(eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 1–4. Coconut Creek (Florida), ISSN 0749-0208.

With the support of the Chinese government, the marine area of Macau has been further defined and enlarged, resulting in the rich and premium coast resources. Correspondingly, the Macau government should not only attach crucial importance to the coast resources, but also promote the ecological protection and exploit tourism. Based on the features of Macau's coast resources, the authors of this essay propose that in order to protect the coast resources and ecological environment successfully, the Macau government should create the landscape ecology texture between city and coast, keep full control of pollution sources as well as perfect integrated monitoring system, conduct research on the ecological protection of natural reserves and wetland park, and enhance the education of environment conservation. It is suggested that based on ecological protection and in order to make full use of the opportunity to change Macau into ‘the center of tourism and entertainment in the world’, top-level design is required and the tourism projects and products that integrates gambling industry, shopping, and cultural heritage should be created. In the meantime, the government, enterprises and relevant organizations should launch more projects and programs of leisure vacations and study travels, develop its tourism by cooperating fully with Hong Kong and other cities around Macau. In the future, the ‘win-win’ goal of protecting and exploiting coast resources could be achieved.

Yang, Q.G.; Ning, J.C.; Yang, Y.F., and Li, Y., 2020. Study on the treatment of cracks in the base course of coastal expressways based on the principle of fracture mechanics. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 29–33. Coconut Creek (Florida), ISSN 0749-0208.

During the construction of a highway in the coastal area of Guangxi, China, longitudinal and transverse cracks appeared in the cement stabilized macadam base. On-site comprehensive analysis shows that the road bed filler has weak expansibility and expands after rainfall, thus causing cracks in the base layer. It is difficult to eradicate the cracks in the base layer by the existing treatment methods for cracks in the base layer, and the further development of cracks will endanger the upper layer of the pavement. Based on the principle of crack propagation and crack resistance, a crack treatment method combining crack resistance, waterproofing and structural function is proposed: A water-impermeable film is set at the top crack surface to block the external water source. The film has sufficient fracture toughness to resist the forward extension of the crack tip and can also strengthen the interface bond to restore the overall performance of the pavement structure. After the implementation of the crack treatment method, the corresponding problems can be effectively solved. This treatment method can be of great reference to the relevant problems of crack treatment.

(eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 34–37. Coconut Creek (Florida), ISSN 0749-0208.

The rapid economic development in coastal areas is inseparable from the support of the power trading system. It also poses increasing demands for the power, which results in obvious peaks and troughs in daily power consumption, and causing distribution pressure and power dissipation of the transmission network. Based on the power trading model in Daya Bay area, this paper explores the peak shift optimization model in this coastal area, and establishes a new power trading model to eliminate the impact of power grid monopoly on electricity prices. The results show that the orderly power use in the bilateral trading model can effectively alleviate peak problems in the power trading system; pricing of power system cannot use market bidding, and it must be conducive to the development of high-voltage or ultra-high-voltage power, and also optimized investment by grid companies. The research findings provide a theoretical basis for the realization of power trading between supply and marketing parties.

(eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 43–46. Coconut Creek (Florida), ISSN 0749-0208.

Focusing on the distribution characteristics of marine acoustics caused by high-speed railway channel tunnels, a high-speed railway channel tunnel-ocean bed-ocean fluid-solid coupling dynamic model is established based on the finite element method and fluid-solid coupling theory. By applying the wheel-rail interaction forces which is calculated with the wheel-rail coupling dynamics model as the excitation, the distribution characteristics of the ocean sound pressure has been studied. The spatial propagation law of marine acoustics has been illustrated. Results show that when the train is running at 250km/h, the maximum vibration of the surface of the ocean bed does not appear directly above the tunnel, but on the path that is transmitted upward by 45° on both sides of the tunnel. The maximum underwater sound level is about 136.2∼143.9dB, and the dominant frequency is mainly concentrated in the range below 200Hz. In the vertical direction, the sound level decreases by 3.6∼7.6dB within a depth of 20m. In the horizontal direction, the variation of the sound level at the same sea level is within 2dB ranging from 0∼40m.

Tao, L.; Li, R., and Tian, M., 2020. Effects of government subsidies on the economic and social performance of marine enterprises-Taking Chinese listed enterprises as examples. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 71–75. Coconut Creek (Florida), ISSN 0749-0208.

With the extensive exploitation of ocean in the 21st century, the marine industry is receiving more and more attention. Although government subsidies have played an important role in the development of enterprises as a helping hand, there has been still no targeted study on the effects of government subsidies obtained by marine enterprises. Based on 76 listed marine enterprises from 2010 to 2018, the authors tested the effects of government subsidies on the economic and social performance of enterprises using a fixed-effect model, and also explored the role of government subsidies in marine enterprises of different ownerships. The results show that government subsidies can bring resource advantages to marine enterprises and promote their economic performance; however, the effects of government subsidies on social performance is negative due to the existence of agency problem. Moreover, in non-state-owned enterprises, government subsidies have a positive effect on their economic performance and a negative effect on social performance while the relationships are not significant in state-owned enterprises. The research findings provide empirical evidence for the research on government subsidies.

The simulation and test results showed that the state variables of the motor observed by this method were accurate, the maximum error of the transient state rotate speed estimation was only 8%; in terms of astable estimation error, the rotor position signal lag was only 0.04T; when the load torque changed suddenly, the motor ran steadily and responded quickly, showing good robustness and reliability.

Xie, Y.P. and Li, X.H., 2020. Influence of the coupling effect of ocean currents and waves on the durability of pier structure of cross-sea bridges. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 87–90. Coconut Creek (Florida), ISSN 0749-0208.

In the marine environment, under the action of ocean currents and waves, the piers of cross-sea bridges face a series of durability problems such as salt erosion and salt freeze-thaw cycles. The durability of the pier structure directly affects the service life of cross-sea bridges, so the research and test on the durability are of important significance for the design of cross-sea bridges. Based on the coupling effect of ocean currents and waves in the marine environment, this paper explores its influence on the durability of the pier structure of cross-sea bridges. The research results show that the durability analysis includes environmental index calculation, durability index calculation and durability evaluation. The damage of the bridge pier concrete structure is related to the material composition and the deterioration of the macro performance of the microstructure under the action of special environment. The pier concrete of the target cross-sea bridge measured in the laboratory has a salt-freeze resistance greater than F300. This paper provides an important theoretical basis for the research on the safety of marine concrete structures.

(eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 91–94. Coconut Creek (Florida), ISSN 0749-0208.

Welding technology is widely used in the manufacture and production of structural parts of ocean-going ships. The quality of welding is crucial to the safety of ocean-going ships. This paper attempts to study the NDT methods for welding quality in the key parts of ocean-going ships. To this end, it first summarizes several typical defects that are common in key parts of ocean-going ships, and selects the butt welds on the deck as the research objects. Then, the conventional ultrasonic testing (UT), phased array ultrasonic testing (PAUT), and radiographic testing (RT) were used to conduct the NDT testing on the test plates. Finally, a comparative analysis was conducted for the test results of these three methods. The research results show that like the UT and RT methods, the PAUT can detect all defects, and the qualitative results are consistent; except for incompletely fused defects, its other testing results are better than the UT and RT, verifying the feasibility of the PAUT. The research findings enrich the practical research results of the PAUT in ship welding quality inspection, and provide an effective reference for the promotion of this testing method in marine ship welding quality.

(eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 108–111. Coconut Creek (Florida), ISSN 0749-0208.

The carbon labelling system can realize the transparency of carbon emission sources and guide consumers to purchase lower-emission products. This paper attempts to study the pricing strategy of marine products under the carbon labelling system. To this end, it establishes a decentralized decision pricing model and a centralized decision pricing model for marine products with the carbon tax policy and no carbon tax policy respectively. Then, the analysis of examples was conducted to study the carbon emissions of unit product and retail price changes of marine products under the decentralized decision pricing model and centralized pricing decision model with or without the carbon tax policy. The research results show that when the value of k is constant, the retail pricing of unit products increases with the increase of carbon tax; when the carbon tax is constant, the retail pricing and channel profit of unit products decrease as the value of k increases; when the carbon tax rate is constant, the unit product's carbon emissions and channel profit under the decentralized decision model are lower than those under the centralized decision, and the retail price declines faster than the rate of change under the centralized decision; when the carbon tax rate increased gradually, the decline rate in channel profits and carbon emissions per unit of product gradually decreases. The research findings promote the related research on pricing strategies of marine products under the carbon labelling system, and has certain theoretical and practical reference value.

Zhang, H.Z., 2020. Evaluation of foundation stability of port geotechnical engineering projects based on random field theory. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 120–124. Coconut Creek (Florida), ISSN 0749-0208.

With the rapid development of marine trade and maritime transportation industry, the increase of port-based enterprises has promoted the construction and expansion of port projects in China. Since the spatial correlation of the soil mass in ports is quite complex, the traditional foundation stability evaluation methods have great uncertainty. The random field theory considers the autocorrelation coefficient of the soil mass, so this paper applies the reduction function to calculate the stability of the foundation of geotechnical engineering projects in actual ports based on the random field theory, and explores the feasibility of the random field theory in the calculation of foundation stability. The research results show that: taking the portside geotechnical engineering project in the Pearl River Delta as an example, by applying the random field theory and the reduction function to examine the reliability of the ten tests, it can be clearly seen that the reliability index of the foundation stability of the geotechnical engineering project calculated by the reduction function increases significantly. After applying the random field theory, the calculated foundation stability of the actual port geotechnical engineering project is more reliable. The research in this paper provides a theoretical basis for applying random field theory in the reliability calculation of port foundation engineering projects.

Wang, J.T.; Jiang, B.C., and Guo, Y.L., 2020. Prediction of fatigue strength of extra-large container ships based on spectrum analysis. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 146–149. Coconut Creek (Florida), ISSN 0749-0208.

With the rapid development of maritime transportation industry, container ships have quickly become the mainstream ship model due to their advantages of fast shipping speed, high handling efficiency, and low operating costs. At the same time, their large-opening structure has resulted in poor performance in bending strength, torsional strength and other mechanical properties. In order to ensure the structural safety performance of extra-large container ships, it is necessary to conduct an in-depth research on its fatigue damage and strength life. Based on the spectrum analysis, this paper takes the model 8601ETP extra-large container ship as an example, and adopts finite element modeling to obtain distribution range of the alternating stress; it also uses SN curve and linear cumulative damage theory to predict the fatigue damage and strength life of the container ship. The research results show that the fatigue damage of the extra-large container ship at full load is significantly more severe than that at no load; the degree of structural damage at the position of the keyhole is greater than that at the position of the hatch corner, so it is the hotspot for the fatigue damage analysis and strength check of extra-large container ships. This study provides certain theoretical reference and data support for improving the safety performance of large container ships, and it also enriches the theory of fatigue strength evaluation.

Wang, L., 2020. Stability test and regression analysis of EU carbon tax on coastal trade. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 227–230. Coconut Creek (Florida), ISSN 0749-0208.

Things are happening in the context of the implementation of the carbon tax in the European Union. This paper focus on the current situation of Sino-European trade, and is expected to discuss the impact of EU carbon on Sino-Europea trade by qualitative and quantitative analysis. The empirical analysis shows that since the recent introduction of carbon tax in EU countries, carbon tax has been increasing, and carbon tax has been added to commodity prices, which directly leads to an increase in export trade. This conclusion is slightly in conflict with traditional trade theory. Due to the imperfect collection mechanism in the implementation of the carbon tax in the EU, the reduction in trade volume caused by the decrease in export trade volume may be less than the increase in trade volume caused by the increase in prices, thus increasing the volume of export trade.

Yang, J.H. and Wen, C.H., 2020. Competition analysis of internet finance industry in coastal regions based on Panzar-Rosse model. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 235–238. Coconut Creek (Florida), ISSN 0749-0208.

With the rise of Internet finance in coastal regions, its influence on the banking industry has gradually deepened. To a certain extent, it has seized the bank's asset business, liability business and intermediate business. This paper is based on the establishment of Panzar-Rosse model to determine the degree of competition in China's banking market. In recent ten years, China's banking industry is in a state of monopoly competition and the degree of competition is increasing. Internet finance in coastal regions has little influence on the degree of banking competition in its infancy. However, when Internet finance in coastal regions develops to a certain level, it will have a significant positive correlation with the degree of competition of China's banking industry. In the future, we should actively promote the cooperation between banking and Internet finance in coastal regions to optimize the allocation of social and economic resources.

Building structures in offshore areas are extremely susceptible to chloride ion erosion in seawater or marine atmospheric environment, causing problems such as corrosion and swelling of steel rebar, spalling of concrete protective layer, etc., reducing the service life of the structure, and increasing the maintenance and operating costs of the structure. This paper attempts to enhance the design concrete building structures in the marine corrosion zones from the two aspects of durability and service life. To this end, it summarizes the principles of chloride ion erosion of reinforced concrete structures in coastal areas based on existing research, and explores the destruction mechanism of reinforced concrete structures under the action of chloride ions and external loads. Finally, the new method suitable for durability design of reinforced concrete structures in marine corrosion zone was proposed. The study found that the chloride-induced corrosion to the structure in the marine environment can cause the corrosion of the steel bars and accelerate the corrosion rate; a time-varying reliability model of the reinforced concrete structure was proposed; the increase in the thickness of the steel protective layer in the concrete can effectively improve the durability and service life of the structure. The research findings provide a theoretical basis for the durability design of concrete structures in offshore environments or marine corrosion zones.

Song, Q.H. and Wang, D.D., 2020. Neural network ship PID control and simulation based on grey prediction. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 299–303. Coconut Creek (Florida), ISSN 0749-0208.

Traditional PID is difficult to be applied in large inertial system. It is determined by a large number of engineering experiments, which brings great limitations to the practical application of PID; and the traditional PID control algorithm cannot be applied to the load change, so the control results is always not good enough to be used in the precision requirement. In the paper, the grey prediction control and neural network are combined, and a neural network ship PID control strategy based on grey prediction is proposed, since the grey prediction algorithm needs a small amount of data and small computation load. The simulation results show that the new ship PID self-tuning algorithm is feasible and effective. It can be used in the change of the target parameters, and has strong anti-interference and reliability.
