1 INTRODUCTION Framo Engineering AS started the development of the first multiphase flow meter in the late 1980’s with the first commercial deliveries in 1994. In 1998 Schlumberger and Framo Engineering AS merged their technologies and manufacturing expertise in the creation of a joint technology center, 3-Phase Measurements AS. Today the center draws upon the engineering and development resources of both organizations to provide multiphase metering technology development, equipment manufacture and support to Schlumberger and Framo Engineering’s service locations worldwide. The subsea PhaseWatcher Vx is a multiphase flow meter in the Vx meter product range from 3-Phase Measurements AS. The Vx meter uses the Vx Technology, where the main components are a venturi section, a high performance phase hold-up detection system and a multiphase flow model. Fabrication, assembling and testing is completed at Framo’s fabrication and test facilities at Flatøy (outside Bergen, Norway), which gives us a unique in-house control of the project. The subsea PhaseWatcher Vx multiphase flow meter can be packaged for subsea applications in various configurations to suit the client’s needs. For example, diver or ROV installation, a fully independent retrievable meter typically located on a manifold, or a meter as an integral part of a larger retrievable package within the tree envelope, typically; as a choke bridge solution offering a total retrievable unit. This document will give a description of this PhaseWatcher Vx and how it is interfaced in various subsea structures.

5 PHASEWATCHER Vx COMPONENT DESCRIPTION

5.1 IN-LINE PhaseWatcher Vx This section describes the component setup and how they interact with each other. The major components of the Inline PhaseWatcher Vx are (refer to Figure 6.1 below):

• Venturi section • Outer Cover • Transmitters • Gamma System • DAFC • Connector/penetrator

Venturi:

The venturi section assembly consists of the venturi section and the ceramic window assemblies. The functions of the venturi section are:

• To allow the process fluids to flow from inlet connection to outlet connection

• To contain pressure • To produce a differential pressure as a function of the venturi tube

profile

Outer cover: The venturi cover protects the venturi body and the electronics chamber from the environment. Its design is in compliance various project specific water depths and process temperatures.

Transmitters: High precision transmitters are used to measure the differential pressure, line pressure and process temperature of the system. The transmitters provide this information to the Data Acquisition Flow Computer (DAFC) which processes these signals. The transmitters are all redundant and placed in two separate pods on each side of the power and communication pod.

Gamma system: The dual energy gamma measurement uses a single natural isotope of barium; Ba133.The source strength is 370MBq = 10mCi. The Barium-133 gamma ray source emits photons at several energy levels. A SMART detector located on the opposite side of the venturi throat detects the gamma photons that have not been absorbed by the mixture and their energy level. A photomultiplier in the SMART detector converts the gamma photons into electric signals that are digitally processed.

6 MATERIAL SELECTION

The underlying principle of materials selection for the specific project will be optimized for life cycle costs, compatible with safeguarding the technical integrity of the subsea facilities. Design philosophy with regards to material selection is that all materials shall comply to NORSOK M001 and NACE MR0175/ ISO 15156-1,2,3. Evaluation of corrositivity in hydrocarbon systems shall as per NORSOK M-001 minimum include:

• CO2-content, • H2S-content, • oxygen content and content of other oxidizing agents, • operating temperature and pressure, • organic acids, pH, • halide, metal ion and metal concentration, • velocity, flow regime and sand production, • biological activity, • condensing conditions

The end user of the equipment (PW Vx ) is required to give this information to FE (manufacturer) for corrosion and sour service assessment of the primary pressure retaining bodies (process wetted parts) of the equipment. For all standard configurations of the PW Vx all process wetted parts (metallic materials) are selected in pre-qualified materials resistant to SSC/ SCC in the presence of sulfides to MR0175/ ISO 15156-2 or MR0175/ ISO 15156-3. Sour service (H2S presence) process conditions with high salinity, chloride concentrations and low in- situ pH are further restricted by the requirements given in Table 6 and Table 7 in NORSOK M-001. In other words the user shall define, evaluate and document the service conditions to which materials may be exposed – both intended and unintended exposures.

7 FUNCTIONAL PERFORMANCE DESCRIPTION

7.1 Principles of Measurements

The PhaseWatcher Vx is a three-phase flowmeter in the Vx range from Framo Engineering. The Vx range of multiphase flow meters uses the Vx Technology. Its main components are:

• a venturi section with pressure and differential pressure measurements • a high performance gamma phase hold-up measurement system • an integrated Data Acquisition Flow Computer (DAFC) • a three-phase flow model

The PhaseWatcher Vx is a complete and independent inline multiphase flowmeter, designed to measure three-phasic flow rates (Oil, Water and Gas). No other external inputs than fluid properties are needed. The PhaseWatcher Vx, together with a blind-T placed directly upstream, gives accurate and repeatable measurements independent of the upstream flow regime. The operating envelope is decided by the maximum acceptable pressure loss through the PhaseWatcher Vx, the minimum venturi differential pressure that can be measured with the required accuracy.

7.2 Flow Calculation

The velocity of the fluid flowing through the instrument is found using a venturi equation. For a mono-phasic flow we can find the flow rate using the dynamic signal of the dP transmitter together with the density of the fluid. However, for multiphase flow the equation is different, due to slip between the oil and gas. For a multiphase flow we need to know the total mixture density, before we can calculate the flow rates. To find this we use the output of the detector. Data from the detector is used to calculate the fraction of oil, water and gas.

7.2.1 Instantaneous fraction hold-up determination at the Throat of the Venturi

Calculations of oil, water and gas fractions are based on the attenuation of two different gamma energy levels of a radioactive isotope. The gamma-ray contains different energy levels, and the attenuation of two of these energy levels can by physical equations be expressed as a function of oil, water and gas hold-up. The attenuation of gamma rays is dependent of the density and the mass attenuation coefficient of the penetrated material, and the physical relation is well known:

Page 16: 650-6118-D Rev.A - Technical Description PW Vx Type B-E-G

Technical Description PhaseWatcher Vx Type B, E and G

DOC. NO: 650-6118-D REV.: 00 DATE: 20 Apr. 2010 PAGE: 16 of 22

N N eox= − ρμ

(1)

Where: N = count rate from the gamma detector

No = “empty pipe” count rate x = gamma path length ρ = density of the penetrated material μ = mass attenuation coefficient of the penetrated material

In the case where multiple components are penetrated, as in a homogenised mixture of oil, water and gas, equation (1) can be expressed as:

(2)

N = N0e -x[(μoρoαo) + (μgρgαg) + (μwρwαw)] The subscripts o, w and g in the above formula symbolizes oil, water and gas, and: αo = oil hold-up αg = gas hold-up αw = water hold-up x = path length = venturi throat diameter (D)

Since αo, αg and αw are the unknown, two more equations are required to solve the system. The dual energy gamma fraction meter utilizes the fact that radioactive sources emits radiation at different energy levels. The PhaseWatcher Vx utilizes two energy levels from a Barium133 source for the fraction measurements in multiphase flow. Equations similar to (2) are established for each of the two energy levels. The third equation used to solve the system is straight forward since the volume between the source and the detector is fully occupied by the mixture of the three fractions:

αo + αg + αw = 1 (100%) (3)

As seen from equation (2), the mass attenuation coefficient (μ) and the density (ρ) for each phase are used as input parameters (known values) in the fraction calculations. The mass attenuation coefficients are constants given by the chemical composition of a specific material (fluid). The mass attenuation coefficient for oil and gas (hydrocarbons) are not affected by pressure or temperature and are in most applications stabile over the field life. The density of oil and gas is given as functions of temperature and pressure. The properties (μ and ρ) of water are slightly dependent of salt content and may therefore change over time, or from well to well. Provided that the chemical composition of the water is known (as it in most cases due to regular sampling for PVT purposes), μ and ρ can be updated since they are input to the computer software. A re-calibration of the sensor is not required.

There is also a graphical way to find the three phase hold-ups. 100% oil, 100% water and 100% gas are shown in the diagram below as corners in a triangle. Detector count rate at energy level number 1 and 2 are given along the x- and y-axis respectively. Any combination of oil water and gas in the measuring section will give a point inside this triangle. The triangle is therefore called “the solution triangle”, refer fig. below.

Figure 3 – The solution Triangle

Gas hold-up (αg) and constant Water-Liquid-Ratio (WLR) can easily be drawn as seen in figure above. αg is read directly in the diagram while WLR is defined as

: WLR = αw/(1-αg)

It is important to emphasize that the dual energy gamma technology relies only on the attenuation of gamma rays. The attenuation measurements are completely independent of the distribution of the phases, whether the liquid is in an oil continuous state (typically 0-40% WLR), water continuous state (typically 70-100% WLR) or in the transition zone where emulsions normally are formed.

7.2.2 Density

The density for a phase is found using an algorithm based on input from a PVT analysis, together with raw measurement data from pressure and temperature transmitters.

7.2.3 Output Parameters

The following output parameters will be available from the PhaseWatcher Vx:

• Volumetric flow rates for water, oil and gas at standard and line conditions • Phase fractions for water, oil and gas at standard and line conditions • Total mass flow rate • Water liquid ratio • Gas volume fraction • Gas oil ratio • Basic sediment and water • Cumulative mass/volumetric values for oil, water and gas • Oil mass flow rate • Gas mass flow rate • Venturi differential pressure • Line pressure • Line temperature • Coefficient file selected

7.3 Performance

This performance of the PhaseWatcher Vx applies to meter measurements at line conditions. The flow rate performance applies to volumetric flow rates. These are typical performances that should be expected in the operating envelope. As the amount of liquid decreases in the flow, it is more difficult to measure the liquid accurately and the performance changes. This is why the meter performance is stated as a function of GVF. The performance is based on typical logging times of 15 minutes below 90% GVF and 20 minutes above 90% GVF. Please ref. document 4042-0015-D for full details on the guaranteed PhaseWatcher Vx performance.

7.4 Reliability

Framo obtains MTBF data for the PhaseWatcher Vx on a system level based on field experience (which is much more stringent than modelling according to MIL-HDBK 217-F). This exercise has already been performed and is presented in document 6101-4175-D Rev.00 “RAM Analysis for PhaseWatcher Vx Subsea”, which is the basis for the RAM (Reliability, Availability and Maintainability) analysis and reliability values obtained. This document shows that with the PhaseWatcher Vx operational experience the MTBF = 21.7 years. If all of the PhaseWatcher Vx subsea meters had been fitted with redundant instrumentation (DAFC and transmitters), in the same manner as for other projects delivered, the equivalent MTBF value would be greater than 30 years.

7.5 Redundancy Philosophy

7.5.1 DAFC

Two identical Data Acquisition Flow Computers (DAFC) are included in the redundant instrumentation.

Page 19: 650-6118-D Rev.A - Technical Description PW Vx Type B-E-G

Technical Description PhaseWatcher Vx Type B, E and G

DOC. NO: 650-6118-D REV.: 00 DATE: 20 Apr. 2010 PAGE: 19 of 22

The primary DAFC is activated and the backup DAFC is powered down (“sleeping”). Should the primary DAFC fail, then the backup DAFC is activated, while the failed DAFC is powered down. The Vx sensors (transmitters and gamma detector) may only be connected to one DAFC at the time. A relay board will by default connect the transmitters to the primary DAFC. If the secondary DAFC (DAFC B) is powered, then the sensors are automatically switched over to DAFC B.

7.5.2 Transmitters

All transmitters (differential pressure transmitter, line pressure transmitter and line temperature transmitter) are installed in identical pairs in such a way that both transmitters of each type obtain equally good operating conditions. All transmitters are being powered and operated simultaneously. It is hence possible to view and log data from both the primary transmitters (used for metering and flow calculations) and the backup transmitters at the same time. Should a primary transmitter fail, then the Vx setup file must be modified such that the backup transmitter becomes the new metering transmitter. The modification of the setup file is performed topside by an operator using the Service Manager application. When the modified file is uploaded to the Vx, the new setup is activated after sending a soft boot command to the Vx. Power consumption for HART transmitters in multidrop is very moderate; around 0.1 W per transmitter. Leaving all transmitters activated at all times will hence not contribute significantly to increased temperature in the instrumentation chamber or to deterioration of overall system life.

7.5.3 Gamma Detector

The current Vx design does not allow for more than one gamma detector and one barium source to be installed. The detector is automatically connected to the DAFC in operation.

7.5.4 Relay Board

A relay board is included in the redundant instrumentation. The purpose of the board is to make sure the transmitters and the gamma detector are automatically connected to the active DAFC. The board is a simple design consisting of a series of highly reliable monostable relays. The relays interface the Vx sensors with the DAFCs. The relay control voltage is generated by power B/DAFC B. As long as DAFC B is not powered, all relays are in their passive state connecting the sensors to DAFC A. Powering DAFC B will activate the relays and sensors are automatically switched over to DAFC B.
