interfacing between suppliers, one documentation

package,

One supplier for installation and commissioning

services

After Installation

One supplier for spare parts

One user interface, less personnel training for

operations and maintenance.

Healthcare and maintenance contracts.


Why Internal Corrosion Monitoring?

Corrosion Management

• Correlate process parameters with measured corrosion

• Monitor (change in) corosivity of pipeline fluids

• Control of corrosion mitigation/inhibitors

• High resolution and fast response required from the sensor.

Integrity management and safety verification

• Risk of unexpected failure and accidents

• Avoid loss of containment

• Optimize (risk based) inspection programs and planned maintenance

• Reliable wall thickness measurements over time required, high resolution/fast response less important.

CorrLog™ Logging Instrument


Continuous, off-line monitoring

CorrLog instrument hooked up to one probe for continuous measurement

Can use up to 20 meter probe cable – flexible installation

Reads ER/LPR/Galvanic probes from most manufacturers

Data collection to MultiCorr MKII terminal or ATEX palmtop terminal for transfer to MultiTrend software

Minimum energy consumption - use 3 x AAA Duracell batteries for long term performance (battery life depends on measurement frequency)

High accuracy – high resolution

Can easily be upgraded to on-line configuration (replace interface board)

Allows continuous corrosion monitoring at a low installation cost.


Continous on-line Monitoring - 4 –20 mA

Online 4-20mA analogue signal

– Battery free version

– Maintenance free

– Ideal for extreme climates

– Monitors continously

– Transmit latest reading

– Sensitivity of 4-20 mA transmission: 125 ppm

Combined Terminal/4 –20 mA version

– Batteries and sensitivity as for stand-alone unit

– Sensitivity for terminal as for field bus system

– MultiTrend used for data presentation of terminal collected data


Continous, on-line Monitoring - FieldBus

On-line monitoring- FieldBus system

Minimum personnel need –

remote control - data directly to

control room or on-shore offices

Immediate information – allows

alarm settings in control system

Continuous data

Accurate trending

Accurate correlation with

process data

Automatic operation – no

problems caused by operator

error


Offshore Platforms - example


Field example – online CorrLog


Why Sand/Erosion Monitoring


Sand Erosion Sensor

• ER elements face flow at optimum angle

• Measures erosion directly

• Superior sensitivity (+/-5 nanometers or 0.0002 mils)

• Reference element in protected location (rear)

• Multiple elements for redundancy & coverage of entire pipe

diameter

• Operates in all flow regimes


SandLog™ Data Logger

• Power supply: via fieldbus master

• Minimum measurement interval:

2 minutes

• Sensitivity: 10 ppm of probe

element thickness

• Operating temperature:

-40 deg.F – 160 deg.F

• Eex ia approved to ATEX & NRTL

requirements

Sand Monitor Sand Monitor – Topside Applications

Clamp-on sand detection system with a non-intrusive design

Based on acoustic technology (Utilizes the acoustic noise

generated by sand particles impacting the inner surface of the

production pipework to identify and calculate real-time sand

production in any water, oil, gas or multiphase pipeline flows)

High sensitivity

All data processed internally & stored in flash memory

Local status display (LED)

No need for a computer in daily use

Sand Monitor - Subsea

Provides real-time quantitative monitoring of sand in the production

flow

Based on passive acoustic technology

Maintenance free

Low power consumption

Two-way communication

Functional error checking

Combining erosion based and acoustic systems

Redundancy – two alternative measurement principles

Best of two worlds

– Acoustic -> immediate response on sand changes

– Intrusive -> ”direct erosion measurement”, quantifies sand when combined with flow rates

Improved alarm settings

Trend towards using both acoustic and intrusive sensors

Can be integrated in one Roxar Sand Management system, using same Fieldwatch software.

Choke Position [%] Sand Rate


• Sand/erosion data used for determining

maximum sand free rate.

• Production rate increased until sand

production starts, then flow rate reduced

until acceptable sand free level

• Sand burst detected from sand data

• Well choked back until sand production stopped

• Sand burst detected after minutes – incident under

control

• Accumulated metal loss of 5.2 µm

• Metal loss during sand burst corresponds to 10

mm/year risk to well and infrastructure

Application Description Sand Management System, Offshore N.Sea

• Production optimization and integrity control

• Platform serves multiple clients

• Increase confidence in alarms to drive

speed in optimization process

• Manage changing conditions as reservoir

produces higher watercuts and gas fractions


Customer Value

• Completely integrated system with 80+ sensors
