Fatigue Design Assessment of Ship Structures Induced by Ice Loading -An introduction to the ShipRight FDA ICE Procedure

摘要

As part of the ShipRight design and construction procedures, Lloyd's Register has recently developed a Fatigue Design Assessment procedure, ShipRight FDA ICE, to assess fatigue damage of ship structure induced by ice loads for ships navigating in ice covered regions. The paper outlines the ShipRight FDA ICE procedure including the determination of trading routes in ice regions, ice loads and impact frequencies, structural stresses, fatigue performance at low temperatures, fatigue damage and acceptance criteria. The paper provides an overview of the assessment methodology and highlights the key elements with case studies.
