A large vessel owned by COSCO Shipping will host a pilot installation of a new scrubber technology developed by Mitsubishi Heavy Industries (MHI).
The rectangular ‘Active Funnel’ scrubber is designed for ease of installation on vessels with limited space. MHI said that the system is most suitable for very large container ships with high exhaust gas emissions, where it can be installed in narrow spaces between the container holds, maintaining the vessel's cargo capacity.
The system can clean emissions from 3.5% sulphur heavy fuel oil to below the 0.5% sulphur cap to be introduced in 2020 and the 0.1% limit demanded in emission control areas. The supplier noted that the technology was developed in partnership between MHI’s shipbuilding division and Mitsubishi Hitachi Power Systems, which has built several desulphurisation systems for thermal power plants. These facilities can produce seven to twenty times the exhaust gas of large marine engines.
The Active Funnel is provided as one module, making it easy to retrofit. It is available in either open-loop or hybrid configurations. The product range will be extended to enable even more power-hungry vessels, including very large crude carriers and ore carriers, to use the technology.
Mitsubishi Shipbuilding Co and Mitsubishi Hitachi Power Systems will work with COSCO Shipping Heavy Industry (Dalian) Co to install a demonstration project on a China COSCO Shipping vessel. MHI will also discuss a sales and manufacturing collaboration with the Dalian shipyard.
