Combined Heat & Power

EPS has recently (July 2016) been awarded the contract to design and build a new dedicated 11kV supply for a new Combined Heat & Power project. The project involves detailed design of a new 11kV switch room and substation, complete with earthing design and individual LV 415V supplies to each CHP plant. The installation will start soon after the detailed design has been completed and client approval.

The project also includes a transformer energisation study to satisfy the local Distributed Network Operators voltage dip requirements. The project requires 400 metres of High Voltage (11kV) cable, cable trench, below ground earthing and excavation, 11kV transformer, 11kV switchgear, LV Switchboard and small power and lighting. The gas fired wood chip CHP plant will be fully commissioned at the end of the year supplying homes and buildings in the area.

SP Energy Networks

An earthing design was carried out and successfully completed for SP Energy Networks wind turbine substation. The substation tied back several 1 MW wind turbines with each wind turbine having its own below ground earthing system including lightning protection system. Each wind turbine required its own below ground earthing system.

Dhabi Nortech

Over the years EPS has been providing ongoing engineering design services for Nortech Oil & Gas. Working for international clients based in the Middle East. Projects range from conceptual design studies for a new 11 kV ring main with approximately 15 km of cable and 5 off 11 kV Ring Main Units to be located within a petrochemical plant in the desert.

Ongoing support includes equipment specifications, cable calculations, distribution board specifications, UPS adequacy report, trace heating calculations, earthing design, general design Checking and Approvals etc.

EPS has a vast range of experience with Electrical & Instrumentation projects where larger EPC’s or Operators do not have the time or the personnel to undertake FEED or detailed design work.



Bluewater owns and operates a fleet of five Floating Production Storage and Offloading (FPSO) installations around the globe currently leased to oil & gas companies. EPS was requested to undertake a comprehensive electrical protection offshore survey of their Haewene Brim FPSO, the survey consisted of a 4 day period gathering details of electrical protection settings for the entire distribution network. EPS produced a total of 75 off schedules which were issued detailing the MV and LV electrical protection distribution system.

The up to date protection schedules were then used to create a comprehensive power system model with each protection device. This model was used to create a range of time current curves for a large number of individual circuits with a protection study report.

EPS provided recommendations based of on the findings from the protection report that would enhance the protection and increase the reliability of the electrical distribution system.

We’re currently undertaking an Arc Flash Assessment report complete with an Arc Flash risk assessment with recommendations of how to mitigate potential high energy arc flash using existing protection devices and how to protect their work force.

SKANWEAR in collaboration agreement with Engineering Power Solutions (EPS)

UK, 2016-Oct-28

• Embracing collaboration; world class companies strengthen working relationship
• Leadership, skills and innovation underpin strategic partnership agreement

SKANWEAR and EPS, have established a working relationship through an agreement to develop closer strategic collaboration to drive electrical safety, namely arc flash awareness and solutions across the globe.

The agreement covers the exchange of a wide range of products, services and skills across mutually beneficial areas to further improvements and developments within the global electrical safety arena.

With each company operating within similar sectors, the collaboration hopes to realise the benefits of combining the in-depth expertise from each business to challenge existing products, services, systems, processes and solutions and create an electrical safety solution that supports global companies looking to harmonise and standardise electrical safety policies and practises across their organisation.

Angus Long, Global Technical Manager for SKANWEAR, comments: “This agreement further formalises an excellent existing relationship between SKANWEAR and EPS, both leaders in our fields. We face a period of opportunity as organisations across the world are seeking to improve electrical safety standards. By working together on products, services and global working practices, we aim to realise the full benefits of global electrical safety solutions. This is an exciting development that will positively contribute to both businesses, but more importantly our clients and the value we add to them”

Both SKANWEAR and EPS will be hosting clients as part of the new partnership, involving them in specific electrical safety innovations we are developing.

Adrian Hall, Managing Director from EPS, concludes: “The scope of the collaboration is unlimited and will see us work closely together to optimise electrical safety solutions for industry. At a time when all stakeholders need to address the challenges global compliance brings, we believe such partnerships can make a significant contribution to supporting global companies in their drive towards consistency and standardisation”




The PetroSA FA platform exports gas to the Mossel Bay GTL plant, gas production from the FA reservoir had over the years been supplemented by FA satellites to the North West of the platform, E-M from the West, and the South Coast Gas (SCG) development from the Southwest.

The FO Development Project involved a Subsea tie-back to the existing FA Platform of five new production wells located approximately 40 km South East of the Platform. Once the project was completed produced gas, condensate and water was be piped to the F A Platform via a new subsea pipeline.

Engineering Power Solutions Ltd. was requested by to provide electrical engineering and design services. Twelve new electrical pump skids required a number of new power supplies to supply the new 30kW water injection, 30kW Methanol injection and 90kW transfer pumps from existing MCC’s (Motor Control Centres). The project required new lighting above and below a 20 metre long ESDV (Emergency Shutdown Valve) platform. New electrical supplies from existing 440V switchboards to supply the UPS (Uninteruptable Power Supply) system and subsea EPU (Electrical Power Unit) were also required.


The North Sea Oil & Gas operator Maersk Oil was concerned about the reliability of their emergency diesel generator to provide power for their critical loads in the event they lose the main gas turbine power supply. Typically, emergency generators are periodically tested to ensure that they are operationally sound and can “pick up the load.” Because the diesel generator tests were performed on a weekly basis through an automated system, the emergency generator failed to start on a number of occasions, for an FPSO this could have been a potentially dangerous situation leading to a prolonged black out and loss of production if the generator was called for in a real emergency event.

The faulty generator control panel components were replaced, however during a further investigation it was found that many of the existing components within the generator control panel were found to be obsolete. Engineering Power Solutions (on behalf of Petrofac) were requested to produce a detailed report on the condition of the generator control panel. The findings of the report showed that the client could either refurbish the existing panel or replace the complete panel both during a shutdown. In order to minimise the shutdown period it was decided to replace the complete panel.

EPS produced the following necessary documentation for enquiry and enable equipment purchase:

  • Site survey
  • Schematic drawings
  • Cable routing drawings
  • Control panel specification
  • Purchase requisition
  • Factory Acceptance Test procedure

This solution modernised the emergency generator control system to enable the vessel essential power supply system to be in service for a further 20 years.
