navigation locks, such as the Three Gorges ship lock and the Beijing-Hangzhou Canal ship lock, has been hard to meet the increasing demand for passing through the locks. Thus, they have become the “bottleneck” limiting the navigation of the waterways. In the background of the vigorous development of intelligent transportation, the Intelligent Locks has been promoted through extensive research of the Intelligent Locks model, exclusive technology, and intelligent equipment, which is of great significance to improve the efficiency of vessels passing through the locks and enhance the function of waterways. This review starts from the current situation of the research on Intelligent Locks. We summarize the focus of the research on Intelligent Locks and the main tasks of Intelligent Locks. Moreover, the contents of Intelligent Locks are also introduced, such as the network communication platform, intelligent ship identification, positioning system, safety detection system, an intelligent guidance system for shipping, etc. Finally, we conclude that it is the informatization and intelligence that can improve the navigation ability and the management level of ship locks. At the same time, compared with the huge capital demand and the long-period construction of new ship locks, it will have obvious advantages of capital and time by attaching great importance to the automation, informatization, intelligent constructions, and applications of new technologies of existing ship locks.

Study on Advanced Water Level Simulation Method for Inland Waterway Transport Based on the Extended Manning Formula
Authors: Zhou Junwei , Ma Dianguang , Duan Yu , Ji Chao 
Published: February 2023

AbstractThe water level is a critical hydraulic parameter for inland ship safe navigation, as well as an important variable in inland waterway transport minoring and assistant systems. As a basic and traditional method, the one-dimensional (1D) hydrodynamic model is adapted to simulate river sections/waterway segments to obtain water levels numerically. However, the friction factor, i.e., Manning’s coefficient n, is a sensitive parameter for the traditional 1D hydrodynamic model. Its calibration or identification is not only very time-consuming but also unpractical. Due to its sensitivity to the simulation results, usually, one identified parameter cannot be adopted into other flow scenarios. It has been concluded that the unfitness of the traditional empirical quasi-steady friction formulae leads to these consequences/phenomena. Besides finding advanced parameter calibration algorithms and updating friction parameters dynamically, employing a true unsteady friction formula to replace the quasi-steady friction formula is a thorough solution to the problem. In this study, we introduced a newly proposed 1D unsteady friction formula to the momentum equation of the Saint-Venant Equations, thus a modified 1D hydrodynamic model was developed. To validate its capability in simulating water levels, the modified model was adopted into the Xia-la-xian – La-he-lian section of Daying River; and compared with the traditional model with the Manning formula. Results showed that the modified hydrodynamic model performs better in both water level and cross-sectional average velocity simulation. The research results can be used to support the construction of intelligent water level warning systems, intelligent shipping, and digital waterway transportation platforms.

Field Observation and Experimental Study on the Interaction Between Ship Waves And Vertical Wave Dissipation Revetment
Authors: Ju Liehong , Huang Jingxin , Pan Junning 
Published: February 2023

AbstractWith China’s economic development, many inland waterways adopt vertical revetment structure to save land resources, but this structure is not conducive to wave attenuation. According to the measurement results of the ship wave data of typical ship types in Sunan Canal sailing at different speeds collected in field observation, the maximum wave height in front of the vertical revetment wall was less than 1.0 m under normal navigation conditions, while the navigation administration boats can form a wave height of nearly 1.8 m in front of the vertical revetment wall at the maximum speed. In channels with heavy freight and fast ship speed, the ship waves formed by ships, superposed with the reflected waves by vertical impervious revetment, would result in severe water surface fluctuation, affecting the safety of ship navigation and the stability of revetment structure. Based on the regulation project of Sunan Canal, this paper put forward two types of vertical wave dissipation revetment, namely round-hole caisson structure and grid-type structure. And their wave dissipation effects are compared and optimized through 2-D wave test. Finally, the 3-D physical model tests of ship wave and revetment were carried out, and the effects of reducing ship wave height of round-hole caisson structure and grid structure are compared. The results show that these two vertical wave dissipation structures can reduce the maximum ship wave height in front of the revetment wall by about 20–25%. The relevant research results of this paper can serve as a reference for similar projects.
