IMO GBS – MSC 87/26/Add.1

Applicable to oil tankers and bulk carriers For which the contract is placed on or after 1 July 2016

In the absence of a building contract, the keels of which are laid or which are at the similar stage of construction on or after 1 July 2017

Regardless of the contract or keel laying date, the delivery which is on or after 1 July 2020

GBS Verification

Classification Society submission to IMO by the end of 2013

IMO Audit Team verification review by 16 May 2016

Application 1 July 2016

Compliance required for SOLAS certification

31 Dec 2013 16 May 2016 1 July 2016

GBS Functional Requirements

Structural and residual strength Fatigue life Corrosion protection Structural redundancy Watertight and weather tight integrity Human element conditions Design transparency Construction quality procedures Survey during construction In-service survey and maintenance Structural accessibility Recycling

Verification with Conformity with GBS

Submission of the harmonized version of the CSR

GBS timeline drives the CSR harmonization schedule

10

GBS Impact on CSR

Gaps to be filled for compliance with GBS New criteria in the harmonized CSR

Consequence assessment to determine the impact

Impact from the verification process Time lag between harmonized Rules and the

completion of the verification process

IMO involvement in the Rule Change process Small group of individuals in the audit team

Conclusion

CSR and GBS major steps in the evolution of structural requirements

‘Rules for Rules’

Success will depend on implementation
