3.1.2 direct hydraulic control system System using hoses to transmit hydraulic pressure directly to assigned functions. 3.1.3 discrete hydraulic control system System using pilot hoses to transmit hydraulic pressure signals to activate pilot-operated valves assigned to functions. 3.1.4 electro-hydraulic control system System using electrical cables in a subsea umbilical to transmit command signals to solenoid-operated valves, which in turn activate pilot-operated control valves assigned to functions. 3.1.5 hydraulic power unit HPU Unit that provides a stable and filtered supply of hydraulic fluid to the control system. 3.1.6 master control station MCS Unit that controls and monitors the control system. It can range in complexity from a manual hydraulic panel to an automated system. 3.1.7 multiplex control system System using electrical cables or fiber optics in a subsea umbilical such that, on each element, multiple distinct functions are independently operated by dedicated serialized coded commands. NOTE Solenoid-operated valves in turn activate pilot-operated valves assigned to functions. 3.1.8 normal class control function Individual control system function that operates a “normal class device”; see API 17G for normal class definition. 3.1.9 open-water intervention riser system OWIRS See API 17G. 3.1.10 remote control panel Enclosure displaying an array of switches, push buttons, lights, and/or valves and various pressure gauges or meters to control or monitor functions. NOTE Installation locations typically include the on deck, drill floor, and driller’s cabin. 3.1.11 riser control module RCM Modules typically deployed as part of a TBIRS inside of a marine drilling riser and BOP stack to monitor, control, and operate the tubing hanger, SSTTA, and downhole functions.
3.1.12 safety class control function Individual control system function that operates a “safety class device”; see API 17G for safety class definition. 3.1.13 safety function See API 17G. 3.1.14 stab plates Mechanism comprised of two mating sub-assemblies, one of which is made of a number of hydraulic and/or electric and/or optical coupler halves, each carrying a separate service, that mate simultaneously with corresponding coupler halves on the other sub-assembly when the two sub-assemblies are brought together. 3.1.15 thru-BOP intervention riser system TBIRS See API 17G. 3.1.16 umbilical Group of functional components, such as electric cables, optical fiber cables, hoses, and tubes, laid up or bundled together in combination with each other that provides hydraulics, fluid injection, power, and/or communication services. NOTE Other elements or armoring may be included for strength, protection, or weight considerations. 3.1.17 umbilical clamps Secure umbilical to another piece of equipment (e.g. marine riser, choke or kill line, cable, wire). 3.1.18 umbilical reel Facilitates controlled deployment and retrieval of the umbilical to the desired working depth while also acting as a storage and transport device for the umbilical. 3.1.19 umbilical sheave Route and support the umbilical during installation, retrieval, and operation. 3.1.20 uninterruptible power supply UPS Supplies power to topside control equipment in the event of loss of rig power. 3.1.21 workover control module WCM Electro- and/or hydraulic system used in an OWIRS to control and operate workover and intervention functions via the master control station (MCS) and to monitor, control, and operate the emergency disconnect package (EDP) and well control package (WCP).
4 Equipment Requirements 4.1 General 4.1.1 General Requirements Requirements in this section shall apply to all surface and subsea equipment covered by this document. Some equipment contains functionality to support operation of safety class control functions. For these pieces of equipment, the following requirements are specific to the safety class control functions: ― risk of unintended operation of safety class control functions shall be mitigated; ― safety class control functions shall be protected by interlocks, protective covers, or isolation of dedicated control lines; ― visible and/or audible indication of execution of safety class control functions shall be provided. Manufacturer shall define a service condition for all IWOCS equipment for storage, shipping, and operation. Service conditions should be in accordance with API 17F. NOTE IWOCS for TBIRS operations may require higher temperature ratings than given in API 17F. Design of equipment shall comply with hazardous area requirements necessary for safe operation in the planned installation location.
