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 or exceed high quality
ISO 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
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.

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.
Lift Mechanism
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 or exceed ISO industry standards.

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.
Subsea Electronics Module
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.

Dril-quip’s IWOC System is used to install
the tree while maintaining necessary control
of the Emergency Disconnect Package (EDP)
and Lower Riser Package (LRP) when applicable. It is also used to install the tree cap.
The IWOC System utilizes the same control
panel and hydraulic power supply as is used
to install the tubing hanger. A larger hose
umbilical and reel may be required to accommodate the additional functions associated
with the tree, EDP and LRP. If so, corresponding sheaves to accommodate the larger
hose bundle will also be supplied.
