EPC Contractor: Engineering Through Installation
One company designs it,
builds it and sets it
State Service Company delivers engineering, procurement, construction and installation under one contract from a 70-acre waterfront yard in Ingleside, Texas.
Design, fabrication and load-out happen at the same facility, so the party that engineers the module is the party that builds it and ships it. Single-source since 1976.
Engineering
Structural and facility design, detailed fabrication drawings, process, mechanical, electrical and instrumentation design, 3D modeling and ASME code documentation.
Procurement
Material sourcing, equipment procurement and expediting, with material test reports and full traceability from receipt through Smart Steel.
Construction
Fabrication, coating, testing and load-out at the Ingleside yard, including hydrotest, NDT and factory acceptance testing before anything ships.
Installation
Field set, tie-in, hook-up and commissioning support, offshore installation, daily progress reporting and startup assistance.
Why Split Scope Fails at the Seams
Split scope
- The engineer hands drawings to a fabricator who did not sit in the design reviews.
- The fabricator hands steel to an installer who was not there for the fit-up.
- Every interface becomes a place where responsibility is arguable.
One contract
State Service holds the whole scope. Engineering, procurement, fabrication and installation are performed by one company at one facility.
Decision speed follows from ownership. Privately owned, 50 years in operation and answering to no outside board, so scope changes and schedule calls get made quickly rather than escalated.
"Do whatever it takes to get the job done, wherever it might take us."

What Single-Source Delivery Changes On Site
1,300
People in the yard, none on your site
A facility of comparable scope built conventionally carries six to eight thousand people on site. State Service performs the fabrication scope with roughly 1,300 people in Ingleside.
2
Critical paths running at once
Yard fabrication proceeds while site civil work and foundations are still underway, so two critical-path activities overlap rather than queue.

Markets served
LNG, offshore oil and gas, midstream and pipeline infrastructure, and petrochemical and industrial facilities. See modular fabrication.
Frequently Asked Questions
What is the difference between EPC and EPCI?
EPC covers engineering, procurement and construction. EPCI adds installation, meaning the contractor also sets and hooks up the work in the field or offshore. State Service delivers both, and takes fabrication-only scope where engineering is already complete.
Does State Service self-perform fabrication?
Yes. Fabrication happens at the company's own 70-acre yard in Ingleside rather than being subcontracted, which is what allows engineering and construction to sit under one roof.
Can State Service work from owner-furnished engineering?
Yes. Scope can start at fabrication where the design is complete, or at FEED where it is not.
How does load-out work?
Completed work loads out across 2,000 linear feet of load-bearing bulkhead directly onto a barge, with a 12-mile run to the Gulf of Mexico and no vertical restrictions.
