What shops here make and for whom
The work splits into two rhythms. Petrochemical fabrication is driven by capital projects and turnarounds, where a plant owner or EPC contractor issues specifications, drawings and inspection plans and expects full material traceability. Shipyards and their suppliers work to hull-by-hull production schedules, where a late casting or a missed outfitting package ripples through several vessels.
Many smaller shops straddle both, taking skid and piping work one month and marine components the next, which makes costing and capacity planning harder than in a repeat-part machine shop.
Quoting and estimating realities
Quotes here are rarely a unit price on a drawing. They are built from material takeoffs, welding hours by joint type, inspection and testing steps such as radiography or hydrotesting, coating, and crane and rigging time. Steel and alloy price swings between quote and purchase are a constant risk, so many estimators add validity windows and escalation clauses.
The recurring failure is that the estimate lives in a spreadsheet while actual hours land in the ERP, so nobody learns which job types are consistently under-bid. Linking estimate lines to job cost actuals is usually the single most valuable analytics project.
- Keep estimate line items in the same structure as job cost codes
- Record the reason when a job closes over or under budget
- Track purchased material price at quote date versus PO date

ERP and systems seen in these shops
Smaller fabricators and machine shops commonly run JobBOSS, E2 Shop System or Global Shop Solutions, with others on Epicor Kinetic, Infor SyteLine, NetSuite or SAP Business One as they grow. Larger yards and EPC contractors typically combine an enterprise ERP with separate project, document control and engineering systems.
The common pain is the gap between those systems: drawings and weld maps in one place, purchase orders and routings in another, certificates in a shared drive. That gap is where retrieval over documents and read-only ERP queries can save real time, for example finding which heat number went into which spool.
Compliance, data handling and where private AI fits
Shipyard and Navy or Coast Guard suppliers handle controlled unclassified information and need to demonstrate NIST SP 800-171 controls. Petrochemical customers also guard drawings and plant layouts. In both cases, sending drawings or ERP data to a public AI service is often a non-starter, which favors open-weight models run on the shop's own hardware.
Private AI helps most on search across certificates, procedures and past quotes, and on plain-language questions over ERP data. It does not replace a qualified welding engineer, an inspector, or the code-required review of a procedure, and it should stay read-only against the ERP unless a person approves a change.
Frequently asked questions
Who helps small Louisiana manufacturers with improvement projects?
The Louisiana Manufacturing Extension Partnership (LMEP), hosted at the University of Louisiana at Lafayette, is the state's NIST MEP affiliated center. It offers consulting and training for small and mid-sized manufacturers. Louisiana Economic Development also runs workforce and incentive programs such as FastStart and ITEP.
What certifications do Gulf Coast fabrication shops usually need?
It depends on the customer, but ASME stamps for pressure vessels, AWS D1.1 welding qualifications, ISO 9001 and API Q1 are common asks. Government shipbuilding adds Navy or Coast Guard technical requirements and cybersecurity obligations for controlled unclassified information.
Can AI read our drawings and certificates without leaving our network?
Yes, if the model runs on your own servers or in a private cloud you control. Open-weight models can index certificates, procedures and ERP records locally. Results should cite the source document so a person can verify a heat number or specification before acting on it.
Is a general ERP assistant enough for a fabrication job shop?
Sometimes. If your ERP vendor ships an assistant that covers your questions and your data policy allows it, use it. Private deployments make sense when you need to combine ERP data with documents, keep everything on site, or work with systems the vendor tool does not cover.
