Oil & Gas Skid Package Engineering: Scope & Deliverables | KHAAS
A clear engineering scope helps an oil and gas skid package move from enquiry to fabrication with fewer unresolved interfaces. The owner, EPC contractor, equipment vendor and fabricator need to know which inputs are required, who approves them and what the engineering package will contain.
KHAAS Design & Engineering supports skid package engineering through structural analysis, layout coordination and detailed documentation. This guide outlines the inputs, deliverables and review stages to define before work begins.
Define the package boundary and responsibilities
Identify battery-limit piping connections, utility interfaces, equipment supply, structural supports, anchorage and the installation boundary. A responsibility matrix should separate process design, equipment selection, instrumentation, electrical design, structural engineering and fabrication.
Engineering services do not automatically include equipment procurement, manufacturing, testing or commissioning. Record these responsibilities explicitly in the agreed scope.
Engineering inputs for an oil and gas package
P&IDs, equipment list, data sheets and piping specifications.
Vendor drawings, operating and test weights, centers of gravity and support loads.
Site location, environmental loads and applicable project specifications.
Package footprint, tie-in coordinates and maintenance requirements.
Lifting philosophy, shipping envelope and transport restraints.
Required calculations, drawing formats, review stages and schedule.
Track missing information with assumptions and hold points rather than allowing it to disappear into the design.
Design methodology and review stages
Scope review: agree boundaries, design criteria and the deliverables register.
Layout development: coordinate equipment, piping, supports and access.
Analysis: assess the applicable structural and handling load cases.
Detailed design: complete connection, support and interface details.
Review and issue: resolve comments and release the agreed document status.
Fabrication support: assess technical queries and controlled design changes within scope.
Typical oil and gas skid package types
The workflow applies to pump, filtration, metering, utility and process packages. Specialized requirements depend on the equipment and service.

What should the engineering deliverables include?
The agreed deliverables may include the design basis, general arrangement, 3D coordination model, calculation reports, structural fabrication drawings, lifting details, material take-off and foundation reactions.
Each document should have a clear revision and issue purpose. Drawings must reflect the equipment data and assumptions used in the corresponding analysis.
Managing interfaces and design changes
Changes to equipment weight, nozzle position, piping reactions, footprint or shipping method can affect several disciplines. Review their consequences before approving the revised configuration.
Maintain an interface register for open vendor data, client comments and fabrication queries. Coordinate final reactions with the foundation design team and piping support requirements with the stress engineer.
Skid package engineering FAQs
What makes a quotation accurate?
A defined package boundary, reasonably mature vendor data, a deliverables list and an agreed review cycle allow the engineering effort to be assessed more clearly.
Does an engineering drawing confirm the package is ready to operate?
No. Fabrication, inspection, testing, installation and commissioning remain separate activities with their own responsible parties and acceptance requirements.
Can an existing package be modified?
Yes, subject to reviewing its as-built condition, original design information and the proposed loads and interfaces.
