leader in industrial soundproofing systems, has recently acquired the brand SilencERmarine, with the aim of increasing its offering in the market of noise control for marine equipment.

SilencERrmarine products and services’ addition to its current portfolio will allow to further strengthen Stopson Italiana’s presence on the naval/marine market with interesting growth prospects, ready to accept the challenges of the competitive global market.

SilencERmarine is a well-recognized brand in the world of marine equipment and noise control, specialized in the production of soundproofing systems for the luxury sector of the boating/yachting industry.

SilencERmarine proven know-how covers the development, manufacturing, and turn-key installation of the following:

• Stainless steel and GRP (Glass Reinforced Polymer) silencers,
• Complete exhaust systems (R.I.Na. – Italian Naval Registry, D.N.V., and Lloyd’s Register approved),
• All components and accessories required to supplement installations of the above products

Here at Stopson Italiana, we believe the experience and knowledge in noise attenuation of marine/naval equipment from SilenceERmarine, combined with the strong and global sales network of Stopson Italiana, can increasingly sustain the growth of the Company.

For 50+ years Stopson Italiana has been offering advanced technological solutions for the leading players in fields such as Oil & Gas, Power Generation, and Industrial sectors, guaranteeing high-efficiency performance in terms of a significant reduction of noise and optimization of operating performance at customers’ facilities.

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:

• Flanges
• Counter flanges
• 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.

A great effort has been spent by Stopson Italiana’s engineers to design custom Inlet Duct air filtration systems.

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.
