Langh Ship Scrubber Receives Class Approval

Langh Ship received on July 17, 2014 final class approval from Germanischer Lloyd for its exhaust gas cleaning system on m/s Laura, a 1996-built a 6,500 DWT general cargo vessel equipped with a 6 MW main engine. “The technology had already been accepted earlier, but now the documentation is also finalized,” said Reino Verosaari, Senior Technical Adviser. “In a way, this is like crossing the finish line.” Langh Ship is a shipping company that has developed its own closed loop scrubber. The system uses caustic soda to neutralize the SOx in the exhaust gas and cleans the process water so that it can be led to the sea. The residual is collected in such a dry form that the compact waste can be transported to the nearest waste treatment plant. The scrubber was recently made available also to other shipping companies through DeltaLangh Ltd, a joint venture company owned by Deltamarin Ltd and Oy Langh Tech Ab, which is part of the Langh companies. Deltamarin provides engineering and consulting services for the shipping, shipbuilding, naval, marine and offshore industries worldwide. “DeltaLangh has already begun installing similar exhaust gas cleaning systems on our other four vessels. The installations are expected to be fully operational on January 1, 2015, when the new regulation comes into force,” said Commercial Manager Laura Langh-Lagerlöf, who herself has been actively involved in the development process.

Mitsubishi Heavy Industries, Ltd. (MHI) and Mitsubishi Kakoki Kaisha, Ltd. (MKK) say they have jointly developed a "Hybrid SOx Scrubber System" that efficiently removes sulfur oxides (SOx) from exhaust gas emitted by marine diesel engines – the first in Japan to comply with the more stringent SOx emission regulations that will take effect in designated emission control areas (ECA) in 2015. The system is capable of scrubbing exhaust gas from the combustion of fuels emitted from


Carnival to Develop New Emission Reduction Tech

Carnival will drydocks 9 ships in 2014; 16 ships in 2015 and 7 ships in the first half of 2016 to install new exhaust gas cleaning systems.

In the quest meet stringent new emissions regulations, cruise industry major Carnival Corp. earlier this month reached an agreement in principle with the U.S. Environmental Protection Agency (EPA) and Coast Guard to develop its own advanced emission control technology to be used in waters surrounding U.S. coasts. According to the EPA, Carnival will develop and deploy a new exhaust gas cleaning system on up to 32 ships over the next three years to be used in Emission Control Areas (ECAs)
