Consequence Risk Assessment

Risk can be defined as a combination of the likelihood of an event and its consequence.

The Process Risk Assessment aims to quantify both consequence and likelihood of the Major Accident Events (MAEs) identified in the facility.

Consequence assessment will estimate the severity of the damage to people safety, environment and assets and the frequency assessment will provide the associated frequency of occurrence.

Quantitative Risk Assessment will provide details inputs for Risk based decision making during the Risk Management phase.

Results of the Risk Assessment will be also used to optimise the Design Accidental Loads of critical elements, to assess the survivability of the emergency systems, to optimise the Escape, Evacuation and Rescue means and to ensure adequacy of the Temporary Refuge.

Flare Radiation Analysis

 Companies wishing to achieve a controlled level of safety and to comply with local Authorities’ safety requirements need to demonstrate that flares are properly designed and that risks related to flare radiations are managed and reduced to an acceptable level.

Vent Dispersion Analysis

In order to achieve a controlled level of safety and to comply with local Authorities’ safety requirements, vents are to be properly designed and risks related to vent dispersion are to be managed and reduced to an acceptable level.

Escape, Evacuation & Rescue Analysis

During any emergency situation, personnel must be able to escape from hazardous areas towards temporary refuges, to evacuate from the facility and to be rescued and taken to a place of safety. Outputs from Fire and Explosion Analysis (FERA), Smoke and Gas Dispersion Analysis (SGDA) and recommended practices along with understanding of personnel distribution are commonly used to develop Escape, Evacuation & Rescue Analysis (EERA).

Emergency System Survivability Analysis

 On any facility, an EMergency System Survivability Analysis (ESSA) should be carried out to ensure the availability of emergency systems during major accident events such as fire, explosion or hazardous gas release.

Dropped Object Risk Assessment

During any lift in a facility, there is a possibility that the lifted object is dropped resulting in equipment damage, structural damage or a release of hydrocarbons. For an offshore unit the dropped object study considers topside, subsea equipment and structures.

Marine Traffic & Collision Analyis

Marine traffic can be analysed using Tecnitas DrifTec software, to assess the probability of collision in a given zone. Then a fast yet accurate tool, based on “super-elements” method, can be used to evaluate the consequence of a collision between a ship and another ship, an iceberg or a fixed structure (offshore platform, offshore wind turbine,…).
