01  /  SERVICE DIVISION

Mechanical services
& rig support

Eight capabilities that cover a mechanical asset from the day it is installed to the day it is stripped — delivered on your site, offshore, or in the workshop.

02  /  OVERVIEW

Technical competence, applied where the equipment actually is.

Mechanical work fails for predictable reasons: the duty was never established, the alignment was never recorded, the fault was treated as a part rather than a mechanism, or nobody wrote down what was found.

Our services are built to close those gaps. Each one begins with an assessment of the actual operating condition, runs under a written method with defined hold points, and ends with a record you can use — not a verbal handover on the way to the gate.

The scope below can be taken individually or combined into a single mechanical support arrangement covering your asset list.

04  /  ENGINEERING

Mechanical engineering

Design, analysis and technical support sized against the real operating envelope rather than a catalogue assumption.

  • Mechanical design and technical specification
  • Failure investigation and root cause analysis
  • Component sizing, selection and material review
  • Modification and upgrade engineering
  • As-built documentation and technical drawings

05  /  RIG & INDUSTRIAL EQUIPMENT

Planned around the window you actually have

Rig and heavy industrial work is bounded by access, weather and the cost of every hour the asset is down. The engineering is finished before the crew mobilises — scope, tooling, spares and manning agreed against your window, not against an ideal schedule.

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

06  /  MAINTENANCE & INSPECTION

Condition first, then work

Maintenance is only worth what its record is worth. Inspection is only worth what it changes. Both are delivered with a written finding, not a verbal reassurance.

07  /  FABRICATION & SUPPORT

Fabricated to fit the installed condition

Most industrial fabrication fails at the interface, not the weld. Where the drawing and the installed reality have diverged, we survey the actual geometry before cutting material.

  • Structural steel fabrication and repair
  • Pipe spool fabrication and pipework modification
  • Welding to procedure on carbon and stainless steels
  • Machining of shafts, sleeves, bushes and housings
  • Skids, frames, guards and bespoke components

08  /  SECTORS SUPPORTED

Where these services are deployed

01

Oil & Gas

Drilling support, production equipment and pressure systems across upstream and midstream operations.

02

Energy & Power

Rotating equipment, turbine auxiliaries and balance-of-plant mechanical systems.

03

Industrial Manufacturing

Production line machinery, conveying systems and plant mechanical infrastructure.

04

Heavy Equipment

Hydraulic systems, gearboxes, drivetrains and structural repair on heavy plant.

05

Processing Facilities

Pumps, compressors, valves and pipework serving continuous process operations.

06

Marine & Offshore

Deck machinery, mooring equipment and offshore structural mechanical support.

09  /  QUALITY PROCESS

Every job, the same sequence

Hold points agreed before work starts, signed off as they are passed

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.
