Oil spill risk assessment and response planning

DNV evaluates oil spill risks of planned activity and identifies cost-efficient response options

Good company practice and regulatory requirements entail mapping the environmental risks of potential oil spills and identifying preparedness and response options.

Our oil spill risk assessment service will help you achieve cost efficient oil spill preparedness and response solutions including plans, which ensure reduced environmental and socio-economic impacts.

DNV can identify and assess relevant risk-reducing measures, ensure documentation is in accordance with government regulations and help you implement oil spill preparedness solutions.

We perform quantitative oil spill risk assessments using state-of-the art 3D oil spill modelling tools combined with up-to-date geo-spatial data on sensitive species and habitats. Spill modelling can be preceded by blowout and kill studies, well-specific assessments based on reservoir conditions, benchmarking analysis, or review of data and statistics.

Our oil spill risk assessments services build on internationally recognised tools and guidance documents and are compliant with standards specified by operators, oil spill response contractors and authorities.

We also make an ongoing contribution to the technological development of oil spill response equipment.

Our oil spill risk assessment services include:

  • A detailed and quantitative environmental risk picture based on the ERAacute method, and company specific environmental risk acceptance criteria
  • Identification of prioritized and environmentally sensitive areas
  • State of the art 3D oil spill fate and trajectory modelling (OSCAR)
  • Assessment of likelihood and impacts of oil spill scenarios
  • Identification of risk reducing measures
  • Net Environmental Benefit Analysis (NEBA)
  • Spill impact mitigation assessment (SIMA)
  • Oil spill contingency analysis and response plans
  • Customized solutions for near shore and shoreline response
  • Customized solutions for cold climate (Arctic) oil spill preparedness and response
  • Gap-analysis of current oil spill response solutions
  • Operational oil spill support and technology advisory
  • Verification and support services for oil spill response technology and equipment testing
  • Verification of oil spill response technologies and plans.
