Engineering scope

The expertise your
next project needs.

Engage us for a defined task or a coordinated package. We support equipment manufacturers, fabricators, EPC contractors and project teams with deliverables matched to their design basis.

Tools aligned to the task

Useful deliverables.
Clear file requirements.

The software platform, version, project standards and handover formats are agreed at the quotation stage.

Final deliverables depend on the agreed scope and available inputs. Native-file handover and client project-database access are confirmed before work starts. Software names identify the proposed tools; they do not imply vendor affiliation.

Flexible engagement

Design support that fits
the way you work.

Keep your own manufacturing route or ask us to coordinate a wider equipment scope. Design services can be commissioned independently.

A defined assignment

One task. A clear output.

A vessel calculation, piping stress study, skid design, 3D assembly or drawing update—with inputs, deliverables and review cycles agreed in advance.

A coordinated package

From layout to detailing.

Connect equipment, piping and structural deliverables within one agreed engineering scope, with interfaces and responsibilities defined.

Support for your team

Additional project capacity.

Discuss modelling, detailing or documentation support for a project phase, aligned with your standards, file structure and review process.

How we deliver

Defined inputs.
Traceable decisions.

We establish the design basis and document list first, so review and handover stay focused on your project requirements.

01 / UNDERSTAND

Review your brief

Identify the duty, available drawings, codes, loads, interfaces and required completion date.

02 / AGREE

Set the scope

Confirm deliverables, assumptions, exclusions, software, revision cycles and schedule.

03 / DEVELOP

Design & coordinate

Prepare calculations, models and drawings, with checks and client review at agreed stages.

04 / HAND OVER

Issue the package

Close agreed comments and issue the controlled deliverables in the confirmed formats.

Design-only enquiries welcome

Tell us what
you need engineered.

Share your scope and the information you have. We will review the required inputs and prepare a proposal covering the design work, deliverables and schedule.

Can we engage you for design only?

Yes. You can commission a defined design, modelling, analysis or detailing scope without purchasing equipment from MechOilfield. Manufacturing and supply can remain with your selected vendor.

Can you work with our existing drawings or models?

Yes, subject to review of the file condition, software compatibility and available design inputs. Share the current files and required changes so that we can define the update scope.

Which codes and approvals are included?

The applicable code and edition are agreed for each assignment—for example, ASME Section VIII Division 1 for relevant pressure vessels, ASME B31.3 for applicable process piping, and the specified structural standard for skid work. Independent approval, statutory certification and equipment stamping are separate requirements and must be identified in the enquiry.

Will we receive editable files and calculation reports?

The proposal will identify the reports, drawings and editable or neutral-format files included in the handover, together with the review cycles and revision scope.
