Intelligent Well Interface Specification To assist the integration of downhole power & communication architectures, subsea control systems and topsides by providing recommended specifications (and standards where appropriate) for power & communication architectures, and associated hardware requirements. Such integrated systems should allow the operator to implement more downhole 'smart' equipment in a timely and cost-effective manner. Improving compatibility should also eventually benefit reliability, and transparency (for diagnostics) when tackled as an industry group.

Intelligent Well Interface Standardisation • In 1996, the IWIS JIP was kicked off by BP, AGIP, ELF, STATOIL, SAGA, Norsk Hydro and Shell. • IWIS define interfaces between downhole vendor card and subsea control system with respect to: • Communication • Power • Hardware • Implementation JIP /plugfest performed • The IWIS Recommended Practice was finalised at the September 2007 workshop. • This is now available to industry in support of ISO 13628 - 6.

IWIS • Subsea: − RS-422, allways support 9600bit/s, alternative speeds allowed − TCP/IP PPP − Power 24W / 96W − Voltage 24V • Topside
− Ethernet − TCP/IP PPP − Subsea vendor proprietary interface is also an option

Subsea Instrumentation Interface Standardisation • Kicked off in 2004 • SIIS define interface between subsea production system instruments and the Subsea Control Module.
• Plugfest performed in 2009 • Specification submitted to ISO13628-6 committee • Further detailed work ongoing including: • Recommended practice • Cable test specification

Choice of communication protocols and interfaces? • TCP/IP for communication between SPCU and SEMs • Ethernet according to SIIS level 3 and CanBus according to SIIS level 2 for all external connections to SCM.
• IWIS for downhole communication • SIIS RP and IWIS RP should be followed • SIIS level 2 should be the default interface for subsea instruements • SIIS level 3 should be used when need for transparent channel and/or high datarate. These needs may come from e.g. transfer of raw data or extended access requirements, in some cases due to low degree of maturity of instrument.

MCS-DCS Interface Standardization
21
MDIS history • MDIS history • Following the success of the SIIS JIP in developing a standard interface between the subsea control module (SCM) and subsea sensors, the concept of an MCS-DCS network originated, aimed at streamlining the Master Control System and Distributed Control System communications on topside systems through a collective effort between subsea controls vendors, topsides specialists and oil companies. • The MDIS network was officially launched in February 2010 and aims to meet 4 times a year, alternating between the US and Europe. Meetings are held during the same week as SEAFOM and SIIS. • MDIS vision • ''To optimize the MCS and DCS communications of topside systems (ref. ISO 13628-6), by developing a standard interface, in order to simplify implementation of data communication links, whilst increasing the data quality''
22
MCS-DCS Interface Standardization
23
MDIS aim to provide • Simplified implementation and testing of the interface • Reduction in the risk of interface failures resulting in system faults and the cost of implementation due to delays and rework
• Ensure clear logic and control and status interface boundaries (aids future MCS/DCS logic development/implementation) • Repetition of data use within objects is avoided • Operator perspective i.e. to enable safe control and monitoring via the DCS • To ensure flexibility for future vendor specific development and maintenance of subsea products

Obsolescence management • IEC 62402 have two complimentary definitons of obsolescence: − Transition from availability from the original manufacturer to unavailability − Permanent transition from operability to non-functionality due to external reasons • Obsolescence management is defined by IEC 62402 as: − Co-ordinated activities to direct and control an organization with respect to obsolescence

Joint Operator Obsolescence Management Specification • Work started early 2011, based on Total GS-EP-SPS-028, issued Oct-2009 • Joint effort between BP, Chevron, Shell, Statoil and Total • The specification is a supplement to IEC 62402: Obsolescence management - Application guide. • First revision of the specification was issued Oct-2011 and is intended to cover the complete subsea production control system on new deliveries. • The next revision of the specification shall extend to equipment which has already been delivered and is planned issued Oct-2012. • Further revisions will extend to subsea production equipment in general.
29
Joint Operator Obsolescence Management Specification • The purpose of this document is to define the pro-active Obsolescence Management Process as it applies to subsea production control systems and detail minimum subsea equipment vendor requirements to manage the risks of obsolescence through activities associated with: − Preventing − Predicting − Resolving
