Outline

1. What I learned in six months at PG&E

2. Challenges

3. Areas to improve & proposed methods

4. What’s next? Going upstream & understanding integrity

management

5. Goals for my next rotation

Pipeline Engineering & Design Group – March 6, 2015

Shorts assigned to be IFC’d by January 2015 = 20

Shorts IFC’d by January 2015 = 2

Shorts IFC’d to date = 3

Total # shorts contribution = 5

Challenges with emphasized goals


Analogous to GT PED STIP = 0.0

L-105A valve replacement in Oakland


Limited funds &

restricted compliance

date prevents

compiling project with

neighboring work

12 kV electric line

creates limited space

to install 30” TDW on L-

105A

12 kV electric line

105A

Undefined station and

transmission pipe

boundary

Station Feature List

(SFL) unavailable to

verify scope

Historical design flaw:

Liquids risk at low point

within 100’ of station

features

Challenges: L-121 in Yuba City


Low point

Undefined station and

transmission pipe

boundary

Station Feature List

(SFL) unavailable to

verify scope

Historical design flaw:

Liquids risk at low point

within 100’ of station

features

Excavation damage

risk: Line 167 within 2’

of existing L-121 (VIF)

7

Challenges: L-121 in Yuba City


8

L-132 pipe replacement in SF


Replace 2.7’ IM flagged D

pipe

ANSI 300 upgrade of pipe

assembly – should be

sufficient pressure bounds

contradictory dimensions on

As-builts

Overall recommendation to

reduce short pipe

replacements by expanding

future hydrotests

STAGE 1

IM sifts through PFL and prioritizes

flagged segments

STAGE 2

Engineering validates data &

scope and determine plan

of action

STAGE 3

Project management assigns job #s,

order #s, & stakeholders

STAGE 4

Engineering & Estimating 60/90/IFC

drawing review process

STAGE 6

PM, Construction & Engineering

complete construction

Goals for Integrity Management

PED project forecast

Address IM

flagged pipe

Public & Employee

Safety, Engaged

Employees

Improve scopes for

pipeline projects

Understand how pipe

segments are flagged

given available records

Learn to discern what

projects to prioritize

based on IM industry

studies

Explore the

methodologies to

mitigate risk and refine

where necessary

Nick Jordan for his support with the L-105A Oakland project,

valuable feedback & insight, and field exposure

Shiela Moore for document research recommendations

George Farage for thorough review of PDS documents upon

projects assignments, helpful suggestions on project workflow

efficiency and overall investment in my professional growth

Ed Stracke for grilling me with questions

Neil Flemmer for supporting shorts projects, feedback on design’s impact on construction

Francisco Castro for the opportunity to learn & contribute to the

PED group
