Background

The client wanted to eliminate all submersible transformers on their distribution system to allow improved access to equipment and replace aged equipment. A total of 500 underground facilities were to be converted to above ground pad-mounts. EN Engineering replaced all primary and secondary cables, along with the terminal poles associated with these locations.

Challenges

This program took place in upscale, older neighborhoods that were unaccustomed to seeing traditional pad-mount transformers. It was critical to educate customers on the improvement in reliability associated with the new transformers and to work closely with the customer and county to select transformer locations that would minimize visual intrusion while maintaining the electrical improvements desired. In addition, the project provided the opportunity to evaluate and identify looping and reliability opportunities for these neighborhoods.

Solutions

EN Engineering independently ran this new program and provided critical client communication. The team was responsible for planning, detailed design, cost estimating, permit package preparation, easement research, acquisition identification and construction support. More than 250 transformers and 25 miles worth of cabling were targeted for replacement over the course of a three-year construction cycle. The primary, secondary and associated service cabling was also replaced and additional looping was targeted. Our designers were responsible for doing the scoping, detailed design and construction support for all sites associated with these replacements.

It was critical to educate customers on the improvement in reliability and safety associated with the new transformers.

Challenges

EN Engineering had to quickly assemble a team of 40 professionals to execute a high-volume project within an aggressive schedule of a five-month period that required more than 200 detailed designs and over 600 cost estimates.

Solutions

EN Engineering completed detailed designs and cost estimates associated with the client’s Energy Grid Modernization Filing with the IURC. The team completed preliminary engineering, field data collection, detailed design, project management, and complete project controls for all distribution jobs associated with the filing. The detailed design included drawings, permit packages, cost estimates, pole loading analyses, work order creation, and ESRI GIS updating. Over five months, 200 detailed design projects and 600 cost estimates were completed. The filing helped the client secure $500,000,000 in funding for grid modernization projects over the next five years. This success was due to EN Engineering’s critical focus on training and understanding of the client’s internal systems and standards.

Over five months, 200 detailed design projects and 600 cost estimates were completed.

Challenges 

The client had two, 20-year-old flare stacks with internal corrosion from the process environment, and the stacks had begun to lean. A temporary solution was needed to enable continued operation until the flare stacks could be replaced. The client also requested a full-service solution for the design and off-site fabrication of flare stacks for two vessels. In addition, the client requested a plan for demolition and installation of the new stacks and on-site supervision of the project.

Solutions

EN Engineering provided detailed design for temporary support for the existing stacks, allowing them to remain in operation until new stacks could be designed, constructed, and installed. EN Engineering also prepared a detailed engineering design package for the installation of the two replacement flare stacks. As a benefit to the client, the new stacks were redesigned with silencers, which were relocated to the roof to grant easier maintenance access. New platforms were designed to aid in access to flow control and flare equipment. The EN Engineering team provided 24/7 staffing to supervise both demolition and installation. The stack replacement was completed on schedule and under budget with no safety incidents.

“The engineering was under budget and on schedule. The quality was excellent. Everything fit just right, and there was no rework.” – Client Project Manager

Background

Our client, one of the country’s largest refineries, requested that EN Engineering perform a Process Safety Information audit for their FCC unit.

[/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

This audit had to comply with the requirements of the Refinery PSI Standard Practices. The request for proposal identified the following elements which were audited during this process:

  • Plot plan drawings
  • Process flow diagrams
  • Electrical area classifications
  • Equipment files/Instrument data sheets
  • Equipment files/Relief valve data sheets
  • Equipment files/Fixed and rotating equipment
  • Material and energy balances
  • Ventilation system design data
  • Occupied buildings ventilation system design data
  • Pressurized/purged enclosures

Solutions

EN Engineering assembled an expert team of PSI professionals. The team consisted of an audit leader, two P&ID walk-down staff, one Electrical & Instrumentation engineer, and one staff member reviewing M&E balance information.

The objective of the audit was to identify compliance status with the selected PSI elements and to provide focused guidance to upgrade the level of compliance of the Process Safety Information program. These PSI audits are in alignment with the facility PHA standard that requires PSI to be evaluated and updated prior to submitting PSI records to the PHA team in advance of the actual PHA start date.

The EN Engineering team is a critical part of our PSI Program. Their experience and expertise support our PSI efforts, and they provide high-quality work for the refinery.

Background

Our client, a large gas energy holding company, enlisted the services of EN Engineering to undertake a long-term, large-scale main replacement program in its Ohio service territory in order to improve the reliability, efficiency, and safety of their gas distribution system.

[/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 long-term project included field noting to build a base map of existing conditions, and the creation of construction drawings that illustrated tie-ins and line of lay for the new gas mains.  Many of the replacements were in congested urban areas with a large number of existing utilities, which created design challenges.

Solutions

As part of an Accelerated Main Replacement Program (AMRP), the client replaced nearly 1,200 miles of 12-inch and smaller cast iron/bare steel gas main over 15 years. EN Engineering worked on the AMRP from 2007 through 2015, successfully completing the design and permitting for more than 400 miles within the aggressive schedule.

Each year throughout the project, the client requested that EN Engineering design additional footage based on the valuable experience, dependability, and the high quality work product provided. In addition, due to new efficiencies created by the team, EN Engineering dropped its fixed fee prices each year.

Based on the success of this program, EN Engineering earned a multi-year contract to submit permit applications for the renewal of 60,000 services throughout the client’s Ohio and Kentucky service territories as part of their Accelerated Service Replacement Program (ASRP) over the next ten years.

Within an extremely aggressive time frame, EN Engineering successfully completed the design and permitting of more than 400 miles of main replacement.
