Scope of the presentation:

To present the IACS UR which has beenapproved by Council.

To explain the background to it, how the

draft UR was developed and show howindustry comments were discussed andincorporated into it.

The next stages of the groups activities

Goal-based standards

Industry comments so far

Comments on the scope for the next stage ofthe groups task

Introduction:

At MSC 77 (2003) the Bahamas and Greece proposed

IMOs involvement in developing Goal-basedstandards (GBS) for shipbuilding. OCIMF made a

submission which called for the consistentimplementation of classification requirements.

IACS Council have agreed to include thedevelopment of GBS for shipbuilding into its

strategic plan

a joint submission IACS/Bahamas/Greece was made to MSC.

MSC agreed that a new work programme item to beplaced on the agenda of MSC 78 in May 2004

IACS Council agreed to establish an Expert Group for

developing Unified Requirements for the survey ofNew Buildings in December 2003. This groupsubmitted a final draft which incorporated industrycomments.

Council approved UR Z23 in July 2006 and issued itin August for implementation from 1 Jan 2008.


5/11

Objectives of the expert group

Develop comprehensive unifiedrequirements for survey concentrating onthe hull structure

Establish a link between classification and

statutory surveys and the draft Goal-basedstandards being developed at IMO

Ensure that the Unified Requirement isrobust and meets the expectations ofindustry (taken from the form A)

Background to the Goal-based regulatoryframework and the links with UR Z23

The tiered pyramid

Basic principles

The tiers

Tier I safety objectives

Tier II functional requirements

Tier III - verification of compliance criteria

Summary


7/11

Goal-based new construction standardsapplication to hull new construction survey

Basic Principles 5

And requirements developed & applied by Administrations orClassification Societies .. should be capable ofdemonstrating compliance with the goal-based standards

Tier I Safety Objectives: I-5 Quality of Construction

Ships should be built in accordance with controlled qualityproduction standards, due care to health & safety of personnel& by using original materials, capable of maintaining theirphysical & mechanical properties during the expected designlife

Tier II Functional Requirements: II 7 Construction quality

procedures

The ship construction quality procedures should includespecifications for material manufacturing, assembling, joiningand welding procedures, steel surface preparation and coating

Goal-based new construction standards

application to hull new construction survey

Tier III Verification of Compliance Criteria

III - 1 Design

5. Development of Ship Construction File

III 2 Verification1. The ship compliance with the goal basedstandards should be verified by means of surveysduring construction and at periodic surveys byAdministrations or Classification Societies

3. The main construction testing & inspectionactivities should be witnessed by Surveyors of the Classification Society to verify compliance withthe goal-based standards & relevant applicable rules

10/11

The make up of UR Z23

Defines the scope of survey sub-contractors andshipbuilders to be treated alike.

Assessment of the construction facilities required.

Provides a list of surveyable items for the hull

structure. Requires newbuilding survey planning.

Requires on the examination and test plan fornewbuilding activities.

Requires demonstrable proof of consistency ofsurveys and describes auditable information.

Defines the requirements for the Ship ConstructionFile.


11/11

Next steps:

IACS Council has requested the expertgroup to continue with specific taskswhich include:

develop a UI for initial statutory surveysat new construction

discuss the issue of coating in its reviewof statutory issues, consulting with theIACS expert group on coatings
