Refining, natural gas liquefaction and power generation for oil and gas industry often involve combustion turbines with an output above 40 MW.

In such cases, the combustion turbine itself, a gas fuel module and a water injection module are powerful noise sources of which the impact must be limited to protect workers in the power plant and neighbors as well.

Noise barriers walls and sound enclosures (both : with a steel structure able to withstand high loads due to wind and snow and seismic load as well, and with removables panels for walls and roof, if any) are constructions being appropriate for such a purpose, as long as they are compatible with maintenance requirements.

To enable the ventilation of the turbomachinery components, sophisticated ventilation systems are needed, involving fans meeting ATEX (for Explosive ATmospheres) requirements - based on a european directive - and silencers to limit (through openings needed for air inlet and outlet) the propagation of noise emitted by encapsulated hardware and also due to moto-ventilators themselves.

The features associated with soundproofing equipment in Oil and Gas sector are many and varied: they require multidisciplinary skills.

The existence of domestic regulations for building and for electrical works always involve complex works for project management and documentation preparation, for soundproofing works in the oil and gas sector : the stamping by local authorities is sometimes an essential phase.

Robust experience in metallic construction, electrical works and administrative tasks is required to face succesfully all challenges related to such projects, especially when related to overseas installations or/and petrochemical sites.

ITS has participated in the construction of soundproofing devices for 3 combustion turbines on a carabbean island in the context on an oil and gas project.

As often in such cases, it came to the design and construction of buildings whose envelope could oppose the propagation of noise, as well as the soundproofing devices of associated ventilation systems.

The use of ITS business partners being seasoned for such projects of soundproofing works in oil and gas has allowed a smooth project management.
