Removable icebreaker bow is self-powered utilizing Danfoss hybrid innovation
A brand-new Finnish campaign would certainly make it possible for any kind of ice enhanced vessel to be utilized for icebreaking, utilizing a mechanized detachable bow powered by Danfoss Editron.
The Finnish Transport Infrastructure Agency has actually introduced a task that will certainly see the Alfons Håkans AS tugboat Calypso outfitted with the bow as well as operating in the Lake Saimaa location from winter months 2020.
The detachable bow is to be provided by Turku Repair Yard Ltd, which acquired ILS Ship Design as well as Engineering to execute the category style of the bow.
Danfoss Editron’s crossbreed electrical system perseverance the detachable bow with 2 generators, developed as a DC system, as well as 2 propulsion systems. In enhancement, the firm has actually supplied a front supercapacitor to make sure that peak powers can be successfully managed. The Editron software program additionally reduces gas intake as well as provides high effectiveness as the diesel-generators in the DC system can be driven at variable rates. The power strategy as well as propulsion system of the detachable bow has actually been developed to be run from the pusher yank wheelhouse, as well as the equipment can run unmanned.
Jukka Väisänen, Project Operator at Väylä, commented: “Lake Saimaa’s ice is more solid than sea ice and can reach up to 80 cm thick. Developing this innovative design concept for the removable bow and equipping it with its own propulsion system means that we will achieve savings in capital costs, as we will charter the pusher for only part of the year. We are also expecting to see savings in fuel consumption thanks to the hybrid propulsion system.”
Kari Savolainen, Project Manager at Danfoss Editron, included: “Our headquarters are in Lappeenranta, so we can see first-hand how harsh winter conditions directly impact shipping transport. This new kind of removable bow will make the whole industry more efficient and sustainable, as it enables virtually any kind of tug to become an ice-breaker ship. Our Editron system is easily adaptable for future optimizations and can be converted to a fully-electric system if needed.”
