1 Setting a Global Standard Production Control Systems

2 Multiplex Control System Dril-quip s Multiplex Production Control System is a key component of the subsea completion system. The system is designed to meet ISO /API 17F standards and is tested to confirm reliability predictions. With Dril-quip s system, users have real-time access to tree functions, tree equipment status and sensors monitoring reservoir performance. The system s open architecture allows for control and monitoring of over fifty wells and the collection of all data within five seconds. MODBUS protocol allows users to easily link to the platform control system. 1

3 A single control module can operate 30 functions and monitor 32 sensors. Modules are constructed from field-proven components and the system is designed for 20 years operating life. A flexible design allows Dril-quip engineers to create a system for your application employing standard equipment modules. Dril-quip can package this system for shallow or deepwater applications up to 10,000 feet in depth. Innovative Communication Dril-quip s innovative fiber-optic-based communications system takes advantage of over 10 years of experience using fiber optics in subsea applications. It is the only system on the market that provides four independent channels. Reliable noise-free communication allows each channel to operate at 115K baud for a total of 460K baud. This provides faster data throughput for measurement of well and equipment performance. Dril-quip s Multiplex Control System uses single-mode fiber-optic technology that provides reliable communications over 100-plus miles of fiber-optic cable. 2

4 Surface Control System Equipment Master Control Station Master Control Station Dril-quip s Master Control Station (MCS) allows the operator to control and monitor the subsea completion and surface equipment in the production control system. The station also provides conditioned and protected power for the control system. The unit is configured to monitor input and output supplies. The station s open architecture is compatible with the latest industry technology, using high bandwidth Ethernet communications to achieve optimal throughput of data. Dril-quip s design offers the customer a highly reliable, flexible and high-speed field-proven solution. Hydraulic Power Unit Dril-quip s Hydraulic Power Unit (HPU) is designed using computerized hydraulic analysis to meet your project specification. Standard designs for differing environmental requirements are available employing Delta V Controllers. Third Party Unit Dril-quip s Third Party Unit (TPU) can be customconfigured with computers to monitor a variety of third party sensors. The Third Party Unit can also be configured to include a data historian with remote access capabilities. Hydraulic Power Unit Topside Umbilical Termination Unit Dril-quip s termination unit provides an electrical, hydraulic and optical interface to the umbilical. Each unit is configured to meet customer specifications and industry standards as well as zone and environmental requirements. Umbilical Termination Unit 3

6 Subsea Control System Equipment Shallow and Deepwater Subsea Control Modules Dril-quip s Shallow and Deepwater Subsea Control Modules offer operators advanced multiplex electrohydraulic systems designed to control and monitor a subsea completion system. Each module includes a Subsea Electronics Module (single configuration), up to 12 hydraulically latched pilot control valves with pressure transducers, metalsealing hydraulic couplers, electrical/optic connectors, hydraulic fluid filters and accumulators. The Shallow Water Control Module is attached to the tree with a simple diver-assisted latch mechanism. It is designed for subsea operations in water depths up to 1,000 feet. The module provides control and monitoring of 12 hydraulic functions. It also monitors up to 16 electrical sensors. The Deepwater Control Module installs into a mounting base that provides guidance, soft landing, coupler make-up and module lock. Dril-quip s base and funnel are designed to easily mount to subsea trees, manifolds and distribution units. The deepwater module is designed for subsea operations of up to 10,000 feet, and provides control and monitoring of 30 hydraulic functions (also expandable). Monitoring of 32 or more electrical sensors is provided. Both control modules communicate via high-speed (115K baud) Fiber-Optic or Signal-On Power (9.6K baud). The modules employ dual modems and power supplies in the Subsea Electronics Module. Each module has a design life of 20 years and is designed to meet ISO /API 17F standards.

7 Deepwater Subsea Control Module Optic/Electric Connector Compensation High-Pressure Accumulator Subsea Electronics Module Low-Pressure Accumulator Subsea Hydraulic Filter Base Plate Receiver Plate Valve Assembly Manifold Hydraulic Couplers Guide Pin Subsea Electronics module Dril-quip s Subsea Electronics Module (SEM) is the intelligence hub of the subsea control module. It acquires data from subsea sensors and provides control of the completion system through valve actuation. The module is microprocessor-based (16 bit) for an optimal combination of capability, reliability and simplicity. Dril-quip s design incorporates downloadable software allowing for reprogramming, changing operation, configuration management or diagnosis without requiring retrieval of the module. One communications channel is dedicated to module operation and the remaining channels are available for digital sensors with RS-485 interfaces, such as downhole pressure temperature sensors, intelligent-well sensors and flow sensors. The module is designed for low power consumption, minimizing the size, weight and cost of the umbilical. The SEM is capable of operating with either single or three-phase power. Dril-quip s SEM can communicate using a number of technologies: fiber-optic wide bandwidth, ethernet or Frequency Shift Keying (FSK), at baud rates of 1,200, 2,400, 4,800 and 9,600 Baud. FSK can be separate from the power line or impressed over the power cores for signal-on-power communications. Subsea Electronics Module 6

8 Installation and Workover Control System For tubing hanger installation Electric Power Hydraulic Power Emergency Shutdown Sheave Dril-quip s Installation and Workover Control (IWOC) System provides direct control to the tools used to install the tubing hanger, tree and tree cap. Hose Bundle Dril-quip s IWOC System incorporates all of the necessary controls required to deliver hydraulic power to each of the functions required. It can accommodate electric pass-through to all of the electric downhole functions that may be required.
