• Standard protocols integrated (and segregated) into the same physical communication lines

• SEMs integrate all necessary functions and hardware

• Simpler umbilical, simpler hardware and less connections

• No need of full SIL certified control chain (standard communication network)

LV Power and Control System as part of subsea processing

Main Saipem requirements

for Subsea Processing Plants

• Necessity to run logics such as sequences and closed control loops.

• Fast closed control loops.

• Continuous control valves vs. stepping control.

• Simultaneous valve actuations and System promptness (faster actuation of valves): hence higher power consumption.

• Higher frequency of valves actuation.

Siemens Subsea Control System features

• Possibility to run logics such as sequences and closed control loops, even subsea.

• Real time protocol (Profinet IO), also between topside and subsea.

• Subsea CPU with real time OS (QNX).

• All electric control system.

• Subsea Power Manager (SPM).

• Advanced Condition Monitoring System integrated with PCS and with Safety system: everything in the same control pod.

Main requirements for Subsea Processing

• Condition Monitoring.

• Safety functions (even SIL certified).


13

Status per April 2018

• Siemens Subsea Power Grid o Factory floor SIT concluded. Shallow water SIT and TRL 4 in 2018.

• Joint Development Agreement o Detailed design completed

o Testing and API17F-Q1 qualification of internals finished

o Started assembly of main units for prototypes

o Testing of main units 2018/2019

o Integration test all units together, extended test with third party vendors

o TRL 4 by Q1 2019


14

Benefits for the Subsea Industry

• New approach to subsea low voltage power & control infrastructure based on proven onshore architecture and philosophies

• Use of open standards is supported by large service providers and gaining momentum with operators

• Control infrastructure with determenistic behaviour

• Supports safety certified functions (SIL 3)

• Supports electrical power budget > 40kW

• Subsea system could become integrated part of topside/onshore plant control

• Fit for Long Subsea Tie-back
