A Bayesian network model for estimating the combined risk in Northeast Passage escort operations
Xu, Sheng; Kim, Ekaterina (Journal article; Peer reviewed, 2025)Escort and convoy operations are commonly employed and highly effective strategies in the Arctic, particularly when ship navigating independently becomes challenging due to adverse ice conditions. Nonetheless, these ... -
A Bayesian network risk model for predicting ship besetting in ice during convoy operations along the Northern Sea Route
Xu, Sheng; Kim, Ekaterina; Haugen, Stein; Zhang, Mingyang (Journal article; Peer reviewed, 2022)To facilitate shipping in ice and to meet the increasing requirements of icebreaker services, convoy operations are the most effective alternative. However, convoy operations are among the most dangerous operations as they ... -
Do vessels remain within their operational limitations in ice? Analyzing the risks of vessels operating in the Kara Sea region using POLARIS
Panchi, Nabil; Kim, Ekaterina; Xu, Sheng (Chapter, 2020)This study investigates whether the vessels remain within their operational limitations in ice using the risk index calculated based on the Polar Operational Limitations Assessment Risk Indexing System (POLARIS) - an ... -
Hybrid causal logic model for estimating the probability of an icebreaker–ship collision in an ice channel during an escort operation along the Northeast Passage
Xu, Sheng; Kim, Ekaterina (Peer reviewed; Journal article, 2023)Under severe Arctic ice conditions, escort operations are the most efficient methods for facilitating shipping. Nevertheless, escort operations are among the most dangerous operations, as they may result in icebreaker–ship ... -
Integrating Software FMEA and STPA to Develop a Bayesian Network-Based Software Risk Model for Autonomous Ships
Yang, Xue; Zhu, Yawei; Zhou, Tao; Xu, Sheng; Zhang, Wenjun; Zhou, Xiangyu; Meng, Xiangkun (Peer reviewed; Journal article, 2023)The autonomous shipping industry is increasingly focusing on enhancing the safety and reliability of software-based systems. Conducting a risk assessment is a requirement for demonstrating the safety equivalence of autonomous ... -
A Novel Data-Driven Prediction Framework for Ship Navigation Accidents in the Arctic Region
Yang, Xue; Zhing, Jingkai; Zhang, Wenjun; Xu, Sheng; Meng, Xiangkun (Peer reviewed; Journal article, 2023)Arctic navigation faces numerous challenges, including uncertain ice conditions, rapid weather changes, limited communication capabilities, and lack of search and rescue infrastructure, all of which increase the risks ... -
On Statistical Features of Ice Loads on Fixed and Floating Offshore Structures
Sinsabvarodom, Chana; Leira, Bernt Johan; Høyland, Knut Vilhelm; Næss, Arvid; Samardžija, Ilija; Chai, Wei; Komonjinda, Siramas; Chaichana, Chatchawan; Xu, Sheng (Peer reviewed; Journal article, 2024) -
Review and comparison of existing risk analysis models applied within shipping in ice-covered waters
Xu, Sheng; Kim, Ekaterina; Haugen, Stein (Peer reviewed; Journal article, 2021)With the changing climate and declining extent of sea ice, the activities in the Arctic region have become increasing significantly. Compared to the environments with ice-free waters, the harsh environment in the Arctic ... -
Shipping Safety in the Arctic - Contributions to the understanding of shipping risk during escort and convoy operations
Xu, Sheng (Doctoral theses at NTNU;2024:200, Doctoral thesis, 2024)The decline in Arctic ice extent has drawn increasing attention to Arctic shipping. In comparison to traditional routes, Arctic routes offer substantial advantages, particularly in terms of time efficiency and cost ...
