... Ice-structure interaction (ISI) is a complex process, which requires a thorough understanding of the underlying physics to ensure safe operations in the ice-covered regions. Application of discrete element method (DEM) to compute ice loads on structures is a widely accepted approach, where...

... Abstract This paper presents operational experience and ice measurement results from Finnish Icebreaker Polaris propulsion system. Icebreaker Polaris applies a novel three propulsion unit concept. During the shipbuilding period an extensive ice load measurement system was installed on two...

.... In Arctic area, the ice load is the main factor of environmental load acting on Arctic vessel. The ice load is increased with the enlargement of vessel. The largest Arctic commercial vessel was built by DSME in 2016. The vessel was delivered after completion of ice trial in March 2017. The size of Arctic...

... Abstract Approaches are presented in this paper for estimating the global mooring loads and response of a semi-submersible drilling rig, as a result of pack ice loading. The focus is on loading events from pack ice conditions relevant to the Grand Banks, where the pack ice typically consists...

... Abstract Wind turbine towers are being planned in ice covered regions subject to pressure ridges (e.g. the Great Lakes). Conical collars are often employed to reduce ice loads from level ice and their associated dynamics. For level ice, downward breaking cones have some advantages...

... Abstract Different kinds of offshore structures are designed and built to resist the scenarios of the arctic environment. This paper focuses on different ice load scenarios and the challenges for fixed offshore structures. Model test methods will be presented to assess the suitability...

... properly scaled model ice (700 kPa of flexural strength in full scale) in order to simulate ice failure appropriately. Ice loads were not directly measured but estimated based on the thrusters’ response. Video analysis is introduced and some observations are described. Test results for a few cases...

... size). The yearly encounter frequency is first estimated for these ice features for the site of interest. The ice loads are then determined for each of simulated interaction event occurring over the model timespan, using the deterministic load formulations. By simulating a large number of years of ice...

... Abstract This paper presents the results and insights gained from numerical simulations of the response of FRP laminate plates to ice loads. These models were motivated and supported by previous related research in the form of full-scale field trials, ice-tank model tests, and FRP laminates...

... Abstract In ISO19906 (2010) (Arctic Offshore Structures) specific algorithms are provided for level ice loads on sloping structures; they are based on the separate work of Ralston and Croasdale. These methods were developed decades ago and comparisons with full scale data, especially from...

... of a Minimal Facilities Platform or is also known as a Conductor Supported Wellhead Platform (CSWP) in the North Caspian Sea region and specifically focuses on the design optimization of the substructure due to ice loads. The CSWP has not been used in the cold climate regions before. The intention...

... throughout the year. Ice load analysis is needed for semi-submersible rigs operating in ice prone regions to determine ice strengthening requirements. Ship-based ice class rules can be considered for the design loads of the pontoons in transit conditions, but there is no standardized methodology...

... every 10 years given ice management. While ice strength data for sea ice loads is often presented in terms of upper limit strengths based on the assumption that there are large numbers of interactions per year, a probabilistic approach that explicitly considers the frequency of events is more...

...) is a new approach to solve complex problems and transform the GPU into a massively parallel processor. The present study applies the GPGPU technology to a Monte-Carlo simulation, used for a sea ice load application. The objective of this study is to measure the performance of the GPU using CUDA...

... Abstract The prediction of practical ice loads for ships operating in ice-covered waters is fundamental to the calibration of ice class requirements and improvement of Polar ship structural design. Data collected from full-scale instrumentation campaigns is highly valuable, not only...
