ISO/TC 67/SC 4/WG 2 - Drilling well control equipment

ISO 13354:2014 specifies requirements for the selection of the diverter equipment for rigs used to drill shallow-gas-bearing formations. It covers both onshore and offshore drilling operations, and considers also the auxiliary equipment associated with floating rigs. The specified requirements concern the following diverter equipment: annular sealing devices; vent outlets; diverter valves; diverter piping. ISO 13554:2014 highlights the concerns associated with the selection of a marine floating drilling support. It covers safety issues concerning key rig equipment, and important steps of action required prior to starting the drilling operations. It provides only general guidelines regarding the response to be given to a shallow-gas flow.

ISO/TR 13624-2:2009 pertains to mobile offshore drilling units that employ a subsea BOP stack deployed at the seafloor. It is intended that the drilling riser analysis methodologies discussed in this part of ISO 13624 be used and interpreted in the context of ISO 13624-1.

ISO 13624-1:2009 pertains to the design, selection, operation and maintenance of marine riser systems for floating drilling operations. Its purpose is to serve as a reference for designers, for those who select system components, and for those who use and maintain this equipment. It relies on basic engineering principles and the accumulated experience of offshore operators, contractors, and manufacturers. The marine drilling riser is best viewed as a system. It is necessary that designers, contractors, and operators realize that the individual components are recommended and selected in a manner suited to the overall performance of that system. For the purposes of ISO 13624-1:2009, a marine drilling riser system includes the tensioner system and all equipment between the top connection of the upper flex/ball joint and the bottom of wellhead conductor outer casing. It specifically excludes the diverter. Also, the applicability of ISO 13624-1:2009 is limited to operations with a subsea BOP stack deployed at the seafloor. ISO 13624-1:2009 is directly applicable to most floating drilling operations, to special situations dealing with deepwater drilling and collapse, to the special considerations required for guidelineless drilling and to operations in cold-weather conditions and H2S considerations. It is important that all riser primary-load-path components addressed in this International Standard be consistent with the load classifications specified in ISO 13625.

ISO 13625:2002 specifies requirements and gives recommendations for the design, rating, manufacturing and testing of marine drilling riser couplings. Coupling capacity ratings are established to enable the grouping of coupling models according to their maximum stresses developed under specific levels of loading, regardless of manufacturer or method of make-up.

This International Standard specifies requirements for performance, design, materials, testing and inspection, welding, marking, handling, storing and shipping of drill-through equipment used for drilling for oil and gas. It also defines service conditions in terms of pressure, temperature and wellbore fluids for which the equipment will be designed. This International Standard is applicable to and establishes requirements for the following specific equipment: a) ram blowout preventers; b) ram blocks, packers and top seals; c) annular blowout preventers; d) annular packing units; e) hydraulic connectors; f) drilling spools; g) adapters; h) loose connections; i) clamps. Dimensional interchangeability is limited to end and outlet connections. This International Standard does not apply to field use or field testing of drill-through equipment.
