Thermal Plants


Facing the English Channel from France


Our contribution to EDF modernization project


10 years using PED 97/23/EC - Pressure Equipment Directive, are we going to change rules in Europe?

Forecasts on energy production from traditional sources see gas overcoming coal and getting close to oil in terms of global demand within the next 20 years (gas demand increase is estimated around 2% per year) as the result of the need of reducing CO2 emissions and consequent higher prices of the most polluting energy sources.


Despite this, the conventional sources will still lead the energy production. The EDF group is facing these issues and has started a sustainability program aimed at integrating new technologies applied to traditional energy fonts, increasing efficiency and reducing emissions, with renewable energy production.


For that reason EDF has been carrying out an extensive modernization and development program on its fossil-fired fleet, for instance some actions are taken in Le Havre, overlooking the English Channel, where the coal-fired 1,450 MW electric power plant is operating since 1963. The plant produces 1% of the electricity produced by EDF in France, the 20% of the electricity consumed in Normandy. Furthermore EDF is developing in the same site a CCS (carbon capture and storage) demonstration plant.


conditioning system, control and automation system, the boiler area's electrical power distribution plant, flue gas ducts for a total extension of more than 100 meters up to the existing stack (total height of 230 meters).


The project is very complex in terms of time scheduling, involvement of different competencies and coordination of actions; for this reason it is managed by a senior project manager, who leads a team of 12 skilled people from different departments: project and process engineering, mechanical and CAD engineering, instrumentation and control, automation, quality, site engineering, commissioning.


Bono Energia is developing the engineering package with internal resources.


The technical department, composed of 27 engineers and technicians, will provide the studies for plant layout, foundation drawings, mechanical assembly and fabrication package, P&IDs and process flow diagrams, electrical, instrumentation and automation engineering, commissioning procedures and reports, quality control and use and maintenance manuals.


From 30 May 2002 the pressure equipment directive is obligatory throughout the EU.


The directive provides, together with the directives related to simple pressure vessels (2009/105/EC), transportable pressure equipment (99/36/EC) and Aerosol Dispensers (75/324/EEC), for an adequate legislative framework on European level for equipment subject to a pressure hazard.


The PED directive arises from the European Community's Programme for the elimination of technical barriers to trade; its purpose is to harmonise national laws of Member States regarding the design, manufacture, testing and conformity assessment of pressure equipment and assemblies of pressure equipment.


BONO Energia supplies two auxiliary water tube boilers like these for the new power plant of EDF in Le Havre, France


Bono Energia is contributing to EDF program with the supply and installation of two auxiliary water tube boilers, fuelled by fuel oil (with the possibility to change, in the future, the fuel to natural gas), with a total capacity of 130 t/h of superheated steam.


The project witnesses the evolution and the strengthening of the collaboration between Bono Energia and EDF: indeed the scope of the supply is greatly increased compared to the previous projects realised for the French thermal plants of Blenod and Martigues Ponteau, West Burton in UK and Phu Ny in Vietnam since 2002. In those three projects Bono Energia worked in partnership with Edison engineering, the system integrator; in this case the job will directly be developed by BONO for EDF CIT (Centre d'Ingénierie Thermique).


In previous jobs the scope of supply was limited to the boiler package coupled with related accessories, now it is a complete turn-key project that includes the whole engineering of the system, shop manufacturing, on site delivery of all equipments, on site installation, commissioning and start-up. BONO will provide the deaerators (furnished by the sister company Artes), the feed water chemical


The boilers will be partially pre-assembled in Bono Energia's production facilities in Peschiera Borromeo (close to Milan) and then delivered by sea to Normandy; thus the design will be very focused on the optimisation of the assembling sequence and on loading/unloading activities, in order to minimize on site work.


The delivery of the plant is foreseen for the beginning of 2013, while the installation and start-up will be completed in 2014.


It therefore aims to ensure the free placing on the market and putting into service of the equipment within the European Union and the European Economic Area.


The Directive concerns items such as vessels, pressurised storage containers, heat exchangers, steam generators, boilers, industrial piping, safety devices and pressure accessories. Such pressure equipment is widely used in the process industries (oil & gas, chemical, pharmaceutical, plastics and rubber and the food and beverage industry), high temperature process industry (glass, paper and board), energy production and in the supply of utilities, heating, air conditioning and gas storage and transportation.


After 10 years the European Commission is evaluating the performance of the directive. The evaluation is being conducted by CSES (Centre for Strategy & Evaluation Services). A report on the evaluation will be made available on the DG Enterprise and Industry website from late- Autumn 2012.


As part of the evaluation, CSES is collecting information from the stakeholders about their perceptions of the performance of the Directive; notified bodies, government authorities, standardisation bodies, pressure equipment manufacturers, end users are strongly invited espress their opinion filling in the questionnaire:

The Directive was adopted by the European Parliament and the European Council in May 1999; it came into force on 29 November 1999, from that date until 29 May 2002 manufacturers had a choice between applying the pressure equipment directive or continuing with the application of the existing national legislation.
