Diesel - light and heavy fuel oil

  • You provide us with the following :

    Technical data :

    • The overall layout plan of the site with the location of the various buildings and mechanical equipment
    • The scope of work carried out by the mechanic, the civil engineer and the electrician
    • List of the consumers (Auxiliary Turbines and site common services)
    • General distribution single-line diagram: HV/MV/LV
    • Site environmental constraints (ambient temperature, seismic level, keronic level) and statutory requirements (limiting pollution level, noise, discharges, etc.)
    • Specific technical constraints (equipment’s fire behaviour, maximum short-circuit level, direct current and emergency distribution equipment’s range, fitted spares, etc…
    • Required level of redundancy and automation (fully or semi-automatic)


    Standardisation and contractual data :

    • Applicable standards (IEC or others)
    • The contract’s contractual data (commercial and legal terms and conditions)
    • Suppliers or subcontractors imposed or qualified


    The project completion schedule

    • PLCs, servers, communication network, main supervision equipment and switchyard
    • MV/LV Bus ducts, earth cables, power distribution, monitoring & control and fibre optic cables
    • Communications equipment : video, access control, anti-intrusion, telephony
    • MV/LV Distribution boards and lighting distribution and low-power equipment
    • Direct and undulating current distribution systems, battery chargers)
    • Emergency gen sets

A concrete example

Diesel Power Plants in the French Overseas Departments (EDF PEI)

  • Turnkey construction of 3 Diesel power plants, running on heavy fuel-oil, each power plant being equipped with 12 engines (18 MW unit power) – sites: Guadeloupe, Reunion Island, Martinique
  • Contract handled, within the framework of a Consortium, with a Diesel engine manufacturer (MAN) and a Civil Engineering firm (Eiffage)
  • Find out more

    The challenge :

    Building three power plants at the same time on different sites, in line with the contractual deadlines (less than 36 months)


    Requirements fulfilled :

    • Single Project Management for all 3 sites
    • Organisation of the engineering by trade,  dedicated teams for :
      - power & lighting/distribution networks architecture
      - communications
      - monitoring / control /supervision
      - wiring and installation
    • Each team handles the engineering for the 3 sites at the same time (with standardisation and productivity in mind)
    • Use of a joint software platform for the Consortium members (data base)
