Subsea electronic modules
View Patent ↗A module for use as a subsea electronic module of a subsea well, comprises an input ( 7 ) for receiving signals from a sensor arrangement which senses at least one parameter of a well, the module including a plurality of separate, different electronic circuits ( 9 ), each of which is selectable to be in communication with said input and each of which is adapted to co-operate with a respective, different form of such a sensor arrangement.
1. A subsea electronic module (SEM) for a subsea well, the subsea electronic module comprising:
an input for receiving signals from a sensor arrangement which senses at least one parameter of a well,
a plurality of separate, different electronic circuits, each of which circuits is selectable to be in communication with said input,
wherein each of said plurality of separate, different electronic circuits is separately configured to co-operate with a different one of a corresponding plurality of different sensor arrangements each of which senses the same at least one parameter of a well,
wherein each separate one of said electronic circuits is further configured to receive signals from the respective different cooperating sensor arrangement via the input when the respective cooperating sensor arrangement is operationally employed and in communication with said input.
2. A subsea electronic module according to claim 1 , wherein said circuits are carried by a circuit card of the subsea electronic module.
3. A subsea electronic module according to claim 2 , wherein said circuits are or conform to the circuitries of respective ones of different sensor arrangement manufacturers, incorporated as IWIS interface cards on to said circuit card.
4. A subsea electronic module (SEM) to provide control functionality for a subsea well, the subsea electronic module comprising:
an input for receiving signals from either of any one of a plurality of different sensor arrangements, each sensor arrangement having a different manufacture configuration, each sensor arrangement functionally configured to sense a same parameter of a well; and
a plurality of separate, different electronic circuits configured to cooperate with a corresponding different one of the plurality of sensor arrangements, each of the plurality of separate, different electronic circuits carried on a same circuit card and individually selectable to communicate with the respective cooperating different one of the plurality of sensor arrangements through said input when the respective cooperating sensor arrangement is employed and in communication with said input.
5. A subsea electronic module according to claim 4 , wherein each of the plurality of different sensor arrangements is characterized by being configured by a different manufacturer, and wherein each of the plurality of separate, different electronic circuits is configured to conform to the circuitries of the respective cooperating different one of the plurality of sensor arrangements.
6. A subsea electronic module according to claim 5 , wherein each of the plurality of separate, different electronic circuits are configured as intelligent well interface standardization (IWIS) interface cards.
