This paper presents field results and analysis of iceberg towing experiments performed in the Barents and Kara seas in 2016–2017. Influence of oscillations during the towing process is demonstrated. For a wide range of towing speeds, drag force coefficients are determined for icebergs of various sizes and shapes. Simplified formulas for the iceberg towing force are proposed for the stationary mode. Formulas of long-period oscillations are also derived. The possibility of iceberg destruction by the vessel’s circulation in warm water and long-distance iceberg towing is demonstrated.
The possibility of changing an iceberg’s drift trajectory in order to prevent its collision with offshore oil and gas facilities is an important factor for ensuring safe and economic developments in polar offshore regions. This approach is well known and has been used for several decades by oil companies operating offshore Newfoundland and Labrador (Randell et al., 2009). Timely detection (Pavlov et al., 2018) and towing of such giant and unsymmetrical objects as icebergs is associated with a number of specific features. Correct determination requires field tests and proper data analysis.
In order to test the technology of iceberg security under conditions of the Russian Arctic, the Rosneft Oil Company (Moscow, Russia) together with the Arctic and Antarctic Research Institute (AARI, St. Petersburg, Russia) and the Arctic Research Center (Moscow, Russia), performed field iceberg experiments with various technical means in the autumn periods of 2016–2017.
