Environmental Risk Assessments

SensE performs quantitative environmental risk assessments using methods described in the OLF guidelines for activities on the Norwegian Continental Shelf.

SensE draws upon best available environmental data sets, blowout simulations and use of the OSCAR oil drift model. The scope and detail of the analysis may range from simple to complex depending on the activity and client requirements and needs. Results are related to client acceptance criteria.

Applying State of the Art Methods

Methods and approaches for quantitative environmental risk assessments in Norway were developed as a means to arrive at objective and intercomparable expressions of the environmental risk associated with an activity. Environmental risk assessment and overall risk reduction are specified in the Norwegian regulatory framework for offshore activities. For complex and sensitive activities requiring more comprehensive analyses, SensE incorporates additional methods to address issues in greater detail. When working in areas outside of the Norwegian continental shelf, SensE adopts or develops alternative approaches to satisfy the governing regulatory requirements, client objectives, as well as relevant international methods and standards for petroleum operations.

Achieving Defensible Results

SensE understands that environmental performance is a key factor in the reputation and credibility of businesses and organizations. They maintain the highest quality standards in their work, making sure that environmental questions are analysed and answered based on the best available tools and a solid scientific basis for managing environmental risks in sensitive areas. In particular, the quality of an environmental risk assessment is highly dependent on the quality of input data and a complete understanding of the relationship between input and output at each step in the analysis. SensE maintains access to the best available data on the distribution of sensitive resources and valued ecosystem components by regular dialogue with data providers and scientific institutions.

Added Value for Our Clients

SensE works closely with each client to understand company perspectives before proposing practical actions that fulfil the intentions expressed in the risk assessment procedures. In this way, SensE serves as an “integrator,” retrieving and evaluating cross-disciplinary information and raising issues and actions for operators to consider during the well planning process.

SensE is the only provider in Norway running high resolution oil drift simulations to identify the full range of potential outcomes of an accidental oil spill. Our clients receive risk assessment results for all species for which there exists sufficient data.

SensE recognises the importance of maintaining transparency and credibility in the performance of risk assessments. Our clients have the option to request that the results of an environmental risk assessment are made available through an intuitive user interface accessible through the SensE project web site.

Akvaplan-niva in Action

SensE performs risk assessments in areas with unique environmental features.  The coast of the small island Runde, located in Møre og Romsdal County, Norway is an important seabird sanctuary. Approximately 500,000 seabirds inhabit this tiny island with an area of only 6 km2. <span>Image by Geir Morten Skeie</span>
Røst, located off the southwestern tip of the Lofoten archepelago has one of the biggest birdcliffs in the North Atlantic, with puffin colonies, as well as colonies of shag, kittiwake, and cormorants. <span>Image by Akvaplan-niva</span>
