International Conference on Design and Manufacturing of Arctic Structures (DMAS-2019)

The conference provided a forum for networking and knowledge exchange among scientists, researchers, and industry related to manufacturing, welding and joining of Arctic structures, including renewable energy structures. The conference was organized in a framework of ENI CBC EFREA project, which is financed by the European Union, the Russian Federation and the Republic of Finland.

There were 51 attendees in the DMAS conference on Wednesday 2.10.2019. Approximately half of the attendees were from Finnish companies and a half from LUT University and Russian project partners. The conference had good atmosphere and open discussion on the different main topics at the conference.

The main topics were:

Welding of HSS and UHSS for low-temperature condition
Robotic welding and other technology
Wind energy applications for arctic conditions

Dr. Ryabov (CRISM Prometey) gave a presentation titled “Peculiarities of steel requirements for wind power plants.” The main topic was the comparison of different standards used in steel requirements. An author underlined the difficulties in defining the material and structures of wind power in Arctic applications. Dr. Ryabov pointed out that many UHSS are not classified according to the standards for wind structures.

The next was a presentation “Application Possibilities of the Polymer Composite Material Based on Ultra-High Molecular Polyethylene for the Anti-Icing Coatings of Wind Generators Structural Elements” given by Dr. Tatiana Bobkova (CRISM Prometey). She explained the wind turbine anti-icing techniques. She presented the coating processes of developing efficient anti-icing surface for wind turbine blades in low temperatures.

After the first session, participants were invited for lunch to LUT cafeteria and also to attend the poster session.

The poster session featured the following posters:

Assessment and Consideration of Climatic Factors in the Creation of Arctic Wind Power Plants. Presented by junior researcher Inna Bogun from Peter the Great St.Petersburg Polytechnic University.
Features of the structure and properties of cold-resistant steel grades for wind power plants. Prepared by senior engineer Ekaterina Yashina from CRISM Prometey.
Prediction of structural stability and mechanical properties of cold-resistant steel grades. Prepared by Prof. Elena Khlusova from CRISM Prometey.
Study of hyperbaric welding of X70 high strength steel pipes using flux-cored wire. Prepared by Docent Irina Ivanova from Peter the Great St.Petersburg Polytechnic University.
Underwater wet welding and cutting of X70 high strength steel using flux-cored wire. Prepared by Dr. Gennady Levchenko from Peter the Great St.Petersburg Polytechnic University.
A knowledge-based high-strength steels welding distortion estimation method for a multi-robot welding off-line programming and simulation software. Prepared by junior researcher Hannu Lund from LUT University.
