Engineering & Design

Engineering & Design

Top5Five is an innovative hi-tech, engineering, procurement and construction company serving Oil&Gas, Energy and Manufacturing Industries all over the world. In the spirit of Industry 4.0, our SMART engineering solutions combine cutting edge technologies (e.g. modelling and tracking technology, sensors and devices) with the Internet of Things (IoT) and cyber-physical systems. We are the best partner to refer to design “intelligent” tailored-made solutions to enhance one’s competiveness and efficiency in nowadays global markets. Our Engineering & Design services include:


Process Design

The first step of the design of a plant typically includes:

  • The selection of main unit operations and process modelling by means of simulation programs;
  • The production of heat and material balances;
  • The preparation of process flow diagrams (PFD) showing equipment, process connections and main control loops;
  • The preliminary sizing of the equiment (Equipment Summary);
  • The assessment of utilities consumption (Utility Summary);
  • The Process Description;
Detailed Engineering Design

FEED documents are further developed in the final design phase, until they reach the “Issue for Contruction” level of detail. The coordination of the relations between Vendors, EPC, Contractor(s) and Client ia also included in this category of services.
