Title: Erkki Ranki: Innovator in Icebreaking Technology
Introduction
Erkki Ranki is a notable inventor based in Helsinki, Finland. He has made significant contributions to the field of watercraft design, particularly focusing on icebreaking technology. With a total of three patents to his name, Ranki's innovations have enhanced the capabilities of vessels operating in icy conditions.
Latest Patents
One of Ranki's latest patents is for a watercraft with improved characteristics for travel in ice. This invention relates to an icebreaker, supply vessel, or cargo vessel that features a hull equipped with a propulsion and steering arrangement. This arrangement includes at least one skeg, which houses a propeller device. The design incorporates two skegs located on either side of the hull's center line, with the propeller device positioned at the stern end of the skeg. Additionally, the skeg is designed with one or more thruster devices that provide a transverse water flow relative to the hull.
Another significant patent is an icebreaking method and icebreaker design. This invention describes a relatively wide vessel that is assisted through an ice field by a narrow-hulled icebreaker. The icebreaker is equipped with two steerable propulsion mechanisms located at opposite ends of the hull. These mechanisms allow the icebreaker to navigate through the ice field at a substantial angle to its keel line, effectively creating a passage wider than the icebreaker's waterline width in a single pass.
