Recognizing Otis’ unique capabilities in dealing with tough logistical circumstances, Sunoco chose Otis to construct the very complex, highly challenging Spread 6 of its Mariner East II Pipeline. Governmental agencies from the federal level, State of Pennsylvania, and numerous counties and towns all trust Otis’ compliance expertise. Completing this high-impact project on time with minimal disruption to the property and lifestyle of roughly five million people within the construction zone required the intricate, in-depth scheduling and logistical planning of Otis. Characteristics of this 34-mile rural, suburban, and urban project are as follows:
Three Different Pipeline Diameters
- 12”
- 16”
- 20”
Three Different Methods of New Construction
- Open Ditch
- HDD – Horizontal Directional Drill
- Boring
Northwestern PA
Based on its long-standing relationship with Otis, National Fuel Gas tapped Otis to enhance its system to carry more Marcellus Shale gas to consumers. In addition to dealing with congestion surrounding drilling operations, Otis faced and overcame tough environmental challenges. Spread over multiple years, Otis constructed more than 20 miles of gathering and transmission lines. Upon completion, Otis restored the right-of-way to the acceptance level of both landowners and National Fuel Gas. The circumstances and environment for this project are best described as:
- Pennsylvania State Forest Land
- Rugged Terrain
- Mountainous Steep Slopes
- Side Slopes
- Extensive Stream Crossings
PSEG Keys Energy Center
Providing transmission facilities for natural gas to this 755-MW power plant in Prince George’s County, MD required services and expertise far beyond those of a typical pipeline constructor. Otis utilized its experience and expertise to perform the necessary functions to take this supply requirement from concept to reality. Services provided by Otis included:
- Right-of-Way Acquisition
- Engineering
- Materials Acquisition
- Pipeline Construction
- Testing
- Turnover
This project was completed on time and within budget, enabling this $850 million project to become a productive state-of-the-art clean energy provider of electricity in the Eastern United States.
