Risk analysis

Safetec has extensive experience in planning, conducting and implementing risk analyses as a tool for risk management.


EL-HAZID is a structured, systematic methodology that is used to identify and document potential hazardous events and operational conditions that may arise. EL-HAZID is also known as ELHAZ, SAFOP, Electrical HAZOP, and eHAZOP.

We have experience with performing EL-HAZID reviews related to design or modification of electrical systems. The developed EL-HAZID methodology is designed to review potential failure modes, operational conditions, and system design. Safetec facilitate EL-HAZIDs as an independent third party.

Safety Adviser

A typical EL-HAZID will comprise the following steps:
  • Planning of workshop
  • Execution of study during workshop
  • Documentation of observations and actions that arise in the meeting
  • Preparation of deliverables to client
  • Preparation and review of relevant background information

Quantitative risk analysis (QRA)

Quantitative risk analysis is a well-established method for decision support and measuring the risk level against predefined criteria.

We have carried out many quantitative risk analyses of varying sizes and scope, following current regulations, standards, and company-specific requirements/guidelines for various plants and installations.

A quantitative risk analysis should be performed in different phases of a project, from concept selection, through design development, development, operation, maintenance, and modifications, to liquidation and removal.

Methods and tools we use may include:
  • Frequency calculations for all serious incidents
  • Consequence assessments (fire and explosion loads, smoke and gas spreading)
  • Loss of security features
  • Quantification of risk for personnel, environment, and material values

Risk and vulnerability analysis

A risk and vulnerability analysis is about identifying possible incidents and assessing the risks and vulnerabilities associated with these incidents.

Vulnerability analysis is based on a versatile methodology used in several areas and is rooted in various laws and regulations.

The vulnerability analysis often focuses on potential harmful events (hazards and threats).

Examples of laws and regulations where risk and vulnerability analyses are anchored:
  • The Civil Protection Act (comprehensive risk and vulnerability analysis)
  • The Planning and Building Act (risk and vulnerability analysis in areal planning)
  • Regulations on municipal emergency preparedness - § Comprehensive risk and vulnerability analysis

HAZID and other hazard identification methods

Safetec is a leading provider of HAZID and other hazard identification services.

We perform many HAZIDs annually for many different customers, both in connection with risk analyses and individual operations.

Safetec contributes with highly competent personnel with expertise in technical systems and operational and organisational matters. We can put together teams with the right competence and experience for each HAZID so that we can contribute to risk identification and documentation in the best possible way. In addition to facilitating HAZID meetings, we also provide training for personnel in HAZID methodology.

Principal Safety Adviser

A typical HAZID study will consist of the following steps:
  • Preparation and review of background information
  • Planning of workshops in collaboration with the customer
  • Implementation of HAZID through workshops
  • Documentation of observations and recommendations
  • Preparation of delivery to the customer

Reliability, availability, maintainability and safety (RAMS)

The RAMS process ensures properties for an infrastructure project related to security, accessibility, and punctuality.

Safetec is a leading professional environment with high competence and large capacity.

In addition to complying with current regulations, a good RAMS process provides cost-effective solutions for roads and railways with high safety and accessibility. Our advisors take care of all steps in the RAMS process, from establishing plans in the early phase until the final safety certificate has been prepared. This gives the customer documentation that selected solutions have been risk assessed, and all relevant requirements and goals have been met.

Early involvement with qualitative RAMS assessments in design activities is important. Then we achieve good RAMS properties throughout the life of the operating phase, which applies to both new or significantly changed infrastructure.

An adequate RAMS process is ensured by carrying out the following main activities:
  • RAMS plan
  • System descriptions
  • Risk and RAM assessments of alternative solutions and chosen concepts in a life cycle perspective
  • Register for hazards and RAM conditions, both general and project-specific
  • Involve RAMS as an integral part of the design and operational activities
  • Verify and validate
  • Prepare security certificate

Tunnel safety

Safetec has expertise in tunnel safety, both for road tunnels and railway tunnels.

We perform risk analysis, RAM and LCC evaluations, emergency preparedness analysis and contingency plans for tunnels.

We have carried out many tunnel safety studies of varying sizes, scope and different phases, from concept through design development and operation.

Methods, tools, laws and regulations we use include:
  • NS 5814
  • "Tunnelsikkerhetsforskriften"
  • N500
  • N301

Ship traffic data and collision analysis

For 30 years, Safetec has helped several customers with risk assessments related to shipping traffic and collisions.

Safetec has the expertise to perform tailor-made analyses of ship traffic data adapted to the customer's needs.

Risk analyses include collision risk for offshore installations, pipelines, articulated traffic, aquaculture and location clearance, harbors, and jetties near buildings and bridge projects. In our analysis, we use modelling tools for calculating collision risk against various units at sea, such as wind turbines, cages, and facilities.

Examples of Modelling tools/analyses:
  • COAST:
    GIS tool for analysis of AIS data
    A Modelling tool for collision risk at sea. Uses location-specific information from COAST, weather data, etc.
