Provide practical safety expertise to industries handling hazardous material from conceptual phase to post-installation start up

Support Technip operating centers on specific safety issues on their projects

Our experience is based on:

A team of experts with specific softwares

Hundreds of specific safety studies performed in-house since 1980 (Technip is accredited as third part for the French Environment Ministry)

Main references:• Oil and Gas (Shell, Total, BP, Exxon, Engie, etc.)• Defense/Space (Airbus, MBDA, ESA, Thales, etc.)• Chemicals (Solvay, Arkema, ENI-Versalis, etc.)• Nuclear (EDF, Areva, CEA, etc.)• Fertilizers (Yara, Borealis)

Safety experiments performed in the field of fire, explosions and cryogenic releases

Accident investigations (including major accidents like AZF Toulouse and Total La Mède)

Our difference

We combine both competencies of EPC contractor and technical safety expert consultants.

From risk assessment to structural design, Technip’s Paris office - HSE Design Expertise & Modeling department can provide our clients with in-house tailor-made technical safety studies considering their specific needs. Our fully integrated approach reduces interfaces between stakeholders and offers optimal and cost effective solutions.

Different methodologies of Risk Analysis may be selected according to the project phase or context and technology.

These methodologies result in recommendations to improve the safety of the system and may be incorporated in permitting process to help the owner to support the technical options in front of local authorities.

Our experts provide the following main services:

Perform Quantitative Risk Assessment (QRA) using methodologies and tools:

DNV PHASTRISK Frequency analysis: DNV Leak® v3.2 Likelihood of accidents: Fault tree, event tree, bow-tie (Risk Spectrum®, GRIF® software) SIL assessment according to standards as IEC61511 or ISA TR84.02, fault tree analysis – Markov (Risk Spectrum®, GRIF®,

with reliability data base ex OREDA, SINTEF, EXIDA)

Perform third-party analysis on safety studies

Optimization of toxic, fire and gas detection according to consequence analysis studies/F&G Mapping

Perform quantitative assessment of safety distances in real time during Risk Assessment sessions, using in-house software (PREDIT)

Training course packages on software use (e.g. DNV PHAST, GRIF etc.)

Risk analysis

HSE Design Expertise & Modeling 5

An in-depth understanding of physical phenomena and a wide range of modeling tools allow the assessment of explosions, fires, gas dispersion and cryogenic releases phenomena. Our approaches range from engineering correlations to the use of more advanced CFD tools (FLACS®, AUTOREAGAS®, FDS, KFX®, LS-DYNA®, EOLE®). CFD tools have been intensively used at Technip for more than 15 years.

Through R&D programs and internal developments, HSE experts also worked on creating new methods or improving and adapting current modelling approaches to meet the ever evolving industry needs.

Our services range from spot support on specific safety issues to probabilistic Fire and Explosion Risk analysis (in-house tool ExploRisk). We can also provide dedicated training on hazard modelling and its integration in the overall design process. One of our defining feature is also the ability to deal with non standard /unusual safety issues.

Some examples of calculations

Gas explosion on offshore/onshore facilities Flammable/toxic gas dispersion Pool fires/jet fires in complex geometry Explosive phenomena (BLEVE, vessel burst, high explosive, etc.) Bund overtopping due to catastrophic rupture of storage tank Visibility and escape issues (in-house tool ERIAS) Cryogenic releases (LNG, etc.) behaviour and thermal exchange with substrates (JIP tests validated CFD code EOLE®)

Gas dispersion (FDS)

Offshore gas explosion (FLACS)Cryogenic spill (EOLE)®

Bund overtopping

Pool fire (FDS)

Aim: Provide accurate modeling of hazardous phenomena according to clients stakes, needs, schedule and budget.

Effects modeling: Gas dispersion, cryogenic spillage, fire and explosion

HSE Design Expertise & Modeling6

Many of safety critical elements (structures, equipment and piping) shall be designed or verified against Major Accidental Events or human threat in order to fulfill their function.

The calculation of response of structures and equipment against accidental loads or human threat requires a dedicated approach compared to common load cases (e.g. gravity, operating conditions). Hence common design rules should be modified in order to take into account the magnitude, short duration and low frequency of these loads otherwise the design will be highly conservative or not possible.

We have continuously developed expertise and methods for more than 20 years. Our services range from the simple ones (mostly from defense) to the most advanced 3D Non-Linear Finite Element Analysis (NFLEA) tools such as ANSYS® and LS-DYNA 3D®.

Our integrated approach also gives the opportunity to combine CFD results (fire, explosion, etc.) with NLFEA in order to:

Optimize design, cost and weight Evaluate the integrity of existing mitigation barriers.

Finally as part of an engineering company, we also provide practical and cost effective design solutions and assistance up to implementation/construction phase.

Accident investigation:

Although unlikely, incidents do occur on existing installations. From potentially lethal accident to multiple fatalities major accident, it is always necessary to identify what went wrong (historically safety regulations have always evolved after a major accident). We have developed a rigourous and methodical procedure to determine accident scenarios.

The investigated accidents include:

Major accidents in a refinery and in an industrial site

Accident with internal casualty and lethal accident

Malfunctioning on a ground flare

Experiments:

Small scale gas explosion test to assess blast reflection factor

Fire test on nuclear containers

Detonation tests on fertilizers

Cryogenic releases tests on carbon steels, cryogenic spill proctection and water, through a joint industry project led by Technip.

Experiments are an opportunity to better understand physical processes involved in:

modeling accidental phenomena.

Our experts have conducted and participated in a significant number of tests outlined below
