ABSTRACTThe optimum bow shape for an ice-going vessel in ice conditions is different to open water conditions and research about the influence of the bow shape on the structural response due to ice loading and resistance is required. A framework is developed to study the functional relationship between the bow shape and the structural response for ice-going bows in MATLAB. The structural dimensions are optimised by an automatic link to a parametric finite element model in ANSYS Mechanical. Both ...

ABSTRACTShip performance in ice depends on numerous design aspects, such as ensuring adequate thrust, appropriate arrangement of the propellers, as well as a hull designed to reduce the resistance, in both ice and open water. All these efforts require ice resistance estimates. In early design stages, semi-empirical methods represent the most commonly used choice. However, being based on a limited amount of empirical data, these methods are expected to be restricted to ships of similar characteri...

A ship is an investment and built to create revenue. The decision whether the design of a ship is realized or not is therefore strongly affected by the natural obstacles of mission and route. The occurrence of ice along arctic routes is such an obstacle and affects significantly the resistance and the required propulsion power. Advanced simulation environments, such as panel methods or CFD do not exist yet for ice resistance calculations and hence semi-empirical formulations or model tests need ...

Increasing trends in the arctic sea transport lead to the necessity to determine route specific ice conditions to ensure safe vessel transits. In order to achieve this, the comprehensive understanding of ice conditions from the past should be used to predict future trends for arctic sea ice conditions.This paper presents the development of such ice conditions database with the implementation of a satellite data source, which will become a basis for the determination of route specific ice conditi...

The utilization of the Northern Sea Route by commercial ships is an official fact. Since 2009 the number of international cargo vessels using the passage has been increasing, and a continuous raise in these numbers is expected if the route establishes itself as reliable. The route saves vessels approximately two weeks’ time in summer over a route via the Suez channel, but the increase brings concerns, regarding environmental impact, safety, and operability on the route.This paper investigates th...

Ships navigating in ice-covered waters experience local and global ice loads due to ice-hull interaction. The design of a ship with good ice performance requires adequate assessment of these forces. Recently, an increased activity in developing numerical models of ice-hull interaction in level ice has been observed, owed to the increased computational capabilities. However, certain semi-empirical icebreaking patterns inevitably influencing the interaction process have been implemented in the maj...

This paper describes an approach that utilizes a discrete event simulation tool and ice data from a numerical ice prediction model to enable mission-based design of arctic maritime transport systems consisting of a single or multiple arctic cargo ships.For a specific vessel design and route, the developed approach makes it possible to simulate how the transit time varies over time due to both varying ice conditions and stochastic factors such as the weather. Thus, for a given transport scenario ...
