UPDATES from the Arctic Environment pilot
Awarded "the best presentation"
Sheng Xu from the Department of Marine Technology was awarded "the best presentation" at the IEEE international conference “The 7th international conference on transportation information and safety”.
The presentation was based on the paper "Investigating the causes of vessel besetting in the ice channel in the Baltic Sea using AIS data and Sentinel imagery", written by Sheng Xu, Ekaterina Kim and Nabil Panchi.
The papers abstract:
Icebreaking assistance in ice-covered waters involves the use of icebreaker(s) to create an ice channel for the assisted vessel(s), which facilitate the vessel(s) navigation in ice conditions. However, assisted vessels that follow the icebreaker may become beset in the ice channel. In April 2021, vessel A navigated in the Baltic Sea with the assistance of icebreakers B and C, during which vessel A experienced three instances of besetting within the ice channel. This research endeavors to examine the underlying causes of vessel besetting within the ice channel by analyzing automatic identification system (AIS) data and ice condition data. The preliminary findings indicate that the primary factors that contributed to that besetting were the severe ice conditions and considerable distances between the icebreaker and the vessel. Evidence to suggest that the channel radius influenced the besetting have not been found, but it is hypothesized that the curvature of the ice channel may have impacted the maneuvering capabilities of icebreaker C in the third beset instance.

New PhD defence from the Artic pilot
New PhD defence from the Artic pilot
Chana Sinsabvaradom from Department of Marine Technology NTNU has successfully defended his PhD thesis Probabilistic modelling of ice-drift and ice loading on fixed and floating offshore structures.
Chana Sinsabvaradom's research is a part of the "NTNU Oceans Pilot Project - Risk, Reliability, and Ice data in Arctic Marine Environment".
His principal area of research focuses on Probabilistic modeling of Ice-drift and Ice Loading on Fixed and Floating Offshore Structures. He performed the uncertainty assessment of the ice load on fixed offshore structures. Furthermore, he has developed mathematical model of the ice drift spectrum to describe the ice drift behavior in the Beaufort Sea during the PhD study.
The results from his work could be contributed the safe design of the offshore structures in the Arctic region.
A day full of highlights
appoints Chana Sinsabvaradom
Knight of the Golden Anchor.
- In the PhD defense date, I feel very appreciated to have a change to pursue the PhD at NTNU and participate in the part of “NTNU Oceans Pilot Project – Risk, Reliability, and Ice data in Arctic Marine Environment” project. It is an amazing day for me to finish my PhD studies and have the Knight of the Golden Anchor ceremony arranged by Professor Jørgen Amdahl, describes Chana after his defence 31st January.

Selected as an Emerging Leader
Selected as an Emerging Leader
Sheng Xu, PhD candidate from the Department of Marine Technology at NTNU has been selected as an Emerging Leader 2023 by Arctic Frontiers.
Sheng’s research is a part of the “NTNU Oceans Pilot Project – Risk, Reliability, and Ice data in Arctic Marine Environment”. His principal area of research focuses on Arctic shipping safety.
He has developed different risk models for Arctic shipping accidents, such as ship besetting in ice and icebreaker-ship collisions, and analyzed the safe distance between icebreaker and ship in escort/convoy operations.
The results from his work could be integrated with route planning to calculate emissions from maritime traffic and contribute to safer operations and mitigate the adverse effects of accidents.
Mentoring program
Emerging Leaders is an early-career and mentoring program in the Arctic for young professionals from the academic, industry and policy sector. The program brings together leaders and mentors, and indigenous, business, and policy representatives, to tell the Arctic stories in an educational journey through Northern Norway.
Sheng Xu will be joining the program this week and will make his own contribution to the Arctic Frontiers conference and will take part in discussions with high level Arctic representatives.
See the presentation of Sheng Xu at Arctic Frontiers webpage.

Sheng Xu awarded with prize for his paper at a prestigious international conference
The researcher at Department of Marine Technology recived the prize at the conference European Safety and Reliability Conference (ESREL), for the paper Impact of the ice navigation experience on the determination of CPT for BN model focusing on Arctic navigation.
The high discrepancies mainly exist in three types of risk factors: ice conditions and ice channel, hydrometeorology factor, ship maneuverability/ship situation. These findings shed light on the Arctic shipping risk factors and imply that there may be knowledge gaps existing between theory study and real ship operation. In addition, the practical way to use the Røed method is put forward.
Sheng Xu won the category Innovation in Foundational issues for Risk Assessment and Management for his paper, within the category PhD Student Award.
This paper was written under the supervision of Ekaterina Kim (Main supervisor) and Stein Haugen (co-supervisor) and funded by “NTNU Oceans Pilot Project-Risk, Reliability, and Ice Data in Arctic Marine Environment”.
