Analysis on the state of cruise ship industry and cruises in the conditions of the COVID crisis

The cruise ship industry is one of the most affected part of tourism sector worldwide after appearance of the coronavirus. The ban on cruise travel issued by the WHO in March 2020 hits not only to tour operators and cruise ship owners, but also reflected on shipbuilders. The article analyzes the state of cruise industry in the conditions of COVID crise and give some directions for future efforts dealing with recovery and future development of the cruise sector

Factors related to development of cruise shipping industry

In recent decades, there has been a strong growth of the cruise industry, which has managed to develop innovative concepts in terms of safety and security service and to offer attractive vacation to the exotic destinations around the world. Thus, the cruising has gradually become a major part of the tourism sector and has become one of the main economic factors for development of shipping industry. Based on analysis of the global demand on cruising this article defines the factors influencing the development of cruise fleet and leading cruise lines and provide a vision for future efforts in field having in mind also the dynamic changes in current situation

Reflection of expanded Panama Canal to supply chains and port infrastructure in North America

The enhancement of world maritime shipping leads to increasing of the time required for transit passage and impossibility of old locks in Panama Canal to serve the newest vessel’s generation. Many states in east and south-eastern part of the country, as Florida, Georgia, Virginia and South Carolina, are becoming attractive for business. They have made various investments and improvements in regional transport infrastructure to dominate over freight traffic in the region, such as dredging of port entrances and port basins, expansion of container terminals, and improving inland transport connections to the port. The goal of this article is to study how the design and construction of new set of locks on the Panama Canal affects to the global trade and further to the multimodal chains, transport infrastructure and ports along the East American Coast

Application of social management in logistic sector for building of stable and competitive multimodal transport chains

The transport is an important economic sector that contributes to meeting the people needs. The integration of transport processes and the creation of multimodal transport chains is important for improvement on the quality of the transport service and reduces the current costs of the logistic service.The questions, addressed to social management are of growing importance and priority today. Among the leading prerequisites for this are globalization, the role of knowledge, information, cultural dialogue, the growing importance of social interaction factors in world etc. Due to the above considerations, the following paper presents a study of current, debatable issues regarding the modern management concept, named "social management" in the case of the logistics business especially in creating of competitive transport chains

SELECTION OF APPROPRIATE TRANSPORT FORMULAS FOR ESTIMATION OF TRANSPORT AND DEPOSITION RATES AT BABREKA CANAL

Siltation is a significant factor, affecting the efficient operation and maintenance of the irrigation canals which influence the hydraulic behavior of the canals and economic benefits of irrigation. In last 25 years a tendency of silting up at the irrigation canals in Bulgaria is observed due to the following reasons: decreased area under irrigation, fluctuation in supply, non-regime section, ”berming” of the canal, economic, crime and safety situation. The large number of available bed load and permissible velocity formulas and the significant differences between obtained results enforce selection of appropriate sediment transport formulas in each particular case. In this study discharge and velocity approaches are used for estimation of sediment transport and deposition rates at Babreka Canal, Malka Vitska Irrigation Project in Bulgaria. Seven equations for prediction total bed load transport rates and five equations for minimum permissible velocity are compared. The results show substantial differences in performance. Two formulas for total bed load and two formulas for minimum permissible velocity are selected as appropriate for the studied canal

Challenges to contemporary maritime building

Globalization, continuous introduction of modern technologies, computerization of performed working operations and digitization of information exchange are results from commercialization of services offered. The purpose of this article is to provide a vision for future efforts in field of maritime high education and training, in order to improve skills and capabilities of next seafarers generation

EVALUATION OF WATER DELIVERY EFFICIENCY IN IRRIGATION CANAL UNDER EXISTING MANAGEMENT STRATEGY USING HYDRAULIC MODEL

Managing water distribution in irrigation canals aims timely and in needed quantity implementation of supplies of water to irrigated area without excessive spillage i.e. at reduced conveyance loss and adequate water use for irrigation of the crops. This article analyzed existing management practice of water distribution in irrigation canal in view of efficiency. The study was carried out for an existing main irrigation canal. The operational water loss was evaluated by indirect quantitative approach. Hydraulic simulation model of the irrigation canal was created using hydraulic software HEC-RAS. Changes in hydraulic conditions due to existing structures along the canal course were taken into account in the model. The water operational loss was determined by simulation with HEC-RAS model in steady state conditions. The model was used to study the influence of the operating conditions on the size of loss. Results obtained show the influence of the management practice of the water distribution and operation conditions and maintenance of the canal on the magnitude of operational loss
