www.marinelink.com 63 Langh Ship received fi nal class approval from Germanischer Lloyd for its exhaust gas cleaning system on m/s Laura (pictured), a 1996-built a 6,500 DWT general cargo vessel equipped with a 6 MW main engine. Langh Ship is a shipping company that has developed its own closed loop scrubber. The system uses caustic soda to neu- tralize 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 Deltama- rin Ltd and Oy Langh Tech Ab, which is part of the Langh companies. Deltamarin provides engi- neering and consulting services for the shipping, shipbuilding, naval, marine and offshore indus- tries worldwide. “DeltaLangh has already begun installing similar exhaust gas cleaning systems on our other four vessels. The installations are ex- pected 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 develop- ment process. DeltaLangh was established in June 2014 when Deltamarin Ltd and Oy Langh Ship Ab came together. Scrubber Receives Class Approval (Photo cour tesy of Langh Ship) Volvo Penta is offering factory-built keel-cooled engines for the entire line of marine commercial inboard and sterndrive D4 3.7-liter and D6 5.5-liter engines. The D4/D6 keel-cooled version uses a twin circuit design, with keel coolers for both the high- temperature engine block circuit and low-tempera- ture charge air cooler circuit. “Keel cooling provides unique advan- tages for commercial marine vessels,” said Jens Bering, manager product man- agement for Volvo Penta North America. “By eliminating the need for the seawater pump, these engines are ideal for ves- sels operating in water containing high amounts of sand, silt or other debris that can clog up open-circuit cooling systems. The result is reduced maintenance costs and minimized downtime.” “The D4 and D6 engines are proven workhorses for the most demanding commercial marine applica- tions,” said Bering. “The keel-cooled versions are fully backed by Volvo Penta’s industry-leading war- ranty and service programs.” www.volvopenta.com New Keel Cooling Option Volvo Penta is offering factory-built keel-cooled engines for the line of ma- rine commercial inboard and sterndrive D4 3.7-liter and D6 5.5-liter engines.
