GBS for Bulk Carriers and Oil TankersGBS for Bulk Carriers and Oil Tankers

Outcome of GBS at MSC83

• MSC83/5/3 (CG Report):

– Reviewed

• Categorization of ship type (Refer to MSC83/5/16: Korea):

– WG agreed generally

• Linkage bet. GBS and FSA:

– Needed Further Discussion

• Importance of Statistical Data (Refer to MSC83/5/10):

– Premature to make a recommendation

Safety Level ApproachSafety Level Approach （（ SLA)SLA) Work Plan for GBSWork Plan for GBS• Prescriptive and Safety Level

Approach should move forward as integral elements of GBS– Clarification of work to be

done to develop a generic GBS framework

– Identification and compilation of the elements of the framework

– Development of a prioritized plan to close the gaps and provide a unified framework for both prescriptive and safety approach

• Short term plan to MSC86

Outcome of GBS at MSC84

• Generic GBS Framework

• Draft Generic Guidelines for Developing Goal-Based Standards (GBS)

• Prescriptive Approach vs. SLA

• Prescriptive Approach GBS and SLA GBS to be developed in parallel.

• Comparison both GBS in the same field/topics.

• Work Plan*1 for further Development of Goal-Based Standards

• Intercessional (MSC84 – MSC85) • MSC85• Intercessional (MSC85 – MSC 86) • MSC86:

–Finalize Generic Guidelines–Consider long-term implementation of GBS

• Longer Term Consideration (7 sub-items)

*1: Refer to pp.31-32 of MSC 84/24 (Report of MSC84)

Generic GBS FrameworkGeneric GBS Framework

2ND Pilot Project

IACS Contribution

Prior to MSC83

• Contributed by preparing CSR as an example for review by the Pilot Panel (see MSC83/INF.5)

After MSC83 (Refer to Annex 2 of MSC85/5/1)

• Submitted a documentation package to PP (by 31 Mar 2008)

• Participated in PP meeting by answering questions and making a detailed presentation (at 5-6 May 2008)

• Provided Additional information to PP upon PP’s inquiries (by 30 May 2008)

2ND Pilot Project

Report from PP Co-ordinator (MSC85/5/1)

• Guidelines for Verification of Compliance with GBS

– PART A: Verification Process incl. Template of Self-Assessment Summary

– PART B: Information/Documentation Requirements and Evaluation Criteria

• Recommendation regarding Ship Recycling

• Modifications to Tier II Functional Requirements – II.3.3 Ultimate Strength, – Revised Definition of Net Scantlings

(in the footnote of II.3.4 Safety Margins)

Net Scantlings(Footnote of Tier II 3.4 Safety Margins)

Agreed at MSC83

• The net scantlings should provide the structural strength required to sustain the design loads, assuming the structure is in intact condition and accounting for the steel diminution that could be reasonably expected to occur during the life of the vessel due to corrosion and wastage.

PP’s new Proposal

• The net scantlings should …, assuming the structure is in intact condition. However, when assessing fatigue and hull girder global strength, a portion of the corrosion margin may be added to the net scantlings to reflect the material thickness that can reasonably be expected to exist over the design life.

MSC 85/5/6 (Japan) Comments on Net Scantling ConceptMSC 85/5/8 (Korea) Comments on the PP Report

Net Scantlings MSC 85/5/1 PP Report

13 The PP noted the revised definition of net scantlings as approved at MSC 83… … … … … … … …The PP believes this definition needs further clarity as it still contains 　ambiguity over the possible use of corrosion margins in the nominal thickness used for the strength evaluations. … … … …

14 Although the need for the revision of the footnote was agreed by all PP members, a few members pointed out that some wording in the last sentence of the new definition should be further refined to include, for example, the consideration of primary supporting members.

Application

GBS

• In MSC 83/WP.5, Draft New Reg. 3-[10] in SOLAS Ch.II-1 consequentially refers to the def. of bulk carriers in SOLAS Ch. XII

i.e. GBS Bulk Carriers are independent of their cross section and include ore carriers and combination carriers

CSR

• Bulk Carriers (Single Deck, TST and BHT) exclude Ore and Combination Carriers

Thank you for your Attention!!

3. Ships shall be designed and constructed for a specified design life to be safe and environmentally friendly, when properly operated and maintained under the specified operating and environmental conditions, in intact and specified damage conditions, throughout their life.

.1 Safe and environmentally friendly means the ship shall have adequate strength, integrity and stability to minimize the risk of loss of the ship or pollution to the marine environment due to structural failure, including collapse, resulting in flooding or loss of watertight integrity.

.2 Environmentally friendly also includes the ship being constructed of materials for environmentally acceptable recycling.

.3 Safety also includes the ship’s structure, fittings and arrangements providing for safe access, escape, inspection and proper maintenance and facilitating safe operation.

…

Tier I, Goals (Para 3 of draft Regulation 3-[10], see MSC85/5 ANNEX 1)

3. Ships shall be designed and constructed for a specified design life to be safe and environmentally friendly, when properly operated and maintained under the specified operating and environmental conditions, in intact and specified damage conditions, throughout their life.

….4 Specified operating and environmental conditions are

defined by the intended operating area for the ship throughout its life and cover the conditions, including intermediate conditions, arising from cargo and ballast operations in port, waterways and at sea.

.5 Specified design life is the nominal period that the ship is assumed to be exposed to operating and/or environmental conditions and/or the corrosive environment and is used for selecting appropriate ship design parameters.

However, the ship’s actual service life may be longer or shorter depending on the actual operating conditions and maintenance of the ship throughout its life cycle.

Tier I, Goals (Para 3 of draft Regulation 3-[10] (MSC85/5 ANNEX 1)

4 A Ship Construction File with explicit information on how the functional requirements of the Goal-Based New Ship Construction Standards for Bulk Carriers and Oil Tankers have been applied in the ship design and construction shall be provided upon delivery of a new ship and kept on board the ship throughout its service. An additional copy of the Ship Construction File shall be kept ashore by the Company, as defined in regulation IX/1.2. The contents of the Ship Construction File shall be at least equivalent to the framework developed by the Organization.*

* Refer to MSC.1/Circ.[…] (see MSC 85/5 ANNEX 3 ) on Information to be included in a Ship Construction File.”

II.3.4 Ultimate strength

MSC83/WP.5

Ultimate strength calculations should include ultimate hull girder capacity and ultimate strength of plates and stiffeners.

PP’s new Proposal

MSC 85/5/1

Ships should be designed to have adequate ultimate strength. Ultimate strength calculations should include ultimate hull girder capacity and ultimate strength of plates and stiffeners, and be verified for a longitudinal bending moment based on the environmental conditions in II.2.
