I have been involved in ship navigation and related matters since 1996, when I have begun my studies, at Maritime University of Szczecin, in Poland. However my first navigational experience are dated back to 1990, when I became a scout. These days, myself and bunch of friends we were running across forests with compass and map, fortunately not being lost ;)
Then sea navigation came. My first nautical experiences were gained on board refeer vessels, called also "banana vessels", being en route from Carribean to Europe. I spent there almost a year in total. Then I switched from banana to container carriers. Firstly I have been cruising between South America and Europe, then between both Americas, and recently between Asia and South America.
At the same time, I have been working for Maritime University of Szczecin, as an research assistant, I was teaching students and doing my Ph.D. thesis, which was sucessfuly defended in December 2008.
At present I am working at Aalto University, School of Engineering, in Espoo, Finland. I am employed at Department of Applied Mechanic in the Marine Technology Unit.
 
My research field addresses the safety of navigation and maritime traffic risk assessment.
I am especially interested in modern statistical methods and optimization techniques for risk assessment and management. I am focusing on development a holistic risk model with respect to maritime transportation. I have been working on this topic since 2009, after I obtained my Ph.D.
Before that I was validating methods of waterways dimensioning by means of field experiment based method with the use of optoelectronic devices (laser rangefinders).

This page contains my research publications and course materials for students (chapters of student's course books which I am co-author are unfortunately  in Polish only). Only publications which copyrights have not been  transferred to a publisher may be downloaded from here, otherwise a web location is provided.
 
The content of this page is arranged in chronological order, dating back to 2002, when my first conference paper has been published.

EU projects participation
  1. EfficienSea (2009-2012) - 3 year Interreg project aiming at improving safety in the Baltic Sea with focus on the environment and navigation. EfficienSea has a budget of close to 8 million Euro, gathering 16 partners from six countries around the Baltic Sea. Position in the project:  project manager in work package 6.2,  which Aalto University is responsible for, main aim of WP 6.2 is to develop an algorithm for marine traffic risk analysis based on AIS data. Project details and some downloadable materials (presentation from the meetings) you may get from project's web page (www.efficiensea.org).
  2. RescOp (2011-2014) - 3 year project, with The main objective of the project is to enhance Finnish-Russian cooperation regarding risk management to improve maritime safety and reduce trans-boundary environmental risks through research and training. The aim is to develop knowledge based tools for risk management including the main challenges in various environmental conditions throughout the year and taking into account ice conditions. The project aims at strengthening the competitiveness and sustainable economic development of the maritime transport system around the Gulf of Finland. This project aims also to prepare system to train environmental volunteers for oil combating operations in the North West of Russia. Here the possibility to use the voluntary rescue organization as a support organization will be studied.
  3. MIMIC (2011-2014) - the overall aim of the project “Minimizing risks of maritime oil transport by holistic safety and security strategies” (MIMIC) is to combine by an integrative model the information provided so far in earlier projects in a probabilistic framework. This will include traffic growth scenarios with route- and vessel-specific accident probabilities, latest improved biological impacts (e.g. from OILECO and OILRISK projects), and most likely financial consequences in case the accident results in an oil spill. The objective, from management point of view, is to study and compare the effect of different management actions to avoid accidents, giving insight to the cost-effectiveness of these measures. Based on the modeling work, the most effective measures will be identified, and possible new recommendations will be presented. A considerable amount of financial resources is used to disseminate these results to managers, politicians and wider audience to improve the cost efficiency of the money invested to the research and planning activities in this and previous projects. One of the new and specific aims of this project is to view the problem both from the point of private companies (how to create interest for preventive measures) and the society and to try to find ways how society can influence the private activities in most cost effective way to decrease the risks. A totally new element is to link the safety and security issues, where the same actions can support both interests, and same methodology can be used to assess the risks.

  4. CHEMBALTIC (2011-2014) - the main purpose of the project "Risk of maritime transportation of chemicals in the Baltic Sea" (CHEMBALTIC) is to identify the risks related to transportation of dangerous chemicals in the Baltic Sea and to increase the level of environment hazard management. Increasing transportation of dangerous chemicals creates a constant risk for the environment and humans throughout the world. There is a wide and often complex diversity of possible situations involved in incidents which take place during the transport of chemical products. The volume of chemical transportation is mainly related to the strategic position of the areas. In dense traffic areas the concrete actions to prevent possible risk needs to be done. Chemical or dangerous goods transport must be carried out according to regulations that are made to reduce the potential for harm to humans or environment in case of accident or spill.(http://www.merikotka.fi/chembaltic/)
