ESD / HIPPS
Emergency Shutdown & High Integrity Pressure Protection System
Reliable Protection for Critical Offshore and Marine Operations
MOWE provides integrated Emergency Shutdown (ESD) and High Integrity Pressure Protection System (HIPPS) solutions for offshore, FPSO, FSO and marine applications.
Our systems are designed to provide reliable and rapid isolation of critical process and fluid systems during abnormal operating conditions. By integrating hydraulic actuators, shutdown valves, control systems and certified instrumentation, MOWE delivers complete valve automation and protection solutions for critical offshore operations.
Emergency Shut Down Valve System (ESDV)
MOWE Emergency Shut Down Valve System (ESDV)
MOWE Emergency Shut Down Valve System (ESDV) is a highly reliable control system specially designed for industries like Oil & Gas, Marine, Power Plant or other Industrial Environments with explosion risks (Ex.) that requires quick response valves.
ESDV control process involves opening or closing of control valves, usually done automatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuator based on electric or pneumatic signals.
These control signals traditionally use 3–15 psi (0.2–1.0 bar). More commonly, industrial applications use 4–20 mA signals, while HVAC systems use 0–10 V. Smart systems also utilise HART, Fieldbus Foundation and Profibus protocols.
ESDV Valve Types
Control valves available for ESD applications include various valve body and trim configurations depending on the process and operating requirements.

Emergency Shutdown (ESD) System
An ESD system provides rapid isolation of critical process and fluid systems during abnormal operating conditions.
Shutdown Valve
Provides rapid isolation of critical process and fluid systems.
Actuation
Electrical, hydraulic or pneumatic actuators can be used depending on system requirements.
Control Signals
Control signals provide automated commands for opening or closing the valve.
Position Feedback
Positioners provide feedback and control of actuator valve opening and closing.
High Integrity Pressure Protection System (HIPPS)
High Integrity Pressure Protection
HIPPS is a high-integrity protection system designed to provide protection against excessive pressure conditions within critical process systems.
The system detects a defined pressure condition and initiates a rapid isolation action through dedicated shutdown valves to protect downstream equipment, piping and associated process systems.
For offshore and marine applications, HIPPS can be integrated with shutdown valves, actuators, pressure instrumentation, control logic and associated safety systems.
HIPPS Protection Components
Pressure Monitoring
Pressure instrumentation monitors critical process conditions.
Safety Logic
Safety logic evaluates the monitored process condition and initiates the required protection action.
Shutdown Command
A shutdown command is transmitted to the dedicated isolation valve system.
Valve Isolation
The ESDV / HIPPS valve rapidly isolates the protected process or fluid system.
