Challenges

As a new company, the client had not yet developed comprehensive project procedures, so one challenge involved working together to establish new processes and standards. In addition, the project had an aggressive timeline and required the team to work at an accelerated pace.

Solutions

EN Engineering provided project management, engineering, and design services for a new pipeline system consisting of more than 70 miles of 8” and 12” diameter pipeline, as well as five new injection facilities for multiple third-party producers.

Experts from EN Engineering’s entire service portfolio came together to successfully complete the project. The pipeline design team provided oversite of the pipeline routing as well as development of engineering design details, while a facility team provided full mechanical, electrical, civil, and structural design packages, along with hydraulic and surge analysis.

Environmental experts oversaw an environmental survey and provided recommendations for both compliance measures and installation best practices along the pipeline. Several scenarios for flow modeling were evaluated by the integrity team, who also provided recommendations for emergency flow restricting device (EFRD) valves. GIS services were utilized to evaluate alternate pipeline routes and make a commercial recommendation. Designs for cathodic protection were provided by the corrosion team. Finally, procurement experts provided comprehensive support on all equipment, material, and labor contracts, from specification development to expediting and tracking deliveries.

EN Engineering also provided several specialty services, including in-house HAZOP facilitation and shop inspection services, and managed geotechnical, environmental survey, and mill inspection subcontractors. The automation team developed the control philosophy for the injection facilities and interfaced with third-party programmers and PLC integrators.

The EN Engineering team was instrumental in guiding industry best practices and helping the client develop new procedures and standardizations. In addition, they facilitated communications despite several changes in client stakeholders at critical stages during front-end loading and worked at an accelerated pace to meet project deadlines.

Background

Our client, the owner and operator of the gas and electric infrastructure in the Baltimore metropolitan area, called on EN Engineering to assist with a large electric distribution upgrade project and provide design services for storm hardening with the assistance of Smart Grid technology.

[/fusion_text][/fusion_builder_column][fusion_builder_column type=”2_3″ layout=”2_3″ spacing=”” center_content=”no” hover_type=”none” link=”” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding=”” dimension_margin=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_text]

Challenges

The proposed plan required overhead structures to be installed in a county park, which would have delayed the construction due to permit issues. In addition, a rare tree was rooted in the area, so a workaround had to be designed.

Solutions

EN Engineering provided design services for storm hardening to reduce supervisory control and data acquisition (SCADA) on outages, including the installation of Smart Grid technology to 40 poles of overhead electric cable and 5,090 linear feet of underground electric cable. This included an overhead recloser, fuse coordination, re-conductoring to Hendrix spacer cable, and pad-mounted equipment. The EN Engineering team prepared construction prints, communicated with the client’s project manager and engineer, conducted quality assurance/quality control reviews, and submitted all required permit application documents.

To resolve the issue of overhead structures in a county park, the team mitigated the potentially long lead time by making adjustments to the scope. The revised plan met the requirements of the client’s engineer and reused existing overhead structures to avoid work within the county park property. In addition, they avoided negative impact to a rare tree by using poles owned by a communication company.

The EN Engineering team provided technical support throughout the construction procurement process and communicated with the client’s customers and local government departments to keep all stakeholders apprised of the project’s progress. The project was completed in 2017 without any issues, on time, and on budget. Since then, seven additional projects of similar scope have been completed successfully. The client has demonstrated their confidence in the team’s communication, quality, timeliness, and ability to mitigate design and construction issues by rewarding EN Engineering with additional design projects.

Project

Corrosion Control for City of Houston Water and Wastewater Group

 

Location

Houston, Texas

Background

The city of Houston called on EN Engineering to assist with a corrosion control project for their Water and Wastewater Group. The project is the Corrosion team’s largest water project to date.

[/fusion_text][/fusion_builder_column][fusion_builder_column type=”2_3″ layout=”2_3″ spacing=”” center_content=”no” hover_type=”none” link=”” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding=”” dimension_margin=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_text]

Challenges

Houston is the fourth largest city in the country, so the initial challenge included locating the hundreds of corrosion control systems that needed to be assessed. Once located, the team documented locations to create a historical record of corrosion data for future reference and began the large-scale assessment process. The project continues with ongoing monitoring and maintenance.

Solutions

The scope of the five-year project includes maintenance of the current system, design of new systems, and analysis on lines that fail. The project involves all of the large diameter water mains, facilities, and wastewater systems throughout the city.

During the initial months, the EN Engineering team began locating and assessing the current corrosion control systems by identifying and visiting all the pipelines and facilities around the city. The team went out with metal detectors to find the caps that lead to the water lines. Once located, a GPS reading was taken and the information was entered into a GIS mapping database to make the process easier in the future. The team used a GIS mapping tool and added information on water lines and test stations to the city’s map to help determine where the lines are located and enable the team to assess CP levels by regions. The GIS tool also created a historical record of corrosion data for future reference.

Following completion of the identification and assessment of all the locations, the city requested that the EN Engineering team focus on stray current studies of the mainline water lines in the area of the Metro Light Rail system. In addition, they asked the team to help update the city’s GIS system and integrate all of the previously collected data, including test station readings, rectifier readings, water line leaks, soil resistivity and soil samples. Once all the information is compiled and processed, it will permanently reside within the city’s system.

The client’s vast corrosion control systems were successfully located, assessed, and documented in the city’s GIS system.
