  Konstantinos Kanellakis, Marine Business Development, Group Product Manager Motion & Drives, Schneider Electric presentation during the 2015 GREEN4SEA Forum. The presentation is about the energy efficiency potential of using variable speed drives to run fans and pumps. Usually valves and dampers are used to regulate the flow of air or liquids, which demands more energy than controlling the flow with drives. Two of the most promising solutions are mentioned and a case study of an actual installation and the energy efficiency achieved. All the issues that may arise by the use of drives on ships, like harmonics, electromagnetic interference (EMC) and voltage peaks are analysed.   There are many ways to reduce a ship’s energy consumption, one of which is with the use of variable speed drives. Variable speed drives have a low investment cost and are easy to install, even when the ship is travelling. Another important factor is that it is also one of the solutions with the fastest return-on investment. A variable speed drive is a device which gets power from the network (440V-60Hz) and transforms it so that it will run a motor at the speed we want with the torque our application needs. There are many ...

  Kai Låtun, VP Sales & Marketing, Yara Marine Technologies AS presentation during the 2015 GREEN4SEA Forum. In the presentation “SOx Scrubbers – a profitable investment ?”, Mr Latun looks at under which conditions the profitability of a scrubber investment should be evaluated. He gives some concrete examples of scrubber installations onboard vessels, and illustrates how to calculate paybacktime for a scrubber investment based on realtime conditions. He also reviews the costs of alternative consumables needed during scrubber operations. Yara Marine Technology, used to be known as Green Tech Marine, founded in 2010. Yara Marine Technology has supplied scrubbers since 2012 so it has tens of thousands of operating hours on scrubbers and experience on it. It is also now part of the Yara Group, which is a large Norwegian cooperation with turn over around $15,000,000,000/year and about 10,000 employees.  First of all I would like to say that I’m very happy about the presentation from Lloyds before, because he showed you a chart with green, yellow and red lines, when does it pay to have a scrubber. And being a scrubber supplier, we have very often come across this question. So, we have simply developed a calculator, where you can put ...
