The Right Combination of Personnel & Process

The project consists of a $4.5 billion blue hydrogen clean energy complex to be built in Louisiana and the world’s largest instance of carbon capture.  The complex will produce 750MMscfd of blue hydrogen in Ascension Parish that will be delivered through 700+miles of pipelines.  The clean energy system will tie into 25 existing production facilities providing customers more than 1.6 billion cubic feet of hydrogen per day making it one of the largest producing hydrogen systems in the world.  With a 95% CO2 capture rate, it will be compressed to 2,160 psig and transported safely by pipeline 35 miles east of the new clean energy complex to multiple inland sequestration sites located along a pipeline corridor.  The complex will generate more than ten million metric tons per year (MTPY) of carbon dioxide which will be permanently sequestered in geologic pore space secured from the State of Louisiana approximately one mile below ground.  The clean energy complex will also produce 2.8 million metric tons per year of blue hydrogen that will be transported around the world.  Injection facilities will be installed in shallow water (10ft).  Pipelines will be constructed in predominately swamp terrain (shallow water areas) and will have complex horizontal direction drills that will need to engineered.   

Keystone is providing engineering, design, hydraulic analysis, automation & controls, SCADA, project management, survey, procurement, permit support, project scheduling, project controls,  cathodic protection & AC mitigation, geotechnical investigations, environmental support, and right-of-way support for all pipelines (Hydrogen, CO2 Mainline, CO2Distribution Lines and Natural Gas), measurement and regulation facilities, CO2 injection facilities, and tie-in locations along the system.

Developed of design basis, modified Optimoor model to reflect new monopiles, developed of SACS model, modified PSI file for soils, developed load cases for model, SACS model runs to size monopile and develop breasting spring criteria, developed dock information and design book, Phase IV construction estimate, bid tender package, permit support and construction support. Designed to accommodate mooring large vessels and access between dolphins/docks including lighting and electrical details. Included multi-pile structure for multiple quick release hook loading attachments.

Keystone led efforts to mitigate findings from HAZOP reviews.  Keystone assisted at5 different locations and the review scope ranged from 10 to 90 items.  Keystone was able to mitigate 65% of these findings without facility modifications, using additional analysis tools and process modelling.  If modifications were necessary, Keystone worked to minimize the field scope for most to a coding change or addition of a monitoring point.  For larger multi-discipline items, Keystone handled the design effort and coordinated installation with existing turnaround planning efforts.

Keystone provided project management, engineering, design, and procurement support services for the detailed engineering design of three laterals as part of the larger pipeline system connecting Orla to Mont Beliveau. The client installed approximately 132 miles of 24” ANSI 600# pipeline to transport Y-Grade or Raw NGL mix from Orla, Texas to High Plains, Texas. Additionally, a 30-mile lateral receiving Y-Grade NGL from ARM and transporting to the Shin Oak pipeline. The scope of work included a Coriolis Meter, pig traps, and multiple MLV’s.

Keystone provided site development engineering for an EPC contract to develop 7 solar farm facilities in Texas. The site developments totaled 130+ acres of solar farm development producing 16MW of power to directly tie into the electrical utility distribution network.
