“…This enclosure is integrated in a subsea modular unit for installation, intervention, and retrieval [17]. The main drawbacks of this solution are firstly the size of CPDUs as well as the complexity in engineering, testing, subsea hook-up connection, and downtime during maintenance [16] [17]. The mass and weight of the subsea enclosure increases with the sea depth and operation phase.…”

“…This topology would make each module a complete standalone module all connected in series where signals and power are passed from one module to the next. An electrical fault in one of the modules could paralyze the complete system [16] so the solution runs two Daisy-chains from the umbilical termination to maintain the redundancy of having 2 CPDUs. The solution would be able to identifying a faulty module without disconnection [16] and replace a power hub or control hub without stopping production.…”

“…Subsea gas compression is a new technology that is responding to the market need for extending the lifetime of existing subsea gas fields [16] [20]. This type of subsea process station consists of process modules that are retrievable units with functions such as gas compressing, separation or cooling that together make the compression station.…”

This paper reports on a trade study of feasible concept alternatives for control and low voltage power distribution architecture for subsea process stations. Subsea gas compression is a new process station technology that is responding to the market need for extending the lifetime of existing subsea gas fields. These subsea process stations are deployed in deeper water, farther offshore and in harsher environments. The demand for a more efficient, less complex, and cheaper solution is pushing the technology development and screening for alternative concepts. The SPADE methodology has guided a trade study of concept opportunity exploration for alternative distribution architectures. The Pugh matrix demonstrated its ability to provide a simple overview of the multiple factors in a decisionmaking situation, with extensions for risk and opportunity assessment.
