“…Although hull cleanings do not result in mortality of all organisms (Woods et al. ), frequent and gentle cleaning of the hull is likely to prevent fouling (Tribou and Swain ). Although not standard practice yet, the introduction of novel technologies that collect waste during cleaning (Australian Government , 14) could mitigate the risk of introducing invasive species.…”

Merchant vessels are equipped with antifouling systems to prevent accumulation of marine organisms on the hull-a phenomenon known as fouling. In many cases, however, fouling accumulates and in-water hull cleaning is required. Hull cleanings are part of a hull management scheme, and although they are an established practice, their associated environmental and economic trade-offs and conflicts have remained largely unexplored. The purpose of this article is to quantitatively assess both economic and environmental impacts of hull management schemes on the operation of tanker vessels. After identifying induced and avoided costs and environmental impacts from the hull management system, we used both temporally and spatially distributed models to capture the degradation of the antifouling system as well as the global sailing profile of the vessels. Last, we analyzed how each of the modeled impacts varied with the frequency of hull cleanings within the hull management scheme. Our analysis revealed a convex relationship between the frequency of hull cleanings and fuel savings. The higher the frequency of hull cleanings, the less fuel savings can be achieved per cleaning. In terms of costs, from some point on the costs of the service are likely to offset the savings-especially if fuel prices are low. In regards to climate change, avoided emissions due to fuel savings are likely to outweigh the limited impacts from the service itself. Last, while ecosystem impacts from marine, terrestrial, and freshwater eco-toxicity are likely to increase from hull cleanings, they are subject to high uncertainties.

“…To battle this phenomenon, vessels are equipped with antifouling systems. Nevertheless, aggressive fouling might attach on the hull due to high fouling pressure, especially in warm waters (Tribou and Swain ), or when the vessel is sailing slow (Yebra et al. ) (figure a).…”

“…the reduction of environmental impacts is highlighted in the studies by Hearin et al (2015) and Tribou and Swain (2015), who discuss the advantage of weekly grooming the ships' hull panels, providing the release of fouling materials and thus reducing fuel consumption and impacts on the environment…”

Concerns for world peace, freedom, and the future of people and the planet have led to several United Nations Conferences, generating discussions on global sustainable development. These efforts resulted in the 2030 Agenda and its 17 Sustainable Development Goals (SDGs). The proposed Goal 14 reflects the concern for the conservation and sustainable use of oceans, seas, and marine resources. In this context, the research objects of this study are ocean cruise ships and the main dimension surveyed is environmental sustainability. Firstly, the study sought to identify through the convergence of the dimensions of sustainability and cruises the contributions to the cruise industry that promote the SDGs. To this end, we carried out a bibliometric analysis of scientific production on cruise ship environment, narrowing the research focus on environmentally sustainable practices. The second research objective is to examine cruise companies’ strategic inclination to provide information on environmental initiatives to the market. The results show little scientific research focused on the convergence of the two topics studied, environmental sustainability and cruises. Only 12 scientific articles were identified. Regarding the information on environmentally sustainable practices, the findings show that only 22.6% of the 31 cruise companies surveyed provide this information on their corporate websites.

“…Moreover, the viscoelasticity conveyed by the EPS matrix hampers detachment of biofilms by mechanical means Flemming and Wingender 2010;Peterson et al 2015). As a consequence, biofilms cause major problems in many different and widely varying environments, such as on biomaterial implants and devices (Hall-Stoodley and Stoodley 2005;Campoccia et al 2013;Lebeaux et al 2013), ships' hulls (Flemming 2002;Tribou and Swain 2015), water transport pipes (Juhna et al 2007;Rhoads et al 2016) and food packaging materials (Li et al 2009;Nerín et al 2016). Biofilm formation can be described by four distinct phases (Rendueles and Ghigo 2012): (1) transport from an aqueous suspension or air towards a substratum surface (Donlan and Costerton 2002;Nadell et al 2009;Sjollema et al 2011); (2) reversible adhesion to the substratum surface; (3) transition of an adhering organism from a planktonic to a sessile phenotype, producing EPS to cause irreversible adhesion; and (4) growth.…”

Structural changes in S. epidermidis biofilms after transmission between stainless steel surfaces

et al. 2017

Transmission is a main route for bacterial contamination, involving bacterial detachment from a donor and adhesion to receiver surfaces. This work aimed to compare transmission of an extracellular polymeric substance (EPS) producing and a non-EPS producing Staphylococcus epidermidis strain from biofilms on stainless steel. After transmission, donor surfaces remained fully covered with biofilm, indicating transmission through cohesive failure in the biofilm. Counter to the numbers of biofilm bacteria, the donor and receiver biofilm thicknesses did not add up to the pre-transmission donor biofilm thickness, suggesting more compact biofilms after transmission, especially for non-EPS producing staphylococci. Accordingly, staphylococcal density per unit biofilm volume had increased from 0.20 to 0.52 μm -3 for transmission of the non-EPS producing strain under high contact pressure. The EPS producing strain had similar densities before and after transmission (0.17 μm -3 ). This suggests three phases in biofilm transmission: (1) compression, (2) separation and (3) relaxation of biofilm structure to its pre-transmission density in EPS-rich biofilms.
