Acoustic fireproof shelter container for a turbogenerator set

Issues

The aim of this project was to design, manufacture and install a protective enclosure to house and acoustically isolate a turbine-generator set. The turbine is supplied with natural gas and drives a generator via a gearbox. This unit was part of a natural gas decompression plant installed in France.

In addition to acoustic performance, high standards were set for the Shelter's fire resistance.

Ecib solution

We designed and built the acoustic shelter in three sub-assemblies to meet the project requirements. The enclosure is designed to limit the external effects of an explosion inside the site.

QUASAR' acoustic explosion vents act as valves in the event of an explosion. These QUASAR' vents are dimensioned to open at a pressure of 30 mbar, while the rest of the Shelter's structure is designed for a minimum resistance of 100 mbar.

To ensure protection against internal fires, the acoustic enclosure features high fire resistance performance for a 60-minute fire resistance guarantee.

A fireproof container solution designed for real industrial constraints

Fireproof containers are now an essential solution to meet growing demands in terms of fire safety, storage of sensitive products, and regulatory compliance. In many industrial, logistical, or technical environments, simple storage is no longer enough: it must be secure, compartmentalized, and able to withstand fire for a specified period of time.

At ECIB, fireproof containers are not just standard products. They are comprehensive solutions designed to adapt to the specific constraints of each site, whether for storing flammable materials, hazardous products, technical equipment, or high-risk areas.

Understanding the fire resistance levels of a fireproof container

A fire-resistant container is characterized by its fire resistance, expressed in minutes:

• 30 minutes
• 60 minutes
• 90 minutes
• 120 minutes (REI120)

These durations correspond to the container's capacity to:

• maintain its mechanical stability,
• prevent the spread of flames,
• limit heat transfer to the outside.

The choice of resistance level depends on several factors:

• nature of the products stored,
• container installation (indoor or outdoor),
• proximity to buildings or sensitive areas,
• regulatory obligations specific to the activity.

What is the practical use of a fireproof container?

Fireproof containers are used in many industrial and technical contexts:

• storage of flammable or combustible products,
• storage of chemicals,
• protection ofsensitive equipment,
• securing maintenance areas,
• creation of a self-contained fireproof technical room.

Thanks to its design, it can contain a fire outbreak, limit material damage, and protect people, while allowing sufficient time for security or emergency teams to intervene.

Key elements that guarantee the performance of a fire-rated container

The performance of a fire-rated container depends on several essential components:

• reinforced metal structure, capable of withstanding high temperatures,
• fire-resistant insulating walls, incorporating specific materials with high thermal resistance,
• certified fire doors, often equipped with automatic door closers,
• secure ventilation systems, designed not to compromise fire resistance,
• additional safety options: retention, detection, controlled ventilation.

At ECIB, every element is carefully considered to ensure overall consistency in the level of protection, with no weak points.

Standard fireproof container or customized solution: a strategic choice

Many fireproof containers on the market are offered as standardized models with fixed dimensions and configurations.
These solutions may be suitable for certain simple uses, but quickly reach their limits when specific constraints arise.

ECIB stands out for its ability to offer:

• custom dimensions,
• suitable interior fittings,
• specific access points (doors, hatches, technical passages),
• optimal integration on site.

This customized approach optimizes the safety, functionality, anddaily operation of the container.

A response to regulatory and insurance requirements

The use of a fireproof container is often dictated by:

• fire regulations,
• the requirements of insurers,
• obligations related to classified facilities (ICPE).

A well-designed fireproof container allows you to:

• reduce the risk of accidents,
• secure the facilities,
• respond to compliance audits,
• reassure operators and partners.

ECIB supports its clients in this process by offering solutions that comply with current standards and the specific constraints of each sector of activity.
