15、ion 1: Scope and Conditions of Classification CHAPTER 1 Conditions of Classification SECTION 1 Scope and Conditions of Classification 1 Classification The term classification, as used herein, indicates that a mobile offshore unit, operating on the Norwegian Continental Shelf (NCS), has been designed
16、, constructed, installed and surveyed in compliance with this Guide, applicable existing ABS Rules and Guides or other acceptable standards. General principles and procedures related to classification covered in this Guide are stated in the applicable ABS Rules. The continuance of classification is
17、dependent on the fulfillment of requirements for surveys after construction. According to the Norwegian Petroleum Act, the Owner is fully responsible for verification activities to ensure that operation of units and systems are in compliance with the applicable regulatory requirements. Therefore, th
18、e ultimate responsibility for shutting down operations beyond the limit specified in unit and system design basis does not rest upon the ABS Classification Committee. 3 Class Notation 3.1 ABS N-Notation (1 February 2012) Classification requirements given in this Guide are supplementary to the latest
19、 edition of the ABS Rules and Guides referenced in 1-1/5.1. For the unit to receive the (N) notation, the design is to be verified as being in accordance with the applicable ABS Rules and/or Guides and the additional requirements outlined in this Guide. Additionally, mobile offshore units awarded th
20、e N-notation are to maintain compliance with the applicable standards contained in the latest edition of the PSA Regulations, their associated guidelines and the standards referenced in the AoC Handbook. The design verification undertaken by ABS will determine the units compliance with the technical
21、 requirements contained in the relevant Rules, standards and regulations as applicable. The Class requirements contained herein are to apply to all systems covered by the N-Notation. Additionally, 2-1/Table 3 and Appendix 1 must be applied. Unless the Owner requests additional compliance, drilling o
22、r production facilities will be subject to NORSOK standards. However, in order to verify that safety of the unit is not impaired, ABS is to review the effect of these systems on the surrounding structures, equipment and hazardous area designation. It is recommended that the drilling or production sy
23、stem is classed to avoid any difficulties that the interfaces between plant and vessel may create. Mobile offshore units for operation on the Norwegian Continental Shelf, that have been built to the satisfaction of the ABS Surveyors to the applicable requirements of this Guide, where approved by the
24、 ABS Classification Committee for service for the specified design environmental conditions, may be classed and distinguished in the ABS Record by the symbols A1, followed by the appropriate notation and the (N) notation, for example, A1 Column-Stabilized Drilling Unit (N). The N-Notations for mobil
25、e offshore units and systems are referenced in subsequent Chapters of this Guide. 3.3 Systems Not Built Under Survey Mobile offshore units which have not been built under survey to ABS, but which are submitted for classification, will be subjected to a special classification survey. Where found sati
26、sfactory and thereafter approved by the Committee, they will be classed and distinguished in the Record by the symbols and special notations as described in this Guide, but the mark signifying survey during construction will be omitted. Chapter 1 Conditions of Classification Section 1 Scope and Cond
27、itions of Classification 1-1 ABSGUIDE FOR MOBILE OFFSHORE UNITS OPERATING ON THE NORWEGIAN CONTINENTAL SHELF, N-NOTATION .2013 3 5 Rules for Classification 5.1 Application (1 November 2013) This Guide is intended for use in conjunction with the ABS: Rules for Building and Classing Mobile Offshore Dr
28、illing Units (MODU Rules), Rules for Building and Classing Floating Production Installations (FPI Rules), Rules for Building and Classing Facilities on Offshore Installations (Facilities Rules), Rules for Building and Classing Offshore Support Vessels (OSV Rules) Guide for the Classification of Dril
29、ling Systems (CDS Guide), Guide for Certification of Lifting Appliances, Guide for Building and Classing Mobile Offshore Units Guide for the Class Notation Helicopter Decks and Facilities (HELIDK and HELIDK(SRF) or Other applicable ABS Rules and Guides. The application of this Guide is, in general,
30、based on the contract date for construction between the builder and the prospective Owner. For existing Units, Appendix 3 should be applied. 5.3 Scope (1 November 2013) This Guide covers the safety aspects of the mobile offshore unit operating on NCS, and provides assistance to the Owner for AoC app
31、lication or for a “Request for Consent to Operate” for the following types of mobile offshore units: Accommodation Units Drilling Units Production Storage/Offloading Units (FPSO and FPDSO) Units Storage Offloading Units (for Consent to Operate) Well Intervention Units and the following types of indu
32、strial systems, facilities or equipment: Drilling Systems Production Facilities Helidecks Cranes and Lifting Appliances Note: The AoC scheme is mandatory for all types of mobile units except for the floating storage offloading units, which may be subject to a “Request for Consent to Operate”. Other
33、types of mobile offshore units not included in the above categories are to be treated on an individual basis and be assigned an appropriate classification designation similar to the above format. It is to be noted that the drilling systems and the production facilities are to go through the process
34、of verification for the N-Notation. 5.5 Effective Date of Change of Requirement 5.5.1 Effective Date This Guide and subsequent changes to this Guide are to become effective on the date specified by ABS. In general, the effective date is not less than six months from the date on which the Guide is pu
35、blished and released for its use. However, ABS may bring into force the Guide or individual changes before that date, if necessary or appropriate.

36、AN CONTINENTAL SHELF, N-NOTATION .2013 5.5.2 Implementation of Rule Changes In general, until the effective date, plan approval for designs will follow prior practice unless review under the latest Rules is specifically requested by the party signatory to the application for classification. The date
37、 of “contract for construction” of a mobile offshore unit is the date on which the contract to build the unit is signed between the prospective Owner and the shipbuilder. The date and the construction numbers (i.e., hull numbers) of all the units included in the contract are required to be indicated
38、 on the form, “Application of Request for Classification”. If the signed contract for construction is amended to change the unit type, the date of “contract for construction” of this modified unit, or units, is the date on which the revised contract or a new contract is signed between the Owner, or
39、Owners, and the shipbuilder. 7 Norwegian Regulations and Other Standards While this Guide covers the requirements for the classification of mobile offshore units operating on NCS, the attention of Owners, designers and builders is directed to the requirements of the Norwegian regulations and other s
40、tandards that are over and above the classification requirements. 9 Submission of Plans Subsequent Chapters in this Guide identify requirements for typical mobile offshore units and industrial systems that will be part of the classification and verification process for respective N-Notation. Upon sa
41、tisfactory completion of all of the required engineering and survey processes, ABS will issue the Classification Certificate to the operating mobile offshore unit, including the N-Notation. 9.1 Hull Plans (1 November 2013) Hull plans showing the scantlings, arrangements, and details of the principal
42、 parts of the hull structure of each mobile offshore unit to be built under survey are to be submitted and approved before construction is commenced. These plans are to clearly indicate the scantlings and details of welding, and they are to include such particulars as the design draft and design spe
43、ed. Where provision is to be made for any special type of cargo or for any exceptional conditions of loading, whether in ballast or with cargo, particulars of the weights to be carried and of their distribution are also to be given. 9.3 Machinery Plans Machinery plans showing the boilers, main engin
44、es, reduction gears, etc., also machinery general arrangement, installation and equipment plans as referenced in the applicable Rules, are to be submitted and approved before proceeding with the work. 9.5 System Plans In most cases, manufacturers component and system related drawings, calculations a
45、nd documentation would be required for submittal to substantiate the design of the systems and their equipment. In these cases, upon satisfactory completion of ABS review of the manufacturers submittal, ABS Engineers will issue a review letter. This letter, in conjunction with the submitted package,
46、 will be used and referenced during surveys and subsequently issued reports by attending ABS Surveyors. 11 Abbreviations and Definitions 11.1 Abbreviations (1 November 2013) Abbreviations used in this Guide are as follows: ABS American Bureau of Shipping AoC Acknowledgement of Compliance EEA Europea
