Riser Identification Program
Riser Identification Program2015-2017Columbia Gas of Pennsylvania ColumbiaGasPA.com
What prompted identification of Field Assembled Risers? Polar Vortex a few years ago– Found multiple leaking risers on customer owned facilities– Identified the types of risers as Field AssembledColumbia Gas of Pennsylvania ColumbiaGasPA.com 2
Establishing a Plan How are we going to capture the Data? Who is going to perform the work? What is the timeframe to have all risers identified? What is the plan for remediation?Columbia Gas of Pennsylvania ColumbiaGasPA.com 3
How . Looked at our system and functionality– Other systems available to capture data– How can we have the data available to us?Other states were developing a program for leak inspection and other functionsA way to tie risers into an existing function–Service orders–Leak inspection–Inside inspectionsColumbia Gas of Pennsylvania ColumbiaGasPA.com 4
Who Who visits our meter sets on a consistent basis?–Service techs–Leak Inspectors–ContractorsWho has the knowledge or training to identify the risers?–Service techs–Leak Inspectors–ContractorsColumbia Gas of Pennsylvania ColumbiaGasPA.com 5
Timeframe Leak Inspection on CSLs are done on a 3 year cycle 2015 through 2017–By the end of 2017, every Riser will have been identified–Leak Inspectors identified each Riser while completing the CSL inspection–Pictures were taken of each RiserColumbia Gas of Pennsylvania ColumbiaGasPA.com 6
Remediation Company Owned Service Lines– Established a program to replace the identified Field Assembled Risers, as appropriate.Customer Owned Service Lines–Data is being gathered to establish a plan for replacement of Field Assembled Risers, asappropriate.–Some Service Lines are being replaced as part of Columbia’s accelerated main replacementprogram, per PUC approval in Docket No. 00072337.Columbia Gas of Pennsylvania ColumbiaGasPA.com 7
Training Booklets made to show examples of each riser–Distributed to Company personnel and Contractors–Discussed some minor differences to look for in some Riser typesColumbia Gas of Pennsylvania ColumbiaGasPA.com 8

The Benefits Pictures can be pulled for eachmeter to look at without a fieldvisit.A tech can pull a picture upfrom a previous survey for hardto find meters or properties. Farm taps may be easier to findfrom previous survey data. Knowledge of our system andareas for improvement. Data to be discussed in ourDIMP meetingsGPS coordinates can besnapped while onsite at themeter to help find meters in thefuture.Columbia Gas of Pennsylvania ColumbiaGasPA.com 19

connected drilling riser. A typical drilling riser stack-up is shown in Figure 1. Waves cause vessel surge and sway motions which are then transferred to the top of the drilling riser. Additionally, there is direct hydrodynamic load on the riser from the waves. Vortex-induced vibration (VIV) is another source of riser motions.
Riser must be separated from the casting upon completion so the connection area must be as small as possible Figure 11-13 Schematic of a sand casting mold, showing a) an open-type top riser and b) a blind-type side riser. The side riser is a
