NEC follows international project management standard methods for all its projects.

A Project Manager is defined as the person responsible for the success of the Project after Contract Award, and provides a single point of contact with the Customer regarding the execution of the project.

Our Project Management system provide for a Project Execution Plan that details and coordinate the different phases of the Project; it usually includes: Project organization, Schedule, Communication plan, Engineering plan, Procurement Plan, Construction execution plan, Logistic Plan, Project Control plan, Contract administration plan, Quality Plan, HSE Plan.

Periodic progress reports are provided to customer in order to share status, critical topics, activities planned and achieved.

Though NEC process department we can offer to our Clients the development of a preliminary process study for several kind of plants, showing product rates, waste streams and providing good estimate of required utilities.

The process study can lead to project feasibility study that include:

 Product market study support
 Material balance and block diagrams
 Layout study for the new plant
 Equipment list
 Utilities requirement
 Preliminary CAPEX study
 Preliminary schedule
 Preliminary OPEX study

NEC can develop process engineering for several kind of plants through its process department and the use of process simulation tools.
The issue of Process Flow Diagrams and Process & Instrumentation Diagrams is typical a part of our engineering scope.

Through years of experience we developed working partnership with several international process licensor that we cooperate with every time we need a project under license.

Oil / grease blending plants, Used Oil Refining Plants, Fuel Treatement plants are our specialty knowhows that we can develop independently.

After process engineering execution, we’re structured to carry out base engineering steps: instrument implementation in process drawings, general layout studies, equipment & structures sizing, electrical sizing, control system philosophy, preliminary piping and cables ways, preliminary foundation sizing.

The key output of basic engineering are purchase specification to be included in our RFQ packages for procurement activities. Quality (inspections and documents) requirement are also defined jointly with Quality department.

Main deliverables of detail engineering are the following:

 Mechanical equipment design
 Civil/Structural design
 3d piping Engineering and Stress analysis
 Piping & Electrical Hook – up development
 Electrical equipment design
 Instrumentation and control

The purpose is to define Material Take Offs that allow the Procurement department to purchase bulk materials for construction.
Construction engineering, with issuance of isometrics drawings, piping & cable ways layout, erection plans is the following step of activity.

It is NEC policy to purchase equipment, materials and services within the free world market which offers the most economical cost, taking into consideration specifications, schedule commitment, quality and reliability.

After Vendor list definition and Request for Quotation packages preparation, the Procurement department open the inquiry phase towards selected vendors, monitoring and controlling progress through daily management of Procurement Execution Plan.

Once proposal are received, these are routed to project engineering for technical alignment and tabulation: after scope of work is aligned on all proposal, procurement department starts the commercial negotiation with Vendors.

The issuance of purchase order is the trigger for expediting, done both through request of periodic progress reports from vendors and shop visit to critical equipment suppliers.
Quality control inspections are often coordinated with inspection visits to assure the most effective control on Vendor’s process execution.

The construction strategy will be finalized during the engineering phase in the construction execution plan. Main execution issues addressed are the following:

 The commitment of NEC Project Team to effectively implement the Safety, Health and Environmental objectives set for the Project.
 The key members of the construction management team, with good practice and local experience will be assigned to bring this Project to a successful conclusion.
 Engineering milestones to meet key construction objectives will be defined and agreed with the Project Manager: the construction plan key objectives will be defined and a risk assessment approach will be applied.
 The construction plan will take into consideration constraints such as on the availability of labor required for the Project.
 The development of the contracting plan and the optimization of pre-assembly and fabrication concepts within economic and transportable limits will keep onsite labor to a minimum level.
 Ensuring constructability concepts are fully and effective implemented.
 Take on board lessons learned from other similar projects.

After review of the General Layout the scope of work is divided into definition areas: these areas will be treated as work packages to be further detailed. The priorities will then be followed in all phases of engineering, procurement and construction leading to a phased sequence of completion.

Construction knowledge, experience and lessons learnt from previous projects will be applied to all stages of Engineering, Procurement and Construction to maximize construction efficiency.
The Site Construction Manager will be responsible for preparing a preassembly/module plan that will be incorporated within the Project Execution Plan: suitable packages / modules will be identified as vendor’s units, designed by vendor with NEC engineering coordination.

Modularization approach, which is the mindset of NEC during engineering phase, is usually highly effective in reducing erection lead time and overall project cost.

The completion activities of a new hydrocarbon processing plant consist of a series of various checks carried out just before the plant is start-up. The aim of these verifications is to ensure, as thoroughly as practicable, that every piece of equipment are built and operate as per design.
These completion activities are separated into two phases, Pre – commissioning and Commissioning, this split roughly corresponding to static and dynamic tests phases respectively. The completion activities are followed by the Start-up phase itself, corresponding to the introduction of the hydrocarbon feedstock into the plant.

The Precommissioning phase includes three main types of field activities:

• Conformity checks: Carried out on each item of equipment or component, such as instruments, packages, motors, cables, vessels, etc., to verify visually the condition of the equipment, the quality of the installation, the compliance with Project drawings and specifications, VENDOR’s instructions, safety rules, codes, standards and good practice.
• Static / de-energized tests: Carried out on equipment to ensure the quality of a number of critical components. This “cold” testing concerns all disciplines, e.g. calibration of ESD instruments, machinery alignments, setting of safety valves, pressure testing of piping, cables continuities, etc.
• Piping Test (Test Pack): Carried out on pipes work, air or water flushing, pressure test (hydrotest).

The Commissioning phase essentially includes the three following categories of tasks:

• Dynamic verifications that for each Plant elementary electrical, telecommunications, and instrumental function, performs properly according to its design criteria. Typical examples of such tests are electrical motors uncoupled runs, instrument loops tests, electrical breakers operation. The energization of the electrical distribution network is part of this activity.
• Running-in and on-line tests for a significant period of the plant utilities (electrical, air, HVAC, water, crane, etc.) and, wherever applicable, of the main process equipment in closed loop with inert fluids.
• Piping and Vessels Preparations: A number of activities related to, such as piping drying-out, process leak testing or loading of various chemicals and catalyst.

The Start-up activities begins with the final preparation to the introduction of the feedstock into the plant and consist of a series of various tests carried out during the plant is brought on line. The aim of these tests is to ensure that all equipment operate normally and securely. The technical assistance for Start-up from Commissioning team may be required. The field activities consist of two sub-stages:

• Operate prior oil/gas in: Line up pipework and vessels (valves, PSV, interlocks, etc.), carry out final safety tests with the provision of associated documents (safety procedures, isolation, inhibition, HC introduction certificate if needed, etc.).

• Operate after oil/gas in: bring the process in operation with Oil/gas in, water injection.
Ensure the ramp-up and carry out the Performance tests to prove the plant and equipment are performing as per design capacities and can deliver the products within specifications.

In order to carry out a smooth transfer, NEC Start-Up team shall follow-up, assist, and check Site Acceptance Tests and appropriate Commissioning activities (leak test, Running-in of the plant utilities, Oil or gas-in preparation, ESD demonstration, etc.).

Project Management System

NEC have a stage project management system with project review gates and deliverables that are the base for an effective planning, execution and control of a project. The focus is to control project quality, time and to consistently provide cost-effective solutions to clients.

NEC PROJECT MANAGEMENT SYSTEM (PMS) is organized as follows:

The Project Execution Plan identifying the organization, interfaces, authorities, reporting levels and the execution method for the successful completion of the project.

The Project Quality Plan, defining the overall Quality Assurance & Control procedures, ensure that all the contracted activities are planned and performed in a properly manner with the purpose to achieve project quality requirements.

The Project Procedures, covering the scope of the contracted work shall be selected from the Client Standards / NEC’s and amended, where necessary, to become project specific.

Codes and Standards experience, ensuring that design, procurement and construction meet the requirement of regulatory, health, safety and environmental aspects.

Project Quality Audits and Review meetings allow to identify solutions for any problem detected and to highlight improvement areas.
