An Early Bird delegate rate of £ 170 (+ VAT) for PPSA members and £ 250 (+ VAT) for non-members applies for payments made before 14th October. After 14th October the price is £ 210 (+ VAT) for PPSA members and £ 290 (+ VAT) for non-members.

Presentations include:

    Removal of wax/sand from carbon steel pipe work using ice slurries (ice pigging)
    Presented by Steve Wheeler, iNPIPE PRODUCTS

      Ice Pigging is a pipe cleaning technique, mature in the water / wastewater industries currently being developed for the oil and gas industry. A high-solids ice slurry is pumped under pressure to deliver a wall shear stress on the pipe, cleaning it through physical abrasion. Made of just water and salt, ice pigs do their cleaning, unblocking, debris entraining and transport before melting back into just water; offering a physical clean thousands of times more effective than flushing, without chemicals or risk of getting stuck.

      The set of trails, which is the focus of this paper were Funded by Shell UK with the aim of understanding how effective ice slurries are at removing waxes and sand from ‘real world’ diameter hydrocarbon carrying, carbon steel lines.

    MFL results like a Laser Scan – taking analysis of complex corrosion and pinholes to the next level
    Presented by Michael Rapp, ROSEN Group

      3D laser scans are becoming more popular for field verifications and pipeline operators are demanding a corresponding ultra-high resolution inline inspection technology, which could refine integrity calculations. Ultimately this would lead to improved pipeline safety, while simultaneously reducing the need for costly field verifications.

      Hence, an ultra-high resolution MFL technology with sensor spacing similar to that of a 3D laser scan has been developed.

      To provide reliable inspection results using a ultra-high resolution MFL measurement system a series of challenges had to be overcome:

      • The extremely tight track spacing requires continuous data recording without any gaps in circumferential direction. This calls for accurate mechanical design to ensure each sensor stays exactly in its track, especially when passing welds.
      • There can be a significant impact on the recorded data quality, due to sensor placement on the yoke in relation to the magnetic field. Specific normalization efforts are required to ensure a uniform appearance of data for subsequent evaluation.
      • The sheer amount of inspection data generated warrants the use of machine-based learning algorithms in data evaluation, reducing the ‘human factor’ impact.

      Next to presenting solutions for the above listed technical challenges, this paper will also provide an insight into how pipeline integrity management will benefit from ultra-high resolution MFL inline inspection results.

    World first pressurised subsea pipeline repair facilitated by a combination of non-piggable and piggable isolation tools
    Presented by Dale Millward, STATS Group

      A case study will be presented highlighting how a recent pipeline repair project was executed without depressurising the entire 780km 28” gas export pipeline.

      The presentation will explain how the damaged pipeline was initially isolated, using a hot tap installed double block and bleed line-stop tool. It will then describe how the remote controlled piggable isolation tools were deployed into the pipeline using a temporary flangeless subsea launcher so the ‘pressurised’ pipeline could be recovered onto a pipe-lay vessel to install a new section.

      The sequence of how the double block and bleed isolation tools were fully proved in-situ will be described, including further explanation of the verification testing sequence. Verifying that two separate fully proved leak-tight barriers with a zero-energy zone between them was in place, before any breaking of containment took place ensured compliance with subsea isolation guidelines.

      Actual worksite photographs, subsea video footage and animations will be used to show how this complex and challenging pipe repair was safety and successfully completed.

      Case Study Highlights:

      • High criticality pressurised subsea isolation of a 28” gas export pipeline in the South China Sea “Kept the lights on in Hong Kong”
      • World First: First time BISEP™ technology has been deployed subsea offering highest level of pipeline isolation in the industry.
      • Utilising proprietary technologies the Tecno Plug™ (piggable) and BISEP™ (unpiggable) isolation tools (DNV GL Type Approved).
      • Damaged subsea pipeline due to anchor drag incident, unpiggable pipeline isolated by subsea hot tap installed isolation tool (BISEP™)
      • Piggable isolation tools deployed subsea utilising STATS Flangeless subsea launcher – offering bare pipe connection, without the need for hyperbaric welding.

    Pig motion and dynamics in complex gas networks
    Presented by Dr Aidan O’Donoghue, Pipeline Research Limited

      A model to examine pigging and inspection of gas networks with multiple pipelines, connections and customers is presented in this paper. A case study with a typical gas system with multiple lines, connections and off-takes is also presented to demonstrate the use of such a model for planning and executing real life operations. A gas flow rate is provided into the network to the various users of the network or grid. Each customer has a requirement for both a minimum pressure and a minimum flow that cannot be disrupted without penalty to the operating company. Additionally, inspection or ILI tools must be run within certain velocity constraints to allow reliable data to be achieved. Due to the complexity of the system, there is a risk that the pig could stall in the line as flow is diverted as a result of the pigs own differential pressure. Manipulation of valves and flows must be planned and performed carefully so as not to disrupt the demands of the various customers in the network. Excessive pressure drop across valves is undesirable if they are to be opened during the operation. Pigging the system is onerous due to the need to balance the requirements of the pigs and the demands of the customers. The pig run time or expected arrival time with transient events such as valves opening, changes in flows, disruption to customers and other transient events is calculated. The paper presents the model and its use to optimise pigging programs in gas networks.

    Introduction to ultrasonic in-line inspection of CRA pipelines
    Presented by Herbert Willems, Gerhard Kopp, NDT Global GmbH & Co. KG

      Pipelines manufactured from corrosion-resistant alloys (CRA) are becoming more common in special applications, in particular with offshore pipelines which are in many cases exposed to a harsh and highly corrosive environment. For many years the inspection of CRA pipelines (solid CRA, clad and lined pipe) was not a high priority. Due to the special composition of these types of line pipe it also posed specific challenges to in-line inspection methods as compared to the inspection of common line pipe.

      In this article, the different types of CRA line pipe and the relevant characteristics regarding in-line inspection (metal loss inspection, crack inspection) are described. Typical damage mechanisms (e.g. pitting corrosion) that may develop during operation are illustrated and the specific capabilities that are available for ultrasonic in-line inspection as well as the limitations are explained. Several examples from inspection runs in CRA pipelines are presented demonstrating that reliable in-line inspections with good data quality are feasible to a wide extent.

    Congo River Crossing (CRX) pre-commissioning
    Presented by Michael Bowes, Halliburton

      The CRX pipeline was built to bring associated gasses from various fields to an LNG Processing Plant in Soyo, Angola. The pipeline runs a distance of ~140km from the processing plant to the South Nemba Platform located offshore Cabinda via two satellite pigging platforms (NPP & SPP) which provide the location for the drilled conduit which crosses the Congo River.

      Halliburton were contracted to perform pre-commissioning services on each Segment independently (flood, clean, gauge, caliper survey, hydrotest) before the close in spools and subsea structures were installed.

      Once all segments were completed and tied in a global leak test was conducted prior to commencing dewatering operations. Each segment was bulk dewatered followed by final dewatering and vacuum drying before being packed with nitrogen in preparation for first gas.

      During the various campaigns each Segment had its own incidents/problems ranging from stuck centraliser tools, leaking hot stabs, vessel delays etc. resulting in major delays to the overall project. The Pre-commissioning was successfully completed in early 2016.

    Online pigging tool management system
    Presented by Pipeline Engineering & Supply Co. Ltd

      Pipeline Engineering opened a Service Centre within the city of Aberdeen, Scotland in 2008 to offer a pigging tool management and tool refurbishment service to the North Sea Pipeline Operators for their routine pigging tools.

      Routine pigging tools are used by the pipeline operators to carry out maintenance cleaning operations within the production pipelines without impacting on production flow or revenues.

      The Aberdeen Service Centre receipts the pigging tools from the customer post run, and then conducts a full service which comprises of cleaning, stripping, inspection, spares replacement, refurbishment, and final testing. The pigging tools are then ready to be utilised on another routine cleaning run.

      Once the pigging tool has been fully serviced, a detailed refurbishment report is submitted to the customer, providing the customer with visibility on the pigging tools condition and information of the service work carried out by Pipeline Engineering. This pigging tool management and tool refurbishment service has helped the customers make large savings on their annual pigging tool costs, whilst also receiving the required engineering expertise to optimise their pigging operations.

      The Aberdeen Service Centre has a pigging tool tracking system in place for each customer which highlights their full pigging tool fleet location, condition, configuration, last test date, run details, GA details etc. This system method was previously submitted to the customer on a weekly basis, along with a summary report of all activities. The customers used this system on a regular basis to monitor their pigging tool logistics, and to also advise the platform personnel on what the next pigging requirement were to be.

      In Q3 of 2016, Pipeline Engineering will be upgrading their pigging tool management service to their customers by introducing an Online Pigging Tool Management System. This online management system, with a personalised customer log in, will help each customer improve visibility of their pigging tool fleet whilst providing the option to remotely access the data via a mobile phone or tablet app. Having such up to date data at hand reduces the customers and/or platforms time spent sourcing the required information via the previous method of emails or saved folders.

      The online management system will also give the customer the advantage of viewing GA drawings by simply clicking on the GA drawing identification number. Once visible, the customer has the further option to print, copy to email, and/or forward on.

      As the Oil and Gas industry operates 24/7, Pipeline Engineering has created an excellent solution to provide continual all year support to the pigging industry.

      This paper will describe the optimisation process for cleaning tool maintenance via some customer case studies and also demonstrate the software functionality and describe the benefits of having the data at your fingertips.

    Advances in MFL signal matching and corrosion growth rate selection
    Presented by Andy Russell, ROSEN Group

      The safe operation of pipelines carrying corrosive products or in a corrosive environment, requires an understanding of the corrosion threats, the ability to monitor the growth of corrosion features; and estimates of the rate of degradation for planning future inspections, repairs and replacements. Reducing uncertainties in corrosion behaviour will result in safer more cost efficient operation. This paper will provide:

      • An overview of methods used in the industry for estimating corrosion growth rates (e.g. coupons, corrosion modelling, population comparisons, feature matching and signal matching).
      • The challenges of MFL signal matching and how advances in pattern recognition and data pre processing now allow full automated matching of signal level data from repeat inspections.
      • A comparison of different ways of using corrosion growth rate data (e.g. feature specific rates, spool rates, maximum rates, segment rates, upper bound rates, average rates) and how to select the best method, to ensure safety while minimizing repair and reinspection requirements.
