Hull Survey for New Construction Z23 (July 2006) John Finch Chairman

Hull Survey for New Construction Z23 (July 2006)

• John Finch

• Chairman

• IACS expert group on the Hull survey for New Construction

• September 2006

Scope of the presentation:

• To present the IACS UR which has been approved by Council.

• To explain the background to it, how the draft UR was developed and show how industry comments were discussed and incorporated into it.

• The next stages of the groups activities

Items to address:

• Classification survey during newbuilding

• Goal-based standards

• Industry comments so far

• Comments on the scope for the next stage of the group’s task

Introduction:

• At MSC 77 (2003) the Bahamas and Greece proposed IMO’s involvement in developing Goal-based standards (GBS) for shipbuilding. OCIMF made a submission which called for the consistent implementation of classification requirements.

• IACS Council have agreed to include the development 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 be placed on the agenda of MSC 78 in May 2004

• IACS Council agreed to establish an Expert Group for developing Unified Requirements for the survey of New Buildings in December 2003. This group submitted a final draft which incorporated industry comments.

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

Objectives of the expert group

• Develop comprehensive unified requirements for survey – concentrating on the hull structure

• Establish a link between classification and statutory surveys and the draft Goal-based standards being developed at IMO

• Ensure that the Unified Requirement is robust and meets the expectations of industry (taken from the form A)

Background to the Goal-based regulatory framework 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

Goal-based new construction standards application to hull new construction survey…

• Basic Principles – 5

• And requirements developed & applied by Administrations or Classification Societies ….. should be capable of demonstrating compliance with the goal-based standards

• Tier I – Safety Objectives: I-5 Quality of Construction

• Ships should be built in accordance with controlled quality production standards, due care to health & safety of personnel & by using original materials, capable of maintaining their physical & mechanical properties during the expected design life

• Tier II – Functional Requirements: II – 7 Construction quality procedures

• The ship construction quality procedures should include specifications for material manufacturing, assembling, joining and 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 Verification

• 1. The ship compliance with the goal based standards should be verified by means of surveys during construction and at periodic surveys by Administrations or Classification Societies…

• 3. The main construction testing & inspection activities should be witnessed by Surveyors of the … Classification Society … to verify compliance with the goal-based standards & relevant applicable rules

Industry Comments received from:

• Shipbuilders Association of Japan

• Intertanko

• Chinese Shipbuilding Industry

• Intercargo

• EMSA

The make up of UR Z23

• Defines the scope of survey – sub-contractors and shipbuilders 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 for newbuilding activities.

• Requires demonstrable proof of consistency of surveys and describes auditable information.

• Defines the requirements for the Ship Construction File.

Next steps:

• IACS Council has requested the expert group to continue with specific tasks which include:

• develop a UI for initial statutory surveys at new construction
• discuss the issue of coating in its review of statutory issues, consulting with the IACS expert group on coatings
