EN Engineering offers extensive expertise and experience with gas
transmission pipeline engineering. Our team of professionals have been
designing, upgrading, maintaining, and operating gas transmission systems
for decades, and our pipeline experience ranges from large market,
expansion-driven, long haul projects, to maintenance-focused integrity
projects. Our experts provide engineering support throughout the various
phases of a project, including construction support and as-built activities
for transmission piping and associated facilities such as regulating
stations, metering facilities, and inspection facilities. EN Engineering is
also experienced in the requirements of FERC 7c filings.
Our team produces front-end engineering studies that further refine the
project scope, thus providing clients with a fatal flaw analysis that
identifies high-risk components and provides a proper schedule and capital
estimate for large projects. At the on-set of projects, clients rely on our
abilities to perform preliminary feasibility studies, budgetary analysis for
projects, and assistance in the up-front economic analysis of a project. We
work closely with operators to cost business opportunities, run hydraulic
models, and present supply options to stakeholders.
EN Engineering’s comprehensive services include the following:
EN Engineering provides proper coordination of any right-of-way,
geotechnical, and environmental surveyors needed for proper engineering.
From this information we finalize route selection; identify needed working
easements; establish pipe lay down yards, construction staging, and set up
areas; and provide route pipeline corridor access. This careful planning
also allows us to provide stormwater control features such as diversion
swales, sediment control barriers, and bladders.
When it comes to environmentally sensitive areas such as wetlands, stream
crossings, national forests, and other protected resources, EN Engineering
takes care to evaluate and recommend the proper, most cost-effective method
to installing pipelines. Our experts are very familiar with FERC-mandated
construction requirements and installation methods such as use of water
bladders, open cut, conventional bore, and HDD.
EN Engineering provides profiles, elevation details, and material take-offs
for valve settings and launcher/ receiver trap designs. Lines are reviewed
for HCAs and evaluated for internal inspection capabilities. Our
construction package provides detailed HDD analysis and incorporates
geotechnical data to develop a comprehensive profile along with proper
set-back areas.
Our engineering professionals perform complete layout and design services
for the successful construction of large pipeline crossings such as rivers
or other obstacles. EN Engineering combines geotechnical information, offset
requirements, and material selection into a recommended bore strategy. We
incorporate this engineering solution into an accurate and complete HDD
design package.
Safety is always at the forefront of any design. We have the expertise to
incorporate remote-operated and automated shut-off valves into your pipeline
design.
EN Engineering takes the unique characteristics of each installation and
incorporates them into the most effective CP design. As part of the
evaluation, we consider potential interference, shared right-of-way issues,
overhead AC systems, DC transit systems, electrical isolation, and soil
resistivity. Our team has the required expertise to review, identify, and
mitigate potential CP issues along proposed pipeline corridors as well as
expertise in the design and installation of rectifier systems.
Each and every design includes the proper material and equipment for clients
to complete the necessary inspections required by code. Our design includes
launcher/receiver traps and other required fittings so that Internal Line
Inspections (ILI) can easily be completed without interruption.
EN Engineering develops construction scope-ofwork documents and provides bid
support, including responses to requests for information from contractors.
Project management and construction support includes inspection supervision
and pipeline inspection services, development, processing, and review of
as-built drawings.
