INTRODUCTION
This document is part of the Operating Manual, which covers the Subsea Systems Flowlines & Risers . The Subsea System operations manual together with other manuals and related documents comprise the Facility Management System or FMS. The Subsea System is a controlled document maintained by MODEC INTERNATIONAL LLC, the Contract Operator of the Baobab Field. Any question concerning this document or its contents should be addressed to the Contract Operator.
This document gives a general description of and the task lists for the operation of the Subsea system. Its purpose is to educate those who are unfamiliar with the system in how it works and the way in which the system is to be started, stopped and operated safely. This document can be used as a reference document in formulating maintenance isolation procedures.
Information contained in this document applies only to the Subsea System on the Baobab Field Development project. The information contained gives general design information, alarm settings and trip points for the various components as well as the start up, shut down and normal operating procedures for the Subsea System.
Refer P&IDs 6220-PD-20-01-00001,6202-PD-02-05-00173,6219-PD-19-01-00001,1072-MI20-9020-0118,1072-MI20-9020-0146,6202-PD-02-01-00169,6202-PD-02-03-00171,6202-PD-02-02-00170,BAO-CNR-SU-PID-00187-04,BAO-CNR-SU-PID-00187-06,BA0-CNR-SU-PID-00187-01,BAO-CNR-SU-PID-00187-02,BAO-CNR-SU-PID-00186-02,BAO-CNR-SU-PID-00186-01 AND Alarm List (PT REF : 1072-CNR20-0002-0002)
See the Definitions Document of the FMS.
Every plant system covered by the Subsea System has been assigned to a single position title in the permanent offshore crew. The person filling the named position is jointly responsible with his off-duty relief for the integrity and the safe operation of the assigned system. In like manner it is that person's responsibility to verify the accuracy of the information contained in this document. Any confirmed inaccuracy shall be tracked by the Offshore Installation Manager (OIM) until formally corrected.
The job title of the position responsible for this system can be found in the System Responsibility Matrix in the Safety Management System (SMS) Manual (Doc No. 1072-MI20-15ST-0170).
In the execution of the subsequent procedures all permit to work, PPE and isolation procedures required by the Baobab SMS (Doc No. 1072-MI20-15ST-0170) shall be followed. If any doubt exists as to the correctness of valve positions or sequence of operations then they should be discussed with the supervisor and approval sought from the Facility Manager to change the procedure. These changes shall then be captured on a permanent basis by submitting them through the required document control procedures. Specific requirements for HSE are given in each section of the procedures.
Shut down overrides for this system can be invoked only when the system is continuously monitored. Proper procedures and systems should be followed while testing the trips. Where overrides are put in place for testing, these shall be removed at the end of testing so as not to inhibit shutdown functions.
The main Flowlines within the Subsea facilities are as follows:
Three Production Risers (Riser No. 1,3 & 5)
One Gas Import/Export Riser
One Water Injectio 24524m125y n Riser
One Gas Lift Riser
One Umbilical
Provision for additional five future risers
Initially seven Risers (three production, one gas import/export, one water injection, one gas lift and one Umbilical) are installed / connected at the external turret on the FPSO. In addition ,provision has been made for a total of five future risers (two production, one gas lift, one water injection and one umbilical). Flexible risers are used to link production and service functions in the subsea manifolds with processing facilities and controls on the FPSO. The turret is the mooring point for the FPSO as well as the interface between the subsea system and the topside modules. It serves as a connection point between the FPSO and the subsea system and is the pathway for getting oil from the reservoir into the vessel through subsea risers. The swivel stack is mounted on top of the turret, which itself is capable of rotating by means of upper and lower bearing allowing the vessel to weather vane around the turret. Flexible hose carry the well fluids from well manifolds, DCN and DCS, transporting it through the turret to the swivel stack. The swivel stack has a collection of the couplings for well fluids ,water injection, gas export, gas lift, hydraulic & electrical control signals. Production fluids shall be transported to the FPSO moored some 4-5 km from the drill center north (six well heads no. 11,12,13,14,15 and 16) and from drill center south (Six well heads No. 21,22,23,24,25 and 26) via production manifolds through three production risers. Provision has been made at DCN for additional wells to be tied in using the daisy-chain approach. The production wells have been drilled from two subsea manifolds on the western shoulder of the sub-sea canyon while the water injection wells have been drilled from two sub-sea manifold system tied back to the FPSO. The control system for subsea manifold is electro-hydraulic. Control is carried out by a multiplexed hydraulic control system ,where connections between the surface and subsea are via an umbilical. The main umbilical is provided with power/communication signal quads, HP &LP hydraulic control lines and chemicals. Physical separation between the umbilical and production pipeline shall be maintained at a nominal 15 m, where possible, to avoid excessive thermal effects on the umbilical.
Figure Process Flow Diagram of the Subsea System.
The main function of the subsea system is to connect the FPSO (top side processing unit) with the well heads to receive well fluids from well heads to the FPSO. The system also provides water injection for pressurization of the field, gas lift facility, chemical injection (Methanol, Scale Inhibitor, De-emulsifier, Wax Inhibitor & Corrosion Inhibitor) and hydraulic control of subsea valves and subsea instrument signal transmission to SCU (Subsea Control Unit) and DCS for monitoring and control the subsea process variables. Operator control and monitoring of the subsea system is via the FPSO DCS. DCS connected with Subsea Control Unit (SCU). SCU and SPCU (Subsea Control & Communication Unit) are the main control unit for subsea system connected with UPS (Uninterruptible Power Supply),HPU (Hydraulic Power Unit),DCS and topside ESD. The SCU is comprises of a number of modular units containing signal board computers. Operation and monitoring of subsea equipment is carryied out via Subsea Control Modules (SCM) which are connected to SCU. Electrical power and communications are provided between the surface and subsea on a combined communication and power system. I,e the same electrical conductors are used to provide both power and communications signals. Each SCM has two Subsea Electronic Modules (SEMs) to maintain the redundancy into the SCM. The SCM contains a set of solenoid operated directional control valves (DCVs) . These are used to switch hydraulic pressure to the particular function (e.g. tree or manifold valve). The solenoid operated DCVs have two dual wound solenoids, such that a valve open signal is directed to the open solenoid and a valve close signal is directed to the close solenoid. The solenoids are dual wound to allow the signal to be presented by either SEM. Design is such that the solenoid operated DCV is fail stay put on loss of electrical/ power/communications and fail closed on loss of hydraulic power.
There are twelve well heads, six from drill center north (DCN) and six from drill center south (DCN) connected through flexible hose to three production risers (riser no. 1,3 & 5). The well heads from DCN are connected with production riser no.1 & 3 and the well heads from DCS are connected with production risers no.3 & 5. Each production line from the well head has a subsurface safety valve (SSSV), one Production Master Valve (PMV), one Production Wing Valve (PWV), one production Choke Valve (PCV) two Manifold Production Valves (MPV) on the lines connecting the two production risers and a Manifold Test Valve (MTV) connected to the line with multi-phase flow-meters (2 off). Each production line from the wellhead has a gas lift line with associated valves and instruments connected with the annulus of the respective production well. In the annulus line of each production well head there are Annulus Access Valve (AAV), Annulus Insert Valve (AIV), Annulus Master Valve (AMV) and gas lift line with associated valves and instruments is connected with the annulus line. Each well head provided with demulsifier, methanol and scale inhibitor injection line. Each wellhead is production riser provided with methanol, scale, wax and corrosion inhibitor injection line and at the inlet of multi-phase flowmeters, demulsifier injection line also provided.
There are three off 11" ID production risers coming from the DCN and DCS manifolds ,connected to swivel manifold and finally, after passing through the turret, connect to the topside production manifold.

From the third stage booster gas compressor discharge, one, six-inch gas lift riser is connected to the gas lift swivel (TU-FAS-0816) in the turret area. The gas lift riser No. 4 (TU-FAS-0230) from the gas lift swivels goes to the production well manifolds North & South. The gas lift riser (Riser No. 4) connected by flexible hose to the drill center North and South. In both the production manifolds the gas lift line distributed to each production wellhead is isolated by a Gas Lift Valve (GLV) upstream of the choke valve. When the oil reservoir pressure becomes low the well head pressure is not sufficient to move the well fluid to the topside and the gas injection to the well head through gas lift line introduces the motive force to the well fluid to flow it out from the well head to the topside. There is a venturi flow meter in each gas lift line upstream of the choke valve for gas flow monitoring. Downstream of the choke valve there is an Annulus Master Valve (AMV) through which the gas lift line is connected to the annulus of each production well.
Gas lift line from the topside is connected to the 6" Gas Lift Swivel ( TU-FAS-0816) has the operating pressure 173.7 barg @ 70° C and design pressure 248.2 barg @ 38° C. From Gas Lift Swivel the gas lift riser No. 4 is connected to the subsea gas lift manifold North & South. The gas lift riser have the following operating & design conditions.

The following hot start-up procedure details the steps to be taken to re-start the Subsea flow line and riser system facilities following a system trip.
The procedure assumes all the facilities listed below have been operating normally but have shutdown as a result of a system trip or by manual initiation.
The reason for the shutdown has been investigated and rectified and it is considered safe to re-start the system.
The pressures, temperatures and flow within the Subsea system are at or near normal conditions.
The following conditions are assumed to exist in executing this procedure: -
No Permits to Work are in force on any part of the system that may prohibit, or hinder, the safe start-up of the equipment.
The Fire and Gas Detection System, ESD Systems and control facilities within the CCR are operational including all alarms, trips and controllers.
It is assumed that in a short duration shutdown it is unlikely that spades or blinds would be moved, or drain and vent valves opened unless required to take corrective action on the cause of the shutdown. It is therefore unnecessary to recheck these items other than if they have been disturbed.
All vents, purge points and manual sample points are closed and blanked, or capped off, where necessary.
Communications have been established between all the personnel involved with the start-up procedure.
Safety/Briefing Meetings have been held with all directly concerned parties outlining the workscope and procedures.
The following Utility and Ancillary Systems are available:
Electrical Power Distribution
Instrument Air
Hydraulic power
Booster gas compressors
Sea water lift and treatment
During the Hot Start-up of the Subsea System there should be no requirement to have any input over-ride to the to the shutdown system.
Note-1: This procedure assumes that the temperature of the system has not dropped significantly so there is no requirements to hot oil circulation.
