RULES FOR BUILDING AND CLASSING

STEEL VESSELS 2006

NOTICE NO. 3 – April 2006

The following Rule Changes become EFFECTIVE AS OF 1 APRIL 2006.

(See http://www.eagle.org/rules/downloads.html for the consolidated version of the 2006 Steel Vessel Rules, with all Notices and Corrigenda incorporated.)

Notes - The date in the parentheses means the date that the Rule becomes effective for new construction based on the contract date for construction, unless otherwise noted. (See 1-1-4/3.3.)

PART 1 CONDITIONS OF CLASSIFICATION

CHAPTER 1 SCOPE AND CONDITIONS OF CLASSIFICATION

SECTION 3 CLASSIFICATION SYMBOLS AND NOTATIONS

(Add new subsection 1-1-3/21 as follows:)

21 Common Structural Rules for Tanker and Bulk Carriers (1 April 2006) Vessels designed and built to the requirements in Part 5, Chapter 1, Common Structural Rules for Double Hull Oil Tankers, and Part 5, Chapter 3 Common Structural Rules for Single/Double Side Skin Bulk Carriers, will be identified in the Record by the notation CSR, SafeShip – CM.

23 SafeHull Criteria (1 April 2006)

(Renumber the existing subsection 1-1-3/21 to 1-1-3/23 and modify the text as follows:)

Vessels 150 m or more in length whose designs are not within the scope of the Common Structural Rules referred to in 1-1-3/21, and that are designed and built to the requirements in Part 5, Chapter 1 and Part 5, Chapter 3, and vessels designed and built to the requirements in Part 5, Chapter 5 for container carriers will be identified in the Record by the notation SH, SHCM.

PART 1 CONDITIONS OF CLASSIFICATION

CHAPTER 1 SCOPE AND CONDITIONS OF CLASSIFICATION

SECTION 4 RULES FOR CLASSIFICATION

3.3 Implementation of Rule Changes (1-1-4/3.3.1 and 1-1-4/3.3.4 remain unchanged.)

3.3.2 Date of Contract for Construction (1 April 2006)

The date of “contract for construction” of a vessel is the date on which the contract to build the vessel is signed between the prospective owner and the shipbuilder. This date and the construction numbers (i.e. hull numbers) of all the vessels included in the contract are required to be indicated on the form, “Application of Request for Classification”.

3.3.3 Sister Vessels and Optional Vessels (1 April 2006) The date of “contract for construction” as defined 1-1-4/3.3.2 of a series of sister vessels, including specified optional vessels for which the option is ultimately exercised, is the date on which the contract to build the series is signed between the prospective owner and the shipbuilder. A “series of sister vessels” is a series of vessels built to the same approved plans for classification purposes under a single contract for construction, however, sister vessels may have minor design alterations provided such alterations do not affect matters related to classification. The “optional vessels” will be considered part of the same series of sister vessels if the option is exercised not later than one year after the contract to build the series was signed.

7 Alternatives (Delete references for SHR tankers and SHR bulk carriers, as follows:)

7.5 Other Rules (1 April 2006) The Committee will consider hull, equipment or machinery built to the satisfaction of the Surveyors of the Bureau in accordance with the plans that have been approved to the Rules of another recognized classification society with verification of compliance by the Bureau. A special comment will be entered in the Record indicating that classification has incorporated the provisions of this paragraph. In addition, for a container carrier [L ≥ 130 m (427 ft)], the class notation, SHR, will be entered in the Record. The notation, SHR, denotes that the vessel’s scantlings are reviewed based on the requirements in Part 5, Chapter 5, Section 4 for container carriers.

PART 5 SPECIFIC VESSEL TYPES

CHAPTER 1 VESSELS INTENDED TO CARRY OIL IN BULK (150 METERS 9492 FEET) OR MORE IN LENGTH)


CHAPTER 3 VESSELS INTENDED TO CARRY ORE OR BULK CARGOES (150 METERS (492 FEET) OR MORE IN LENGTH)


CHAPTER 4 VESSELS INTENDED TO CARRY ORE OR BULK CARGOES (UNDER 150 METERS (492 FEET) IN LENGTH)

Notice to the application of the Rules

On 1st April 2006, the applicable portions of these rules are to be replaced with the following Common Structural Rules (CSR) developed and agreed upon by the International Association of Classification Societies (IACS):

• The Common Structural Rules for Double Hull Oil Tanker,

Application: For double hull oil tankers of 150m length and upward (See 5-1-1/1.1.1.1 of CSR)

• The Common Structural Rules for Bulk Carriers

Application: For single side skin and double side skin bulk carriers having length L of 90 m or above, which are constructed generally with single deck, double bottom, hopper side tanks and topside tanks and with single or double side skin construction in cargo length area and intended primarily to carry dry cargoes in bulk, excluding ore and combination carriers.

Hybrid bulk carriers, where at least one cargo hold is constructed with hopper tank and topside tank, are covered by the present Rules. The structural strength of members in holds constructed without hopper tank and/or topside tank is to comply with the strength criteria defined in the Rules. (See Chapter 1, Section 1, 1.1.2 of the CSR.)

For vessels 150 m or more in length whose designs are not within the application of the Common Structural Rules referred to in 1-1-3/21 and above, the applicable requirements of Part 5, Chapter 1 Part 5, Chapter 3, or Part 5, Chapter 4 are to comply with. See 1-1-3/23.

The effects of the changes were approved by The ABS Rules Committee at their meeting of 1st December 2005 and 30 January 2006 respectively.

However, the sections in association with the onboard systems will remain unchanged. These relevant sections that will be renumbered in order to fit the CSR organization are as follows:

Current Section No. New Section/Chapter Number “Cargo Oil and Associated Systems” 5-1-7 Part 5, Chapter 1, Section 13


4 ABS RULES FOR BUILDING AND CLASSING STEEL VESSELS . 2006

(Reference to 5-3-7 only) 5-4-3 Part 5, Chapter 3, Subchapter 14

CLASS NOTATIONS The following changes in application of the class notations will be effective for vessels contracted for new construction on or after 1 April 2006:
