Baker Hughes turbomachinery

Equipment families and the project scope

Baker Hughes brings gas and steam turbines, centrifugal and axial compressors, reciprocating compressors and expander solutions into its industrial equipment portfolio. A complete installation may contain several separately identified machines.

Start by specifying the process or drive task and the equipment that should be included in the proposed supply.

Separate a new machinery project, a complete replacement and maintenance components for an installed unit. Provide the plant equipment tag, driver and driven-machine arrangement, and an overall list of the installation.

This connects the technical requirement to a defined asset rather than only to a broad brand name.

Inputs for new machinery and replacement equipment

Submit the project data sheet with the service medium, operating conditions and required output or shaft duty. Retain units for every value and distinguish normal, minimum and maximum conditions where the project defines them.

Include driver requirements, installation layout and connection information appropriate to the particular machine.

A replacement project should show the current equipment and the new requirement separately. Provide the installed nameplate, relevant drawings and any changes in process duty. Identify retained interfaces, available space and auxiliary systems so the proposed scope addresses the actual installation.

Keep a controlled revision of the equipment list and mark amendments when the duty, arrangement or package scope changes. Photographs support the installation documents; they do not replace the dimensions or project requirements needed to define the interfaces.

Installed identity and component references

Provide a readable machine nameplate, serial number and complete type designation, including suffixes. Attach the applicable assembly drawing and parts list with the required item marked. A drawing position remains meaningful only when linked to its document and the particular installed machine.

Where an original reference is missing, supply the available operating records, previous confirmed specification and photographs of the marked component. Identify the source of dimensions and descriptions. Keep internal warehouse codes as additional references associated with the actual equipment.

Following modifications, use current documents and identify the changed assemblies. For multiple machines, group requirements by serial number and include attachment filenames in the procurement table. Preserve separate quantities for assemblies, individual components and maintenance sets.

Gas-turbine families and package configuration

NovaLT12 and NovaLT16 belong to the NovaLT family, while Frame and aeroderivative LM/LMS machines represent other portfolio groups. Retain the exact installed designation, including references such as Frame 5/2E, Frame 6/1B, LM6000PF+, LM9000 or LMS100PB+, where shown in the equipment records.

For a maintenance item, identify the particular turbine assembly and recorded part reference. Separately document package auxiliaries with their own nameplates and connection information.

For a complete assembly, show its boundaries and contents in the relevant drawing rather than relying on a general unit description.

For new equipment, provide the required drive or power-generation duty and package conditions from the project. A planned-maintenance list should distinguish essential replacement items from optional stores stock, with each line linked to the relevant machine and document revision.

Steam-turbine duty and installation

Identify whether the steam turbine serves mechanical drive or power generation. Preserve the complete machine type and serial number; published portfolio designations include SC, SAC, SNC and SANC. Use the installed machine’s own documents when requesting internal components or assemblies.

For a new unit, provide the project steam conditions, required shaft duty and installation arrangement. Include inlet and outlet conditions and any project-defined extractions or admissions. Keep distinct operating conditions separate and retain the original units and accompanying process documents.

For replacement equipment, show retained connections and mounting requirements. For parts, identify the housing, rotor or auxiliary assembly to which the item belongs, using its original reference and drawing. Independent auxiliary devices require their own markings and component lists.

Centrifugal, axial and reciprocating compression

MCL denotes a horizontally split compressor family and BCL a vertically split family. PCL addresses pipeline compression, ICL integrated motocompressor arrangements, and SRL another compressor family.

These names identify the enquiry direction; the complete configuration remains tied to the actual machine records.

For new compression equipment, provide gas composition, flow, pressures, temperatures and project operating conditions, together with driver and layout requirements.

When modifying an installation, distinguish the changed process duty from the existing machine specification and identify which auxiliaries remain in service.

For reciprocating equipment, preserve the complete machine and assembly designation. API 618 process compressors, PH/PK hypercompressors and Hyrcel and VerHy 550 hydrogen solutions have different scopes.

A cylinder, valve or other component request should refer to the installed unit’s own drawing and parts list.

Expanders and associated equipment

Distinguish a turboexpander-compressor, turboexpander-generator and hot-gas expander. Provide the complete machine type, serial number and process equipment tag.

For a new package, identify the working medium, operating conditions, associated compressor or generator and the boundaries of auxiliary systems.

Maintenance components should remain linked to the specific serial unit and assembly drawing. Define the contents of the requested assembly and show retained interfaces. Independently marked monitoring or auxiliary devices need their own identification alongside the general expander documentation.

For several operating conditions, use separate rows rather than combining values from different conditions. Maintain the relationship between each process condition and its required equipment arrangement, keeping revised project requirements distinguishable from the records of the installed machine.

Parts lists, documentation and receiving

A practical procurement table contains the machine tag, complete type, serial number, assembly reference, drawing item, quantity and attachment name. Group parts by their machine and identify the contents of any requested kit.

Keep seals, bearings, rotating elements and independently identified devices under their applicable references.

List document and receiving requirements before ordering, retaining any language, marking and equipment-association requirements. When quantities or scope change, issue an updated list and mark the amended lines.

On receipt, compare markings, contents and quantities with the agreed specification and retain the documents with the installation records.

To start selection, send the machine nameplate, required scope, marked drawing and quantities, together with a work contact and delivery destination. For complete equipment, add the project data sheet and identify existing components that are intended to remain in the installation.
