Our Inlet Duct and Engine Exhaust Silencers will equip a five MAN 16V 32/40 8000 KW Generators on the TCG Anadolu.
The project entails no. 5 Inlet Duct and no. 5 Engine Exhaust silencers both capable to handle 100.600 m3/h flow while achieving 35 dB(A) noise reduction.
The inlet SVR model silencers are made of galvanized steel splitter panels inserted into a painted carbon steel frame with circular inlets and outlets.
The exhaust silencers are made of AISI316 and derived from the Engine Exhaust SM40 DN1200 model with the addition of Spark Arrestors section to prevent the emission of flammable debris from combustion sources.
Stopson Italiana’s R&D team did a great job in assessing all customer requirements and delivering a fully customized solution, thus confirming our capability to leverage our wide range of standard design products optimized around project specifications.
Developed in Stopson Italiana Research and Development lab, these silencers have been field-tested on numerous industrial applications. They are principally conceived to be installed on diesel and gas engines, or on industrial low/middle power gas turbines.
These silencers are based on a absorption and/or resonance sound wave attenuation principle. Depending on the required attenuation performance, 5 models can be chosen: SM 15, SM 25, SM 30, SM 40, SM 50. The nomenclature represents also the nominal diameter of the inlet (e.g. SM15 ND 100, SM25 ND 200, etc).
In addition to Spark Arrestor (here above mentioned), some other optional features can be provided:
Seals and bolts
Supports for vertical and horizontal installation
Stainless steel or other special materials
Highly resistant absorptive material for temperatures over 530° C
The selection of the inlet filtration system is an important stage as poor quality inlet air can significantly impact the operation, performance, and life of the engine, either gas turbine or diesel/gas engine.
In facts, marine vessels need to work even in adverse conditions, thus the continuous operation is often more important than the health of the engine itself. Multiple gas turbines are used on the ships, so there is a spare if one needs to be shut down for maintenance. That can happen in case the filter is clogged, damaged, or blocked, causing – as a consequence – excessive pressure loss.
Moreover, inlet filter housings on marine vessels must be ice and corrosion resistant, due to the significant presence of salt.
Generally, when we refer to a gas turbine intake, some of the consequences of poor inlet filtration entail erosion, fouling and corrosion.
In order to minimize degradation, the metal components of the system needs to be constructed out of a stainless steel or aluminum with adequate corrosion resistant properties. Once a suitable filter system has been selected, a range of ductwork and filtration silencers is provided in order to reduce the noise of fast flowing air into the inlet manifold before reaching the compressor.
These silencers are typically of a ‘splitter type‘ configuration, to minimize pressure drop and increase the airflow into the compressor chamber.
The supply can regard even a standalone filter packages, including pulse filters for removing dust at the inlet of gas turbine packages.
Completed delivery of 12+8 combined Ventilation System Building for Gas storage plant in Sergnano and Minerbio (Italy)
Stopson has successfully fulfilled the delivery of 12+8 Ventilation System Buildings for the natural gas Compression Stations in Sergnano and Minerbio (Italy).
The supply service entails a total of twenty ventilation systems, composed by 20 filtered-and-silencedInlet Systemtogether with the same number of Soundproofed Outlet Systems with forced extraction and fireproof dumpers.
The acoustic warranty covers a noise level reduction of 30 dB(A) SPL at 1mt.The order has been completed and tested phase in these past days.
In general, the plant consists of implementation of 3 turbo-compressor to be set within the Sergnano gas infrastructure. The operations necessary for the installation of the station will be completed as a whole by mid 2018.
The total investment amount is 0.6 bln € (between 2017-2021), aimed to increase the general safety and flexibility of the area, bringing a resources’ capacity increment of 7% circa.
Thanks to a 50 years of experience in the field of industrial soundproofing, Stopson’ technical department is able to deeply analyze and propose the rightest solutions to control noise produced by the extraction systems.
The main solutions consists of rectangular or circular silencers, designed taking into account of the different noise sources and sound spectrum. The installation can be made along the piping or chimneys of emission into the atmosphere.
They can be designed and produced in standard dimensions, or in any size on request and are equipped for external air intake, in addition to return from the filter system.
How to limit the noise propagation (not only in Oil and Gas). Risks and countermeasures of a phenomenon as important as universally underrated.
The noise pollution’s matter has become a well-documented public domain anthology by now.
The World Health Organisation has reported that 40% of Europe’s population is exposed to noise levels in excess of 55dB. Moreover, noise pollution is ranked as second to air pollution, in terms of affecting our health and wellbeing, including diabetes, tinnitus and risk of heart disease.
Noise pollution in Oil and Gas
According to recent study achieved by PSE Healthy Energy and West Virginia University, some modern Oil and Gas techniques – such as hydraulic fracturing (or “fracking”) – produce noise that may increase adverse effects on human health.
Fracking can create noise at levels high enough to harm the health of people living nearby (source phys.org). “Oil and gas operations produce a complex symphony of noise types, including intermittent and continuous sounds and varying intensities,” argued PSE Healthy Energy Executive Director Seth Shonkoff.
An adequate set of policies should be specified, in order to safeguard residents and communities, such as particularly vulnerable populations (e.g. schools and hospitals). Noise mitigation techniques like perimeter sound walls, noise barriers and acoustic enclosures could represent the most appropriate solutions to hold back this phenomenon.
Noise impact on marine species
This is not all. A recent study led by International Fund for Animal Welfare, reveals the damaging impact of Oil
and Gas noise pollution on whales and dolphins. In the report, they put in evidence how new technologies should reduce their impact on marine environment during the exploration phase (source: International Fund for Animal Welfare).
Noise and Diseases
Numerous epidemiological studies have linked noise to adverse health outcomes too. They include diabetes, depression, birth complications and cognitive impairment in children.
In facts, apart from damage to hearing, exposure to excessive and constant noise can cause other health problems including:
Sleep and heart disease
Elevated blood pressure
Increased susceptibility to colds and other minor infections
Noise in Europe: limits and human tolerance
As we know, the loudness of noise is measured in decibels. Sensitivity to noise differs from one individual to the next, but experts believe that damage to hearing occurs when noise levels are higher than 85 decibels, which is about the loudness of heavy traffic.
Every year, 7 million people in Europe die from heart disease, which would put the toll from exposure to noise at around 210,000 deaths. In England heart disease kills 110,000 people annually, so the deaths linked to noise could be around 3,300.
2% of Europeans suffer severely disturbed sleep because of noise pollution. The researchers calculate that chronic exposure to loud traffic noise causes three percent of all cases of tinnitus, in which sufferers hear constant noise. Length of exposure is important too. In facts, it is not recommendable to listen to noises of 109 decibels for any longer than two minutes in row.
Noise and public health in U.S.
In US the noise phenomena has been studied deeply, causing a direct response by public health. The Health Impacts Project (HIP) provides since 2013 guidance for policy makers to identify the health consequences of potential projects by making public a national sample of health impact assessment.
Exposure Limits in U.S.
The U.S. EPA recommends an average 24-hr exposure limit of 55 A-weighted decibels (dBA) to protect the public from all adverse effects on health and welfare in residential areas. This limit is a day–night 24-hr average noise level (LDN), with a 10-dBA penalty applied to nighttime levels between 2200 and 0700 hours to account for sleep disruption and no penalty applied to daytime levels.

Crucial factors to take in account when silencers have to be installed in HVAC plants.
One of the most frequent application of soundproofing technology (like Acoustic Louvers and Intake Silencers) encompasses definitely the installation on HVAC plants. These installations release sound emission into the environment, often exceeding the allowed thresholds.
That’s because of the noise created by airflow produced by motors or fan. In other cases, the sound waves tend to break out through the walls of the ductwork and spill out into a room. Often, the noise travels the length of the ductwork and spill out the mouth at the vent.
According to their functions, these machines are arranged in outdoor places, like courtyards and terraces. Hence, the first step is to evaluate the area in which the HVAC systems should be set. That means an accurate mapping process of noise propagation, including ventilation of buildings, enclosures, and equipment rooms. Integration of noise control measures such as silencers and louvers, into the system design requires careful consideration of space constraints, fan selection and aerodynamic pressure losses.
The need is, one one hand, to reduce the noise generated by air or gas flow. On the other, to avoid of compromising the air or gas flow itself, with keeping the pressure drop as low as possible too. For these reason the Stopson Acoustic Louvers, Intake Silencers and Acoustic Enclosures can be considered suitable for these multiple industrial applications. The silencers can be added on the ventilation circuit and combined with the machine, in order to completely acoustically isolate it in any direction.
The HVAC silencers are an excellent choice for applications requiring maximum insertion loss (noise reduction), low static pressure drop, low maintenance, and quick delivery. Stopson’s offer encompasses the design and engineering assistance to integrate the HVAC system with its attenuators. Both ready-made silencers and custom built solutions are offered. The benefits are: durability, surface finishing, ease to operate.
EAC certified vent silencers successfully supplied for Oil & Gas projects in Moscow and Kingisepp
Stopson Italiana has recently completed delivery of 10 silencers to be installed at Combined Oil Refinery Unit (CORU), in the Moscow Refinery and 9 vent silencers to be installed at the new Ammonia plant under construction in Kingisepp, Russia, according to the data below:
C.O.R.U. Project – no. 10 SPM and PSP vent silencers for the Combined Oil Refinery Unit, with flow rates from 0,4 to 46 t/h. Temperatures from 150 °C to 450 °C, noise levels 80 dB(A) @ 1 m.
Kingisepp Project – No. 9 SPM vent silencers for the Ammonia plant, i.e. Steam and CO2 with flow rates from 1 to 130 t/h. Temperatures from 110 °C to 515 °C, noise level 85-110 dB(A) @ 1 m.
All silencers have engineered according to the highly demanding EPC and end user’s technical specifications. They have been manufactured in Italy in special materials, including stainless steel for internal components, and certified in accordance with EAC TR CU 010 standards for Russian market.
Stopson’s Vent Silencers can be installed downstream any device acting as a link between a container of pressurized gaseous fluid and the atmosphere. The vent silencer can also provide high or low back pressure relief for the system ensuring proper operation.
SPM Vent Silencers, used for higher flows and back pressure, are based on a combined reactive and absorptive principle for noise reduction. The gases expand to atmospheric pressure through a perforated diffuser, providing a first important step in attenuation. The flow evolves into a sound-absorbing lining section to further contribute to reach required noise residual level.
PSP Vent Silencers, used for lower flows and back-pressures, feature an expansion chamber upstream the final absorptive section with no diffuser at the inlet.
A special sound-proofed weather hood is finally heading flow and noise upward, while delivering an effective rain protection and drainage.
Vent silencers can be reactive, absorptive or combined type depending on applications and required attenuation, which can reach as much as 75 dB(A).
