The Northern Sea Route (NSR) could become viable in the near future. If this happens, it will radically reduce sailing times and distances on routes from Asia to Northern Europe. However, although much has been written about the feasibility of the NSR, about the issues involved and about the possible opening of the route, the views of key stakeholders from companies who would potentially benefit from the route have been little explored. The purpose of this paper is to complement the existing literature on the feasibility of and issues related to the NSR by presenting and discussing the results from in-depth qualitative interviews with nine key stakeholders based in Shanghai and Taiwan who have extensive research, knowledge and practical experience of NSR.

Based on a grounded theory analysis, a total of nine key stakeholders knowledgeable about NSR and the majority with sailing experience of NSR are interviewed, including one government official, two professors, shipping experts in six liner and one bulk shipping companies.

The authors present interviewees’ thoughts regarding the feasibility of NSR at the current time in terms of practicalities, ships, costs, information and wider issues.

These thoughts show that whilst the potential of NSR is huge in theory, in practice the overall perception of it in terms of current feasibility from a company perspective is one of challenges and unknown issues. Shipping companies can benefit from the authors findings when considering the feasibility of NSR as a shipping route. Ultimately, the picture emerges that without one country, probably Russia, taking the lead on the route, it will remain only a theoretical one.

In-depth interviews with grounded theory are used to investigate current and actual thoughts on NSR. This paper highlights correlations and additions to show a fuller picture of current knowledge and adds views from Shanghai and Taiwan.

The purpose of this paper is to provide a conceptual framework for using citizen science – defined as a data collection method through which non-professionals engage in contributing to authentic scientific inquiry – within the expedition cruise industry to contribute significantly to the collection of environmental data from hard-to-access Arctic areas.

The authors review trends in Arctic expedition cruise tourism and current needs in Arctic research and monitoring, and clarify where the expedition cruise tourism industry could have the most impact by providing data to the scientific community. The authors also compare the regulatory context in the Antarctic to that in the Arctic and discuss how these differences could affect the widespread use of citizen science. At last, the authors describe some general principles for designing citizen science programs to be successful on board, and highlight several existing programs that are being recognized for their contributions to a greater scientific understanding of the Arctic.

The authors find that citizen science data from the expedition cruise industry are underutilized as a tool for monitoring Arctic change. Numerous examples illustrate how citizen science programs on-board expedition ships can successfully collect robust scientific data and contribute to enhancing the knowledge and stewardship capacity of cruise passengers. Inclusion of citizen science data from the expedition cruise industry should be considered a critical part of international Arctic observing networks and systems.

Active participation in Arctic citizen science by tourists on expedition cruise ships has many potential benefits beyond the collection of high quality data, from increasing passengers’ knowledge and understanding of the Arctic while on board, to affecting their attitudes and behaviors after they return home.

The potential for tourism to contribute to Arctic observing systems has been discussed previously in the scientific literature; the authors narrow the focus to citizen science programs in the expedition cruise industry, and provide concrete examples, in the hope that this will streamline acceptance and implementation of these ideas by researchers and tourism practitioners.

This paper focusses on the aftermath of disruptions and the importance of the two largest canals (Suez and Panama), commenting on how during the pandemic the canal fees were lowered. Considering the ongoing efforts to decarbonize shipping, some of the ongoing disruptions will help reach these objectives faster.

Following a literature review of route choice in shipping, and a presentation of significant disruptions in recent years, the author deploys a simplified fuel consumption model and conduct case study analyses to compare different routes environmentally and economically.

The results explain why at times of low fuel prices as in 2020, canals provided discounts to entice ship operators to keep transiting these, instead of opting for longer routes. Considering the ongoing repercussions of the pandemic in supply chains, as well as the potential introduction of market-based measures in shipping, the value of transiting canals will be much higher in the coming years.

The main limitation in this work is that the author used the publicly available information on canal tolls, for the different ship types examined.

The envisioned model is simple, and it can be readily used for any ship and route (port to port) combination available, if ship data are available to researchers.

It is possible that canal tolls will increase, to account for the additional environmental benefits brought to ship operators.

The methodology is simple and transferable, and the author proposes several interesting research questions for follow-up work.

The purpose of this study is to find out the future development of the Panama Canal after opening of the new waterway (third set of locks project), in terms of the change of cargo throughput, further deployment of fleets by the shipping companies and competition for the canal.

The research of this paper is based on an empiric study by collecting the relevant data from annual report of the Panama Canal Authority, publications related to the same field. Graphs pertaining to toll revenue also are made based on statistical data provided by the Panama Canal Authority.

The findings show that the opening of the new waterway of the Panama Canal generates more toll revenue for Panama government by allowing mega-vessels to transit, expediting further economic development of the country largely from behind. At the same time, shipping operators also can enjoy earning more revenue by deploying New Panamax vessels transiting the Canal.

Ingenuity in tabling the users of the Panama Canal by incorporating the logo marks of the shipping companies/implication is drawn through empirical analysis to provide the shipping companies and ports authorities concerned with more understanding toward the very significance of the new waterway expansion of the Panama Canal.

Much literature considers future impacts of the Kra Canal on shipping times and on individual countries. In this paper, the authors consider the maritime business potential of the Kra Canal for companies, ports and countries.

Based on a combination of a review of the extant literature, quantitative data from relevant calculations and qualitative data from semi-structured interviews with experts (n = 20) from four countries in the region, this paper contextualises the business potential of the Kra Canal through a PESTELE (political, economic, social, technological, environmental, legal and ethical) analysis before outlining a more targeted SWOT (strengths weaknesses, opportunities and threats) analysis to consider the potential for maritime business.

The PESTELE analysis reveals that there are a number of challenges related to the construction and possibility of the Kra Canal being built such as its impact on the political balance within the Association of South East Asian Nations (ASEAN) region. The SWOT analysis shows that the potential of the Kra Canal for maritime business is significant, and that the strengths and opportunities of increased route possibilities and reduced sailing times outweigh any weaknesses and threats.

Most studies into the Kra Canal focus on highly specific research targets or provide a particular perspective (e.g. historical). This paper, by drawing on two commonly used analytical frameworks, considers the canal for the first time from a wider context perspective as well as a specifically business one. Recommendations are made for policy makers and maritime businesses on the basis of the results.

The purpose of this paper is to test the performance of the control system developed for the helicopter automatic approach and landing on the moving vessel deck, when different values of backlashes are applied to the four control actuators.

The system consists of automatic control algorithm based on the linear quadratic regulator and the vessel motion prediction algorithm based on autoregressive method with parameters calculated using Burg’s method. Necessary navigation data is provided by on-board inertial navigation system/Global Positioning System. Calculated control commands are executed by four electromechanical actuators. Performance of the mission, which is based on selected procedure of approach and landing of the helicopter on the moving vessel deck, is analyzed taking into account different values of backlashes applied to the actuators.

In this paper, a description of the control system dedicated for automatic approach and landing of the helicopter on the moving vessel deck is shown. Necessary information about helicopter dynamic model, control system and vessel motion model is included. Tests showing influence of actuator backlashes on the mission performance are presented.

The developed control methodology can be adapted for selected helicopter and used in prospective development of an automatic flight control system (AFCS) or in a simulator. The system can be used to define in which conditions helicopter can perform safe and successful automatic approach and landing on a moving vessel deck.

In this paper, an integrated control system is presented; influence of the control actuator backlashes on the mission performance is analyzed.
