Engineering and Design

OPSYS provides the complete engineering scope of work or part of such scope that is required by the individual client, including:

1 . Feasibility and Cost Studies

In this important phase of the project OPSYS will determine the nature of the project, the total project cost for budget purposes and the execution strategy. Work includes:

  • Definition of requirements
  • Identification of Economic Benefits and Priorities
  • Identification of Alternative Processes
  • Preparation of the Preliminary Estimate
  • Preparation of the Execution Plan
  • Preparation of the Design Basis and Planning Report

2. Basic Design Packages

OPSYS through its team of Engineers has proven to be a competent in executing Basic Engineering Design services. The Basic Engineering comprises the following activities:

  • Determination of the plant structure
  • Planning of the installation, construction and automation of the plant or unit and the use of apparatus and machines
  • Drawing up of the P&IDs
  • Definition of the equipment, technical data sheets ands lists of the various class classes are created
  • Layout and installation planning
  • Designing data input are being made available for the ordering procedures
  • The functional diagrams for the main tasks to be handled within the control technology are worked up in connection with the system description
  • Electrical consumptions of the plant or unit are determined.
  • Specifications documents are created
  • Risk assessments are carried out for the plant or unit and safety concepts are developed

3. Front- End Engineering Design (FEED)

OPSYS through its team of Engineers has proven to be a competent Engineering entity able to execute Front End Engineering Design services. This work would typically begin after the Design Basis has been set and includes but not limited to the following:

  • Engineer design data
  • Project specifications
  • Project key equipment data sheets
  • Process flow diagrams
  • Piping and instrument diagrams
  • Equipment sizing and specifications
  • Electrical single line diagrams
  • Plot plans

4. Detailed Engineering

OPSYS's team of Engineers with their knowledge, experience and competence are in position to offer Detailed Engineering services which includes but not limited to the following:

  • Detailed Engineering drawings e.g. mechanical equipment, piping, electrical, instrumentation and civil
  • Follow-up of detail engineering activities of other parties.
  • Preparation of job specifications in compliance with project requirements, laws and directives.
  • Technical support to construction supervision for the proper implementation of the detail design and specifications.
  • Requisitions and specifications for all equipment and materials
  • Technical evaluation of tenders
  • Approval of the vendor drawings
  • Preparations of construction sub-contract packages
  • Inspection of vendors' and contractors' fabrication
  • Factory acceptance testing of the equipment
  • Preparation of operation manuals

5. Process Engineering

OPSYS process Engineers have diverse experience. Leading edge software for process simulation, including multi-phase pipeline simulation and component based process simulation that are used by engineers worldwide are utilized.
