(Oil & Gas sector EPC Company) Inputs & Outputs in the V.D.U unit. • Input – Raw Crude oil • Outputs – (1)Light Naphtha (2)Heavy Naphtha (3)Kerosene (4)Vaccum Residue………,etc http://valveproducts.metso.com/neles/ApplicationReports/2721_Refinery/2721_02_01en.pdf 4 What is an EPC Company? How it What functions? functions?
• EPC ( Engineering, Procurement & Construction)
Chemical Piping civil mechanical electrical Instrumentation…. Procurement
(Department responsible for material purchase from vendors and inspects it) Construction
(Execute the Designed Phase) 5 Phases involved in our project
1. Client’s Requirements & Specifications. 1. Basic Engineering or PreDesign phase. 1. Detail Engineering or Design Phase. 1. Construction. 1. PreCommissioning. 1. Commissioning phase. 1. Operation and maintenance phase
6 Phases involved in the project
• Requirements and specifications: This involves the basic needs and requirements of the client in terms of Technical and Commercial. • Basic Engineering or PreDesign Phase: Conceptual phase begins, FEED Engineering( FrontEnd Engineering), Project planning and creating 3D CAD (Computer Aided Design) model as a common platform for all engineering departments. • Detail Engineering or Design Phase: Detailed working on FEED engineering, Designs are completed by every department, interdepartmental reviews, client reviews & safety planning. Leads to the creation of virtual 3D Model. Procurement is also a very important activity. 7 Phases involved in the project
• Construction: Basically the execution phase in which the 3D Model is actually constructed at site. Involves activities like construction management. It is the phase where most of the project cost goes into. Verifying the actual construction with that of the designed, Preparation of operation manuals, imparting training to the operators. • PreCommissioning: Making the plant ready for testing by • Commissioning: Making the unit functional by supplying the process fluid and generating the operating conditions. Safety issues are the main and must be taken into consideration. • Operation and Maintenances: After the hand over of unit, client can ask for operation and maintenance check of the unit as per signed contract.

• • •
Schedule delay Cost overrun Management issues • Design changes • Delay in placing the order • Late delivery at the site
12 12 Why were they unforeseen?
•Persons involved in the activity were in-experienced or somewhat lacks proper training. •Safety training was not properly imparted to the workers by the safety supervisor. Countermeasures
• There should be proper check on the safety norms to •
avoid accidents The coordination and communication between the client, contractor and vendor 13 13 The End
