Dana’s Triton FPSO is located in block 21/30 approximately 120 miles east of Aberdeen, and produces oil and gas from the Bittern, Clapham, Pict, Saxon, Guillemot West and North West fields.

Triton is Dana’s first major operated asset in the UK, it consolidates the company’s strong position in the Central North Sea and is a core part of their strategy to acquire more operated positions where there is a strong commercial and operational rationale to do so.

Customer:Apache Corporation
Project:Beryl Alpha Platform Xmas Tree Valve Upgrade
Location:North Sea UK Sector
Products:ABLE v-Trakka Valve Position Transmitter

Having successfully furnished several of Apache’s other UK North Sea assets (inc. Beryl Bravo & Forties Charlie & Delta) with the innovative, in-house developed v-Trakka Universal Valve Position Indicator, ABLE have now been commissioned to retrofit this innovative device to the Xmas tree valves on the Beryl Alpha Platform.

The v-Trakkas will be replacing pressure transmitters installed on the valve hydraulic lines, the accuracy and reliability of which has been compromised by regular blockages necessitating intensive maintenance. Conversely, once fitted, the v-Trakka requires minimal attention.

Having successfully furnished several of Apache’s other UK North Sea assets (inc. Beryl Bravo & Forties Charlie & Delta) with the innovative, in-house developed v-Trakka Universal Valve Position Indicator, ABLE have now been commissioned to retrofit this innovative device to the Xmas tree valves on the Beryl Alpha Platform.

The v-Trakkas will be replacing pressure transmitters installed on the valve hydraulic lines, the accuracy and reliability of which has been compromised by regular blockages necessitating intensive maintenance. Conversely, once fitted, the v-Trakka requires minimal attention.
The v-Trakka is a compact, lightweight mechanical instrument suitable for installation in the harsh well environment. The 316 st/ st cover and rigid base provides significant protection from dirt and everyday impacts. The cover also provides added safety by preventing personnel from standing in front of the valve stem. The high-viz position marker can be viewed through the toughened-glass window slots.
Apache continue to standardise on the v-Trakka across their various assets with several hundred now installed across the Beryl and Forties fields.

Many operators no longer use limit switches for control of Xmas tree valves as they are considered unreliable and unsuitable; limit switch technology only provides valve status as fully open or fully closed with no continuous feedback.
To compensate for this, an alternative method has been to infer the position of the valve by trending the pressure in the hydraulic lines. However, accuracy of the pressure measurement versus valve position is poor, as is reliability, due to transmitter blockages that require maintenance.

The consequences of incorrect valve position control can include process failures, shutdown and most importantly impact on a safe working environment. Such loss of production can incur massive costs.

For a continuous direct valve position measurement, ABLE have developed a universal valve position transmitter (v-Trakka) which can be retrofitted to most leading types of surface Xmas tree valves to provide an accurate and repeatable 4-20mA output correlating to the actual physical valve position.

Once installed, the v-Trakka requires no maintenance. The v-Trakka is a compact, lightweight mechanical instrument suitable for installation in the harsh well environment. The 316 st/ st cover and rigid base provides significant protection from dirt and everyday impacts. The cover also provides added safety by preventing personnel from standing in front of the valve stem. The high-viz position marker can be viewed through the toughened-glass window slots.

In order to facilitate installation across the myriad of Xmas tree valve designs v-Trakka is available in two variants. Model VT1 for continuous direct valve position measurement on valves that have a central stem and Model VT2 for applications involving top side trees that use the indicator window design.

ABLE Instruments presents the ABLE v-Trakka Christmas Tree Valve Position Transmitter. Secured directly to the valve collar and strong enough to withstand a scaffold pole knock, the v-Trakka also has a 316 stainless steel quick fit cover with viewing windows.

It is very easy to fit and simple to set up and provides protection from muck, physical damage and worker injury (by being in front of valve-stem).

Features:

  • 360° sensor allows for any stem rotation
  • 2-Wire EEx d Loop-powered Transmitter
  • Continuous Direct Measurement of Tree Valve-position
  • Universal Design; Retrofit to most common surface-trees, including:
    • Cameron
    • Baker-Hughes
    • Vetco
    • Safoco
    • Wood Group
    • Presco-Dyne
  • Extremely stable and robust design eliminates dependence on problematic limit switches and inferred pressure measurements.

Customer:Nexen
Project:Buzzard Phase II
Location:North Sea UK Sector
Products:V-Cone Flow Meter

Located about 96 km northeast of Aberdeen in approximately 96 m of water, the Nexen-operated Buzzard platform is the largest UK North Sea oil discovery in the past two decades. BPII is a subsea development of the Buzzard northern area. The objective of this project is to safely develop additional reserves and bring new production on stream, supporting the goal of maximizing economic recovery in the North Sea.

The selected concept is a subsea development of the Buzzard northern area, approx. 5km NE of Buzzard consisting of a 12-slot manifold (eight production slots and four water injection). The development will be tied back to the existing Buzzard complex with a pipeline bundle assembly incorporating pipelines, manifolds, subsea controls and chemical injection. A brownfield module is to be installed on the production platform for processing and export via current export pipeline routes.

WorleyParsons UK, who are providing EPC services for the topsides module, including module fabrication, brownfield scopes, module landing preparation and the associated tie-ins, approached ABLE Instruments for a V-Cone Flow Meter for deployment on the Slugcatcher Gas Outlet Flow. In view of the high levels of corrosive and toxic agents in the process (H2S, CO2, Hg) the meter is to be manufactured in Super Duplex.

ABLE have a strong supply legacy with the Buzzard assets, having equipped the original platform with the nucleonics and allocation metering packages.

Customer:Cammell Laird Shiprepairers & Shipbuilders Ltd
Project:RRS Sir David Attenborough
Location:Birkenhead
Products:Miscellaneous level switches & gauges, temperature & pressure switches & transmitters, moisture in oil monitors.

The RRS Sir David Attenborough is a vessel owned by the Natural Environment Research Council which will be operated by the British Antarctic Survey for the purposes of both research and logistic support. The ship is intended to replace a pair of existing vessels, RRS James Clark Ross and RRS Ernest Shackleton. The vessel is named after famed broadcaster and naturalist Sir David Attenborough.

The first steel for the construction of the ship was cut in July 2016. The keel laying ceremony for the ship, yard number 1390, took place on 17 October 2016.

Cammell Laird, the shipbuilding contractor responsible for the vessel’s construction, commissioned ABLE Instruments & Controls Ltd for the supply of a diverse instrument package to equip the Sir David Attenborough with a range of pressure and temperature switches and transmitters for critical pump & compressor protection duties, instrument air and cold room monitoring. ABLE are also supplying a variety of level controls for waste water tanks, drain tanks, expansion tanks and settling tanks, and some high end moisture in oil detectors for measuring water in fuel and lube oils.

The ship will be constructed by combining individually fabricated blocks, much like the Queen Elizabeth-class aircraft carriers. The majority of the blocks will be manufactured by Cammell Laird at Birkenhead, but due to a tight schedule, the stern of the ship (named ‘Block 10’) was fabricated at the A&P Group on the River Tyne. The section was transported to Merseyside on a barge in August 2017. The stern section was loaded onto the barge by heavy lifting company ALE, using self-propelled modular trailers (SPMT). The same procedure in reverse was then used to get the hull segment on to the slipway at Birkenhead. The hull of Sir David Attenborough was named by her namesake and launched on 14 July 2018. She was moved into a wet dock for the addition of her superstructure and fitting out. The ship is scheduled to be completed by October 2018.

RF Admittance is a tried and tested solution to the fly ash level measurement application and has been an industry standard for coal fired power stations. Remote electronics negate potential problems associated with this harsh environment and Drexelbrook’s proven Cote-Shield technology ignores coating build-up on the probe.

Customer:BP
Project:BP West Nile Delta Gas Development Project
Location:Egypt
Products:Miscellaneous Workshop & Field Calibration Equipment

BP announced in May 2017 that it has started gas production from the first two fields, Taurus and Libra, of the West Nile Delta development in Egypt. The project was delivered eight months ahead of start-up schedule and under budget. First gas was exported to Egypt’s national grid on 24 March 2017 and the commissioning of all nine wells of the development’s first two fields and ramp up to stable operations has now been completed.

The West Nile Delta development, which includes five gas fields across the North Alexandria and West Mediterranean Deepwater offshore concession blocks, is being developed as two separate projects to enable BP and its partners to accelerate gas production commitments to Egypt. When fully onstream in 2019, combined production from both projects is expected to reach up to almost 1.5 billion cubic feet a day (bcf/d), equivalent to about 30 per cent of Egypt’s current gas production. All the gas produced will be fed into the national gas grid.

ABLE Instruments & Controls Ltd were contracted by Bechtel International to supply a diverse package of workshop and field calibration equipment ranging from handheld manometers to portable dew point monitors and encompassing loop calibrators and potable water test kits.

Following final approval in 2015, development of the first project, involving the Taurus and Libra fields, was fast-tracked to enable delivery of an annual average of more than 600 million standard cubic feet of gas a day (mmscf/d) to the Egyptian national gas grid. The fields are currently producing more than 700mmscf/d sales gas and 1000 barrels per day (bbls/d) condensate which is 20% higher than the planned sales gas plateau.

The Taurus and Libra project is a subsea greenfield development including nine wells (six in Taurus and three in Libra) and a 42 kilometre tie back to the existing onshore processing facility where gas enters the Egyptian national gas grid via a nearby export pipeline.

This is the second of seven major upstream projects that BP expects to come into production during 2017. Together with the projects that began production in 2016, these new start-ups are expected to provide BP with 500,000 barrels equivalent a day (boe/d) of new production capacity by the end of this year. With further new projects starting up beyond this, by the end of the decade BP’s new projects are expected to have added 800,000 boe/d of new production.

The nearest residential properties are just under 300m away to the east and persistent complaints regarding the characteristic “bad egg” odour associated with hydrogen sulphide (H2S) pervading the local neighbourhood lead to threats of prosecution from the Surrey Heath Borough Council. Consequently, in order effect rapid detection and elimination of these odours, Thames Water have procured from ABLE Instruments several of the venerated Jerome J605 H2S Analysers in environmental housings for fixed point monitoring as previously, successfully implemented at Thames’ Mogden and Acton STW sites.

The analyser systems have been located at the site perimeter and in key process areas such as aeration lanes and around settlement tanks. As opposed to a hard-wired interface with the site SCADA system, Thames Water have deployed Isodaq’s Frog Loggers for capture and wireless transmission of the data from the Jeromes. This will be monitored by the Innovations and Compliance teams.
