Research on Fatigue Strength of Polar Icebreaker Structures Considering Ice Loads Based on Discrete Ice Element Model

open access: yesJournal of Marine Science and Engineering
Structural safety is of utmost importance for polar icebreakers under both navigation and icebreaking conditions. In this research, the Palmgren–Miner linear cumulative damage theory is employed to evaluate the structural fatigue lifespan of polar ...

An Approach to Determine Optimal Bow Configuration of Polar Ships under Combined Ice and Calm-Water Conditions

open access: yesJournal of Marine Science and Engineering, 2021
Selecting an optimal bow configuration is critical to the preliminary design of polar ships. This paper proposes an approach to determine the optimal bow of polar ships based on present numerical simulation and available published experimental studies ...

Study on icebreaking performance of the Korea icebreaker ARAON in the arctic sea

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2011
A full-scale field trial in ice-covered sea is one of the most important tasks in the design of icebreaking ships. The first Korean icebreaking research vessel ‘ARAON’, after her delivery in late 2009, had a sea ice field trial in the Arctic Sea during ...

Icebreakers for Adults

open access: yesEDIS, 2020
Building rapport is key when creating a team culture. As groups change over time, it is imperative to continually reintroduce and reacclimate new team members to long-standing teammates. Leaders of groups that undergo constant change, like those whose jobs involve volunteers, may find it challenging to find innovative ways to bring people together ...

Child and Youth Engagement in Research, Policymaking, Practice: A Narrative Review of the Evidence

open access: yesChildren &Society, EarlyView.
ABSTRACT A growing body of scholarly literature has analysed the realities of child and youth engagement (CYE) in a range of sectors (including healthcare, education, child welfare/protection) and settings (research, policymaking, practice). Our narrative review of this literature seeks to identify what is known and unknown about how effective and ...

2D numerical modeling of icebreaker advancing in ice-covered water

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2018
This paper presents 2D numerical modeling to calculate ship–ice interactions that occur when an icebreaker advances into ice-covered water. The numerical model calculates repeated icebreaking of an ice plate and removal of small ice floes.

Engaging With Multi‐Level Climate Governance: A Place‐Based Exploration of Public Perceptions of a Local Climate Change Strategy

open access: yesGeo: Geography and Environment, Volume 13, Issue 1, January/June 2026.
Short Abstract Responsibilities for addressing climate change have been distributed across scales of governance, resulting in an increasing number of climate strategies being developed, each grounded within specific sub‐national scales. Drawing upon a relational place‐based framing, we identify tensions within the development and implementation of ...
