... Abstract Arctic offshore structures are subject to combined wave-ice actions. However, the underlying mechanisms governing the interaction between waves ice and these structures remain inadequately understood. Performing well-controlled laboratory experiments is a fundamental approach...

... to the case of a medium icebreaker. The emissions predictions are based on a model of ship resistance and propulsion in ice and open water, and they constitute an essential part of a general ship performance model. Route optimization can be informed by such ship performance models in combination with routing...

... and resource constraints, the similar texture of different ice images is the major challenge for iceberg identification, which may lead to false navigation for the ship controlling system. The main purpose of this paper is to generate accurate pixel-level iceberg image segmentation and prediction under poor...

... Abstract With climate change, the ice cover in the Arctic and subArctic regions is likely to change relatively quickly. The Baltic Sea is a region with much maritime traffic and meanwhile some parts are covered by ice during wintertime. Icebreakers are usually needed in this region to assist...

... Abstract Sea ice reporting and ice charts are a necessary simplification of highly variable sea ice conditions over large areas. Ice conditions are typically shown using egg codes. These codes can be used to determine an equivalent ice thickness as a method for calculating a ship’s ice...

... Abstract This study presents an elastoplastic material model with a pressure and rate dependent yield criterion for freshwater polycrystalline ice, implemented to simulate the structural damage in a full-scale AA5083-H116 aluminium panel subject to ice impact load in a drop test. The proposed...

... Abstract The performance of ships going through ice-covered water is a main focus of the design of such ships. Estimation of ships’ ice-going performance has been a challenging task for decades due to the complexity in the modelling of ship-ice interaction process. To date, empirical formulae...

... Abstract A study is performed to establish and enlarge the knowledge on the factors influencing the friction between ice and ship hulls. A set of experimental friction tests with a newly designed testing apparatus with computer controlled stroke, speed and acceleration is conducted. The testing...

... Abstract In this research, an experimental method was used to evaluate the effects of a novel digital Decision Support System (DSS) for maritime ice management operations. This was done using a marine bridge simulator to determine whether the use of this technology can improve ice management...

... Abstract OSIS-IHI (Ocean Structure Interaction Simulator – Ice-Hull Interaction) is a ship maneuvering in ice modeling software developed at OCRE for a marine simulator and ship performance assessment applications. A series of OSIS-IHI simulations is conducted to explain the maneuvering...

... Abstract This paper provides a general review of available models used in the NRC-OCRE (National Research Council – Ocean, Coastal and River Engineering) that could be used to support the assessment of a ship’s performance in ice conditions. The models were separated into three main categories...

... Abstract This study investigates variability of ships’ operational limitations for ice conditions in view of national rules and international recommendations (the Rules for Navigation in the Water Area of the Northern Sea Route and the International Maritime Organization Recommendations...

... 09 01 2009 Several offshore platforms and artificial islands will be constructed in the Caspian Sea for the exploration and production of oil. In some cases, vulnerable structures can be protected against severe ice loading using rock mound barriers. These barriers will be constructed...

... 05 01 2009 Several techniques have already been proposed to determine ice adhesion strength. This study made a critical review of the existing methods and proposed three other techniques for ice/substrate systems, where the latter techniques have already been used to other adhesive...
