本文中使用的术语“分类”表示海上设施的设计、建造、安装和测量符合这些规则。分类的持续性取决于施工后测量要求的满足情况。分类过程包括a）为结构、材料、设备和机械的设计和施工制定规则、指南、标准和其他标准，b）在施工期间和之后审查设计和测量，以验证是否符合此类规则、指南、标准或其他标准，以及c）当此类合规性得到验证时，类别的转让和注册。 这些规则和标准由海洋局工作人员制定，并由海洋工程师、海军建筑师、海洋工程师、建造师、钢铁制造商以及其他与全球海洋行业相关的技术、操作和科学人员组成的委员会通过。理论研究和开发、已建立的工程学科以及令人满意的服务经验被用于其开发和发布。在制定规则和标准时，该局及其委员会只能根据这些理论和实践考虑采取行动。

The term classification, as used herein, indicates that an offshore installation has been designed, constructed, installed and surveyed in compliance with these Rules. The continuance of classification is dependent on the fulfillment of requirements for surveys after construction. The Classification process consists of a) the development of Rules, Guides, standards and other criteria for the design and construction of structures, for materials, equipment and machinery, b) the review of design and survey during and after construction to verify compliance with such Rules, Guides, standards or other criteria, and c) the assignment and registration of class when such compliance has been verified. The Rules and standards are developed by Bureau staff and passed upon by committees made up of offshore engineers, naval architects, marine engineers, constructors, steel makers and by other technical, operating and scientific personnel associated with the worldwide offshore industry. Theoretical research and development, established engineering disciplines, as well as satisfactory services experience are utilized in their development and promulgation. The Bureau and its committees can act only upon such theoretical and practical considerations in developing Rules and standards.
