A Shipbuilder's Passion Project Breaks Ice
The OceanHub Interview With Finnish Doctoral Student Kim Salmi
Exploring his own science project that challenges current ice breaking practises in the Ocean Space, Kim Salmi hopes his OceanHub Articles on shipbuilding will create discussion and debate while encouraging innovation.
When Finnish shipbuilder Kim Salmi took on traditional ice-breaking hulls with a new theory, he turned to social media to stoke interest, create a buzz and encourage collaboration. Kim is testing the “upwards bending icebreaking theory,” building a 17-meter steel catamaran as a starting point.
His first LinkedIn post on the project gained momentum, reaching beyond his own connections. To further expand his audience and reach his target audience of inventors, investors and scholars, Kim utilized OceanHub by writing his first Article. He now plans to use the Ocean Space knowledge community as the central hub to update the project’s progress.
"What better way to develop theories and methods than by asking the surrounding professionals and academic community to challenge them?" he said.
Engineering in icebreaking technology has historically played a large role in maritime design and innovation. The evolution from steam-powered icebreaking vessels to today's more modern, multi-use icebreaker fleets has been a result of embracing change. In fact, many of the the break throughs in ice breaking have later been implemented in other fields of shipping.
There has been a renewed interest in ice breaking technology as the number of vessels navigating into the Arctic through the Bering Strait has doubled since 1998, according to the US Coast Guard.
In addition, Kim's home country of Finland, where he has worked on state-of-the-art icebreaker projects, has always been the hub for the lateset icebreaker technology.
As an OceanHub Influencer, Kim is writing knowledge-sharing Articles to further develop his project, what he refers to as a "hobby." He said he is open-minded to input and different technologies he can use. He wishes to collaborate with potential partners, especially in the following fields:
Kim is on OceanHub to build awareness about his project while growing his own influence in shipbuilding.
- Hydrodynamic Innovation
- Power Generation And Propulsion
- Automation and Navigation Controls
Kim is a skilled shipbuilder, materials specialist and doctoral candidate based in Finland. He has worked in shipbuilding since 2008, starting out as a shipyard employee, first as a foreman and then working up to production manager of an icebreaker. He has Master of Science degree in Material Engineering and has worked in logistics, military and diplomatic security before finding his passion in shipbuilding.
Kim recently moved back to Finland after a three-year deployment in Germany and France. Currently, he serves as project manager in the NB Department of Royal Caribbean Cruises Ltd. working within Special Projects and Naval Architecture. Kim is also enrolled for doctoral studies at Aalto University. He has been married for 11 years with two children.

How Did Your Project Come About?
I have been educating myself on the subject over the past 10 years. I had the great privilege of working with some state-of-the-art icebreaker projects in a Helsinki, Finland Shipyard. I learned practical as well as theoretical knowledge from yard and supplier specialists, sucking in their expertise like a sponge. This small cluster has designed and built most of the worlds icebreaking fleet. The opportunity to use the library in Aalto University, containing years of research and development made both in the model ice tank as well as in fullscale, has enriched my understanding of the subject. And, as in my day job, I respect the experience, but whilst doing that, I am not afraid to challenge current practises
What Topics Are You Writing On?
Through the blog, I am bringing out the progress of my private science project - novel icebreaking hull form in boat scale. Whilst following the project process, I will also share my own experiences in shipbuilding, trying to find theme related to the particular process step of the projectI believe that my view points of different aspects of shipbuilding can create debate.. and what is better way to develop theories and methods than having the surrounding professional and/or academic community to challenge them.. I also enjoy to follow, and learn, from side when well argumented visions collide.And of course, as I already published, I am looking for more participants in to this project. A cost effective (cheap) test platform would get new technologies/solutions mounted on it, companies would get inexpensive field testing and as one of the main goals in this type of co-operation, companies as well as academies could benefit on learning from each other. And naturally any success stories during the testing of any of the aspect would also bring positive PR to all the participants
What do you hope to accomplish on OceanHub?
For me OceanHub is a channel for learning and discussions. Blogs are giving possibility to learn basics from wide range of subjects without investing much time. I hope to be able to give something back through my experience. I also hope to gain more interest on my project, while hoping also to be able to promote other new ideas by providing platform for testing. With todays hectic world, one cannot be everywhere and get deep understanding of everything. A channel focused on challenges, technology and news over the common industry enables to keep up on the latest development and accelerates getting new innovations and good practices in use. Thus I see OceanHub as valuable source of information.
What is your thesis?
New upwards bending icebreaking (UBIB-) process and hull form. The development of the process is based on theory which includes studies of sea ice physical properties and precedent studies of icebreaking resistance components, both in full and in model scale. The presented compilation of sea ice theory and ice measurement reports reveal that ice bending strength decreases significantly when the direction of bending is changed from downwards to up- wards. This reduction of strength is strongly related to temperature gradient through the ice thick- ness.
The theory of UBIB processand basic equations for calculating the ice resistance in level ice condi- tions is introduced. The theory relies on existing formulations and data of icebreaking process re- sistance components. New and adapted resistance components are formulated using simple physi- cal approaches. The ice model tests, made with the developed UBIB model, confirmed the basic functioning of the hull type. The tests also introduced new challenges in modelling due to the model ice properties. The behaviour of the model ice in icebreaking velocity changes from brittle to plastic when the bending direction is changed. The theory presented in this thesis predicts over 60% decrease of ice resistance in level ice condi- tions, when new hull type is compared to the current state of the art.
