Title: Tuomas Herranen - Innovator in Marine Vessel Technology
Introduction
Tuomas Herranen is an accomplished inventor based in Helsinki, Finland. He currently works at ABB Oy, where he focuses on developing innovative solutions for marine vessels. Despite having no granted patents to his name, Herranen has made significant contributions through his latest patent applications.
Latest Patent Applications
Herranen's recent patent applications include two notable inventions. The first is a "Method and Arrangement for Sealing a Propeller Shaft of a Marine Vessel." This invention outlines a method and arrangement for sealing a propeller shaft, which is rotatably supported with a bearing arrangement inside a pod suspended at the hull of the marine vessel. The design features at least two seal rings spaced apart to create a lubricant seal chamber, along with a lubrication arrangement for conducting lubricant to and from the bearing arrangement.
The second application is for a "Propulsion Unit for a Marine Vessel." This propulsion unit comprises a shell structure, a shaft rotatably coupled to a propulsion motor inside the shell, and a propeller coupled to the shaft outside the shell structure. The invention includes a shaft seal arrangement that engages the shaft, creating a seal chamber between adjacent seal lips. Additionally, a lubrication arrangement circulates lubricant through the seal chamber, with a heat exchanger designed to transfer heat from the lubricant to the environment outside the shell structure.
