Swiss power and automation technology group ABB Turbocharging has launched a commercial turbocharging air outlet silencer package to reduce noise levels on board ships.
The turbocharger noise reduction package has been designed to help reduce engine room noise, enabling it to comply with the International Maritime Organisation (IMO) regulations as per the Safety of Life at Sea (SOLAS) limits.
The revised SOLAS regulation requires new ships to be constructed to reduce on-board noise and to protect personnel from noise on board ships.
The solution is applicable for on A100-L and A200-L series turbochargers and features special noise damping elements to meet IMO noise emission standards revised in July 2014.
ABB Turbocharging Low Speed head of product line Joachim Bremer said: “With up to a 5dB reduction in noise emissions, the noise level perceived by a human ear is almost reduced by half, thus making a considerable contribution to the noise level limit set by the IMO SOLAS regulations.
“The development of the air outlet silencer underlines our focus on the safe operation of our turbocharging products, and on reducing environmental pollution.
“In creating a quieter working environment for seafarers, we are bringing to our customers the ABB Group commitment to occupational health and safety.”
Additionally, ABB has introduced its smallest turbocharger for two-stroke marine engines called the A160-L for low speed engines.
The turbocharger features pressure ratios up to 5.0 enabling minimized fuel consumption for IMO Tier II and Tier III NOx compliance.
Bremer added: “With the A160-L we are now able to deliver the same benefits for small-bore low speed engines.
“In addition, we have listened to our customers’ requirements to maximise uptime, resulting in a product that is easier to maintain, with longer service intervals so operators can be assured of their turbochargers’ reliability, literally from dry dock to dry dock.”
This week, ABB announced the decision to supply breakthrough technology for Smart Substations in China for the State Grid China Corporation’s (SGCC ) next-generation smart substations project.
It will be the world’s first DCB with FOCS application at such a high voltage level, stated the company.
The project will see ABB install a 363kV disconnecting circuit breaker (DCB) with Fiber Optic Current Sensor (FOCS) integrating three substation functions, circuit-breaking, disconnecting and current measurement, in one single component.
