    Opis:
    Lake Saimaa is the largest lake in Finland and the Saimaa inland waterway network is one of the main transport corridors for merchant shipping. The Saimaa inland watercourse is a challenging operating environment due to shallow waters, narrowness of the fairways, fast currents as well as the sensitiveness of the environment. It is recognised that the heavy vessel traffic poses a risk of oil pollution. An oil spill incident in inland waters has a high potential for contaminating shorelines and affecting populated areas. Responding to such an incident involves several governmental and regional authorities, agencies and voluntary organisations. Inter-agency coordination is considered a key element in incident management. Several exercise types can be used to train multi-agency collaboration in joint response operations. This paper analyses the benefits of tabletop exercises in the strengthening of joint preparedness and contingency planning. Paper compares the outcomes of discussion-based exercises with operations-based drills and full-scale exercises. The analysis is based on four oil spill response tabletop exercises and five oil response drills conducted in Saimaa region in 2017–2018. Different types of exercises make it possible to focus on different aspects of the response operation. Operations-based exercises are useful in improving technical skills and testing procedures and the functioning of the equipment. Due to time restrictions, the equipment deployment drills usually focus on a specific function or a single task. Tabletop exercises can be used to assess contingency plans on a strategic level. Tabletop exercises offer an opportunity to clarify roles and responsibilities, discuss priorities and establish inter-agency agreements. The advantages of tabletop exercises include their flexibility in scenario-building, low-cost implementation and the possibility to study a longer time span in order to gain a more holistic view of the response operation.

    Opis:
    Risks in the maritime domain have various sources, of which the transportation of oil and other noxious products is one of key concern to industry and public stakeholders. Operational or accidental releases of oil or other pollutants from ships or offshore facilities into the marine environment can have disastrous effects on the marine ecosystems, while also leading to very significant economical losses. Therefore, national states have implemented various mechanisms for preventing and responding to pollution in the maritime domain, with activities which are often embedded in regional cooperation frameworks clustered around certain sea areas. To support collaborative, harmonized, and risk-informed oil spill Pollution Preparedness and Response (PPR) planning for response authorities, the Baltic Marine Environment Protection Commission (HELCOM), together with its research partners, and with extensive end-user and stakeholder inputs, have developed the OpenRisk Toolbox. This toolbox includes several risk assessment tools and techniques, which can assist in providing answers to a range of PPR risk management questions in a range of organizational contexts. To better understand and ensure the applicability and usefulness of the OpenRisk Toolbox, a workshop was organized where some of these tools were tested. Selected end user and stakeholder views on the perceived usefulness of the tools were collected and analyzed. Another workshop focused on further development needs to implement the tools in organizational practices. This paper first presents the OpenRisk Toolbox, then describes the settings of the workshops. Finally, a summary of the end-user and stakeholder views on the tested tools, and on future development needs, is given.

    Opis:
    In the process of oil exploitation and transportation, large amounts of crude oil are often spilled, resulting in serious pollution of the marine environment. Forecasting oil spill reverse trajectories to determine the exact oil spill sources is crucial for taking proactive and effective emergency measures. In this study, the backward-in-time model (BTM) is proposed for identifying sources of oil spills in the East China Sea. The wind, current and random walk are three major factors in the simulation of oil spill sources. The wind drag coefficient varies along with the uncertainty of the wind field, and the random walk is sensitive to various traits of different regions, these factors are taken as constants in most of the state-of-the-art studies. In this paper, a self-adaptive modification mechanism for drift factors is proposed, which depends on a data set derived from the drifter buoys deployed over the East China Sea shelf. It can be well adapted to the regional characteristics of different sea areas. The correlation factor between predicted positions and actual locations of the drifters is used to estimate optimal coefficients of the BTM. A comparison between the BTM and the traditional method is also made in this study. The results presented in this paper indicate that our method can be used to predict the actual specific spillage locations.
