Coverage. This specification covers intermediate strength steel plates up to 3 in. thick for use in welded tubular construction of offshore platforms, in selected critical portions which must resist impact, plastic fatigue loading, and lameliar tearing. This material is intended for fabrication primarily by cold forming and welding as per API Spec 2B. Welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steel and the intended service. Conversely, the steel should be amenable to fabrication and welding under shipyard and offshore conditions.

Since the primary use of this steel is in tubular joints where portions of the plates will be subject to tension in the thickness direction, the presence of laminations can be extremely damaging. Supplementary Requirement S-1 provides for ultrasonic inspection of the plates by the manufacturer and specifies limits for rejection. If Supplementary Requirement S-1 is not used, it is recommended that the plates be subjected to ultrasonic inspection in the fabrication yard prior to being formed into tubular members. Areas of lamination can be determined and marked to permit the placing of these areas where they will not be subject to through thickness loadings.

The notch toughness requirements specified in Sect 6 are suitable for application above or below water in areas of temperate climate. For areas with lower service temperatures, commensurately lower test temperatures shall be used. Supplementary Requirement S-2 provides for impact tests at temperatures other than specified in Sect. 6.
