5.5 Well Controls and Shutdown Requirements

5.5.1 General

• HIPPS valve shall be closed first and opened first

• WV & CV shall be closed / opened simultaneously

• HIPPS panel shall be hydraulically interlocked with local CV panel to

close CV after HIPPS trip or manual close

• HIPPS panel shall be hydraulically interlocked with WHCP panel to

initiate WHCP CPSD after HIPPS trip or manual close

There are two types of production facility shutdowns activating wellhead valves / surface valves. Logic for this is performed in the WHCP:

• Emergency Shut Down (ESD)

1. Manual ESD

2. Fire detection by Fusible plugs



An ESD is initiated by an emergency pushbutton on the WHCP or in response to fire detection (by Fusible plugs). This requires the closure of all the actuated valves CV & WV, SSV and SC-SSSV.

• Remote Process Shut Down (PSD)

This will initiate closure of CV, WV and SSV by remote shut down signal.

5.5.2 ESD Section

5.5.2.1 Manual ESD

An ESD is initiated by manual operation of local ESD push button (push for ESD & pull to reset) at the WHCP. This push button on pushing (ESD) shall de-energize solenoid valve fitted on the hydraulic circuit to close CV,WV and SSV in the following sequence. This push button on pulling (reset) shall energize the solenoid valve and reset hydraulic interface valves to open the SSV, WV and CV in the following sequence. Activation of this local ESD reset switch shall not affect other circuit hydraulic pressure.

An ESD shall cause the wellhead and surface valves to close as per sequence indicated below:-

Normal Closing Sequence

CV and WV (simultaneous) First

SSV (with 2 sec. delay) Second

SC-SSV (with 9 sec. delay) Third

An ESD re-set shall cause the wellhead and surface valves to open as per sequence indicated below:-

Normal Opening Sequence

SC-SSV First

SSV Second

WV and CV (simultaneous) Third

The panel shall operate with delayed opening and closing of Wing Valve, SSV in order to protect the SC-SSV. The vendor shall provide adjustable hydraulic delay mechanism within the SC-SSV circuit.



5.5.2.2 Fire detected ESD

Fire at wellhead shall be detected by 4 nos. Fusible plugs. A fire at the wellhead causes the eutectic material in the fusible plugs to melt and vent the supply line pressure and initiates a well head shutdown. These fusible plugs shall activate to de-energize solenoid valve fitted on the hydraulic circuits to close CV & WV, SSV and SC-SSSV. Fire detection shall cause the wellhead and surface valves to close as per the sequence indicated below.

Normal Closing Sequence

CV and WV (simultaneous) First

SSV (with 2 sec. delay) Second

SC-SSV (with 9 sec. delay) Third

An ESD re-set shall cause the wellhead and surface valves to open as per sequence indicated below:-

Normal Opening Sequence

SC-SSV First

SSV Second

WV and CV (simultaneous) Third

The panel shall operate with delayed opening and closing of Wing Valve, SSV in order to protect the SC-SSV. The vendor shall provide adjustable hydraulic delay mechanism within the SC-SSV circuit.

As the local ESD push button will close in the event of a Fusible Loop shutdown, the. Fusible Plug Loop re-charged after fitting of replacement plugs and well head control system shall be reset locally. Vendor shall develop a logic that in case of Fusible Plug Shutdown the loop will remain isolated without dispersing oil of the circuit outside.

A common logic shall be made in such a way that after local ESD or Fire ESD activation, SC-SSSV, SSV & WV shall open only after the local reset pushbutton is activated.

The above ESD Shutdown header and the logic supply header shall be provided with a pressure gauge and a pressure switch.



5.5.3 Closure of actuated valves

5.5.3.1 HIPPS valve closure

1. Flow line High High pressure 2. Manual push button on WHCP

5.5.3.2 WV & CV (simultaneous) closure

1. Flow line High High pressure 2. Fire detection by fusible plugs 3. Manual ESD push button on WHCP 4. WHCP mounted push button for WV & CV close 5. Remote PSD 6. Remote close WV / CV 7. Local Close/Open HIPPS 8. Local Close/Open SSV 9. Local Close/Open SC-SSV 10. Remote Close Wellhead

5.5.3.3 SSV closure

1. Flow line High High pressure 2. Fire detection by fusible plugs 3. Manual ESD push button on WHCP 4. Remote PSD 5. Remote Close Wellhead 6. Local Close/Open SSV 7. Local Close/Open SC-SSV

5.5.3.4 SC-SSV closure

1. Fire detection by fusible plugs 2. Manual ESD push button on WHCP 3. Local Close/Open SC-SSV.



5.5.4 Hydraulic Logic Control Circuit

5.5.4.1 SC-SSSV

The SC-SSSV is controlled with pushbuttons for open / close control. The logic for the SC-SSSV is derived from the ESD logic and so the SC-SSSV will be closed manually or by an ESD detected by the Fusible plugs. A flow control valve would be provided in the logic to enable the required closing sequence after an ESD. The actuator hydraulic supply pressure is indicated by a local pressure gauge. As solenoid valve fitted on the hydraulic circuit, de-energizes on ESD, this will require resetting after an ESD.

The SC-SSSV is flapper type which will require manual pressure equalization across the SC-SSSV prior to being opened. (i.e. not self-equalizing). The Vendor shall provide a system to open the SC-SSSV from the panel.

The SC-SSV shall close on the conditions indicated in 5.5.3.4

5.5.4.2 SSV

The SSV are controlled with pushbuttons for open / close. The SSV & WV shall be interlocked so that it can only be opened if the SC-SSSV is open. The actuator hydraulic supply pressure is indicated by a local pressure gauge.

The SSV shall close on the conditions indicated in 5.5.3

The logic for the SSV is derived from the ESD logic and as solenoid valve fitted on the hydraulic circuit de-energies on any of the above conditions, this will require resetting after an ESD.

The logic shall also include remote open / close operation of these SSV.

Upon closing of SC-SSV, SSV & WV on Fire / ESD, an automatic opening or remote opening shall not be possible.

The SSV shall be interlocked so that it can only be opened if the SC-SSV is open.

The actuator hydraulic supply pressure is indicated by a local pressure gauge. The logic for the SSV is derived from the ESD logic header and, as the manual latching valve resets on loss of pressure, this will require resetting after an ESD.
