NEBA/SIMA or as input to company-specific risk matrix rankings. In many areas
the VEC data may be limited or less detailed, in which case ERA Acute provides a
possibility to carry out more conservative calculations.
Impact and risk illustrations used herein are for illustration only and are made
with the ERA Acute software.
2.2 ERA Acute Usage Areas
ERA Acute is an enhanced and globally applicable quantitative oil spill risk assessment methodology (meeting the guidelines set by IPIECA-IOGP 2013) and software
tool, and is applicable for various risk assessment purposes, depending on user’s need
and data availability:
1. Risk screening
2. Input to concept selection/risk comparison
3. Environmental impact assessments
4. Site-specific decision making
5. Risk estimation and evaluation/risk ranking
Evaluation and prioritization or risk reducing measures; e.g. ERA Acute can
provide quantitative input to NEBA/SIMA in order to inform oil spill response planning (IPIECA-API-IOGP 2017). Questions that can be answered using ERA Acute
are:
• What is the possible impacted area of a spill scenario?
• What are the possible consequences to species and habitats in the various
environmental compartments?
• Could there be a risk for adverse environmental effects?
• What is the probability for different consequences, i.e. what is the risk?
• Where will the highest impact be?
• In which areas to we need to prioritize oil spill response?
• How much do different mitigating measures reduce the impact or risk?
2.3 Environmental Risk Screening
The screening is the first phase in an ecological risk assessment, i.e. to decide on the
distribution of stressors in the environment and the extent of contact where exposure
could occur (US EPA 1998). ERA Acute is based on oil spill modelling of specific oil
spill scenarios which make up a DSHA (see Sect. 1.5). Oil spill modelling enables
researchers and others to estimate potential impact and utilize the results in ERAs,
including cost-benefit and decision analyses (French McCay et al. 2004). This leads
to informed decisions in strategic planning and/or operational management (Jakeman
et al. 2006).
