API STD 2CCU-2017 pdf download.Offshore Cargo Carrying Units.
1 Scope This standard defines the design, material, manufacture, inspection, repair, maintenance, and marking requirements for offshore cargo carrying units (CCU) and lifting sets, to include dry-goods boxes, baskets, and other skids designed to move equipment and goods offshore with maximum gross weight up to 70,000 kg (1 54,323 lb). Annex A outlines the assessment criteria and parameters for in-service CCU equipment for continued fit-for- purpose applications by users of CCU equipment in conjunction with equipment built to this standard. 2 Normative References The following referenced documents are indispensable for the application of this document.

3 Terms, Definitions, Abbreviations, and Symbols For the purposes of this document, the following terms and definitions apply. 3.1 Terms and Definitions 3.1.1 cargo carrying unit CCU Structural unit designed for repeated use in the transport of goods and equipment to, from, or between fixed and or floating offshore installations, ships, and/or shore-based operations. 3.1.2 enhancement factor A factor accounting for the offshore dynamic loads in the design. 3.1.3 essential non-redundant primary structure Primary members that transfer the resulting cargo load to the crane hook or fork lift (e.g. forming the load path from the payload to the lifting sling); includes, at a minimum: — top and bottom side rails; — top and bottom end rails; — corner posts; — pad eyes; and — forklift pockets. NOTE Other primary structure may also be considered essential and/or non-redundant. 3.1.4 lifting set A flexible, load-carrying member comprised of integrated lifting equipment between the hoisting device and the CCU structure. 3.1.5 lifting test A test in which lifting equipment is subjected to a proof load as prescribed in the applicable section. 3.1.6 maximum gross weight MGW Rating or maximum gross weight of the CCU is the maximum design weight of the container and the cargo. NOTE MGW = tare + payload 3.1.7 nonessential primary structure Structural elements whose main functions are not essential and can be redundant. EXAMPLE Floor plates and protective frame members. Side and roof panels, including corrugated panels, are not considered to be part of the primary structure.
3.1.8 payload <CCU> working load limit P The maximum permissible mass or weight of cargo that is authorized for transport by the CCU. 3.1.9 permanent equipment Equipment that is attached to the CCU that is not considered cargo. 3.1.10 primary structure Load-carrying and supporting frames and load-carrying panels. NOTE Primary structure includes, but is not limited to, the following structural components: — load-carrying and supporting frames; — load-carrying panels; — forklift pockets; — pad eyes; — supports for heavy equipment; — corner/knee brackets. 3.1.11 proof load test <lifting sets> proof test A test performed on a lifting set to a specific multiple of the rated load. 3.1.12 proof load test <CCU> proof test A test performed on a CCU in which the unit’s pad eyes and primary structure is subjected to a specific load. 3.1.13 product specification level PSL Categories of design requirements based on the application. 3.1.14 qualified person A person who, by possession of a recognized degree, certificate, or professional standing, or who, by knowledge, training, or experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter or the work. 3.1.15 secondary structure Components that are not considered “load carrying” for the purposes of the design calculations.
