SP21507 Standard Practice for Sandwich Plate Composite Repair of Steel Structures
Both onshore storage tanks and offshore/marine vessels and units (such as floating production storage and offloading (FPSO) units, Floating Storage and Offloading (FSO) units) for oil and gas drilling, production, and transportation generally experience very corrosive environments. Severe corrosion to the structures is frequently required to be repaired for restoration of the structural strength and the tightness for safety requirement from regulatory. Conventionally crop-and-replace method and welding repairs are used in the oil and gas industry and allowed from regulatory requirements. However, these repairs are considered as a hot work repair method. Once the hot work repair is arranged, it is required that the subject tank/location and adjacent tanks/structures be in a gas free condition for compliance with safety requirements. This may cause a significant impact on the continuous operation of the units. Thus, adhesively bonded sandwich composite repairs to the damaged structure would be generally preferred for favorite considerations of safety and continuous operation as the repairs can be done without cutting and replacement of steel place and only one side access is needed during the repair. With the increased use of composites in repairs for maritime vessel and oil / gas structures, a standard practice is needed for a unified industry standard for all parties of the repair technology. This standard practice is to set out requirement on the Sandwich Plate Composite Repair of Steel Structures for predicted repair life.

SP21590 - Internal Corrosion Management Utilizing a Barrier and Integrity Operating Window Approach
The Standard Practice outlines a corrosion management system in line with industry procedures for internal process streams. The system described is based upon process safety and asset integrity control framework utilizing barrier management and Integrity Operating Window (IOW) control. The process is based on definition and requirements which focus corrosion management on the quality of control measures (quality of barriers) in place to control a failure mode. Where resistant materials are selected against a failure mode, its application limits require control on the safe operating limits identified as IOW which comes with controls on composition and operating conditions.

GUIDE 21552 - Corrosion Considerations for Selection of Rock Bolts
The present document will discuss the principal corrosion mechanisms governing the degradation of rock bolts. An explanation for mechanism will be provided, along with a discussion on the factors that may impact the rate of degradation. The mechanistic discussion will be linked to corrosion mitigation strategies that may include material selection, coatings, cathodic protection, etc. The document will provide a brief overview of the required testing needed to characterize the service environment and a general decision-making guide that will help pair up the right rock bolt with the right corrosion mitigation strategy for a given design life.

GUIDE21614 Standard Practice for Improving the Precision of Dry Coating Thickness Measurements on Ferrous and Non-ferrous Metal Substrates Using Continuous Read/Scanning Technology
Statistical analysis of data (based on research and a Technical Paper presented by Jeff O’Dell, Vision Point at the SSPC 2017 National Conference) suggests that greater precision of dry film thickness (DFT) measurements can be achieved by obtaining a greater population of measurements over a larger area using the scanning method over the traditional “place & remove probe” frequency described in Section 8 of the current version of the SSPC-PA 2 standard. Also, scanning technology enables an operator to collect a greater number of DFT measurements in a shorter time frame than the traditional “place & remove probe” method. Due to the increased number of measurements being collected, better indication of the sample mean can be obtained through increased precision.
