45、ns of Classification 1 Classification The requirements for conditions of Classification for entire drilling units and offshore structures are contained in the ABS Rules for Conditions of Classification Offshore Units and Structures (Part 1). Additional requirements specific to a drilling system, its
46、 subsystems, equipment or components are contained in this Guide. 1.1 Process The term Classification, as used herein, indicates that drilling systems, subsystems, equipment, and/or components have been designed, constructed, installed, and surveyed in compliance with this Guide, in conjunction with
47、 other applicable ABS Rules and Guides, codes and standards as referenced therein, and applicable national regulations. The continuance of Classification is dependent on the fulfillment of requirements for surveys after construction. The Classification process consists of: a) The development of Rule
48、s, Guides, standards and other criteria for the design, construction, installation and maintenance of drilling systems, subsystems, equipment, and/or components; b) The review of the design and survey during and after construction to verify compliance with such Rules, Guides, standards or other crit
49、eria; c) The assignment and registration of Class when such compliance has been verified, and; d) The issuance of a renewable Classification certificate, with annual endorsements, valid for five (5) years. The Rules, Guides and standards are, in general, developed by the International Association of Classification Societies and ABS staff and passed upon by committees made up of naval architects, ocean and marine engineers, shipbuilders, engine builders, steel makers, process engineers and by other technica
