“…The subject is no longer on the material specimen scale, but the use of a down-scaled hull prototype or weld could be used to represent parts of the ship structure, such as the frame and side hull. Additionally, material subjects could include ice-class steel and the results could be used to inform marine operations in polar regions, which have increased in the last decade following the opening of the Northern Sea Route (NSR) [37][38][39][40][41]. Performance evaluation may use impact testing and sensor applications in either quasi-static or free-fall tests [42].…”

Underwater wet welding (UWW) is applied to repair basic offshore structures, underwater pipelines, water transportation, docks, and port equipment. The underwater wet welding method used in the current research was shield metal arc welding (SMAW), and this was conducted on an A36 steel plate. We investigated the effect of a water temperature of 10 ± 5 °C and different types of water flow (without flow, non-uniform flow with baffle bulkhead, and non-uniform flow without baffle bulkhead). The defects found on the specimen included spattering, irregular surfaces, porosity, and undercutting. A high cooling rate led to the formation of more acicular ferrite (AF) phases in the weld metal area than a slow cooling rate. The microstructure of the heat affected zone (HAZ) area led to the formation of finer and small grains. Values of tensile, impact, and hardness strength were greater with higher cooling rates. The highest tensile strength value was 585.09 MPa, and this occurred with non-uniform flow without a baffle bulkhead. The highest values of absorbed energy and impact strength were 41.9 J and 2.05 J/mm2, respectively, and these occurred with a non-uniform flow without a baffle bulkhead. The greatest hardness values were found with a non-uniform flow without a baffle bulkhead in the weld metal area.

“…There are also many factors and risks deeming the development of the NSR as unprofitable and unsafe, such as higher capital cost of ice-enforced ships and winterization of equipment, variability of sea ice and extreme weather, remoteness, limited satellite communications, price of insurance, and seasonality of routes (Buixade ´Farre ´et al 2014; Gleb and Jin 2021). While global maritime trade occurs predominantly via the Panama and Suez Canals, the projections of sea ice reductions are likely to lead to increased accessibility and navigability of once impassable Arctic sea routes (Hauser et al 2018;Mudryk et al 2021).…”

Numerous narrow marine passages around the world serve as essential gateways for the transportation of goods, the movement of people, and the migration of fish and wildlife. These global gateways facilitate human–nature interactions across distant regions. The socioeconomic and environmental interactions among distant coupled human and natural systems affect the sustainability of global gateways in complex ways. However, the assessment and analysis of global gateways are scattered and fragmented. To fill this knowledge gap, we frame global gateways as telecoupled human and natural systems using an emerging global gateway, the Bering Strait, as a demonstration. We examine how three telecoupling processes (tourism, vessel traffic, and natural resource development) impact and are impacted by the coupled human and natural system of the Bering Strait Region. Given that global gateways share many similarities, our analysis of the Bering Strait Region provides a foundation for the assessment of other telecoupled global gateways.

“…The classification rules are based on the ice thickness in which the ship is intended to navigate: the thicker the ice, the greater the hull reinforcement strength, propeller thickness and steering gear strengthening the ship will need to navigate safely ( 30 ). Ice class is a key factor to ship building premiums and fuel consumption increments ( 31 , 32 ). For convenience of calculation, ice class vessels are assumed to have the same main dimensions except the lightship weight ( 9 ).…”

This paper presents a new framework for economic analysis of marine transportation, where uncertainty is given more attention than in the current research. A new quantitative method combined with the importance ranking method is used to access the uncertainty of evidence and for fusion of evidence from multiple sources. The Bayesian network model is chosen as a tool to convey the uncertainty from one variable to another variable. Finally, with the help of information flow method, key factors are selected for sensitivity analysis. This framework is applied to a case study of maritime transportation from Shanghai to Rotterdam, aiming to investigate the economic potential of the Arctic routes and to explore the possibility of Arctic routes as a substitute for the traditional routes. A well-trained Bayesian network shows that the traditional routes will still dominate marine transportation in the near future. Sensitivity analysis reveals the asymmetric impact of key factors on the plan choice.
