Electronic System - Key FeaturesElectronic System - Key Features Modular component design
Dual power supplies for each assembly
Control circuits are in a dual redundant distributed system design
Control circuit communications are based on the RS-485 industry standard using the Motorola 68360 chip set.
Each control CPU and MMI CPU is isolated from each other, using 10 Base T for communications.
Embedded data acquisition system which records each event and alarm.
Data logger which includes permanent storage of data acquisition information and maintenance data base.

Subsea Pod Hydraulic UnitSubsea Pod Hydraulic Unit
All Subsea POD components are manufactured from 316L SS, Nitronics 50/60, or 17-4/7PH.
Hydril Wedge Block Dynamic Seals (1/2”, 1”, & 1 1/2”)
No Hosing, all hydraulic connections are hard piped or made through the Hydril Stab Block.
Spent BOP fluid is captured to bath all components in the spent fluid instead of sea water.
LMRP Disconnect has a positive read back through a mechanical pin actuated Pilot Valve/Pressure Transducer.
Optional 4 pin wet make/break electrical connector in stab to provide power and signal to stack mounted electronics.
