25ᵗʰ International Conference on Port and Ocean Engineering under Arctic Conditions in Delft Netherlands is now over. Iceman.kz has attended with their contribution into community.
The following works summarising our experience of working with sea ice in the Caspian were presented for discussions during technical sessions:
Early Freeze-up Scenario in the Caspian Sea summarises experience on the earliest freeze-up in the Caspian that occured in 2018 despite of the recent trends with generally warmer winters than observed the end of last century. Operationally provided insights on ice appearences based on many years of observations derived from remote sensing data are extremely valuable for marine laogistics for timely switch between summer and winter fleets utilised in support of Oil and Gas activities in the eastern part of the Caspian.
Marine Operations in Channels through Shallow Ice-Covered Waters discusses future impacts of decreasing water level and operational risks to marine traffic in the shallow northern Caspian. This issue becomes vital for the Eastern part of the sea where expanding Oil and Gas activities take place . Wind driven downsurge events make the situation even more dramatic increasing winter fleet’s downtime to become critical for sustainable operations. This paper is a good example of international collaboration between scientists originating from the countries along the Caspian Coastline. It would not be possible without contribution from professor Bukharitsyn from Astrakhan.
Analysis of Stamukhi Distribution in the Caspian Sea describes the best available knowledge on the unique phenomena that is a specialty for the Caspian. Stamukhi are huge mountains of ice rubble sitting on shallow seabed and pose both navigational hazard for marine transport and exert excess loads on pipelines. Assimilating stamukhi into a single multiparameter database made it possible to derive certain relationships and dependencies that can be used for operational forecasting in operations and for building Basis of Design when engineering pipelines in the region. Interactive tool with free access is available on our website to familiarize with statistics of stamukhi occurence in the region.
Semi-Automatic Ice Floe Detection for Drift Evaluation shows the case of machine learning application in operational ice charting. Several experiments were done to choose algorithms and tune distinct floe detection in images originating from different satellite platforms. With Caspian being further away from the Arctic where polar-orbiting satellites attend the same area more often it is important in the region to consider multi-platform remote sensing data. It makes analysis more sophisticated, but it is worth it once the data flows into our databanks for analysis and building better insights for our Clients.
POAC has once again proven its usefulnes for Iceman.kz to exchange on our technical and scientific development. Learning new trends in the world of sea ice engineering keeps us at the state of the art level of technologies we apply in our daily operations
