Engineering and project management

Engineering to design and optimise solutions and project management to ensure proper implementation

Accueil > Missions > Engineering

Once the strategy has been defined, a long-term roadmap has been set (on a global perimeter for several sites and possibly different countries), and the diagnosis has been carried out, the action plan (generally for a period of 4 years, the period between two regulatory energy audits) groups together several initiatives that may or may not require investment. Some of these initiatives may require a feasibility study to validate their relevance before launching the design and engineering phase.

These are related to the replacement of equipment or the implementation of an option on equipment. Derived from Lean Management, the 5 Whys technique helps to identify the real needs and motivations.

The first phase of the study, whose purpose is to correctly analyse the current need and its future evolution, will enable the initiatives to be implemented on a site to be sized as precisely as possible in order to choose the best technical solutions and the associated suppliers. The main issue is not to over-invest, while guaranteeing the reliability, durability and maintenance of the chosen solution.

Measurements must be taken, correlated with the activity on the site, and discussions held with the operators and users of the site in order to identify both their expectations and constraints.

The appropriate optimisations are then proposed to maximise the savings linked to the chosen solution and finalise the budgetary costing as well as the calculation of the payback time to obtain the validation of the top management and a possible application for third party financing.

These are related to the redesign of a specification, the definition of an operating or maintenance procedure or a change in operator behaviour.

In order to redefine the need, using for example techniques from Redesign to Cost, it will be necessary to involve the company’s R&D, marketing and sales departments in order to rethink, in conjunction with production, a specification that respects the characteristics of the product and the expectations of the customer.

To optimise a maintenance or operating procedure, it is essential to involve the operators in the field in the precise definition of the solution.

Following the feasibility study, if any, Orygeen takes care of the following during the design and engineering phase :


Determine the real needs


Ensure that the possible scenarios are not oversized


Optimising the existing and proposed solutions as much as possible


Producing a costing for the top management decision-makers


Validate the specifications and draw up the terms of reference


Build the possible third-party financing solution


Preparing the subsidy and energy certificate files

Orygeen can intervene both on the basis of existing specifications and on the basis of an offer submitted to a client in order to reduce the CAPEX and improve the payback time while increasing the performance of the solution implemented.
