BACKGROUND In late January 2004, a Subsea Control System User Group was formed. The Subsea Control Systems User Group identified a number of issues on which the operators may like to see progress in terms of standardization of interfaces. This may facilitate greater reliability for subsea field developments and reduce risks to functionality and schedule. The scope of the SIIS initiative is distinct from IWIS (standardization for downhole instrumentation) and it is limited to subsea production system instruments interfacing directly to the Subsea Control Module.


1 INTRODUCTION

This specification includes the link segment specifications, acceptance criteria, test parameters and test methods for SIIS level III testing from top-side to sea bed pressure and temperatures as specified in API 17F.

2 PURPOSE AND SCOPE

For purposes of system conformance, the SIIS link segment is standardized at the test points described in Figure 1. The test points enable link segment and component testing and provide the basis for link segment and component acceptance criteria for qualification and FAT. Note that all test points may not be accessible in an implemented system. The SIIS twisted-pair link segment (TP1 to TP6) shall meet or exceed the 100BASE-T twisted-pair link segment specifications. By meeting this specification the need for additional BER testing is eliminated and provides a better understanding of operational margins. The SIIS link segment twisted-pair cables shall meet or exceed the component specifications in TIA/EIA- category 5. The SIIS link segment wet mate connectors should meet or exceed the component specifications in TIA/EIA- category 5. The SIIS link segment assembly transmission and coupling parameters are specified from TP2 to TP5. The subsea control module transmission and coupling parameters are specified from TP1 to TP3. The sensor module transmission and coupling parameters are specified from TP4 to TP6. The wet mate connector transmission and coupling parameters are specified from TP2 to TP3 and TP4 to TP5.
