Summary of Amendments of SOLAS II-1/3 -10 (GBS) l Application: Oil tankers & Bulk carriers of 150 m in length and above l Goals: Safe and environmentally friendly Ship design l Structural Requirements : Goals shall be achieved through Structural Requirements of ROs (Class) conforming to GBS Functional Requirements l Ship Construction File (SCF): Information on how the functional requirements have been applied in the ship design and construction to be kept on board Enter into force on 1 Jan. 2012, and apply to ships: 1. building contract on or after 1 July 2016; or 2. keel lay on or after 1 July 2017; or 3. delivery on or after 1 July 2020 5

Goal-Based Ship Construction Standards for Bulk carriers and Oil Tankers Tier I, Goals - SOLAS II-1/3 -10 Para 2 2. 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. 6

Goal-Based Ship Construction Standards for Bulk carriers and Oil Tankers Tier I, Goals - SOLAS II-1/3 -10 Para 2 2. 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. 2 Environmentally friendly also includes the ship being constructed of materials for environmentally acceptable recycling. 2. 3 Safety also includes the ship’s structure, fittings and arrangements providing for safe access, escape, inspection and proper maintenance and facilitating safe operation. 7

Goal-Based Ship Construction Standards for Bulk carriers and Oil Tankers Tier I, Goals - SOLAS II-1/3 -10 Para 2 2. 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. 2. 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. 8

Goal-Based Ship Construction Standards for Bulk carriers and Oil Tankers Tier I, Goals - SOLAS II-1/3 -10 Para 4 4 A Ship Construction File with specific information on how the functional requirements of the Goal-Based 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 and/or ashore* and updated as appropriate throughout the ship’s service. The contents of the Ship Construction File shall, at least, conform to the guidelines developed by the Organization. * 　 * Refer to the Guidelines for the Information to be included in a Ship Construction File (MSC. 1/Circ. 1343). 9

TIRE III – VERIFICATION OF CONFORMITY The rules for the design and construction standards of bulk carriers and oil tankers shall be verified as conforming to the Tier I goals and Tire II functional requirements, based on the guidelines* * Refer to the Guidelines for verification of conformity with goal-based ship construction standards for bulk carriers and oil tankers, adopted by the Organization by Res. MSC. 296(87) 12

Goal-Based Ship Construction Standards for Bulk carriers and Oil Tankers The Guidelines for Verification of Conformity with Goal-Based Ship Construction Standards for Bulk Carrier and Oil Tankers - Res. MSC. 296(87) 1. Documentation Package incl. Self-assessment: • “Rule set” to be verified, all items required by the Guidelines etc. • In Self-assessment Rule Developers (Class) demonstrate that “Rule set” conform to GBS 2. Audit Team: conduct Audit Documentation Package • be established under MSC; and • be composed of 3 to 5 experts nominated by Administrations etc. & selected by the IMO S-G 13

Guidelines for the information to be included in a Ship Construction File - MSC. 1. /Circ. 1343: Ship Construction File (SCF): Aim: to facilitate safe operation, maintenance, survey, repair and emergency measures. 1. to be provided upon delivery of new bulk carriers and oil tankers contracted on or after 1 July 2016. 2. to be kept on board the ship and/or 3. to be kept ashore (i. e. Archive Centers) 4. to be updated as appropriate throughout the updated ship’s life 15

Guidelines for the information to be included in a Ship Construction File - MSC. 1. /Circ. 1343: Examples of information to be included in SCF Information stored on board ship Ø General arrangement, midship section, key construction plans, loading manual, coating technical file Ø Documents to be developed especially to meet the requirements of SCF Guidelines (SCF-specific) such as: l note on design life on midship section l construction quality standard l list of materials used for hull structure Information stored on shore archive Ø yard plans, lines plan, fatigue life calculation 16
