Relocating a used gas turbine requires a defined equipment boundary, documented condition, an engineered transport plan and a receiving site ready for installation. Compare offers through commissioning and acceptance. Before purchase, establish who supplies missing components, preserves the equipment, resolves site differences and demonstrates performance after the move.
The advertised turbine may be available immediately while essential work at the destination remains unresolved. The buyer needs to know what is available, what can leave the seller's site, and what must be rebuilt or added at the destination. Each question changes the acquisition decision.
Use the gas turbine equipment hub to identify candidates, then develop a relocation scope for each serious offer. A useful comparison follows the equipment from its present condition to an agreed operating outcome. It also shows where responsibility passes between the seller, transport contractor, installer and commissioning team.
Key Takeaways
- Define the complete equipment and documentation included before committing to removal or transport.
- Verify shipping dimensions, mass and lift arrangements against the actual transport configuration.
- Preserve condition evidence and component identity through every handover.
- Resolve fuel, electrical, environmental and civil interfaces at the receiving site before dispatch.
- Agree commissioning responsibilities, acceptance criteria and the treatment of missing equipment in the purchase scope.
Define the equipment boundary before discussing the move#
Start with a tagged inventory and a marked drawing showing what transfers. A generating package can include the turbine, generator and selected auxiliaries while relying on site-owned systems for fuel treatment, cooling, control power or electrical export. Describing a sale as a complete plant does not settle those boundaries.
Ask the seller to identify excluded equipment explicitly. A component still visible in a site photograph may belong to another operating unit, be retained by the owner or be removed under a separate contract. Match photographs to the inventory so the engineering team can identify what it is actually designing around.
Equipment and information to reconcile before purchase#
| Scope area | Evidence to request | Consequence of an omission |
|---|---|---|
| Main generating train | Unit identities, configuration, couplings and installed upgrades | Unclear adaptation or reassembly scope |
| Auxiliary systems | Tagged fuel, lubrication, cooling, ventilation and starting equipment | Replacement equipment and new interfaces |
| Electrical equipment | Generator data, switchgear, transformers, protection and control power | Redesign of the site connection |
| Exhaust and emissions systems | Physical scope, condition and applicable technical records | Missing equipment or incompatible operating assumptions |
| Controls and documentation | Drawings, software backups, access rights, settings records and manuals | Commissioning delays or unsupported controls |
| Tools and spares | Identified special tooling, consumables and serviceable spare parts | Additional procurement and outage exposure |
Check the commercial right to transfer the equipment and the rights needed to operate and support its software. Treat these as distinct deliverables. A seller's possession of a control cabinet does not answer whether the buyer can obtain the access, documentation and service support required at the new site.
Agree how discrepancies are resolved before dismantling begins. Once cables, piping and equipment have been separated, reconstructing the original scope becomes more difficult. The power procurement roadmap provides a wider project sequence; the relocation inventory should become a controlled input to that sequence.
Establish condition before the equipment changes hands#
Separate the turbine's maintenance history from the condition of the complete package today. Review operating records, inspections, repairs and preservation records together. A unit with little recorded operation can still require work because of storage conditions, incomplete preservation or deterioration of supporting equipment.
Where access permits, collect the relevant condition evidence before removal. Agree inspections with the responsible technical specialist and record the inspection limits. If an operating test is unavailable, state which performance assumptions remain untested and how the buyer will address them through inspection, refurbishment or acceptance terms.
GE's Maxim Power relocation case study describes a third-party 7F.05 acquisition that involved stored equipment, relocation and a combustion-system upgrade for local gas characteristics. It is an OEM-reported project example. It illustrates why a move may include technical adaptation; it establishes no standard storage allowance, relocation cost or delivery schedule.
Record serial identities privately and maintain a photographic condition record at agreed milestones. Include loose parts and disconnected instruments. A component can arrive undamaged yet remain unusable if its mating part, calibration record or position in the original system cannot be identified.
The GE 7F dossier can help frame model-family questions. For a purchase decision, the evidence must follow the individual offered turbine, its actual generator and its installed systems. Use the same identity references in the inspection report, packing list and acceptance record.
Review the used-turbine remaining-life and overhaul assessment alongside the relocation scope to distinguish equipment condition from the work required to move it.
Measure the transport configuration#
Published dimensions can identify an early transport challenge. They cannot replace the shipping drawing for the actual load. Determine which items travel together, which are removed, how the equipment is supported, and how packaging changes the envelope and mass presented to the transporter.
The following reference dimensions come from Solar Turbines' PGM60 datasheet. They apply to the stated compact-filter package configuration and dry-weight basis. They are physical package data, not a shipping plan or an electrical-duty comparison. Solar PGM60 datasheet, DSPGM60/0624/EO.
Solar PGM60 reference dimensions: Taurus 60 package#
| Published physical field | OEM reference value | Transport clarification still needed |
|---|---|---|
| Length | 12.4 m | Actual length after approved disassembly and packing |
| Width | 2.5 m | Projections, protection and restraint envelope |
| Turbine enclosure height | 3.4 m | Transport support and trailer contribution to overall height |
| Minimum height with filter | 7.6 m | Filter removal and separate shipping arrangement |
| Approximate dry package mass | 51,500 kg | Verified transported mass, lifting accessories and packing |
51,500 kg — Solar's approximate dry PGM60 package mass is a reference for early screening; the transporter still needs the actual load configuration.
The difference between enclosure height and height with the filter shows why a single height copied from a brochure can mislead. Neither value establishes overall road-transport height. Have the transport engineer assess the full arrangement, including support equipment, clearance and access at both sites.
Request the center of gravity, approved lifting points, transport restraints and limitations from the responsible equipment specialist. The lifting contractor should develop the lift plan from verified loads and site conditions. Capacity stated for a crane without its operating geometry is incomplete information for planning the move.
Review the entire route, including any port leg and the last turn into the receiving site. Include unloading space, temporary storage, ground conditions and access for later maintenance. The Taurus 60 dossier identifies the family; the offered package configuration determines these physical requirements.
Keep preservation and custody continuous#
Create a preservation plan that covers disconnection, packing, transport, storage, unpacking and reassembly. Ask the OEM or responsible service provider for the applicable procedures. Define who performs each task and which records travel with the equipment. Avoid assigning a generic preservation method to every turbine and generator.
The plan should address exposed openings, moisture control, contamination prevention, component support and any inspection or monitoring required during storage. Specify the conditions that trigger reassessment after a delay or transport incident. Give the receiving team the event history and receipt inspection so it can assess the equipment's release condition.
Records to retain at each custody transfer#
| Handover | Minimum project record | Receiving party's decision |
|---|---|---|
| Seller to removal team | Baseline condition, inventory and isolation boundary | Whether removal can begin within the agreed scope |
| Removal team to transporter | Packing list, protection record and transport configuration | Whether the load matches the transport plan |
| Transporter to storage or site team | Receipt inspection and recorded transport exceptions | Whether further inspection or preservation is needed |
| Storage team to installer | Preservation history and release condition | Whether equipment can proceed to installation |
| Installer to commissioning team | Reassembly records, completed checks and open items | Whether systems are ready for the next test stage |
Plan for delay before it occurs. If foundations are late, identify a suitable holding location and the party responsible for preservation there. Include access for inspections and the resources needed to maintain the agreed conditions. A parked shipment can create a new storage obligation that neither original contractor priced.
Record who authorizes corrective work if the receipt inspection finds damage, missing parts or a preservation lapse. Agree the notification deadline, evidence required and process for revising cost and schedule. A custody signature should identify received items and observed condition without being treated as proof of mechanical performance.
Keep high-resolution nameplates, location details and sensitive drawings within the project information process. Public marketing photographs serve a different purpose from the technical record required to preserve component identity. The buying team needs both an accurate private record and control over where that record is distributed.
Resolve the receiving site's interfaces#
Confirm that the destination can support the offered configuration. Review fuel composition and delivery, electrical compatibility, ambient conditions, cooling, inlet and exhaust arrangements, noise and the approvals needed for the proposed use. The previous installation is evidence of a previous application; the new site needs its own engineering basis.
Package descriptions deserve particular attention. Siemens Energy offers different SGT-800 package arrangements, including configurations in which the generator is separate from the driver unit. Establish which arrangement is being sold before assigning foundation, transport or installation scope. The SGT-800 dossier supports the initial equipment comparison.
Solar describes its Power Generation Modules as factory-preassembled equipment with defined interfaces and a non-hazardous-application limitation. That qualification belongs in the site review. An OEM's modular product description does not certify an offered used installation for every receiving environment.
Receiving-site questions that change the relocation scope#
| Interface | Question to close before dispatch |
|---|---|
| Civil and structural | Are foundations, anchors, loads and maintenance clearances designed for the actual package? |
| Fuel | Can the site deliver approved fuel conditions throughout the intended operating range? |
| Electrical | Do frequency, voltage, grounding, protection and connection arrangements fit the proposed operating mode? |
| Mechanical services | Are cooling, ventilation, drains and other required services available at the agreed boundaries? |
| Inlet and exhaust | Are losses, layout, supports and emissions-system interfaces within the approved design? |
| Operational readiness | Are staffing, spares, procedures, tools and technical support ready for commissioning? |
Identify temporary services as well as permanent ones. Installation and commissioning may need power, fuel, water, lifting access or test equipment before the normal plant systems are available. Put those requirements into the schedule and assign them to a named work package.
For a data-center project, keep IT capacity and facility power delivery on a consistent basis when setting the acceptance duty. The data-center generator procurement overview supplies broader context. This relocation enquiry should identify the specific electrical delivery point and loads the accepted plant must support.
Use the gas turbine frequency-compatibility assessment to develop the electrical adaptation enquiry for the offered generating package.
Compare schedules and costs through acceptance#
Ask every bidder to show the same milestones: access for inspection, release for removal, packing, dispatch, receipt, mechanical completion, first firing, performance testing and acceptance. Each milestone should have an entry condition and a responsible party. A date unsupported by those dependencies is difficult to compare with another offer.
Build the schedule around the actual sequence. Transport can proceed while some site work continues, but only if storage and later installation remain practical. Overlap is a project choice with dependencies and costs; it should not be assumed merely because equipment is available for collection.
Use a complete cost schedule with explicit inclusions. Compare acquisition, removal, transport, insurance, storage, refurbishment, missing equipment, site adaptation, installation and commissioning. Record quotation date, currency, exclusions and the validity period of each estimate. The sum is useful only when the items share a consistent scope.
Make uncertainty visible by work package. An unknown generator condition calls for a different response from an unconfirmed transport route or an incomplete gas connection. Resolve the largest decision-changing uncertainty before adding precision to smaller estimates. A single contingency percentage cannot explain which unresolved issue could prevent operation.
Where temporary generation is proposed, compare its actual delivery and operating scope against the relocation schedule. The backup-power procurement discussion addresses another equipment pathway. Temporary generation, grid supply, gas engines, fuel cells or solar with storage each need a defined duty and feasible site arrangement before entering the comparison.
Specify what commissioning must demonstrate#
Commissioning should follow an agreed plan prepared by the responsible technical team. Define the systems to be checked, the prerequisites for testing, the parties attending and the records required. Keep mechanical completion, successful startup and contractual performance acceptance as distinct milestones with their own evidence.
Solar's field-services description includes startup, commissioning and electrical, mechanical and controls support. That is a service offering, not a reservation of personnel for a specific purchase. Obtain confirmation of the actual scope, mobilization assumptions and support availability when developing the relocation schedule.
For open-cycle gas-turbine thermal performance, ASME's public PTC 22 description identifies testing of corrected power, heat rate and exhaust conditions. Match the agreed method to the equipment and measurement boundary. Protection, load acceptance, emissions and reliability need their own acceptance evidence.
Specify which open items prevent acceptance and which can be closed afterward under an agreed process. Keep drawings, settings backups, training and preservation records in the final handover scope. Otherwise, a plant may produce power while the owner remains unable to maintain or support it effectively.
Acceptance evidence to assign in the purchase scope#
| Milestone | Evidence to agree before purchase |
|---|---|
| Receipt | Reconciled packing list, condition photographs and recorded exceptions |
| Mechanical completion | Reassembly records, completed system checks and identified open work |
| First operation | Approved commissioning records for the installed configuration |
| Performance acceptance | Results against agreed duty, boundaries, corrections and tolerances |
| Owner handover | Final drawings, software access, training and responsibility for remaining items |
Use these milestones in the payment and handover discussions. Define what happens if first operation succeeds but an agreed performance criterion remains unmet, including corrective work and retesting. That distinction gives the buyer a usable acceptance process before the equipment leaves the seller's site.

FAQ: relocating a used gas turbine#
Can any used gas turbine be relocated?#
Relocation feasibility depends on condition, equipment completeness, the transport arrangement and the receiving site's requirements. The assessment may identify required refurbishment or adaptation that changes the purchase decision. Obtain a configuration-specific engineering and scope review before treating a model's previous operation as evidence that it fits another site.
Does modular packaging establish a short relocation schedule?#
It can simplify some transport and installation interfaces. The actual schedule still depends on removal, condition, site readiness, missing equipment and commissioning support. Confirm the offered package arrangement and the work included in the quotation. Factory assembly claims for new equipment do not establish the schedule for a used installation.
Can brochure weight be used to book the transporter?#
Use it for initial screening. The transporter needs verified dimensions and mass for the actual shipment, including approved disassembly, supports and packing. Separate installed height from shipping height. The route and lifting plans also need load distribution, access and the receiving site's unloading arrangement.
What if the turbine cannot run before purchase?#
Identify which condition and performance questions remain unanswered. Agree available inspections with a qualified specialist, then define how refurbishment, testing and acceptance address the remaining uncertainty. A documented limitation allows the buyer to compare the offer honestly; an assumed successful run does not provide evidence.
Who should preserve the equipment during a delay?#
Assign that responsibility in advance for each location and custody period. The preservation plan should specify applicable procedures, inspection records and the response to changes in storage conditions. If dispatch precedes site readiness, include the holding location and preservation resources in the cost and schedule.
What belongs in the final relocation handover?#
Include the reconciled inventory, condition and preservation records, reassembly documentation, test results, drawings, controls backups and remaining open items. Confirm that the owner has the access, training, tools and support needed to operate the equipment. Acceptance should follow the agreed project criteria and documented responsibilities.
