Summary:
The effect of applying the January 2012 internal draft plus selected Rule amendments of theHarmonised Common Structural Rules (CSR-H) to current tanker and bulk carrier designs has beenassessed.
For this assessment, the designs have not been altered or optimized. CSR-H has been applied onCSR compliant designs, and as such the final effect of applying the CSR-H may be different. Thefinal effect of applying the CSR-H will not become apparent until new designs have been createdwhich balance the distribution of actual scantlings provided against the distribution of Rulerequirements.
Software comparison amongst members on common ships is still ongoing and some differencesstill exist.
This version of the consequence assessment is being released together with the 1 July 2012version of the CSR-H. The reason that the consequence assessment is based on the earlierJanuary 2012 draft version is due to the time necessary for the Societies to update their applicationsoftware and to perform the analyses. The consequence assessment results will be updatedperiodically in order to reflect the newer versions of the rules as they become available and updatedreports will be issued.

1 EXECUTIVE SUMMARY
1.1 Rule referenceJ anuary 2012 internal draft and important Rule amendments in April 2012
1.2 Extent of present Consequence Assessment ReportPrescriptive Assessment: longitudinal structural members in the midship region (Yielding and Buckling)Notes:
Fore and after part and machinery space of the ship and transverse members including bulkheads ofmid-part will be included in future version of the consequence assessment report as well as thefore most and aft most cargo holds/tanks.
Prescriptive fatigue assessment is covered by a separate consequence assessment report. In futureversions of the consequence assessment report fatigue assessment findings will be included in themain report.
Finite Element Assessment: The cargo hold or tank at midship only (Yielding only)Notes:
FE buckling will be included in future version of the consequence assessment report. The fore most and aft most cargo holds/tanks of the ship will be included in future version of the
consequence assessment report. Fine mesh yield assessment and very fine mesh fatigue assessment will be covered in future version
of the consequence assessment report.
1.3 Bulk Carriers Consequence Assessment High Level SummaryPrescriptive AssessmentScantling impact for plating is observed for bulk carriers in comparison with the offered scantlings (detailsgiven in report herein). Most notably the side shell plating in way of the side frame location indicates that theCSR-H is more conservative, mainly due to CSR-H buckling requirement.
In general, the CSR-H prescriptive stiffener results are more conservative than CSR. In comparison with theoffered modulus the scantling impact is more significant than for Oil Tankers. Section modulus requirementincreases have been found for hopper tank and wing tank stiffeners (for yielding and buckling).
Finite Element Yield AssessmentSome areas result in scantling impacts from FE yield assessment (details given in report herein).
Finite Element Buckling AssessmentThe software comparison activity for buckling is in progress. FE buckling results have not been included inthis report version.
1.4 Double Hull Oil Tankers Consequence Assessment High Level
SummaryPrescriptive AssessmentIn general the prescriptive plating assessment shows relatively little scantling impact on the CSR compliantvessels. Keel plating and sheer strake shows scantling results that are more conservative than CSR.
The CSR-H prescriptive stiffener results are more conservative than CSR. However in comparison with theoffered modulus the scantling impact is relative local.
Finite Element Yield AssessmentHarmonised CSR has little scantling impact on the CSR vessels.
Finite Element Buckling AssessmentThe software comparison activity for buckling is in progress and therefore the FE buckling results have notbeen included in this report version.

2 IntroductionA consequence assessment was conducted based upon the J anuary 2012 draft of the Harmonised CommonStructural Rules (CSR-H). A number of important Rule amendments were identified, and these Ruleamendments were incorporated into the software for the present consequence assessment. This report
includes the effect of January 2012 Rules plus these April Rule changes. This compares the newrequirements with the CSR version dated J uly 2010.
This version of the consequence assessment is being released together with the 1 J uly 2012 version of theCSR-H. The reason that the consequence assessment is based on the earlier J anuary 2012 draft version isdue to the time necessary for the Societies to update their application software and to perform the analyses.The consequence assessment results will be updated periodically in order to reflect the newer rules as theybecome available and updated reports will be issued.
The trends and results of the consequence assessment should be considered preliminary andrepresentative at this point in time based on the referenced rule version. It should be noted that thecomparisons will change as the CSR-H are updated based on further project team development or based onIndustry feedback we receive. The results will also change as the Societies update their individual software
packages.
Since this report includes preliminary results based on early drafts of the CSR-H, an overall assessment ofwhether structural areas are governed by the hull girder longitudinal strength, local prescriptive or FEMrequirements has not been made. This work is still ongoing.
It is noted that the entire rule set upon which the results in this consequence assessment report are based issubject to revision. Furthermore specific in progress items that are still under development by the IACSrule developers during the Industry review period have been identified in the Foreword of the CSR-H to helpindustry understand which sections are still being worked on. The following is a list of the in progress itemstogether with the impact on the consequence assessment.

3.2 OilTankers3.2.1 Oil Tankers - VLCC
OT1 VLCC 1 (see Appendix M)
Prescriptive plating: Harmonised CSR has relatively little scantling impact on the CSR vessels. Some strakes on the
longitudinal bulkhead top two strakes do not satisfy CSR-H buckling (buckling factor 1.02 ~1.14)due to design load set OT1-FSM1.
OT2 VLCC 2 (see Appendix N)Prescriptive plating: Harmonised CSR has relatively little scantling impact on the CSR vessels. Increase on inner bottom plating (0.5mm) is observed in comparison with the offered.Prescriptive stiffeners: Some longitudinal stiffeners at inner hull do not satisfy CSR-H requirements. Most main deck
longitudinals do not satisfy CSR-H prescriptive buckling requirements slightly.Finite Element - Yielding Harmonised CSR has little scantling impact on the CSR vessels.
3.2.2 Oil Tankers - Suezmax

3.2.3 Oil Tankers - Aframax
OT5 Aframax 1 (see Appendix Q)Prescriptive plating: Increases on keel plating and sheer strake. Inner bottom, hopper plating and inner hull mid-part
do not meet CSR-H requirements (0.5mm to 1.0mm increase may be needed).Prescriptive stiffeners: Some longitudinal stiffeners at bottom shell, side shell, inner bottom, hopper, inner hull, and
longitudinal bulkhead do not satisfy CSR-H requirements. Main deck longitudinals are failing in buckling (utilisation factor 1~1.23). This is slightly higher
than CSR Buckling (0.87~0.91).Finite Element - Yielding Harmonised CSR has little scantling impact on the CSR vessels.
OT6 Aframax 2 (see Appendix R)Prescriptive plating: On prescriptive plating, Harmonised CSR has relatively little scantling impact on the CSR
vessels.
Bilge plating does not meet the CSR-H buckling requirement.Prescriptive stiffeners: Prescriptive stiffener results from CSR-H are generally more conservative than CSR. However
all the offered scantlings are sufficient to meet CSR-H.
OT7 Aframax 3 (see Appendix S)Prescriptive plating: Keel plating need to be increased by 2.0mm to meet CSR-H requirements. Top strake of inner hull and longitudinal bulkhead is just meeting CSR-H buckling (utilisation
factor 1.02). For the main deck 2.5mm to 3.5mm increase is observed from CSR to CSR-H. The CSR-H
requirements are good match with the offered. The offered thickness for inner bottom will need to be increased by 0.5mm to meet the CSR-H. Thickness increase of 0.5mm for two strakes on the inner hull will be necessary to meet the
CSR-H.Prescriptive stiffeners: Generally the stiffener modulus requirements are higher for CSR-H compared to CSR. In
comparison with the offered there are few locations where increase may be necessary: Fewstiffeners on side shell, main deck.
Majority of the stiffeners on the inner hull and longitudinal bulkhead will need to be increased incomparison to the offered. (mid to upper part).
Main deck longitudinals are failing in buckling (utilisation factor 1.04~1.08). This is higher thanCSR Buckling (0.76~0.83).
OT8 Panamax 1 (see Appendix T)
Prescriptive plating: Side shell plating and sheer strake need to be increased by 0.5mm to meet CSR-H requirements. Bilge plate is failing in buckling (buckling utilisation of 1.87). For the remaining locations all the offered thicknesses are sufficient to meet the CSR-H
requirements.Prescriptive stiffeners: The offered section modulus of the inner hull longitudinals are not meeting the CSR-H section

Numbering systemIn general the strakes and girders are numbered from the centre line outward and from the baseline upward.The stringers are numbered from the upper to the lower.
Stiffener typesThe following identification is used:FB Flat BarBP Bulb PlateIA Inverted AngleT tee section
MaterialsThe following symbols are used:MS Mild Steel of yield stress =235 N/mm
2
H32 High Tensile Steel of yield stress =315 N/mm2
H36 High Tensile Steel of yield stress =355 N/mm2
CSR or CSR-H RequiredThe plating in mm and the stiffener size in cm
3. In the case of required columns, the thickness or section
modulus necessary to comply with the Rules is indicated.
Scantling changeThe incremental change for plating is shown in mm. For plating the following is indicated in the detailedresults in the Appendices:
Difference in net CSRH - CSR in mm Difference in net CSRH offered net thickness in mm
The difference is calculated for Yield results only. The impact of buckling is not indicated in the differencecolumns.
The change for stiffeners is shown as the percentage change in section modulus. For stiffeners the followingis indicated in the detailed results in the Appendices: Percentage difference between CSR and CSRH. Percentage calculated as (CSRH CSR) / CSR. Percentage difference between offered stiffener modulus and CSRH. Percentage calculated as
(CSRH offered) / CSR.The percentages are calculated for Yield results only. The impact of buckling is not indicated in thepercentage columns.
Note: The above two paragraphs with reference to stiffener size, and change for stiffener is tentative only.We will review as we carry out the work to determine whether this is workable.

Finite Element Consequence Assessment plots
Finite element results are presented in a series of plots to show the main structural members in the targetregion (mid tank/hold of the three tank/hold model). In general, the following elements are covered.1. Shell envelope half-hull (bottom and side shell)2. Inner hull/inner bottom (including hopper)
3. Longitudinal bulkhead(s)4. Floors and girders5. Stringers6. Transverse bulkheads (including stool side plate)7. Web frames8. Deck
Items with a usage factor below 0.7 for both rules are to be filtered out. All other results are included.
Two groups of plots for yielding evaluation are presented First group of plots shows the Usage Factor Ratio (CSR-H/CSR) of Cargo Hold Strength Analysis in Mid-
Ship Area. Second group of plots shows the Normalized Yield Usage Factor(CSR-H/CSR-H_Allowable) of Cargo Hold
Strength Analysis in Mid-Ship Area.
