Proposal of the plan of action

The engineering study: sizing up the chosen solution encompassed in a plan of action

> Missions > Engineering

Once the strategy is defined, a long term roadmap is set (on a global perimeter for various sites, and eventually different countries), the diagnosis precisely carried out, the action plan (generally covering four years, the period between two regulatory energetic audits) includes several initiatives requiring investments or not

They are related to the replacement of equipment or to the implementation of an option on equipment. Coming from Lean Management, the technique of the five ‘whys’ can identify the real needs and motivations.

The first phase of study, whose purpose is to correctly analyse the actual need and future evolution, will allow to scale , as precisely as possible, the initiatives to be implemented on a site in order to choose the best technical solutions and associated suppliers. The main challenge is not to overinvest, all while guaranteeing the reliability, sustainability and maintenance of the chosen solution.

Measures must be taken and correlated with the activity on site, supported by discussions with the developers, the operators and the users of the site, to identify both their expectations and their constraints.

The adequate optimisations are then proposed in order to maximise the saving related to the chosen solution and finalise the budget encryption as well as calculating the return time to obtain the validation from the top management and eventually from third-party financing.

Are linked to the reconsideration of a specification, to the definition of an operating or maintenance procedure, or a change in operators behaviour.

To redefine needs by using techniques from “Redesign to cost”, for instance, R&D, marketing and commercial poles must be involved in order to rethink, conjointly with the production, a specification respecting the product characteristics and customer expectations.

To optimise maintenance or operating procedures, it is fundamental to involve the field operators in defining precisely the solution.

During an engineering study, Orygeen is responsible for:

Determining real needs

Ensuring scenarios are not blown out of proportion

Optimising the existing and proposed solutions to the maximum

Establishing a budget for the top decision management

Building the possible third-party financing solution

Preparing the subsidy and energy certificate applications

Orygeen can also intervene on existing specifications as well as on the basis of an offer made to a customer to maximise saving on the CAPEX and improve the return time all while increasing the performance of the implemented solution.
