Rig Mechanical Support

Mechanical crews and engineering support for rig equipment — mobilisation, overhaul, repair and recertification support, planned around the operating window rather than against it.

02  /  OVERVIEW

What this service is for

Rig mechanical work is constrained by access, weather and the cost of every hour the asset is down. The engineering has to be finished before the crew arrives, not worked out on deck.

We plan the scope, tooling, spares and manning against your window, then execute under a written method with the hold points agreed in advance.

03  /  SCOPE

What is included

  • Drawworks, winches and hoisting equipment
  • Pressure control and handling equipment support
  • Rotating equipment overhaul and refit
  • Structural and deck machinery repair
  • Mobilisation and demobilisation support

04  /  APPROACH

How we run it

Constraint

The window is the design brief

Scope, tooling and manning are planned backwards from the time you actually have — not forwards from an ideal schedule.

Execution

Method before mobilisation

Method statement, risk assessment and hold points are agreed before anyone travels to the asset.

05  /  DELIVERY

The sequence this runs to

The depth changes with the size of the job. The sequence does not.

Assessment

Site attendance, condition survey and failure analysis. We establish what the equipment is actually doing before anyone proposes a fix.

Engineering

Technical solution defined against the operating envelope — loads, tolerances, materials and access constraints.

Planning

Method statement, risk assessment, parts, tooling and manning scheduled against your shutdown window.

Execution

Work carried out by mechanical technicians under a written procedure, with hold points recorded as they are passed.

Installation

Components installed to the written method — alignment, clearances and torque set against the drawing, with hold points signed as they are passed.

Commissioning

Controlled start-up and function checks under operating conditions, before the asset is declared ready.

Testing

Function testing, alignment verification and performance checks before the asset is handed back.

Handover

Documented completion — what was found, what was done, what was replaced, and what to watch.
