– Environmental risk assessments of shipping in ice covered waters

Alexei Bambulyak is a Country Management Russia at the research company Akvaplan-niva, and a part-time PhD researcher at Norwegian University of Science and Technology (NTNU). Bambulyak has a degree as an engineer-physicist from Petrozavodsk State University, and he is a certified environmental auditor in Russia. He has 20-years' experience in running international capacity building and research projects in environmental and marine shipping issues. Bambulyak is an author of joint reports on environmental studies and regulations in Norway and Russia, marine shipping and oil pollution issues in the Arctic. His PhD research project, called "Environmental risk assessments of shipping in ice covered waters", is an interdisciplinary study focused on oil pollution risks with shipping by the Northern Sea Route. The project is developed in research collaboration between Akvaplan-niva, Norwegian University of Science and Technology and University of Tromsø (Are Sydnes) – the Arctic University of Norway, and involves other stakeholders – research institutes and shipping companies from Norway and Russia.
