38 Measurement and Testing SCADA System Order Received for Gas Distribution Pipeline Project in Bangladesh

Yokogawa Electric Corporation (the Netherlands) have announced that Yokogawa India has received an order from the Gas Transmission Company Limited (GTCL) to supply a monitoring and control system for the gas pipeline system in Bangladesh. This project will involve the revamping, modernisation, and expansion of GTCL’s existing supervisory control and data acquisition (SCADA) system.

GTCL owns and operates a network of pipelines for the nationwide transmission of gas from gas fields that are primarily concentrated in the eastern part of Bangladesh. GTCL is planning to build an integrated SCADA monitoring and control system that will ensure the stable and efficient supply of gas to three of the country’s eight administrative divisions: Dhaka, Chittagong, and Sylhet. GTCL plans to increase its gas transmission volume to 550 million standard cubic feet per day (MMscfd), up from 400 MMscfd in 2013.

This order is for FAST/TOOLS SCADA software and a STARDOM network-based control system for pipeline monitoring, DPharp EJA and DPharp EJX series differential pressure/pressure transmitters, other field instruments, a closed-circuit television (CCTV) system, and a telecommunications system for central monitoring and control. Targeting delivery within 22 months, Yokogawa will be responsible for the engineering, installation, and commissioning of these systems.

Yokogawa proposed a bespoke automation solution which was selected because of Yokogawa’s reputation for quality and extensive experience in supplying SCADA systems for oil & gas pipeline projects.

Tsutomu Murata, managing director of Yokogawa India, commented “I am honoured to receive this order, which is Yokogawa India’s largest project to date in Bangladesh. By carrying out this large project, we aim to help ensure a stable energy supply for the people of Bangladesh.”

In accordance with its Transformation 2017 mid-term business plan, Yokogawa is strengthening its efforts to drive up sales by providing solutions for pipelines and other oil & gas midstream applications. Encouraged by its success in winning this order, Yokogawa plans to expand its control business in the midstream applications segment.

Inline Viscometers to determine Rheological Properties of

Drilling and Fracturing Fluids Brookfield Engineering Laboratories, Inc. (USA) has successfully provided its PVS pressurised rheometer to leading pressure pumping operations in Canada. The PVS and TT-100 inline viscometers were on display at Global Petroleum June 9-11, 2015.

Well fracturing operations require proper rheology of the fracturing fluid. To optimise fracture operations, the fracturing fluid’s viscosity must be high enough under low shear conditions to suspend and carry proppant to the smallest crevices in the fractured rock. In addition, its viscosity must be low enough under high shear rates so that adequate flow to these newly fractured strata is obtained and the proppant is released.

Designed to address any application in single and multispectral analysis, FLIR SC7000 Series cameras offer researchers a choice between mid-infrared Indium Antimonide (InSb) as well as mid-infrared and longwave infrared Mercury Cadmium Telluride (MCT) detectors. In addition the FLIR SC7000 series comes standard with a removable, motorised 4 position filter wheel enabling high performance imaging of events in a select part of the electromagnetic spectrum.

The SC7000 series can produce high quality infrared imagery in 640 x 512 or 325 x 256 pixel formats with high sensitivity and noise levels as low as 20 mK. Windowing allows a subset of the total acquired image to be selected with user adjustable window size at frame rate speeds of up to 62,000 Hz. Camera integration time on the SC7000 Series is adjustable in nanosecond increments. This smart external triggering feature allows synchronization of the image capture to the most fleeting events.

Benefiting from FLIR’s proprietary Hypercal technology, SC7000 series cameras are able to ensure the most accurate temperature measurement with the highest sensitivity. Simply set the desired lower and upper temperature limits and the camera will automatically adjust to the appropriate integration (exposure) time.

Leveraging FLIR unique Superframing technique enables SC7000 Series camera users to sequentially acquire thermal data from up to four user-defined temperature ranges, and then merges those streams into a single real-time video that spans all four temperature ranges, effectively extending dynamic range from 14-bit to 16-bit.

CNUC is a proprietary FLIR calibration process that provides unmatched high quality imagery and measurement stability on SC7000 Series thermal imaging cameras. CNUC allows flexible integration time adjustments without the need to perform non-uniformity corrections. CNUC calibration also produces accurate measurement stability regardless of camera exposure to environment variations.

The FLIR SC7000 Series thermal imaging camera works seamlessly together with FLIR ResearchIR Max software enabling intuitive viewing, recording and advanced processing of the thermal data provided by the camera.

As part of the laboratory development of the fluid, its rheology must be measured, evaluated, and understood over the majority of shear rates likely to be experienced at the well site so that an understanding of the fluid’s behavior is known before it is pumped through the system. This requires an easy to use computer based, software driven rheometer, like the Brookfield PVS, that measures viscosity under pressure, and in addition provides the means to test at different shear rates, time spans, temperatures, pressures, and provides data analysis and data recording capabilities.

The TT-100 inline viscometer provides real-time, in-line measurements for gels moving in pressurised lines from the hydration unit before being pumped down-hole. It will continuously verify, at the well site, that the rheology of the fracturing fluid is within established specifications and provide an alarm indication when it is not, thus providing the means for precise, real time, viscosity control along with a complete and accurate record of the fracturing process. The result is reduced costs, less wear on equipment, and lower risk of damage to the formation.

The AFRISO (Germany) NS 100 (NS 160) is used to measure the pressure of gaseous and liquid media at temperatures of up to 150 °C in the measuring ranges 0/0.6 bar to 0/1000 bar (0/0.6 bar to 0/1600 bar). The robust design with a measuring system that is completely welded to the housing results a shock- and vibration-resistant unit that does not require seals. This keeps the risk of leaks to a minimum and ensures high long-term stability. The pressure gauge features bottom or back bottom process connections G½B – AF 22 (EN 837-1/7.3). Other, customer-specific process connections are also possible. The Bourdon tube pressure gauge for chemical applications is made of stainless steel 304 and tightness-tested with helium; it features laminated safety glass window and a blow-out. The pressure gauge is optionally available with a back flange, a panel mounting bezel, a 3-hole fixing, panel mounting bezel, special scales, electrical contacts and an ATEX version.
