Power skid frames and prefab power module fabrication

A power skid brings equipment onto a common base for a defined project or equipment program. The fabricated share can include the base frame, equipment mounts, connection plates, enclosure panels and brackets. The electrical equipment, controls and system tests form separate parts of the completed package. The bill of materials should make those boundaries clear.

A prefabricated power module may include more than the skid structure. For quoting, identify the exact assembly level you want delivered. An empty frame, a frame with installed panels and a completed electrical module require different inputs. Use the drawing and scope list to identify the work rather than relying on the word module alone.

The responsible engineer should define the equipment weights, positions and load cases. Include the mounting footprint of each item and the connection to the base. State which features control alignment between equipment. Show the anchor pattern and the final support conditions. A frame review cannot rely only on the total assembled weight.

Transport and lifting requirements also need a design basis. Show approved lifting points, fork pockets or handling details where they apply. Include the shipping state of the module. A base shipped empty and a base shipped with equipment can face different loads. Do not assume that a convenient frame opening is an approved lifting point.

Break the fabrication package into its welded assemblies and separate sheet metal parts. Identify which plates must be machined and which surfaces locate the equipment. Show weld symbols, cutouts, stiffeners and any fit limits. If a bracket carries a purchased component, include that component interface drawing or its controlled mounting dimensions.

Give each assembly a part number and revision. Mark any field installed pieces and list the hardware that goes with them. When the buyer supplies equipment, define the receiving condition and the work expected before it is mounted. The quote should state whether equipment installation, wiring or testing is included, rather than leave those tasks implied.

Ask us about AWS D1.1 welder qualification if your design requires it. Current welder qualifications and the applicable procedure records need confirmation for the work. Welding capability is not the same as an accepted code qualification. The quote should identify the required records and any inspection before production is released.

Florida has robotic welding, mild steel tank welding and stainless TIG capability. Irving has MIG welding alongside laser cutting and forming. Those facts do not establish that both plants can build every structural skid. Rich must confirm the plant, process, size limits and available hours for the specific assembly. Heavy frames should not be assigned to a plant by location alone.

Specify the finish system, surface preparation, color and any masking. Identify ground points, threaded holes and mounting faces that must remain clear. Ask us about powder coat, which is not yet a confirmed finish route. If paint must be repaired after assembly, provide the allowed touch up method and the acceptance limits.

List the records needed at shipment. They may include material identification, dimensional results, weld inspection, finish checks and an assembly record. The exact package must be agreed. If electrical assembly is included, send the bill of materials, wiring documents and test procedure. The completed power system remains subject to the OEM and project approval requirements.

A power skid needs an approval path for its structural frame as well as its electrical equipment. The engineer must define the load cases, weld requirements, anchors and lifting provisions. State which records and inspections are required for the fabricated base. The equipment maker or designated technical authority must also define acceptance of the completed power module.

List the material and weld records required for the frame, together with any dimensional or coating reports. If the project requires AWS D1.1 welder qualification, ask us for confirmation before relying on that route. Powder coat is also unconfirmed. The accepted scope should show how each structural inspection is completed before the base receives equipment or leaves the plant.

Use the RFQ form to send your power skid frame requirement. Include the company, contact name, email, plant location, quantity and target date. Attach a PDF, DXF or STEP file up to 25 MB. A dimensioned PDF should identify the current revision and the features that control fit. Add the material grade, thickness, finish and any inspection or packing notes.

Give the required date for the fabricated base separately from the schedule for the completed power module. Identify equipment supplied by your team and any inspection hold points before it is mounted. Kevin Leonard handles accounts, while Rich Fitzgerald reviews production and sourcing. The quote must define the frame scope and its accepted schedule before a production slot is committed.
