IN-LINE INSPECTION (ILI) TOOL DESIGN
From working within the Oil & Gas industry, D3 specialize in the mechanical design of pipeline inspection tools. We can assist with all aspects of the design, including:
Pressure Vessel design for housing Batteries & Electronics
Specification of sealing elements
Suspension assemblies
Odometer designs
IMU Mapping
Transmitter & tracking device integration
Towbar design
Sourcing and specification of Subsea connectors & harnesses
In Summary, full Mechanical design to ensure the tool can navigate any pipeline.
D3 is home to over 250 years of combined experience in PIG design and have helped a number of clients develop a wide range of tools using various sensor technologies, such as Magnetic Flux Leakage (MFL) and Electro-Magnetic Acoustic Transducers (EMAT) as well as many others ranging from 6 to 56” diameters. We know what to look out for in PIG design having experienced a number of challenging projects in the In-Line Inspection industry including:
Multi-Diameter
Vertical Launch
Wye Passing
Clapper Valve Protection
High Line Pressure
Tight Bend Radii
Onshore and Offshore Launch/Receive
High Flow-rate
Handling Equipment
D3 have also supported the operation and maintenance of PIGs by designing specialist handling equipment such as launchers and manipulator frames, all of which is done to a strict quality in accordance with the relevant codes and standards. We can design & help with the following:
Launcher & receiver systems - hydraulic or chain drive
Cassettes for PIG retrieval
Handling Tray
Pusher Poles & trays
Lifting Cage
Lifting or Pull-out wire/rope
Manipulators
Site Surveying and in-line inspection
Site surveys are crucial to this industry. Time is money, and any difficulties unforeseen early in the early stages will set back projects or even stop completely. Our engineers have had first-hand experience carrying out these surveys to make sure the tools are capable of working under the conditions.
REVIEW OF PIPELINE INFORMATION
Having the uncertainty of problems and failures occur in oil and gas lines can trouble anyone. At D3, we have the experience to review the information provided and consult you on all matters involving this line of work.
Here of some of the aspects, we can review:
Pipeline operating conditions and suitability for inspection
The suitability of launch and receive traps.
The client procedures for pigging
Availability of cleaning and inspection pigs
Using the information provided we can:
Populate a pipeline questionnaire with the available data.
Determine whether a line is suitable for running cleaning and/or inspection pigs.
Specify requirements for cleaning and inspection pigs.
Once we have fully carried what is required, a report can be published detailing the findings of the study.
