We employ experienced Chartered offshore oil & gas engineers and designers to provide an engineering service you can depend on. Our approach to business eliminates overheads associated with many larger EPC contractors to provide you with an efficient cost effective electrical design solution.

Our highly experienced engineers can provide FEED study / power system modelling and design services to support your project whether it’s a bespoke solution or making modifications / adding additional equipment to your existing power system.


Typical Projects:

The majority of Operators and Service companies are seeking a low cost base solution for minor project work that does not involve all the additional costs associated with large EPC companies. EPS can help you with a low cost engineering & design for the following typical example projects:

  • UPS replacements.
  • Arc Flash studies
  • MCC / Switchboard replacements
  • Helideck lighting to CAP437 requirements
  • Temporary Diesel Generator integration into the exiting power system
  • Power Management System modifications (also for decommissioning)
  • Lighting additions / modifications
  • Trace heating modifications / extensions to existing circuits.
  • Electrical supplies to pump skids.
  • MCC / switchboard cubicle specifications.
  • Power System Modelling

In addition to the above work scopes we provide comprehensive work packs for example detailed installation method, cable routing details, materials and test certificates. Once commissioned we’ll produce the as built drawings.


  • Temporary Diesel Generator integration into existing power systems
  • Power Management System modifications (inter platform power generation)
  • Electrical decommissioning load lists (schedules)
  • Migration of power supplies and UPS supplies
  • Power System Modelling
  • Reduced protection settings (for reduced power generation capacity)

Drawing consolidation work:

Many platforms over the years have undertaken refurbishment or long life extension projects involving the creation of additional drawings that are either no longer required or confuse offshore personnel as to the latest revision. EPS can help you consolidate these drawing to assist your technicians:

  • Utilising existing drawings and combine them into one ‘up to date’ drawing e.g. key single line drawings.
  • UPS key single line drawings.
  • Topside subsea key line drawing consolidation.

Specialist Consultancy:

Using electrical engineering software such as SKM Power Tools, ETAP, ERACs, IPSA or DigSILENT our electrical engineers can provide you with a study report for your power system.

Whether it’s a power system study for the entire platform or FPSO electrical distribution system or a modification / addition to the electrical system EPS can provide you with the following technical services:

  • Load flow analysis studies.
  • Short circuit studies.
  • Transient Motor Starting Studies.
  • Harmonic analysis.
  • Protection co-ordination.
  • Arc Flash and switchgear risk assessments.
  • Independent project cost estimates.

Equipment documentation:

If you’re looking to replace some existing equipment and require a data sheet or specification to purchase this equipment then EPS can provide this technical service; typical documentation for projects may include:

  • Replacement emergency power generation panel specification, FAT scope, installation work scope.
  • UPS system specification, data sheet.
  • LV and HV switchboards / MCC’s, specification, protection schedule, FAT scope.
  • DC Chargers specification, data sheet.
  • Equipment installation specification.
  • Cable jointing specification.
  • Condition monitoring specification, data sheets.

Additional services:

  • Electrical, Instrumentation & Control offshore surveys.
  • Factory Acceptance Testing (national and international).

Typical projects include:

Providing cost effective electrical design solutions for:

  • Helideck lighting electrical design to meet CAP437 requirements.
  • Trace heating design for example additional Pressure Transmitters.
  • Lighting design and power supplies for example a new platform / skid.
  • Supporting refrigeration specialists to supply the new refrigeration control panel / skid.
  • Providing supplies to and from new UPS equipment.
  • Decommissioning – removing and rerouting power supplies for decommissioned and remaining operational plant.

All of our Chartered engineers have offshore experience and certificates for offshore wind and offshore oil & gas assignments / projects including BOISET, MIST and EBS.
We collectively bring together Chartered engineers and experienced designers which have many years experience working in oil and gas hubs such as Aberdeen and London. EPS Chartered engineers are accustomed to the offshore industry standards and practices working to strict EPS quality procedures and ISO9001.
