P2D is a rapidly expanding technology company with design, research and operations centres based in the North of England and Scotland. Using a range of ATEX certified technology P2D offer services to pipeline operators in the UK North Sea, for assessing pipeline condition and providing and managing remedial solutions;

• Quantify the thickness, distribution and potential volume of pipeline debris along the entire length of pipeline.
• Provide a detailed operational and geometric profile of a pipeline
• Evaluate the efficiency of production cleaning pigging strategies with regard to pig type and run frequency
• Evaluate the effectiveness of chemical cleaning programs
• Evaluate the performance of standard and or specialized cleaning pigs
• Develop “intelligent cleaning” programs whereby routine measurement of actual pipeline conditions can be used to optimise pipeline cleaning strategies.
• Evaluate the efficiency of pre-inspection cleaning programs, before, during and after implementation
• Provide a “Go/No Go” indicator ahead running an III tool
• Assess the pipeline internal condition before developing a de-commissioning campaign

Gas or fluids bypass through the annulus of the pig’s body and through variable ports in the front and sides of the pig’s nose.  The on board computer, reacting to input from odometer wheels, regulates vane position and therefore the amount of bypass. As more bypass occurs, speed is controlled relative to line velocity, within pre-determined parameters.

The electronics package includes a  P2D P.E.T.data logger,  which records vane position, differential pressure, temperature, X,Y,Z orientation and other vital data that confirms the behavior of the pig,.

42” and 36” tools were recently run in 5 sections of high velocity gas lines.  These lines operate under a special 80% SMYS rule and slowing down throughput to perform required maintenance cleaning costs the operator a substantial loss of revenue.  On a recent 56 mile, 36” run, gas flow averaged 12 mph and the SCP maintained a speed of 5 – 6 mph with the bypass vane system opened at 50%.

The SCP has the ability to tow ILI tools at speeds that will allow more reliable data to be recorded.  The pig can also be used as an enhanced cleaning tool on lines that have black powder.  The bypass moving thru the pig exceeds the entrainment velocity of the debris, and assists in suspending the material out in front of the pig.
