ABS Seminar on Baltic Ice Class

ABS Case Study by ABS Guide on Non-Linear FEAABS Seminar on Baltic Ice Class

Presentation ContentIntroduction of ABS Non-Linear AnalysisCase Study I by ABS GuideCase Study II by ABS GuideCase Study III - ABS Proposal to FMAReduced FMA side shell plating

Extent of FEA ModelLongitudinal Direction- Minimum 3 web spacings w/Half web spacing on fore and aftVertical Direction- To be extended two horizontal stringers including Ice belt zoneIce load applies to one single longitudinalHorizontal Direction- Includes the inner skin

FE Model Extent

Mesh SizeRecommend to divide side shell longitudinal web in at least three elementsFlange can be modeled by shell element or a beam elementMesh of Side shell, web frame and inner skin are the same size of the mesh in longitudinal web plateStructures away from ice belt may be of a coarser meshBrackets should be fine enough to carry at least three elements

Mesh of Side longis and bkt at connection to web frame

BoundaryTop and Bottom planes-allow x-dir rotationForward and Aft planes-symmetric condition

FEM SolutionBasic approach is to apply load incrementally Load increment should be sufficiently fine to insure the accuracy of the prediction10 to 20 steps to loading until reach Max line load required by FMA Guide10 to 20 steps to unloading until line load is zero

FEM SolutionConvergence Affects the accuracy and overall efficient in No-linear analysisThere are no universally accepted criteriaABS accepts the criteria in MSC HandbookError tolerance for Displacement is less than 10-3Error tolerance for loads is less than 10-3Error tolerance for energy is less than 10-7Load step is assumed to converge when all three tolerances are metIF the solution does not converge, increase the number of load steps

Acceptance Criteria If the plastic deformation for the proposed structure is equal or smaller than for the Rule(FSICR) structure, the scantlings of the proposed structure is considered acceptable

The Non-linear FEM Analysis for 160K Suezmax TankerBy Applying ABS Guidance Notes on Non-Linear FEA of Side Structures Subject to Ice Loads CASE I

ObjectiveVerify the side structure in accordance with ABS procedure in Guidance Notes on Non-Linear Finite Element Analysis of Side Structures Subject to Ice Loads Compare the plastic deformation between rule structure (Sp=450mm, 350mm) and proposed structure (Sp=850mm) for IC,IB and IA ice class by Tentative Note for Application of Direct Calculation Methods for longitudinally Framed Hull Structure issued by FMA on 30 June 2003
