The current spill response capability in Finland is built to respond to oil spills caused by heavy fuel oils and the most transported oil cargoes. However, the implementation of the Sulphur Directive in 2015 changed the fuel profiles of the ships: prior to the new regulation ships operating in the Baltic Sea mainly used heavy fuel oil (HFO), whereas now ships use marine gas oil (MGO DMA) or marine diesel (MDO DMB) known as marine distillate fuels. This paper reviews the effectiveness of the current recovery techniques in responding to spills of marine distillate fuels based on the oil recovery field tests. The results indicate that conventional recovery techniques are only partially applicable to marine distillate fuels, which calls for a reassessment of the marine oil spill response capability and further research. The use and availability of low-carbon marine fuels will continue to increase as emission regulations become more stringent. This will require a continuous assessment of the oil recovery capabilities and the adaptation of spill response preparedness accordingly.

A smart solution for assessing the consequences of pollution on the coast, on flora and fauna but also by accounting for the total costs of the equipment used in the response to pollution is a system for assessing, coordinating and simulating the risk situation with the help of a mathematical model implemented on a simulator. The mathematical model for the simulation of the event of pollution is the latest generation and take into account all the meteorological factors of the sea and air, as well as all the physico-chemical parameters of the substances involved (dispersion, surface tension). The simulator is used for the realistic modeling of a crisis situation and it is useful for both marine officers and emergency situation officials. The simulator will be used as an educational instrument enabling the interactive study of the different emergency situations. In this paper we present the simulation of incident and the creation of response resources. The scenario incident is for KAPTAN M cruise ship that left the tourist port of TOMIS Constanta, Romania, having on board 20 passengers and a number of 15 crew members, and which collided with the oil ship EVIA Oil FIVE, having on board the quantity of 4200 MT crude oil. As a result of the collision, the passenger ship suffered a breach (water hole), on the starboard board, breach by which the ship began to ambarce sea water and in the car compartment a fire was produced. Containment and recovery of an oil spill during the exercise will be simulated through activation and control of response resources. The resources involved in the operations are divided into: platforms, equipment and personnel. The results of simulation is the list of response resources specified in the scenario together with their parameters, which can be exported into a text file. With this simulation tools you can efficiently appreciate the cost of resources in due time, avoiding material and human damage.

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.

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.

Marine oil spill response operation requires extensive vessel manoeuvring and navigation skills. At-sea oil containment and recovery includes both single vessel and multi-vessel operations. Towing long oil containment booms, several hundreds of metres in length, is a challenge in itself. Boom deployment and towing in multi-vessel configurations is an added challenge that requires precise coordination and control of the vessels. Efficient communication, as a prerequisite for shared situational awareness, is needed in order to execute the response tasks effectively. In order to gain and maintain adequate maritime skills, practical training is needed. Field exercises are the most effective way of learning, but especially the related vessel operations are resource-intensive and costly. Field exercises may also be affected by environmental limitations such as high sea-state or other adverse weather conditions. In Finland, the seasonal ice-coverage also limits the training period to summer seasons as regards the vessel operations of the Fire and Rescue Services. In addition, the sensitiveness of the marine environment restricts the use of real oil or other target substances. This paper examines, whether maritime simulator training can offer a complementary method to overcome the training challenges related to the field exercises. The objective is to assess the efficiency and the learning impact of simulator training, and the specific skills that can be trained most effectively in simulators. This paper provides an overview of learning results from two oil spill response pilot courses, in which maritime navigational bridge simulators together with an oil recovery simulator were used. The courses were targeted at Fire and Rescue Services responsible for near shore oil spill response in Finland. The competence levels of the participants were surveyed before and after the course in order to measure potential shifts in competencies. In addition to the quantitative analysis, the efficiency of the simulator training was evaluated qualitatively through feedback from the participants. The results indicate that simulator training is a valid and effective method for developing marine oil spill response competencies that complements traditional exercise formats. Simulator training provides a safe environment for assessing various oil containment and recovery tactics. One of the main benefits of the simulator training was found to be the immediate feedback the spill modelling software provides on the oil spill behaviour as a reaction to the response measures.
