Multiplex Control Pod - Oceaneering

Electro-Hydraulic (E/H) HousingThe E/H Housings consists of multiple solenoidactuators, pilot valves, differential pressuretransducers, and pressure switches for enhancedcommand and monitoring capabilities. Watersensors have also been supplied to provide anadditional layer of diagnostics for sensing water inthe housings. The E/H Housings can accept up toone-hundred, thirty four (134) devices total.Pressure transfer assemblies have been suppliedto provide dielectric volume compensation up to12,500 feet of seawater (fsw). Internal and externalpressure relief valves are also provided to protectagainst housing pressurization during deploymentand retrieval operations.Using “intelligent” device arrangement andadvanced tubing connection techniques allowsfor a quick (15 minute, once accessible) meantimeto repair (MTTR) without disturbing tubing orneighboring instrumentation.Key Features• Contemporary, Corrosion Resistant Alloys• Compensators for Dielectric Volume• Dual-pass Wiring• Intelligent Device Arrangement• Easy Serviceability (15 minute Mean-Time toRepair)• 134 Device CapableSingle wire insulation continuity is achieved andmaintained through the use of “dual-pass” wire andconnector back-shell boot seals.Pressure TransferAssembly60 Pin CableConnector Plug withTest Port and BackshellBoot SealsQuick DisconnectHydraulic PilotConnections2

Lower Valve Unit (LVU)Sub-plate mounted (SPM) valve manifolds areprovided to supply control fluid to individuallymounted, one half (1/2) inch, one (1.0) inch,and one and one half (1-1/2) inch SPM valves.Additionally, SPM valves can be supplied witheither normally “open” or normally “closed” valvepositions.The LVU comes equipped with a fully retractable(into the pod assembly) lower stack interfaceusing telescoping piping. Furthermore, all LVUpiping utilizes “quick-connect” type connectors forenhanced serviceability. Valves and regulatorsare also equipped with “quick-connect” seal-subconnections for hassle-free repairs.In addition, the LVU is supplied with a LMRP podreceiver and lower stack pod receiver to enable a“quick disconnect” of the pod (from the BOP stack)for scheduled maintenance. Pressure assist packerseals have been provided for exceptional hydraulic“receiver” stab seal performance.The LVU comes equipped with a regulator manifoldthat provides pressure to meet specific “stack”circuit requirements. Five (5) independent, remotelycontrolled regulators are provided for the control ofthe Regulator Manifold Pressure, Upper and LowerAnnular Pressures, and the LMRP and WellheadConnection Pressures.Key Features• Contemporary, Corrosion Resistant Alloys• Generous Use of “Quick-Connect” Connections• 12,500 fsw Capable• Dual Reference Pilot Accumulators• Fully Retractable Lower Stack interface• Easy Serviceability (15 minute Mean-Time to Repair)• Pressure Assist Packer Seals• Highly Configurable Function CountTypical SPM Valve PopulationEexample Only)• Lower Marine Riser Package• (18) - Straight through, pilot functions (from SEM)• (10) - One inch (1”) SPM valves• (44) - One half inch (1/2”) SPM valves• (6) - One and one half (1-1/2”) SPM valves• Lower Stack• (6) - Straight through, pilot functions (from SEM)• (22) - One inch (1”) SPM valves• (36) - One half inch (1/2”) SPM valves• (4) - One and one half (1-1/2”) SPM valves4
