Management Measures to Reduce Continuous Underwater Noise from Shipping
- 2023
-
Rapport (refereegranskat)abstract
- Underwater radiated noise (URN) from commercial ships is a significant source of elevated noise levels in the oceans and can have a negative impact on marine wildlife. Noise from commercial shipping places additional stress on the oceans, but is one of the least studied environmental pollutants, and there is an urgent need to reduce the aggregate stress levels. Until recently, reduction of underwater noise has not been prioritised by ship designers, shipowners, or crews. Even within the field of marine management, noise has received limited interest. However, the International Maritime organization (IMO) has adopted global guidelines on URN reduction, which are currently being updated. Within the EU, the Marine Strategy Framework Directive (MSFD 2008/56/EC) Descriptor 11 criteria 11.2, now provides a framework for marine administrators to manage noise by establishing threshold values. Marine management focuses on the total noise load on the marine environment. Management entails several considerations before recommendations can be made. As a first step, interdisciplinary teams need to assess the aggregated noise levels and determine acceptable thresholds based on the local ecosystem, then assess which existing mandates and management tools can be used, and finally assess how effective these mandates have been in improving the environment. These activities must also be managed in a way that is acceptable to various relevant stakeholders, who would need to follow the decisions. The URN from a ship can be affected by the vessel’s design, either during its construction or during upgrades, and balances a trade-off against fuel efficiency. However, the URN can also depend on how the ship is operated. Regulating ship speed is one potential management tool, and its effectiveness needs to be assessed. Other management measures include how shipping lanes are drawn, areas to avoid, financial support, information, etc. This report focuses on possible policy measures that the Swedish authorities could adopt to lower URN by regulating the speed of ships. The report presents an interdisciplinary analysis, using a case study of an area in the southern Kattegat that covered several maritime zones, different national jurisdictions, intensive traffic, and high natural values. An important part of the work was to assess whether existing source models for ship noise could be used for the type of ships that are common in waters around Sweden. In this study, the JOMOPANS-ECHO (J-E) model was used.The J-E model was validated by comparing measurement data from a hydrophone station at Vinga on the Swedish coast that collected data from ships (254 passages) that used the port of Gothenburg. The analysis showed some deviation between the J-E model and measurement data, which could be due to differences in the length and speed of ships in waters around Sweden compared to the ships used in the development of the J-E model. However, this was likely to have negligible impact on the outcome of the case study.Analyses of ship traffic in 2021 showed that 4,511 unique vessels visited the study area at least once. Most ships followed the main routes, but no part of the study area was completely free from ship traffic. About 68% of the ships visited the study area for 1-4 days, while about 32% visited the area more regularly. The most common ship types were General Cargo Ships, Dry Bulk Ships, and Tankers. The ships that on average travelled at highest speeds were RoPax Ships, RoRo Ships, Vehicle Carriers, and Container Ships. The ships were registered in 64 countries. About two percent of the ships were registered in Sweden and about four percent in Denmark.Legal analysis showed that Sweden has the right and the responsibility to take measures to reduce underwater noise from ships to the extent that the noise can be deemed to pollute the marine environment. However, this mainly applies to Sweden’s territorial seas, which cover roughly half the area being studied for this report. In the portion that constitutes Danish territorial sea, Denmark has comparable opportunities for managing URN. In areas that are Swedish or Danish exclusive economic zones (EEZs), the ability to introduce mandatory speed limits is significantly limited. There, the most realistic option would be to request the IMO to establish speed limits, or alternatively to issue a recommendation to navigate at lower speeds, although such guidance could not be enforced on ships that do not voluntarily reduce their speed.It was estimated that lowering the ships' speeds to a hypothetical limit of 11 kn would reduce the average URN levels by 4.4 ± 2 dB, as registered by local receivers in the study area. This speed limit would affect approximately 44% of the ships in the area. A maximum speed of 13 kn would instead reduce the level by 1.9 ± 0.5 dB and would affect 11% of the ships on average. The reduction in noise levels may temporarily be much higher in the immediate vicinity of individual fast ships, and there might be a high degree of variation between different ships.The study and report make it clear that it is a complex task to assess the feasibility and benefit of introducing a specific marine management tool, in this case an enforceable local speed limit. But it is also clear that there are reliable methods to make the preliminary assessments, and that it requires interdisciplinary analyses and competence.

Säkrare transporter av farligt gods – Ett förslag till nollvision
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Säkra transporter av farligt gods på väg och järnväg är en synnerligen komplex aktivitet i skärningen mellan juridik, teknologi, logistik, ekonomi, organisation, och individ. Graden av komplexitet ökar med frågor om styrning, säkerhet, miljöhänsyn, hållbarhet, fysisk planering, och konkurrens. Planering av forskningsarbetet, datainsamling och analys har skett i en tvärvetenskaplig kontext där forskare från juridik, logistik, informatik, och miljövetenskap deltagit. Exempel på frågeställningar som har studerats inom ramen för projektet är säkerhetsrådgivarens roll och funktion, problem och brister i transportkedjan, vilka aktörer som är involverade i transportkedjan och hur trafikpolisen utför sina operativa kontroller av transport av farligt gods. Vidare har projektet resulterat i nya forskningsfrågor att undersöka och analysera i framtiden. Det handlar bl.a. om hur våra urbana miljöer ska kunna utvecklas och möta utmaningar kopplade till transport av farligt gods. Detta presenteras närmare i ”case Älvstaden”. Studierna av regelverken som styr transporter av farligt gods, logistiska begrepp och principer som bidrar till ökad precision avseende en nomenklatur, och transportkedjan som informationsmiljö, utgör exempel som är mer teoretiskt grundade i de olika disciplinerna. På en övergripande nivå är detta ett viktigt komplement till de empiriska avsnitten och en förutsättning för att kunna tydliggöra komplexiteten i projektet. Denna kortare rapport återger viktiga resultat i projektet, och den utgör sammanfattning av en längre slutrapport som publiceras hos MSB hösten 2021. I den längre rapporten, Säkrare transporter av farligt gods genom transparent informationshantering och samverkan, återfinns nulägesbeskrivningar med tillhörande publikationer som utgör ett mer samlat resultat av projektmedlemmarnas ansträngningar. För att nå målbilden om säkra transporter samlas de viktigaste resultaten från projektet i en lista med åtgärdsförslag. Dessa förslag omfattar områden som vi anser har särskilt god potential för utveckling och ett urval av sådana åtgärdsförslag finns med i denna slutrapport.

Säkrare transporter av farligt gods genom transparent informationshantering och samverkan : Safer transport of dangerous goods by information management and collaboration
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Farligt gods kan definieras som de ämnen och föremål som kan orsaka skada på människor, miljö och egendom om de inte hanteras på rätt sätt under transport. I förhållande till den mängd farligt gods som transporteras i Sverige inträffar förhållandevis få allvarliga olyckor. Däremot inträffar en incident med farligt gods nästan varannan dag i Sverige. Syftet med projektet är att bidra till att transporter av farligt gods kan genomföras på ett så säkert, men ändå ändamålsenligt, sätt som möjligt. Utgångspunkten är att identifiera styrkor och svagheter längs transportkedjan för att olyckor med transport av farligt gods ska kunna undvikas. Inom projektet har information och kunskap samlats in direkt från privata och offentliga aktörer i transportkedjan eller med koppling till kedjan. Detta har skett genom intervjuer, möten, fältstudier, studiebesök, workshops och konferenser samt indirekt genom bland annat litteraturgenomgångar, studier av media och regelanalyser med stöd av juridisk metod. Undersökningarna har, förutom denna rapport, resulterat i ett flertal publikationer, såsom exempelvis vetenskapliga artiklar, böcker och konferensbidrag samt olika typer av presentationer. Den kanske viktigaste kunskapsspridningen har dock skett genom en nära dialog med avnämare och genom ett ömsesidigt lärande. I denna rapport återges viktiga resultat från projektet. I kap. 2-7 återfinns en nulägesbeskrivning med tillhörande publikationer som utgör ett samlat resultat av undersökningarna som utförts under projektets gång. Nulägesbeskrivningen omfattar en beskrivning och analys av följande: • transportkedjan vid transport av farligt gods (kap. 2) • transportkedjan som en informationsmiljö (kap. 3) • regelverken rörande transport av farligt gods (kap. 4) • säkerhetsrådgivare för transport av farligt gods (kap. 5) • tillsyn för säkrare transporter av farligt gods (kap. 6) • problem och brister i transportkedjan (kap. 7) Kapitlen utgör ett underlag för att kunna formulera de åtgärdsförslag som presenteras i kap. 8. I det avslutande kap. 9 ges en utblick mot framtidens utmaningar. Det ska poängteras att det inte finns ett enda specifikt problem inom området för transport av farligt gods, utan det föreligger flera olika problem. Dessa problem kan enskilt eller i samverkan med varandra leda till risker som påverkar säkerheten negativt vid transport av farligt gods. Det är därför viktigt att riskerna minimeras, till fördel för ökad säkerhet. Det finns dock inte en enda lösning eftersom området är komplext med många aktörer och omfattande och detaljerade regelverk. Vi presenterar åtta åtgärdsområden som vi menar är särskilt viktiga och introducerar en målbild som består av en nollvision för olyckor, incidenter och tillbud vid transport av farligt gods. Nollvisionen preciseras i kap. 8. De aktuella åtgärdsområdena presenteras i kap. 8 och utgörs av: • Ökad medvetenhet • Ändamålsenliga regelverk • Rätt kompetens • Stärkt säkerhetsrådgivarroll • Informationstillgång • IT-system med samverkansförmåga • Synliggörande av dolt farligt gods • Effektiv tillsyn och kännbara konsekvenser Åtgärdsområdena innehåller en tillhörande problematisering för att sätta området i sitt sammanhang. Varje åtgärdsområde omfattar även en delvision som visar på vad just det området kan bidra med för att nå nollvisionen som framförs i projektet. Vidare ges exempel på konkreta åtgärdsförslag som har kunnat identifieras genom forskningen i projektet. Dessa åtgärdsförslag har särskilt god potential att kunna bidra till säkrare transporter av farligt gods.

Reducing undeclared and misdeclared dangerous goods to improve maritime transport safety
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Transport of dangerous goods creates substantial utility to society, but carries a risk to the environment, health and safety. Some of the accidents and incidents occurring during dangerous goods transport can be attributed to poor practices, such as misdeclaration or failure to declare the goods. This pre-study aims to investigate the problem of undeclared and misdeclared dangerous goods transport on container, RoRo and RoPax vessels and to investigate the circumstances and causes that lead to incorrect declaration. For this purpose, this research carried out a literature review and conducted several interviews with main stakeholders in Sweden such as port authorities, port terminals, shipping companies, insurance companies and public institutions. Main results suggest that the existence of different regulations (land transport and sea transport for dangerous goods), can be a risk for managing these goods. Furthermore, it is important to enhance coordination between different actors and increase digitalization to control information flows. This pre-study is coordinated with the longer and larger project Transparent information management and collaboration for improved reliability during transportation of dangerous goods funded by the Swedish Civil Contingencies Agency (MSB).

Regulatory aspects of Electric Vehicles and Fire in Maritime RoRo/RoPax Transports : A pre-study initiated by Lighthouse.
- 2024
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This pre-study research paper explores the regulatory aspects of electric vehicles in maritime RoRo/RoPax transports, focusing on the risks and effects of electric vehicle fires on board ships. The study highlights concern about the increased risk of transporting electric vehicles and examines various incidents of fires in electric vehicles. The paper discusses the regulatory initiatives taken on different levels and identifies different perceptions of risk and impacts among stakeholders. The study indicates a need for legal tools to deal with the risks and effects of electric vehicles fires and highlights the lack of effective equipment and specific training requirements for handling electric vehicle fires on board vessels. The regulatory standards, including the SOLAS convention and its regulations, are discussed in terms of fire protection measures, but it is noted that these do not specifically address the risks and regulatory needs related to electric vehicles. The research indicates a potential for further investigation into the regulatory aspects and emphasizes the importance of addressing the unique challenges posed by transporting electric vehicles on ships. The pre-study points at the problems and risks associated with fires on car decks of RoRo/RoPax ferries and the regulatory changes and guidelines proposed by various international and governmental organizations. The paper highlights the slow progress in addressing these risks and the need for unified regulations and best practices. It provides a comprehensive review of the initiatives and guidelines set forth by various authorities apart from the ordinary public regulators. Other initiatives come from such bodies as the US Coast Guard, US Department of Transportation, US National Fire Protection Association, Swedish Civil Contingencies Agency, Class NK, American Bureau of Shipping, and United European Car Carriers, in addressing the risks associated with electric vehicles on ships. The guidelines and best practices encompass a range of aspects such as cargo placement, charging procedures, firefighting systems, safety measures, and preventative actions for different types of vehicles and battery systems. The paper emphasizes the need for unified regulations and the implementation of safety measures to address the risks associated with fires on car decks of vessels. The paper provides a basis for future analyses of the regulatory environment surrounding the transportation of electric vehicles on ships. It accounts for various regulations and guidelines from organizations mentioned above but also such as the International Union of Marine Insurance (IUMI), Cargo Incident Notification System (CINS), and Steamship Mutual, focusing on safety measures related to electric vehicle transportation. The paper highlights the need for practical rules and standardization in the face of uncertainty surrounding electric vehicle fires on ships. It also discusses the responsibilities and liabilities of manufacturers, sellers, importers, marketers, transporters, and passengers in the event of electric vehicle fires, emphasizing the preventive and reparatory functions of product safety regulation. The study emphasizes the necessity for further research and development of legal tools tailored to address the risks and impacts associated with electric vehicle transportation. It concludes by stressing the importance of adapting existing regulatory frameworks, such as the IMDG code, SOLAS, and fire training regulations, to accommodate the unique challenges posed by shipping electric vehicles. The paper serves as an inventory of norms and regulatory initiatives, providing a basis for further analysis and development of regulatory entities in the context of shipping electric vehicles.

BRAVE ECO – Benchmark for Reduction of Anchoring Vessels’ Emissions – Enabling Change of Operation
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This feasibility study aims to evaluate the possibilities to reduce air emissions from ships anchored in port areas and, then especially the Port of Gothenburg. For this purpose, the study uses two main approaches. Firstly, it analyses the reasons and legal/business aspects for anchoring. Secondly, this study develops a reproducible calculation model for anchored vessels' CO2 emissions. Regulation of anchoring sites are not entirely clear since international regulation partly applies, also it is not clear who is responsible for the anchoring sites. This implies that the port´s scope of action is limited mainly to the ships that are calling the port. However, also emission from other ships at in the port area has been evaluated in this study to get a broader perspective. This pre-study provides both qualitative and quantitative findings and it is produced using mixed methods, including workshops with relevant port stakeholders. It also involves different scientific disciplines and several authors from the Port of Gothenburg Authority, IVL Swedish Environmental Research Institute, Maritime Studies at Chalmers University of Technology and the School of Business, Economics and Law at the University of Gothenburg. Furthermore, in connection to this study, one bachelor's thesis and two master's theses have been carried out. The results show that it is mainly tanker ships that are anchoring in Gothenburg and that their main reasons for anchoring are related to awaiting Laycan or waiting for an available berth. The companies involved in the study generally combine time charter and voyage charter contracts to access vessel capacity. The inputs from the workshops, the interviews conducted with stakeholders and the international literature are “rather” consistent: combining just in time arrival with slow steaming has a great potential for making a business case and to reduce fuel consumption and thereby emissions. However, there are many barriers which needs to be addressed, such as: lack of trust, improving information sharing (actors now communicate via phone or email), loss of income (due to demurrage), attitudes in the industry, the “first come, first serve” concept, risk of missing estimated time of arrival and port infrastructure. Even if there are many barriers, several actors in the port already have experience of combining just in time arrival and slow steaming. In this study, we develop a reproducible emission calculation model that calculates CO2eq emissions. The emissions are partly calculated by using the ships’ positions (AIS-data) from 2019, to extract the time spent at anchor. The emission model calculates the anchored vessels' total CO2eq emissions, but the model also calculates the theoretical potential for avoiding emission by using the time at anchor to slow steam. The results show that all tanker ships that anchored outside the port in 2019, could theoretically have reduced their emissions with about 30 ktonnes CO2eq, if they would have been notified of delays 24 hours before arrival and then reduced their speed to 10 knots. The results also show that using time to slow steam have a much greater potential to reduce emissions than if the ships would only reduce the time at anchor (by using fewer ships to perform the same transport work). This is especially true for the initial speed reductions (10-14 knots). This study also evaluates the emission calculation methods and assesses the uncertainties, by comparing different sources and underlying assumptions with real world data. The study argues that it is problematic to just use default values proposed in the global emission inventory issued by the International Maritime Organization (IMO). Using default values for estimating emission makes it harder to estimate the real effect of a new policy, regulation, or incentive in the port. However, a better emission inventory requires that on-board visits are made or that data is obtained digitally. The largest calculation uncertainties now are for boiler fuel consumption and bunker ships fuel consumption at the anchorage areas.
