Trauma and Distress on a Cruise during the COVID-19 Pandemic: A Qualitative Study with Italian and French Tourists

The COVID-19 pandemic has drastically changed our daily lives. One of the sectors most affected was tourism and travel – and, more specifically, cruises, given the prolonged time passengers spend with others within the small spaces of the cruise ship. While finding well-organised entertainment opportunities on cruises is possible, emergency conditions may cause panic. On such occasions, reactions can be highly stressful or even traumatic. This research explores the events and emotions experienced by passengers during a cruise ship quarantined for COVID-19. The empirical materials consist of interviews with 15 passengers. The analyses show four thematic areas: fear of contagion, feelings of discrimination, cooperation between passengers and relationship with the crew. The problems during a cruise ship quarantine presented by the passengers in this study reveal the need for psychological preparation for the crew and security personnel. Finally, we suggest that telemedicine and telepsychology are key elements to improve the efficiency of behavioral control on cruise ships and to mitigate the COVID-19 effects on tourists' well-being during a quarantine. © 2023 by the author.

Optimal selection of cruise ship waste disposal ports

As cruise ships call at many ports and passengers come from all over the world, it is very easy to carry viruses on cruise ships. Under the control of the epidemic situation on board, the solid waste generated by them should be scientifically treated to prevent the spread of infectious diseases such as COVID-19 pneumonia. Therefore, Reasonable selection of waste disposal ports and formulation of unloading plans are directly related to the resumption of cruise operations. This study considers the cost and risk of waste disposal, uses robust optimization to deal with waste volume, increases the scenarios of port service interruption due to epidemics and other reasons, and proposes a variety of emergency strategies. Finally, the relevant strategies are selected according to the decision-maker's preference for cost and risk;By solving the relevant examples, the optimal choice of the cruise ship waste disposal port under the epidemic situation is given, which verifies the validity and feasibility of the model. The research helps to improve the management of cruise waste during the post-epidemic period, and has practical value and guiding significance for the normal operation and development of the global cruise market. © 2023 SPIE.

Sustainable Cruise Tourism: Systematic Literature Review and Future Research Areas

The cruise shipping industry has existed for centuries. However, sustainability is a relatively new trend that could make a big difference and someday impact the industry. A growing body of research on sustainable cruise tourism includes studying changes among industry stakeholders, internal and external processes, and more. However, until now, there have been no comprehensive and systematic reviews of the academic literature on this topic and proposals for future research areas. The sample for our research consists of 56 articles structured into the following themes and subthemes: (1) corporate social responsibility (public interaction and emissions management);(2) territory management (collaboration with stakeholders and infrastructure development);(3) training in sustainable behavior (passengers, ship personnel, and other stakeholders). These themes fully explore the various use cases for sustainable cruises, forming a conceptual framework for understanding trends for the industry's sustainable development. We direct the attention of other researchers to the following areas for further research: GHG emissions of cruising;biodiversity impacts;quantitative understanding of the target audience and their participation in sustainability financing;in-depth understanding of the reasons for cooperation between stakeholders;identifying the true motivation for participation in sustainable development;the long-term trends;and how the shipping industry is adapting to the effects of the COVID-19 pandemic.

Effects of COVID-19 on passenger shipping activities and emissions: empirical analysis of passenger ships in Danish waters

This paper focuses on the analysis of the COVID-19 effects on passenger shipping in Danish waters as an example and aims to analyse the differences in passenger vessel activities and emissions before and after the COVID-19 outbreak. Two sets of Automatic Identification System (AIS) data for the passenger ships sailing in Danish waters associated with the whole year respectively for 2020 and 2019 are used for a comprehensive evaluation of the passenger shipping activities in the region by means of the analysis of variance and bottom-up emission models. A comparison of those results based on the two datasets shows that the COVID-19 pandemic has a major impact on cruise ships, with a significant reduction in the number of ships, average speed, and average draught. In contrast, the pandemic has a smaller impact on ferry-pax only and ferry-ro pax vessels. The effects can also be seen from the fact that, after the COVID-19 outbreak, SOx emissions from cruise ships, ferry-pax only and ferry-ro pax vessels were reduced by 50.71%, 0.51% and 0.82%, respectively. This investigation provides an important reference for policy makers in the marine environment sector.

Tourist Behavior in the Cruise Industry Post-COVID-19: An Examination of Service Quality, Corporate Image, and Intentions to Pay and Revisit

The COVID-19 outbreak has had detrimental consequences on the cruise industry due to the suspension of commercial cruise trips, and these effects remain apparent in Saudi Arabia. The offered service quality (SQ) in the post-COVID-19 era seems to be a critical element for improving customer experiences and satisfaction, enhancing destination attractiveness, increasing revenue, and maintaining repeat business. The current study aimed to assess the impact of service quality on tourists' satisfaction and corporate image as well as the intention to pay for cruise trips and revisit the destination among 315 tourists in Saudi Arabia. Service quality was measured using five subscales of the SERVQUAL scale, including reliability, tangibles, responsiveness, assurance, and empathy. Tourists' satisfaction was significantly influenced by four domains of SQ, whereas the intention to pay more, intention to revisit the destination, and corporate image were significantly predicted by ≤3 domains of SQ. The study's findings can help the cruise industry to improve its offerings and create more personalized and engaging experiences that meet the changing needs of customers in the recovery period after the COVID-19 outbreak.

Can ship travel contain COVID-19 outbreak after re-opening: a Bayesian meta-analysis.

Large gatherings of people on cruise ships and warships are often at high risk of COVID-19 infections. To assess the transmissibility of SARS-CoV-2 on warships and cruise ships and to quantify the effectiveness of the containment measures, the transmission coefficient (ß), basic reproductive number (R0), and time to deploy containment measures were estimated by the Bayesian Susceptible-Exposed-Infected-Recovered model. A meta-analysis was conducted to predict vaccine protection with or without non-pharmaceutical interventions (NPIs). The analysis showed that implementing NPIs during voyages could reduce the transmission coefficients of SARS-CoV-2 by 50%. Two weeks into the voyage of a cruise that begins with 1 infected passenger out of a total of 3,711 passengers, we estimate there would be 45 (95% CI:25-71), 33 (95% CI:20-52), 18 (95% CI:11-26), 9 (95% CI:6-12), 4 (95% CI:3-5), and 2 (95% CI:2-2) final cases under 0%, 10%, 30%, 50%, 70%, and 90% vaccine protection, respectively, without NPIs. The timeliness of strict NPIs along with implementing strict quarantine and isolation measures is imperative to contain COVID-19 cases in cruise ships. The spread of COVID-19 on ships was predicted to be limited in scenarios corresponding to at least 70% protection from prior vaccination, across all passengers and crew.

Effects of media portrayal on perceived cruise risk, image, and intentions.

This research examines how news media portrayal of Covid-19 cases on cruise ships can produce decision biases. Two experiments were conducted in which news stories were varied according to format, base rate, framing and number size. The results demonstrate that prior cruise experience increases travel intentions and cruise image and lowers perceptions of cruise risk. Perceived risk is higher when the number of cases is presented in concrete numbers versus abstract percentages. Negative framing increases perceptions of cruise risk versus positive framing, especially when expressed in small numbers. The results extend beyond Covid-19 by demonstrating that sensationalism in the news media can result in decision biases that over- emphasize negative outcomes and increases risk perceptions in the minds of consumers. The findings suggest travel companies should work together with news media outlets when crisis situations arise to shift away from sensationalism and provide concrete information that is useful for consumers.

Public sentiment towards cruises and resulting stock performance in 2017–2021

Social and economic impacts of the cruise industry are undeniable within the United States (U.S.). Online media about cruising was quantified in terms of volume and net sentiment, then analyzed alongside stock market performance of cruise companies. Daily net sentiment was positively correlated with daily stock closing prices for the three major operators studied (NCLH, RCL, CCL). Further analysis reveals that online media net sentiment had a positive effect on daily closing prices;an increase of 1 point in the sentiment score led to a $0.07, $0.23, and $0.08 increase in the daily closing price of NCLH, RCL, and CCL, respectively. In addition, imposing a no sail order led to negative impacts with the greatest against RCL. Finally, a variable for the COVID effect on these firms revealed differing magnitudes of effect and directionality to each of the firms.

187 - Cruise Ship Infectious Disease Outbreak

This chapter examines infectious disease outbreak on a cruise ship, including the outbreaks and handling of 2020 Sars-CoV-2 on cruise ships early in the COVID-19 pandemic.

An empirical and modelling approach to the evaluation of cruise ships' influence on air quality: The case of La Paz, Mexico.

Maritime activity has diverse environmental consequences impacts in port areas, especially for air quality, and the post-COVID-19 cruise tourism market's potential to recover and grow is causing new environmental concerns in expanding port cities. This research proposes an empirical and modelling approach for the evaluation of cruise ships' influence on air quality concerning NO2 and SO2 in the city of La Paz (Mexico) using indirect measurements. EPA emission factors and the AERMOD modelling system coupled to WRF were used to model dispersions, while street-level mobile monitoring data of air quality from two days of 2018 were used and processed using a radial base function interpolator. The local differential Moran's Index was estimated at the intersection level using both datasets and a co-location clustering analysis was performed to address spatial constancy and to identify the pollution levels. The modelled results showed that cruise ships' impact on air quality had maximum values of 13.66 µg/m3 for NO2 and 15.71 µg/m3 for SO2, while background concentrations of 8.80 for NOx and 0.05 for SOx (µg/m3) were found by analysing the LISA index values for intersections not influenced by port pollution. This paper brings insights to the use of hybrid methodologies as an approach to studying the influence of multiple-source pollutants on air quality in contexts totally devoid of environmental data.

Vessel traffic influences distribution of Aotearoa New Zealand's endemic dolphin (Cephalorhynchus hectori)

Cetacean tourism and vessel traffic have grown considerably around the world in recent decades. At Akaroa Harbor, Aotearoa New Zealand, recreational vessel traffic, dolphin tourism, and cruise ship presence increased substantially between 2008 and 2020. We examined the relationship between vessel traffic parameters and the presence of Hector's dolphins (Cephalorhynchus hectori) during the austral summer 2019–2020, using automated vessel tracking and autonomous passive acoustic monitoring. Data were collected between December 2019 and May 2020, including the entirety of the first COVID‐19 nationwide lockdown. Generalized additive models revealed that increasing levels of motor vessel traffic, the presence of cruise ships, and high levels of dolphin tour vessel traffic resulted in decreases in acoustic detections of dolphins. Our findings suggest that Hector's dolphins at Akaroa Harbor were displaced from core habitat in response to each of these vessel traffic parameters. We recommend that managers use immediately actionable tools to reduce the impacts of vessels on these dolphins.

Building social capital in cruise travel via social network sites

The purpose of this study is to investigate what type of Facebook posts help cruise lines build bridging and bonding social capital. The study applies the Chi-Square Automatic Interaction Detection (CHAID) method to identify which types of posts establish bridging and bonding social capital. The analysis is conducted on an international cruise line's official Facebook posts posted between 1 January 2018 and 1 January 2020 before the Covid-19 pandemic. The results highlight that media type, embedding passenger motivation, and a ship image help establish both bridging and bonding social capital, while content type helps establish bridging social capital. The paper is original because it helps understand how cruise lines can improve bonding and bridging social capital via social media. The paper also enhances understanding of social capital theory in the travel industry by investigating the relationship between Facebook post types and social capital in cruise shipping.

Soil Liquefaction Remediation of the Port of San Diego's B Street Pier Facility Using Deep Soil Mixing

The Port of San Diego's B Street Pier facility (Pier) is the busiest cruise terminal in the City of San Diego with over a hundred ship calls annually (pre-COVID). The Pier is an approximately 9.4-acre bulkhead faced mole extending about 1,000 ft into San Diego Bay and approximately 400 ft wide. On the three offshore sides of the bulkheaded mole are marginal pile supported wharfs constructed in 1923. The upland side of the mole is a concrete gravity seawall constructed in 1900. The mole soils consist of hydraulically placed dredge spoils and are susceptible to liquefaction.The existing Pier containment walls are deemed inadequate for seismic loading, mainly due to the presence of liquefiable materials both in front of and behind the existing containment wall. A solution consisting of an improved Deep Soil Mixing (DSM) zone coupled with the installation of a new steel sheet bulkhead was selected to retrofit and upgrade the Pier to current seismic standards. A key aspect of the design was to minimize loading induced from the wharf onto the existing curtain wall during an earthquake. The DSM zone is intended to serve a triple purpose, that is to improve shear strength of the soils behind the curtain wall, to mitigate the impact of liquefaction, and to provide sufficient bearing for potential future lightly loaded structures which may be constructed on the Pier. To obtain a cost-effective design and limit the DSM zone extents, the design also needed to limit the seismic load contributions to the DSM from the marginal wharves during seismic conditions. A development plan consisting of a multi-phased construction plan was determined to meet the Port's capital improvement needs and budget. Phase I development will install the DSM zone and steel sheet pile bulkhead along the south and west face of the mole. Future work will include wharf pile and deck replacement along with completing curtain wall replacement along the north face of the mole. This paper presents the geotechnical design challenges and considerations associated with the design of the DSM and sheet pile system comprising Phase I of the development plan. Key aspects of the geotechnical design included the selection of appropriate liquefaction resistance of the DSM improved zone, designing for the lateral spread of the slope in front of the curtain wall, assessment of stability and deformation of the proposed sheet pile, and the determination of the seismic earth pressures. © ASCE.

Compulsory insurance for cruise vessels as a preparation for the next pandemic: Law of the sea perspective.

During the COVID-19 pandemic, many port states faced difficulty when cruise vessels with COVID-19 patients tried to dock at their ports. Although they are basically not obliged to accept such vessels under international law, they cannot easily deny access because the refusal would be viewed as a lack of humanitarian consideration. On the other hand, accepting such vessels leads to the risk of exposing their own nationals to COVID-19 and incurring the financial cost of medical treatment for cruise passengers. In fact, in the cases of Diamond Princess, Costa Atlantica, and Zaandam and Rotterdam, the question of who should take on the financial burden for medical costs of crews and passengers on board these vessels was debated. The current international legal framework does not provide any answer to this question, and therefore, a new framework is needed. If the new framework allocates the economic burden to ensure the provision of tests and medical care so that an intolerably heavy burden is not imposed on port states, they will be more welcoming to cruise vessels with infected people. Such allocation could be realized by requesting that carriers provide a compulsory insurance system for medical care in a pandemic.

Cruise tourism in the context of COVID-19: Dilemmas and solutions.

COVID-19 cases on international cruise ships have attracted extensive attention from the international community as well as the world's tourism and shipping industry. This virus highlighted the plight that must be faced by cruise ships in complicated times and situations such as pandemics. The comparative method is adopted to analyze the management measures taken by the "Diamond Princess", "Costa Serena", "Westerdam" and "Grand Princess" cruises in response to the COVID-19 pandemic and then to summarize the common dilemmas faced by these cruise ships, including defects of their internal environment, unclear health-care obligations during an epidemic, weak collaboration between the parties involved and their limited performance, and widespread infodemic and unfavorable public opinion. Given these dilemmas, measures are suggested to deal with the "cruise dilemma", including establishing and defining isolation standards on boards, enhancing the capacity of international organizations, the international community's joint response to the pandemic, promoting cooperation between countries, building an effective mechanism for the broad participation of the whole society, and standardizing the release of information and reasonably guiding public social opinion.

International cruise research advances and hotspots: Based on literature big data

This paper makes a systematic visual analysis of cruise research literature collected in science network database from 1996 to 2019. The results show that: the overall number of published literature on cruise research is growing;North American states, Europe, and Asia are the main regions of cruise research. The evolutionary of theme development of cruise research has three stages, and the current hot topics of cruise research can be summarized as cruise tourism, luxury cruises, cruise passengers, destination ports, environmental and biological conservation, and cruise diseases. Future research in the cruise field are in the areas of cruise supply chain, technology in cruise, children's cruise experience, itinerary design, planning and optimization, brand reputation and luxury cruises, public transportation in destinations, environmental responsibility of passengers and corporate social responsibility, optimization of energy systems, climate change in relation to the cruise industry, the Chinese cruise market and risk management of cruise diseases.

Empirical Analysis of the Cruise Shipping Network in Asia

The cruise shipping market has been growing dynamically in the past two decades. This study presented an empirical analysis of the Asian cruise shipping network (ACSN) in which the nodes are cruise ports and links are cruise routes connecting the ports, using complex network analysis. An analysis of 245 voyages operated by 16 cruise lines between 215 ports in 26 countries found that ports in the ACSN are connected by 704 links. The ACSN is a small-world network with a small average path length and a high clustering coefficient, and its degree distribution follows an exponential function. A small number of ports have high connectivity, and most ports have low connections. Most high-degree ports connect to low-degree ports. The important roles and properties of ports vary depending on centrality measures.

THE CONTRIBUTION OF CRUISE SHIPS TO THE SOUND EMISSION OF A HARBOUR

In recent years, the growth of cruise tourism has often been at the centre of controversy due to the environmental impact, especially for those harbours that, for historical and urban planning reasons, are in close contact with urban areas of particular value or under cultural heritage protection. The deadlock of cruise activities due to the COVID-19 pandemic emergency created the conditions for observing the effects of the substantial disappearance of a specific sound source from the harbours of many cities. This paper presents the evaluation of the contribution of large cruise ships to the overall noise emitted by a specialized cruise harbour and the consequences of their absence on the urban acoustic climate. © International Institute of Acoustics and Vibration (IIAV), 2022.

Cruise revenue management: cross-discipline literature review and development of an integrated cruise revenue management framework

Purpose: This study aims to adopt a holistic approach to understand cruise revenue management (RM) practices that cover ticket and onboard revenues, through a cross-disciplinary literature review and practitioner interviews. An integrated cruise RM framework was developed and served as a blueprint for future cruise studies and practices. Design/methodology/approach: A multi-stage approach was adopted, including a systematic literature review, two-waves of interviews with 26 cruise industry practitioners and the development of a holistic RM framework. Findings: This study clarifies cruise RM functions across product planning, delivery stages and identifies ticket and onboard RM components. These are incorporated into the integrated framework, with weather and itinerary/ route attractiveness as additional considerations. Interviews revealed that there is no difference in the RM cycle before and during the COVID-19 pandemic, although strategies and tactics may vary in response to the market situation. Research limitations/implications: Suggestions are made regarding product and service bundling and ways for ticket and onboard revenue teams to work together to optimize total revenue. Future research directions are also provided under the categories of RM applications and concepts, ticket core activities, onboard core activities and overall issues. Originality/value: To the best of the authors' knowledge, this is the first paper to conduct a cross-disciplinary systematic literature review of cruise RM without imposing publication dates or specific databases and the first to develop an integrated cruise "total” RM framework that includes ticket and onboard revenues. © 2023, Emerald Publishing Limited.
