  1. BE-AWARE II Final Conference, 18-19 November, Ronneby, Sweden Risk reduction and response scenarios Co-financed by the EU – Civil Protection Financial Instrument

  2. Format • Risk reduction and reponse scenarios Impact Oil on water [g] Dispersed oil in water [g] Oil on coast [g/year] Damage Oil damage[g weighted]

  3. Change • Risk reduction and reponse scenarios

  4. Scenario overview • Risk reduction and reponse scenarios

  5. VTS scenario • Risk reduction and reponse scenarios • The area where the traffic is affected by VTS is extended according to the figure • Significant effect on vessels without pilots, limited effect on vessels with pilots

  6. TSS scenario • Risk reduction and reponse scenarios • Risk of head-on collisions is reduced significantly for some of the routes. • Additional risk of overtaking collisions • Combined positive risk reduction effect of implementing the measure

  7. AIS alarm – wind turbines • Risk reduction and reponse scenarios • Risk reduction effect comparable to VTS- Only on powered collisions

  8. E-navigation • Risk reduction and reponse scenarios IMO definition E-navigation is defined as “the harmonized collection, integration, exchange, presentation and analysis of marine information on board and ashore by electronic means to enhance berth to berth navigation and related services for safety and security at sea and protection of the marine environment.” • The term E-Navigation covers a range of electronic systems which can improve the navigation and reduce the risk of accidents by providing additional information or alerting vessel crews to dangerous situations. • A cost benefit analysis of E-navigation published by IMO May 2013 reviewed the various Risk Control Options including an evaluation of their risk reducing effect of various E-navigation by an expert group • A generic risk reduction factor for all relevant types of maritime accidents can be developed based on the IMO paper. With an indicated risk reduction factor on all maritime accidents of between 8 and 17% for the individual e-navigation options in the paper, a combined reduction of 25% to illustrate the effect of E-navigation in general has been used. Based on the numbers in the report this is a conservative estimation. • This scenario is applied to the full model area.

  9. New ETVs • Risk reduction and reponse scenarios Measure the regional effect of inserting three new ETVs. It is underlined that the ETV’s actually are both, a response and risk reducing measure, as they can prevent accidents as well as being involved in the recovery of oil following a spill. • Risk reduction effect of ETVs – reduction of the oil spill by 30%. • Furthermore response capacity is included on the vessels and the response model is therefore also influenced.

  10. Night detection • Risk reduction and reponse scenarios • The combination of dedicated oil detection radars and infrared cameras on oil response vessels increases the recovery capability of these vessels during the night and in bad weather. This scenario investigates the effect of implementing these systems to an additional number of vessels.

  11. Further use of dispersants • Risk reduction and reponse scenarios Currently only the UK apply dispersants as a part of its first line of oil spill response, however other Contracting Parties may use them under special conditions or are investigating their further use. This scenario investigates the effect of applying dispersants in the full Bonn Agreement area. The same dispersant response capability as currently used for UK waters is applied for all other areas as well, including spill size and response time limitations, etc. The principle is to apply dispersants in areas with a water depth greater than 20m plus 1nm.

  12. 50% additional response equipment • Risk reduction and reponse scenarios +50% • Additional 50% usable equipment • Additional vessels where necessary to support equipment • Additional response vessel in Esbjerg.
