API publications are published to facilitate the broad availability of proven, sound engineering and operating practices. These publications are not intended to obviate the need for applying sound engineering judgment regarding when and where these publications should be utilized. The formulation and publication of API publications is not intended in any way to inhibit anyone from using any other practices.
Any manufacturer marking equipment or materials in conformance with the marking requirements of an API standard is solely responsible for complying with all the applicable requirements of that standard.

This specification is based on the experience acquired during the design, construction, operation and maintenance of offshore processing units and permanent facilities, as supplemented with the experience of operating companies with topsides, fixed platforms, floating structures (e.g. TLPs, spars, and the like), and their tendons and risers. Castings in these applications tend to be limited production components, with relatively few replications, and receive more intense scrutiny than routine mass production runs.
Where appropriate, this specification is based on, or reference is made to, international, regional, national and industry standards.
This is a manufacturing specification for the casting itself. It is anticipated that geometric design for both service requirements and casting feasibility will have been agreed collectively between the contractor, manufacturer, and purchaser before this specification is invoked. Attendant issues regarding system reliability, geometric design, incorporation into the overall construction, operation, and maintenance are not addressed here. Those electing to use this specification as a reference for their needed level of performance quality should carefully consider all these attendant issues.
When contractors or manufacturers/suppliers use this specification they should be solely responsible for the quality of work and the attainment of the required design and engineering standards. In particular, for those requirements not specifically covered, the purchaser will expect them to follow those design and engineering practices which will achieve the same level of integrity as reflected in their best production. If in doubt, the contractor or manufacturer/ supplier should, without detracting from his own responsibility, consult the purchaser or its technical advisor.
The purchaser may then negotiate with the authorities concerned with the object of obtaining agreement to follow this specification as closely as possible.
Nothing contained in any API publication is to be construed as granting any right, by implication or otherwise, for the manufacture, sale, or use of any method, apparatus, or product covered by letters patent. Neither should anything contained in the publication be construed as insuring anyone against liability for infringement of letters patent.
This document was produced under API standardization procedures that ensure appropriate notification and participation in the developmental process and is designated as an API standard. Questions concerning the interpretation of the content of this publication or comments and questions concerning the procedures under which this publication was developed should be directed in writing to the Director of Standards, American Petroleum Institute, 200 Massachusetts Avenue, NW, Suite 1100, Washington, DC 20001. Requests for permission to reproduce or translate all or any part of the material published herein should also be addressed to the director.
Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least every five years. A one-time extension of up to two years may be added to this review cycle. Status of the publication can be ascertained from the API Standards Department, telephone (202) 682-8000. A catalog of API publications and materials is published annually by API, 200 Massachusetts Avenue, NW, Suite 1100, Washington, DC 20001.
Suggested revisions are invited and should be submitted to the Standards Department, API, 200 Massachusetts Avenue, NW, Suite 1100, Washington, DC 20001, standards@api.org.

This specification defines the minimum requirements for manufacture, testing, and inspection of carbon and low-alloy steel castings Grades 345 to 586 N/mm2 (50 ksi to 85 ksi) for use in primary steel applications in the fabrication of offshore structures, manufacture of marine mechanical, or riser, tendon, or other equipment intended for application on permanent offshore structures, or for components thereof.
Service categories (A, B, and C), as defined in 4.4, reflect casting geometry and method of incorporation into the overall system. They may also be designated by the user (purchaser) to reflect moderately different but standardized levels of performance.

Manufacture of Structural Steel Castings for Primary Offshore Applications
Castings manufactured to this specification are intended for use in the fabrication of offshore structures, manufacture of critical marine or mechanical or other system components intended for application on permanent offshore structures, or for components used in the construction of offshore tendons, risers and pipelines.
If national and/or local regulations exist in which some of the requirements may be more stringent than in this specification the contractor shall determine which of the requirements are more stringent and which combination of requirements will be acceptable with respect to safety, environmental, economic, and legal aspects. In all cases, the contractor shall inform the purchaser of any deviation from the requirements of this specification which is considered to be necessary in order to comply with national and/or local regulations.
